View Full Version : TravelWide Repair Question

I have managed to break part of the retaining ring that holds the helical mount onto the camera body of my TravelWide. On my bench right now is a ~120 degree semicircle of 1/4" wide plastic with two screw holes broken out.

I am sure that this has happened before to some other TW user: Can it be fixed? If so, what is the best way?

Don't really want to send it all off to SK Grimes for a custom machined ring in Titanium.

DIY suggestions?

What tools do you have? Plastic is quite easy to cut and shape with files.

p.s. If the plastic is ABS, then gluing it with acetone can be as strong as the original.

Price the replacement part from TravelWide first... They might give you one at little to no charge...

If the part broke to begin with, there was a weakness or defect... Fixing the broken part should be a last ditch effort, as the repair might/might not hold, and you have to get it right the first time...

Thank you Steve, sounds like good advice. My tool set rides in a nylon pouch on my belt labled "Leathgerman". The Wave model has two knife blades, file, saw, Philips and flat screw drivers can opener , finger nail sciczors and plyers.

I weas hoping for a fix that could be done with a hot glue gun or via 3D printing from an online shop.

Not sure Wanderlust is making parts. Ben Syverson has been very quite and hard to contact for quite a while so I would doubt that one could obtain any replacement parts. When I try to log onto their site I get a security warning so have not kept up with any progress he has made with continuing to make the TravelWide 90. I know that he did mention in the comments section of the Kickstarter page that in the future he may choose to make the retaining tabs out of aluminum, I would think a lot of those original tabs have broken off ears.

Aluminum would certainly be a good choice.
Some aluminum alloys are almost as strong as steel, but still light weight.

You could certainly 3D print the part, but without a redesign I'm sure it will fail around the screw holes again. It looks like there's some room to make the screw holes a bit stronger by going thicker, though that may necessitate some longer screws.

How exactly did it fail?

Drew Bedo
14-Apr-2017, 12:24
While packing with other gear, the mounted lens and helical were compressed axially towards the film plane. The screw holes on one side were ripped out.

I would think that if this part were made from aluminum it wouls be an effective mod.

I know it has been a few months, but I've just had the exact same thing happen, and for the exact same reason. That retaining ring is flimsy! Did you ever come up with a solution or are you dead in the water?

Drew Bedo
14-Jul-2017, 14:41
Back-burner now but on the to-do list. We went on vacation anyway and had a good time. Now facing other things . . .but its still a want-to-do project.

Tagging this thread. My TW has two broken screw holes as well, but on diagonal ends. It works fine with just the two other screws tightened.

I need to take it apart again and try just superglueing the holes. I believe they just cracked and did not actually break off.

I'll let everyone know once I hear back. Maybe we aren't the first to request replacement parts, and they already have a blueprint on file? Fingers crossed

Steve Goldstein
16-Jul-2017, 14:15
I may have a file for 3D printing this part - ISTR that someone posted it somewhere, possibly APUG. I'll check when I'm back at my home computer. Maybe SKG could use this to extract dimensional info.

EDIT - I have .dxf drawings for the arc-shaped pieces as well as for a circular retaining ring but I can't vouch for their accuracy.

Drew Bedo
16-Jul-2017, 17:46
The part would probably be more robust if made from Aluminum or Brass rather than plastic.

I would be in for one. I'm very careful with my TW and have it cased such that no pressure can be applied to the lens but it happens.

I have a TW with the same repair issue. I would guess that there are others out there too. No sense in sending it in if they are still working on a fix.

Are we talking about a jam-nut or a lens flange? Chances are that TravelWide's part is standard and easily replaced with a steel part. If not a jam-nut or flange, then what is it, please? Any snapshots available?

If it is some unscheduled odd part, then Glen at http://www.glennview.com/ might help.

These parts mount to the inside of the camera with very small screws and the screw eyelets get broken when there's too much friction with the helical.

Thank you, Jon. I had no idea. Crazy engineering. Certainly a metallic replacement is in order. They appear symmetric, so only one part duplicated is necessary - no?

Still waiting to hear. It's been over a month.

Questions:

- Is this a common problem?

- are replacements not available from the manufacturer?

- How thick are those, and do they need to be that thickness in order to work properly?

- Still wondering what the SKG quote might end up being, and what material they intend to use for it.

Drew Bedo
12-Sep-2017, 16:20
In my opinion, this is a design deficiency in every TW camera. Most folks seem to be more carweful with their TW than I have been.

he TW was a Kickstarter project and I understand that there has not been a follow-up or second mfg run. No. there are no spare parts available. Check out the 250+pagrthreadontheKickStarter forum for the back-story

Not sure what "thick" means for this discussion. The walls of the screw holes are to thin . . .?

I would like to know the SKG price too. Then I'd like to know who they job it out to and contact them for a direct and lower quote.

12-Sep-2017, 16:33
What I did to fix mine was sandwich the part between 2 pieces of yupo cover stock (plastic paper) and glue it together including the little round bit from the screw holes. Then trim them up using a craft knife and redrill the holes when the glue was dry. It's worked well enough for me to use it for pinhole, which is what I want to use it for, and it can focus in and out too but I wont go there now. So there you have it, plastic fantastic.

Steven Tribe
13-Sep-2017, 03:39
I think the delay from Grimes is due to be there being no quick fix using the existing material/design. The whole unit needs to be remanufactured.

rfesk
13-Sep-2017, 16:42
My Travelwide is not broken but I am careful.

Since mine isn't broken I don't have the part to look at. But, looking at the photo it seems that it is simply a flat piece of plastic. If that is the case it seems that a duplicate made from a sheet of brass of the appropriate thickness would not be too difficult to make.

Gary Deal
14-Sep-2017, 01:02
well, yeah. When considering if/how I'm going to make a part the thickness of the material required is kind of important. How many to make also has a bearing on how it should be made - would I need to make three or a hundred?

Someone mentioned something about having a dxf file from somewhere, if someone has a small cnc mill and some experience getting from a dxf to the mill this should be fairly simple. Unfortunately, life hasn't panned out in a way for me to have such a mill, but I do have a couple of manufacturing options.

So, assuming that they can't be easily replaced through the manufacturer,

- Is this a common problem?

- How thick are those, and do they need to be that thickness in order to work properly? Would a thinner part do the job?

Drew Bedo
14-Sep-2017, 05:59
I need at least one part, but would commit to two depending on cost.

The early adopters got into the TW for $99. The follow-on buyers got in for $150. The camera cost me something <$200 (don't remember exactly) with shipping from someone who had bought two. This is not a premium/rare/collectable item so a sky-high custom part won't work for me.

But I do want to fix mine if possible.

Gary Deal
17-Sep-2017, 07:16
I understand. I have a pm off to the guy that said he had a dxf file, but no response yet.

I was able to get replacements of the broken pieces by leaving a comment in the Travelwide Kickstarter page. Not sure if that way is working anymore?

is possible with my machines.

If it is possible to redesign and to improve this parts given by the space inside of the camera, I could create some improved parts, probably out of aluminium, if SK Grimes doesn't jump in again, some day..

No files needed, I have to move the wheels and knobs of my machines by hand and by brain, but I need one complete system (TW body, helicoil or whatever is screwed in front of the body, broken parts inside of the body, screws) to have a look on the possibilities.
It will take two days to present a solution, or to give up :-)

Drew Bedo

Well, I need the fix. How many others also need this repair? Can we do a group buy?

And most importantly .. .what will it cost ?

plaubel
19-Oct-2017, 01:14
Drew,
first I get some pictures from inner side of the TW, and some dimensions from measuring.
Next I get a complete camera and i will create some sets of these dubious parts out of aluminium.
I am now planning to create 20 sets of two parts.

You didn't have to order; I can see the need, and I will do the job.

I let you know when the camera arrives.
I want to start machining the parts within one week, and you can follow the whole process - I am planning to bring some pics to this thread.

Since nobody was aible to help the TW owners, my mainly interest is helping out, so costs of manpower will be as low as possible, obviously with a tendency to less or nearly zero.

Unfortunately the shipping costs for sending the camera straight over the ocean, forwards and backwards, isn't an attractive factor.
But what the hell.

We only have to split, to devide the shipping costs - everybody has to take part in giving back the shipping costs to the member which will send me his camera.
If this costs with insurance included would have, let's say 140$, deviding through 20 would mean seven dollar to each person.

In spite of adding costs of needed material plus shipping costs, we will arrive at costs you are willing to pay for.

This member and me, we spoke about some possibilities.
Our idea is holding flat the shipping costs in general.

I one case I would send back the complete parts together with the camera. .
He then would send the parts within USA, special thanks for this.

If it would be more attractive to send the ordered parts directly, I will send directly.
Probably this is more an alternative to european members.

Drew Bedo
21-Oct-2017, 06:53
Even though I shoot LF I am not much of a high flyer these days. Before I jump into an international commitment, I have to know what the details are. I need this fix, but cannot commit without knowing what is involved.

plaubel
22-Oct-2017, 01:21
As said before, no commitment is necessary.

I just need this camera to tell about details.
From private discussion with the camera owner there seem to be some other relevant details.
Concerning the dimensions of new parts, how many space is given between back lens cell and camera body.
What's about focusing movements, are they involved, do they give trouble.
If there is less space, does simply copying the parts give enough rigidity.

In other words, which alternatives are given to improve the broken parts.

I'll let you know.

Hi folks,

My camera is now in Ritchie's hands in Germany. I sent him my TW hoping he might come up with a good solution for all of us. While initially it seemed like an imperfect solution to send my camera overseas, since I am able to distribute replacement parts over here cheaply I hope it will work out to benefit us all.

plaubel
27-Oct-2017, 16:19
Bryan, thanks for shipping your camera.

The TW herself looks and feels fine, but I immediatley understood the grande malheur in Drew's photo case.

The given place for screwing anything is nearly zero, the parts must break some day for sure.

My initially thoughts about improving couldn't be realised without drilling the camera body, but we can't drill everybodys TW.

I probably have to work with this tiny nuts instead, which seem to be melted into the inner side of the body , and I have to find a solution to get half a millimeter plus.
Really, it's a thing of half to one millimeters here.
I have another "first" idea, but instead of telling tales I want to try out first.

From today's night I am on a short trip to Hamburg, so Monday should be a good day to start with some measurements and with first lathe works.

Best,
Ritchie

I also broke the collar on my travelwide - helicord too stiff no matter what the weather.
I stuck on a Mamiya (127mm) helicord from a Polaroid 600SE camera and then added a Fujinon-w 125mm lens.
The helicord fitted very well and it was glued on permanently with epoxy.
Focus and depth of field is close enough for my purposes.
The glue needs to be sanded down and made a little tidier but otherwise a very usable camera.

If your camera had been “cost effective” it, and all the others, wouldn’t have this defect. You would have to look for a properly designed and engineered model to find a cost effective one.

I have to agree. I was an enthusiastic supporter of the 'makers' and went to their factory for early distribution.

As soon as I got it, I disassembled the biggest flaw. I realized many would break, if not ALL over time.

So I am very gentle with mine and use a very lightweight lens, Wollensak WA 3-1/2" f6.8 in Rapax.

I don't use it a lot, but just now it was the only camera I could reach without getting out of my chair.

Few Travelwide will survive decades. It was the cheapest new 4X5. So we bought it.

I doubt any would break if solely used as a pinhole camera.

That is what mine ended up as. Ultra light weight but since I had enlarged the hole in the 65mm plate for a M42 mount helical I couldn't use their included pinhole so I jury rigged my own. The helical had a too narrow opening to field the full light cone from the 90 Angulon and it wound up in another project. I've retextured the plastic GG and it has served me well on other u-build projects. Removed the fussy to load metal spring back and use my own design. Looks cobbled up but works great and is secure and easy to flip and change film holders.
So, all in all, I've used many of the parts that came with it. Unlike yours mine had hard focusing right from the start and finally became unusable.

plaubel

From the view of a company like SK Grimes, they are totally right and I didn't expect others.
The main problem for repairing is not the task herself. It's the base, the camera body, who makes things difficult.
The given space for trying to make something better than original is approx. zero.
On the other hand, doing the same like the "engineer" of this camera would be worthless.


At the end of this week I probably present my solution.

I tend to cover the original parts with cone aluminium parts to get half a millimeter to one millimeter more space for the screw borings.
After doing the repair, the weakest area then will be the original nuts of the camera, but we didn't hear about any problems with this area, and my solution will not change anything there.
If not overtightened by the customer, this seems to work fine then.

Thanks, Robert.

Today I rounded some "layaround"-metal with my Boley 4L; I wanted to find out how many space is given between camera body(inside) and the later new part.
Measuring only gave me no parameters for sure.

Unfortunately there is absolutely no useful space.
Here's a tiny nut melted to the body (inside), with a thread of around 1mm:

plaubel
5-Dec-2017, 15:18
The TW guys wided the body a bit, for giving space to the Mickeymouse ears of the broken part:
172645

Here you can see the body with my metal ring inside;
172646

Crazy.
No space.
Body with original part:
172647

Body, metal ring, original part:
172648

My initially idea, either to cover both the broken parts with an aluminium ring, or to build a bigger sized aluminium ring, will not work.

The last thing what I wanted to do is simply copying the original part ( and having way more difficulties and time issues in doing the job), but I haven't other ideas at this moment.
The given situation is everything but perfect :-)

So I prepared my mill for tomorrows making a copy out of aluminium.
This way I will get an idea if the copy would be good enough for longtime-fixing the helicoil of the TW.
See you,
Ritchie

6-Dec-2017, 01:54
Thanks for the illustrations. It makes the dificulty of doing a repair/improvement very clear!

plaubel
6-Dec-2017, 02:15
I would drill new holes to my own TW body, or milling the body a bit wider - one millimeter each side would be useful.
But this is no solution for an "easy-install"-repair kit.

Fortunately, the original srews are tiny, and they don't require much force for fixing the helicoil, so a copy of aluminium should work fine.
But as a mechanic, this "wrong way"-solution doesn't feel good to me.
But who cares about my feelings while shooting with the TW :-)

7-Dec-2017, 06:35
If this is a flat piece (could be made out of plate) and you have a dxf file, then why not ask someone with a lasercutter or waterjet cutter? Could be a cheap and fast way to have small batch made. Certainly if the holes are the same size or larger than the thickness. If you go metal then maybe it could be made thinner to arrive at that condition. Then inox might even be the cheapest option. (steel is cheaper but will need work or it rusts)

plaubel
7-Dec-2017, 08:27
Creating a dsx.file for making a little series requires wellknown dimensions.
This plastic pieces are somehow wobbling, the holes are broken.
Measuring became hard and unprecise.
For this task and concerning the tiny dimensions of the holes lasercuttung would not be my first idea.

Havoc
7-Dec-2017, 13:38
OK, no problem. I don't have a travelwide so it is hard to have an idea how large the pieces are from a photo without references. But I regulary have steel parts laser cut for hobby use and this is surprisingly affordable IF you can find a willing supplier.

If the holes are so fine (from what I understand about 1mm) then "wire cutting" would be a good way to make them. Not as cheap as laser cutting but still affordable. Try to find a toolmaker, someone that makes injection dies for plastic or so. Sadly I don't have relations in that world anymore.

But I think that waterjet cutting might be possible. If you have a .dxf, send it on (PM) I could ask my supplier. If you have a sketch with dimensions then I can make a .dxf if needed.

Randy Moe

Do we have a count on how many want a repair?

Perhaps a Poll?

Bob Salomon
7-Dec-2017, 14:33
A better question would be how many were produced and how many need repair?

Steve Goldstein
7-Dec-2017, 15:40
There were 1026 backers, so the total number of cameras produced was around this. Of these, it looks like 237 were shipped in the 65mm fixed-focus configuration, so that means around 800 cameras have the focusing helicoid. I think it's safe to say that all of the 90mm versions need (or will eventually need) repair.

Another interesting question is how many of these are being used. Mine isn't - it needs this repair :(

Drew Bedo

I need a fix for my TravelWide.

The total production was something like 2,500 I think. Maybe only 2K, don't remember exactly.

Don't know the nuts and bolts of this stuff, but I understood that commercial shops can now make parts in metals like Aluminum, Brass and Stainless Steel. Could the parts can be prototyped in plastic, then done in in metal?


I have been away a bit. Read the last two pages and I am not sure that I understand: Will the machined ring approach work? Or is the 3D printed method the way to go?

plaubel
11-Dec-2017, 09:15
Drew, the machined ring will work fine.
If you have time to wait two or three days, I should be over the mountain and being able to present the result.
A printed method only would repeat your problems, we really need more rigid stuff.

Hi Drew, and everyone else who is looking for a repair - I have some GOOD NEWS!

plaubel has been working on this slow and sure and as of now he has a working template. I am under the understanding that the part will be replicated using CAD and laser-cutting. Thanks for your patience with this - hopefully the replacement part will be available in the next couple of months.

Good News indeed!

MONTHS? Well OK.

Patience is a virtue. Yet a wise man once said, "Virtue is its own revenge." But I think he was talking about Las Vegas.

I probably shouldn't have given any time prediction. It's really out of my hands, and when the part is done it'll need to be shipped overseas to me and then out to those wanting it here in the states. It's coming together though, and that's the important part I wished to convey.

Sure . . .I was trying to be funny.

I am hoping to us my TravelWide mounted to a telescope mounting both to a rail and linked with some adaptation of a T-mount tube. The helical will only be used to adjust the distance for linking the two units so ease of operation is not critical.

Hoping to get that stacked telephoto perspective seen in smaller formats.

Drew an admirable goal.

However, you will be suspending the entire TW body directly on the broken parts. No fix will last long in this usage. Perhaps you like the low mass of the TW but inserting film holders will never be gentle.

Good luck.

I need a telescope soon as I finally live where there are visible stars.

Thanks for the on-point observation.

However the plan is to support and align both the TW and a Celestron C-90 from below on an Arca-Swiss compatible rail. The T-Mount and tube is merely fo align and connect the optical components while excluding light. Image formation at the film plane will be through direct eyepiece projection or by optically coupling the 'scope through the TWs mounted 90mm lens. Exposure will be controlled with a molunted leaf shutter or with a lens cap . . .depending on what is possible. Apature will be fixed at something very small and will be be determined through testing.

I did something like this many years ago with a Speed Graphic beater and a B&L zoom spotting scope. Results wewre interesting (big sun rising behind a windmill), but the rig was cumbersome to use

I Have some of the bits already. The damaged lens mount put this whole project on a back burner.

Now I understand your desire to get this project back on track.

We look forward to your results.

I am curious Drew, the C90 focal length is 1250mm working at f13.9 but will it cover 4X5? I would think the image circle would be too small.

Ah ha! I read your post more carefully. Eyepiece projection, got it.
Last August solar eclipse I was not in the path of totality and I used the same method, eyepiece projection with an old 60mm refractor, the telescope FL is 700mm and I used a 15mm eyepiece to project about a 3.5inch diameter image. This allowed myself and the neighbors to view the eclipse safely.

I haven't had all the parts out of the Pelican for nearly a year , and I forget things, but it is an older/original model with an orange tube and taking the 1.25" eyepieces. The formulation, focal length and eyepiece specs have changed several times over the years. Bought it used at the now closed Camera Co-Op here in Houston. Came with a bunch of accessories in a beat up hexagonal plastic case for right at $100. If this works out I may think about a better optic for the front . . ."better" meaning newer unscratched newly silvered and iin-warranty. Doesn't have to be a mirror optic.

All hinges on getting the TravelWide fixed for something under $50. Which brings this thread back to the subject of the OP.

I would think that CAD and 3D printing could be an option. I understand that commercial shops can do small parts in brass, aluminum or stainless steel now.

I may be interested in purchasing the part even though my Travelwide works fine. A metal part would be far stronger and of course a great "spare" to have on hand.

I could ask if it is possible and how much it would cost to cut such a part in the metall laser cutter at work.
Does anyone have a CAD file or a picture with some basic dimensions so I can make my own?
How many would be interested and around what price?

I will try to attach an image with millimeter scale to this post.

Does that help?

That's literally what's being done by another user, please see my posts above. I have spent the money to send the entire camera to him so as to get dimensions and fabricate parts, and we will be shipping a batch to the US for sale to recoup the shipping costs and his time.

Corran: Thanks for taking the risk to move this project forward.

I am definatly interested in getting two replacement parts for my camera.

I'm sure a lot of folks are watching for availability and prices to be announced.

Mine is still working but I will happily pay for one of these parts to ensure it keeps on working. I will flag this thread to stay aware of any progress.

Me too, so long as the price is affordable.

So, what is a proper price for a man’s time, talent, materials and tools?

David Karp
27-Jan-2018, 22:22
Bob, the price may be fair, but if I can't afford it, I won't buy the part.

What is the price?
I can't find it on yhe last pages.

Corran
28-Jan-2018, 00:21
No price yet. When there is a definite part that can be sold there will be a posting! Here and in the Classifieds area. All I can ask for is patience. This is not being done by a pro fabrication shop (and that didn't work out, per earlier in this thread from SKG), so hard timelines/estimates are not going to be given or adhered to. If for some reason it can't be done I will also post that, but it seems we are in the homestretch. Until I have solid info otherwise I cannot say anything else.

I'm having some things laser cut at work tomorrow so if someone have a CAD-file or some measurements so I can make my own I could ask them to cut some to try out.
I don't have my TravelWide so I can't measure it myself

Bryan, put me on your list of prospective purchasers. Mine is not broken but I also don't want it to be.

Thanks Rick. Yes, I hope everyone will continue to have patience (though I would say that historically TW folks haven't been as patient as they should've been...).

There has been some small issues and I am continuing to correspond with Ritchie in this endeavor. Hopefully we can all get something soon. I would like to remind all of you that I sent my camera to the other side of the world (at my cost!) and have not had it to use for months, and it wasn't even really broken.
