Moisture is one thing we don't have to worry about too much in Tucson. Outside of a few weeks during Monsoon season in July/August it's pretty dry - often single digit dry.

Good question, Peter. The short (and long) answer is that I don't know. Hygroscopicity is a known issue with Polylactic acid as is relative intolerance to extended exposure to high temperatures. (I...

Thanks. I have a lot of days when this really seems to be true. I've been learning how to drive my fancy new wheelchair - must have done $1k or more damage to the walls and cabinets by now. Chair...

You won't see it until you've been a member for a month.

By the way I found some information that looks like the ECO-ABS starts to soften in the 60 - 65 C range so it should be OK for normal use - unless you live in Death Valley

The flange itself adds a lot of strength to the board. By the way, my next project is to print a back for my 5 X 7 Linhof Kardan Bi. I've lost track of my 5 x 7 to 4 x 5 reducing back so...

I would have said the same thing - but after printing a couple for under a $ each and free "overnight delivery" with offset lens holes and flange mounting holes already in place I have to say I'm...

I can check the printing price for a metal board from a service bureau, but printing one myself is overnight turnaround and maybe $1 for materials. Of course therexs the expense for the printer and...

Thanks much. I've seen that one. What I'm wondering is whether anyone has mapped the number from say 27.36 to the nearest third or half stop between f/22 and f.32.

f 27.36 isn't a particularly...

Just wondering if someone has a good conversion method to convert "New Zeiss" aperture sizes to today's standard system.

Yes, I'd give it another try using "solid" infill. I haven't been to Picacho Peak in a few of years with a camera. I should go again. Funny name Picacho = Peak in Spanish so it's "Peak Peak. On the...

Maybe we need a state by state rating of plastics for softening. It gets a bit warm in a car here as well. But I used to spend time in Miami in the Summer (Eastern Airlines if you're old enough to...

@ Andy

By the way, where in AZ - I'm in Tucson

Re mottling a couple of things occurred to me. Was it a random pattern or somewhat regular? How thick was the lens board? Usually they just lay...

I've been using printed lens stops and haven't had any issue with light leaking through the Dremel plastic - but I thought about that and will print thicker if it's a problem. I'll test the Technika...

I mostly use longish lenses so don't often need a recessed board. On the other hand maybe I need one for my 90mm Super Angulon so I can get some rise/shift - sounds like enough reason to make one:)
...

Yeah. Coming up with a strategy for positioning the build is tricky. I've had some parts break when trying to remove the generated support structure. I do sometimes find myself building sub- parts...

The Dremel 3D45. I think it might be made by Bosch. They have a good cloud software package that lets you upload your CAD filed and their software slices the object into layers and sends the files to...

Thanks Peter.

I got a Dremel 3D45. It was a little inder $2k. I actually got it to makeparts for a sensor array Ixm eorking with, but I started out making things like stirage boxes for the...

I thought I'd give it a try. There are a couple of small things I'd change for the next board, but 5 minutes with a fine file and it fits and the light trap seems to be properly aligned. Seems...

At least they're smaller than the Minnesota mosquitos that folks stuff and eat for Thanksgiving. Nice thing about living in Tucson is that there are relatively few flying insects outside of a few of...

A million years ago I was a Chem & Physics combined major. I remember one of my classmates messing up and causing the lab building to be evacuated when he "forgot" to work under the hood and got a...

Ah yes, Tenaya lake mosquitos. I still occasionally find a carcase in my camera - and it's almost 50 years since I did the Adams workshop.

Fuji Gx680 - Ilford FP4+ - D/23. 135mm Fujinon

We've had this Japanese dragon mask since we lived in Tokyo - maybe a little over 30 years ago

I think you'd get quite fine 60 x 75 prints -at 300 DPI from the IQsmart2 - it has a 4300 optical spec. The IQsmart 3 goes to 5500 optica

Come to think of it you'd probably only need 200 or so or...

Another happy Creo user here - I have the IQsmart 2 and it's excellent. Upside - great results, built like a tank, perfectly capable of running 24/7. Downside - humongous., heavy, not so cheap, and...

+1 for contacting Michael Streeter. I got my IQsmart from him and he's extremely helpful. IIRC he has a stock of Mac Min's and software.

I wonder why a cam couldn't be 3D printed. Now that I have a printer I'm starting to wonder why anything can't be printed - sort of the old "If you have a hammer everything looks like a nail." I...

Thanks - I looked at Prusa but it didn't look like the Dremel was supported. (Yet???)

I put the stops in front of a high powered LED flashlight and the 1mm plastic is light tight. There were a couple of pinholes where I tried to emboss the f-stop label 1/2mm deep but that would be...

The most recent time I talked to Carol last year she told ne that her husband was in hospice care but she was still working, although at a slower pace.

I just got a Dremel 3D45 3D printer. I really got it to make enclosures for some of the odor-sensing chips I'm working with but as a first project I made Waterhouse stops for my Darlot lens as well...

I've had my 305 Repro Claron since around 1970 - 1975. I bought it new for my Kardan Bi 5 x 7 which I bought new in 1970. I got a Linhof Symmar 210 with the camera but the Repro Claron became my main...

Yes - this house has AC AND Swamp Coolers. We decommissioned the swamp coolers because they made the place so damp.

Inside temp averages about 74 - 75 but gets close to 80 in the summer, which can...

Opposite problem here - the "cold" water can get up to almost 90 in the Summer. One "solution" has to been to use Ilford XP-2 in the summer since it's a c41 process. But that only works for MF:(
...

I saw a mention of the Kessler Crane Kwik release. I use several of them and they are superb. I have two of the bases mounted on the platform of my Majestic - some of the cameras have the QR plate...

I think the Technika board is a really good candidate. There are even adapters available to mount them on MF cameras. I use lenses in Technika boards on my Mamiya RB67 as well as my Fuji GX680. Both...

Pretty much just a matter of how much weight you want to schlep around. If you were shooting ULF or even 8 x 10 I suspect the weight differential wouldn't be that significant for your pack mules,but...

Business models are always subject to change. They were quite pleasant when I contacted them and sent me PDF's of the sold out publications I was interested, in so I'd be more inclined to think they...

Amen

I've been pretty favorably impressed by Fujinon lenses of all stripes. I use a 250mm for LF and I have a Fuji GX680 with six lenses. Just for fun I ran a series of tests comparing the Zeiss lenses on...
