I will be using it soon...

Any other solution is way too expensive and may NOT work with welding

I built this custom Makiflex board a while ago, adding a recessed Durst enlarger plate, to slightly recess my 150mm F9 Apo Ronar. This is an absolute gem of lens! I decided to move my lens to a Sinar Norma board, so I have it handy to use on my Sinar Norma copy stand. A couple of years ago another 150mm F9 Apo Ronar came along, for like $30 but with no retaining ring. I searched high and low but no luck, this is a very tiny rather rare ring. So last week I mixed up some JB Weld metal epoxy, and neatly glued the Apo Ronar to the Durst recessed part of the board. Finished with flat black paint and it is ready to use on my Makiflexes. Looks pretty good, eh? :)

Hoooray for JB Weld

Guys, Gorilla Glue epoxy is even stronger than J-B Weld. It costs more $$ but IMHO it's worth it.

JB Weld is great stuff. A friend bought a BMW about 20 years ago that was missing a blade on the fan. So he replaced the blade with one he made from cardboard and JB Weld. I saw him yesterday… still driving the car with that crazy fan blade.

This is a repair to the light baffle hinge on my Weston Master light meter that I did about 10 years ago with JB Weld "Kwik Steel". I removed the baffle from the meter and made a "form" with cellophane tape. After the JB Weld cured, I removed the tape and filed and sanded the surface smooth. The repair has withstood the spring pressure on the hinge just fine.

I had an excess pile of Imagon parts not matching. I cobbled this together with JBWeld. Could be a 200mm cell group not really sure. But it is sure sweet on the Makiflexes. Extension tubes China Ebay, a good well made extendable system. This is perfect to use on the Makis.

I need to get out and do some location test images with the B&L Super Cinephor 159mm F2 Cinema Projection Lens. Great fun on the standard Makiflex. Won't fit inside the Makiflex Automatic, the lens is huge and pushing the envelope on this camera. I attached the board to the lens with a copious amount of J&B Weld metal epoxy. Worked great. Hooray for JB Weld, no other way to mount this lens. Touched up the back with black flat Krylon and good to go. BTW this lens weighs north of ten pounds.

[Daniel Unkefer]

It's really useful for filling holes in Sinar Norma lensboards. I stick blue masking tape over the hole from the front, then fill with JB Weld from the back. When dry after 24 hours, I use a single edge razor blade to "plane" off the excess JB Weld on the back. Sometimes I need to re-do it, but it works great for me. I've had olde Norma boards with twelve or fifteen small holes, when I'm done, and after painting both sides, you can hardly see where it's been recovered. I don't think I could stand to be without my JB Weld. Not for everybody I guess.

If you look carefully, you can see where I have filled in dozens of small holes with JB Weld. This bunch of lenses needs final touch-ups with flat black Krylon applied with a tiny brush. Kinds like doing auto body work on a car. And making something useful from what others might throw away. These are some of my matching lens pairs, for my TLR 4x5 and 5x7 Sinar Norma cameras.

Can you spot which lens boards had holes that I have filled with JB Weld and painted?

In aero-space industry, we always used a premixed, frozen version of 2216. Probably the same thing. I think it is the same thing they use to stick the reflective bums to the highway. The keys is a good mixing, clean surfaces, and a warm curing. Also, realize its limitations.

Another story. One of my 20-ish jobs was in a store with a huge inventory of exotic bolts, taps, dies, machine tools etc catering to auto dealerships. One day a mechanic arrived with a weird-looking Whitworth bolt which had snapped, with an enormous hex head to it, which he said was the flywheel bolt to an MG sports car. When we told him we didn't have it, he asked where he could get one. We replied, maybe in England. He was panicked because he had a potential buyer coming to see the car in a few days. I handed him some JB Weld, and said it might hold it together for another six months, then forgot all about the incident. Then, just a little over six months later, some young guy showed up with a big broken hex screw with some dried guck where it had broken. I examined it, Hmmm. .. Looks like a flywheel bolt to an MG to me. He stared back, Wow, you really know about cars, don't you? I replied, I sure do. Where can I find one of these?, he asked. I answered back, maybe England. Now what am I going to do?, he asked. I looked at him and replied, I think I have an idea, and brought him a package of JB Weld.

[Tin Can]

Very bad

A loose flywheel can kill and I know people who were killed Dyno Testing

If fact Cummins warned about a certain model was prone to it

I have decided to make this part rather than glue it with JB Weld

It is a very rare camera

Show and Tell after it is fixed

Here is an extensive test and review of epoxy compounds which also rates Devcon and Marine Tex.
https://www.youtube.com/watch?v=YYnCoGEHRXw

I have used both Marine Tex and JB Weld to bed accurized rifles and photo equipment. Some gunsmiths claim that JB Weld contains steel, so before I used it on electronic circuits, I tested it with a very sensitive Ohm meter and found it non-conductive. It is perfectly suited for electrical/electronic use. The Gray Marine Tex is excellent and easy to work with but is expensive and requires careful mixing. White Marine Tex is nowhere near as strong. Here is an M21 clone bedded with Marine Tex.

There are a number of JB Weld products, as you seem to already know. JB Weld SteelStik(tm) contains steel for use on exhaust systems and the like. I believe that is the only one, but could be wrong.

[Tin Can]

Good to know

I have been looking at many youtubes

My problen is old sandcast Alu, very thin

I have new mill aluminum coming, it will be stronger, and only incorrect to we maniacs

Getting the camera functional is job 1

Watched a lot of Alu welders on youtube, they work very fast

I have done a lot of MIG, Stick and Gas, but never Alu

The other day I bought this Mamiya TLR original Paramender, from Gary himself at World of Photography. I really like his new store, it has a very funky vibe, and it's loaded to the gills. Took this unit home, and darnit, the metal is super loose and floppy, but the original screws are stii there! Examined it carefully and JBWeld to the rescue AGAIN. I pried the rail up, so I could smooth JBWeld with the flat end of a toothpick, smearing on a thick coat. Took both screws out of the rail, they are completely stripped out, smeared JB Weld on the threads thickly, then jammed the screws in and make sure I have a good hold. Wrapped both ends of the rail tightly, using blue masking tape. 24 hours later, it's good as new and works smoothly. In camera stores, we used to say this was "huffed". But now fixed and these are going over a hundred bucks on Ebay. Actually I like the patina, This will work great with my fave C2 Mamiyaflex, I also have a much cleaner Paramender to go on my C22's and C33's. The Paramender was stickered at $10 so a nice find.

You can do ANYTHING with JBWeld if you put on your thinking cap.

I also bought a 30mm Sony Nex Macro lens for my new to me Sony Nex 7. Works good eh? Autofocuses to 1"

[Drew Wiley]

Bad? That weren't nothin'. We dealt with 53 different auto dealerships. All but one had a crooked repair department. And certain import brands were "pre-vandalized" before the ever reached this country. The only real positive is that I got to work side by side with an older fellow who had been a NASA optical engineer, and really knew his stuff. For both of us it was just an interim job, and we soon got fed up and moved on, but ended up working together again until he retired many yeas later.

I used JB Weld "Kwik Steel" on my Weston meter. It is billed on the packaging as a steel reinforced epoxy.

[Alan Klein]

Would JB Weld work with a plastic handle on my microwave. The place on one end where it screws to the machine broke and there's no handles available to replace anymore. Do you just stick it or mold it or both?

[Tin Can]

I would use SuperGlue as it will be less messy and a spouse may like it better

I buy $3 3M Super glue from Amazon and it is One shot as it goes bad real quick after opening

Like a car in an auto body shop, Norma Lens Boards with dozens of holes in some of them, can be plugged with JBWELD and planed and cleaned, the back side dotted with flat black Krylon aerosol paint. The front of the board gets spotted with Benjamin Moore paint I had color matched with a Norma board in the store. Looks pretty good in my opinion. Schneider Norma Twin lens camera pairs shown here. From upper left: 150mm f5.6 Componons, 210mm f5.6 Componons, 240mm f5.6 Componons. From bottom left: 180mm f4.5 Xenars, 240mm f5.6 Sinar Symmars, 300mm f5.6 Componons. This gives me a full range of lenses from 150mm to 300mm with the twin lens cameras.

Here's the back side of my 150mm F9 Apo Ronar (no flange!!), glued using JBWeld to a Durst Recessed Enlarging Board, then on to a Makiflex Board. JB Weld is great for these "Frankencamera" projects.

It's only Six Dollars a package. WHY NOT TRY IT and then report? Sheesh it's useful! LOL

JB Weld is a two-part epoxy, so it will flow, similar to cold honey. It can be sanded, drilled or tapped when cured. It would be best if you completely remove the handle so it can be clamped together at the break (if broken into two parts). If part is missing, make a form with blue tape. The Kwik Steel I used is grey when cured. It will probably be harder and less brittle than the original plastic of the handle.

Unless there’s something very special about your microwave, they can be replaced at very low cost.

[Drew Wiley]

There are hundreds of kinds of epoxy. The nice thing about JB Weld is that it's medium viscosity, and you can find it almost anywhere. But I need a thicker epoxy to fix a chipped off section of a front concrete step tomorrow; so I'll use PC7. I always keep several types of epoxy on hand. Super-glues are more limited in what they can do. That optical engineer I referred to earlier told me a story how they made their own Cyanoacrylate glue at NASA before there was a commercial version. So nobody really knew what it was. They'd go to a co-worker with a little squeeze tube of it, and say, Hey, feel this new lubricant! - squirt a little on his index finger, and naturally the fellow would start rubbing his fingers together, and they'd get stuck. That apparently caused a howl of laughter while he ambled away to the nursing station for a delicate bit of razor blade work between his fingers. Our tax dollars at work. Just be glad nobody tried that stunt aboard an Apollo craft or something like that.

When I wrote “they” I meant replacing the microwave, not the handle. :)

In your case, replacing will definitely be more expensive than replacing a countertop model.

I may know exactly which handle you’re suffering. I replaced my parent’s GE microwave handle 3 times. Really bad engineering and the last replacement must have been a low-quality knock-off. Getting rid of that microwave was a blessing, even though everything worked well except the handle!

Small world, I visited the new WOP store a couple weeks back. Definitely a great experience for film camera buffs. I have an old "Billingham" branded wooden tripod that was given to me because it has a short crack on the metal (probably pop metal) piece that holds all the legs and center column. Was thinking about sanding the area down and giving JB Weld a go on it. Sound like it would be worth it.
