How "creative" have you been with epoxy?

[Farmall Cub]

I have done a few things over the years with epoxies I'm kinda proud of.
How about you?

Pro Poxy is my favorite for hillbilly engineering.
When we bought my son a BB gun years ago I also got him a red dot scope not thinking there was no way to mount it.
I roughed up the surface of the gun and made a Pro Poxy square I attached to the top. When it cured, I filed it into a dovetail mount that stayed on the gun till he grew out of it.

When I was a plumber I had a customer with an old clawfoot tub that had a very large drain and shoe that I couldn't source locally.
It leaked because the threads on the brass shoe just looked like threads. Due to age they lost all depth and wouldn't grab the drain threads.
I sanded the shoe out and lined it with Pro Poxy and coated the drain with stem grease and screwed it in making threads. I let it sit for about ten minutes and unscrewed it, Let the Poxy cure and put it together tightening it like I would a new one. Never slipped or leaked.

JB Weld has fixed small engine blocks and castings, radiator leaks, made threaded bosses for small items and modified custom air intakes, etc., etc......

JB weld is awesome I've used it on a ton of things like engine heads, boat repairs. Used it like Bondo on a friends TR6 floorboard that had some pin holes in about a six inch spot.

Ayuh,... I do alota boat repairs with epoxy,... much stronger than polyester,...

Nothing too creative but I was making serving/cheese platers out of the tops and bottoms of wine barrels and once I reglued them together there was slight gaps that needed filling. Well the inside of a red wine barrel gets stained purple so to match I sanded the surface and mixed the dust with epoxy to make some purple filler and squeezed it into the gaps with a syringe.

changing the engine in my truck I had snapped a plastic transmission bracket holding the shift mechanism on the ******. good old jb weld gobbed up around it and she's good to go

I have used JB Weld a lot on my old CJ-7 for the same reasons!

Mix it up, smear it over the pin holes, and paint it. Done!

Well I have one I'm not so proud of, but I learned the limits of epoxy. When I was a kid I used epoxy to fix a hole in a fiberglass gas tank on my dirt bike (Ossa). Took it out riding and after a while my legs were getting wet and then the bike stopped running. The epoxy was dissolving and the hole had opened up. The epoxy got drawn into the carb and gunked up the fuel bowl and passages. Was able to clean it out though.

I was a machinist for a large printing company. A large part of their business was printing checks. One of the old obsolete machines was having impression troubles making the MICR numbers readable.

The numbers are set to the customers checking account numbers, and are set on a huge rotating wheel. The numbers then impress steel powder-infused ink onto the bottom of your check. The backup cylinder that the numbers "crash" into, was worn out. Beat to death from millions of impressions, not to mention piss-poor operators who set the impression too high and beat the **** out of it for years on end.

The cylinder weighed about 600 pounds of solid hardened steel. There was no way the management would allow me to remove and put out for service - too costly... and they had a production schedule to maintain. So I came in on the weekend, and used some Devcon Titanium Epoxy putty, to fill in the low spots on the cylinder. Once cured and dressed, the faint numbers came in sharp and crisp.

I was afraid that the putty would be much softer than the steel it was adhered-to, but the operator of that machine never complained again about it so I was happy. Not only did I save the company thousands of dollars, but also saved myself a mother-effer of a job.

My niece bought me a really Kool plastic long stemmed drinking cup, with a hollow wide base, in the design of a wild skull. It was very impressive looking, but got top heavy when filled with my beverage. So, I simply turned it upside down, filled the base cavity with five ounces of lead bird shot and then poured the base full of Devcon one hour epoxy, and the skull cup never wanted to tip again. Now my drink holder looks good, and has some real heft to it.

Some family members with a pool had trouble with some of the fittings near the pool pump leaking. They were PVC, and the UV from the sun and the chlorine fumes had made them brittle. I knew if I replaced one fitting, I'd be replumbing at least every pipe above ground because they'd shatter into pieces the minute I tried to unscrew them. As a last-ditch effort, and to prevent having to close the pool down mid-summer to replace ALL of the pipes, I soaked strips of cloth in 10 minute epoxy (Devcon, I think) and wrapped the cracked sections tightly. It looked like hell-- lumpy sections of resin-impregnated bedsheet wrapped around chalky, discolored plastic pipe-- but they hung onto the house for a couple more years and the fittings never leaked again. Saved them a couple thousand dollars, since no pool company would touch it unless they could replace all of the piping in the entire system.

I tried to fix a coolant overflow tank on a Caprice with JB Weld. It had a small hairline crack in the bottom from the continuous heat and expansion/contraction cycles. I drilled both ends of the crack to stop propagation, chamfered the crack itself with a Dremel, slathered it with JB Weld (the epoxy with the highest continuous temperature rating I could find), and pulled a partial vacuum on the tank with a vacuum pump. The vacuum helped to draw the epoxy into the crack and mushroomed the end to keep it from blowing back out. It worked when I pressure tested it, but I saw hairline cracks starting in other spots, and I didn't have the nerve to trust the repaired tank on a long trip. I found a NIB tank on eBay and just replaced it.

Work with epoxy on a regular basis.

A lot of RC bits for friends. Built a few custom race sailboat rig prototypes like pulley clusters and instrumentation mounts etc. Boat and surfboard repairs amongst others.
View media item 57182
Otherwise I build kitesurfing boards for myself and working on a couple of hydrofoils at the moment.

I have a friend who worked in the composite industry, repair the rusted out panels in his truck with fibreglass. I'd have welded patch panels instead though his repair was much faster and still fine after 10 years' use.

I had the side of a gas tank rust to the point it started seeping fuel. I wiped the area down with laquer thinner and smeared the whole side of the tank with JB Weld thinking it would buy me enough time to get a new tank. I ordered a new tank, and then finally changed it 2 years later because I had already spent the money on it. I was amazed at how well the epoxy sealed the rusty steel.

I crashed a bike on the track (years ago) & broke/ground away the side cover of the motor. JBWeld plugged the hole & built up the thin areas. I used that side cover for the rest of that year. Held like a champ.

I think that between JBWeld, mechanics wire, & duct tape. One could fix just about anything.

I routinely use epoxy to fill unneeded holes in a metal panel or chassis.

Back up the reverse side with thin fiberglass sheet, overfill the hole with expoxy, sand and feather to level with the surface, primer and paint. You can not tell the hole was ever there.

In the early 70's we towed in a customer's Jeep that was "making a funny noise and then wouldn't move" Turns out the dual U joint at the transfer case end of the drive shaft had worn so badly that it was knocking into the housing of the automatic transmission. Knocked a whole corner of the housing right off, including part of the surface the pan bolted to. I don't recall what we used at the time but we formed a whole new piece out of some 2 part epoxy, using tape to keep it from sticking to the pan. Once it cured we took the tape off, used a file to flatten and smooth the pan mounting surface, loose bolted the pan on and drilled the bolt holes, tapped them and then put the whole mess back together. We told the hippy that owned it to get rid of it ASAP. 2 Years later he brought it in for something unrelated and we put it on the lift - epoxy fix was still holding!

Tecumseh intake port correction with Titanium putty. It worked well.
JB Weld for a crack in my concrete driveway. It was completely gone after the winter.

 

[killahog]

Reading this thread just reminded me I fixed a small pinhole in one of my copper waterlines at the house with JB in October. I need to go do it right now.

 

[kaymccampbell]

Used JB to rebuild the gas door hinge on my Burgman. It takes quite a beating.
I'm also starting a project to make one funky phone out if three and hoping JB will bond the plastic.

I hit a rock and caused a steady oil leak in a steel oil pan in a car years ago. I was able to jbweld a piece of plastic bag to the pan, and it dried before the oil filled the plastic and got to the jbweld and destroyed the seal. Created this weird thin bubble of motor oil filled garbage bag.
Got me about 20 miles out of the mountains, where i was able to buy a drain pan, fresh oil, and use jbweld a second time after draining to seal the pan leak. Remained that way for years

Epoxy is great stuff

I think Don Garlits once said that they used JB Weld and a piece of sheetmetal to seal a hole in the side of an engine block and ran it that way for the rest of the season. This was in his early days, when a new engine block (or a whole new engine) was financially out of the question.

 

[A**holes Garage]

I have used JB Weld to seal up some gaps on my smokers.

I recently used A&B epoxy for an underwater pool feature last summer, has held up so far.

 

[sberry]

Done all kinds of stuff with it. Even holes in pressure piping with the aid of sheetmetal screws and a patch. This block repair may have been before the advent of quick. The bottom of this was so porous it wouldn't weld at all.

Been using it for many years. Recently I had to replace the customer toilet at my business. The concrete under it is bad. I've already drilled and sunk anchors, but the concrete just falls apart.

Now, I'm installing a new toilet and didn't know what to do. I went and got some two part epoxy at the big box and set it in the hole before I reinstalled a a few more anchors. I was skeptical, AND it was still wet with water. Yesterday I checked it out and the silly toilet is still as solid as a rock. It's been kicking my **** for years. Maybe I finally won!

 

[longez]

I built this 33 years ago with epoxy - still have it and use it weekly

 

[WingZombie]

Used JB weld to hold together the cracked flywheel in a VW Bug. It held for about 8 months.
