Nerd Restoration Experiments
 

As an outcome of not really being able to get some body bushing I wanted in the color, material, price etc. I thought I would use some liquid urethane I've had lying around for the last 15 years.

It's about Shore 60A, maybe just a tad too soft, wrong color etc. but I just want to play around with the stuff. I cast some body cushion donuts using a piece of 1" OD pipe, and some 2" ID exhaust pipe. Done under some of the worst possible conditions as far as age of product, no degassing, no mold release (don't want silicone in my shop).

Rubber repop donut shown also.

Anyway, results were not horrible (no I'm not going to use them). Got some damage getting them out of their metal molds. Got me thinking though, this stuff adheres tremendously to clean metal, and even smooth metal in this case. Could be used for all kinds of mounts, vibration isolators, seals etc.

Wonder if the right product was used that OEM engine mounts could be rebuilt using a product like this rather than using the POS aftermarket pieces.

Curious .... anyone else played with this stuff? I know it doesn't make a lot of economic sense, but I know there are other restorers out there that like to experiment and try to reproduce things that either aren't made, or are made very poorly. ... Kind of like my Zinc plating buddies :)

Make prototype. Refine prototype. Plate pieces before pour. Make people jealous.

That's great! Kind of amazing the 15-yr-old resin cured. No reason to think you couldn't do as well as any repro and probably better if you sorted through material properties. Good to know the urethane adhesion to metal is strong. Noted!

And that motor mount thread was awesome...

Thanks for sharing your nerd materials and fabrication stuff. Materials and process development was half my career so I enjoy all related posts.

I knew someone else probably messed with this stuff ... even the same brand I had lying around.

If I get a LOT of spare time I might try to find a used set of OEM mounts, clean them up, make a mold, burn the old rubber out, put the metal pieces in the mold, pour in some urethane and see what I end up with.

Neat idea. I've have used grey gasket maker to stiffen up failing mounts like a dogbone and a trans mount on a BMW that was outrageously priced. Worked out well.

Try,try again. You'll get it. Looks good thanks for sharing. Ingenuity. When working on old 'stuff' trying to fix,I say "cant be any more broker'.

Exactly .... when option one is .. throw it in the garbage, option two can be anything :)
