Does anyone have experience with using commercial resins like 'Bondic' instead of baking soda/CA for nut slot adjustment? Sure would be easy to use the one-part resin and a UV flashlight to set it, if it was hard enough to be useful.

Thanks!

Nope not with with Bondic but our light cured dental fillings are the same idea and work great.

Peter maybe do some tests with a dummy or spare nut nut in use and let us know? I'd be most interested in how it files because that's got to happen too.

Read my mind(?), you did. For that stuff to be usable, it's got to be dense enough and stiff enough so that it can be formed, remain stable, and stay put. I noticed in promotions the word 'flexible'. Not a word I wanted to see. For a non-professional user, materials are ideally inexpensive with a long shelf life or packaged in real small units that can be stored a long time.

The epoxy for teeth is really hard designed to hold up to chewing over 10-15 years. I looked at this product and I did not get the feeling that it's design target was being a very hard filler.

I did an informal test with Bondic. Interesting stuff, but not up to what's needed for nut slots.

There was a product that I used to use to even out dips and depressions in racing sailboat hulls and windsurfers and it was called Marine-tex that might have promise too only it's not light cured and you will have to wait a day to file it.

The light cured dental fillings come in two formulations one that is liquid and runny and the other that is like a stiff paste and can be formed to make say a new nut corner or side chip replacement, etc.
