Where do you get your epoxy from?

Yes I would also like more info on the epoxy. That is really a great way to do it, replace the crappy part with a stronger solution.

My idea for elbow joint is a bolt threaded through the arm and epoxied so it cannot spin. Theres two washers and two nuts on inside and outside of the fore arm. Between the washers i will apply grease for smooth movement.

The epoxy i usually use is from walmart but most hobby suppliers sell it.

Fiberglasssupply.com has bulk options to get great deals on materials and epoxy.

https://www.fiberglasssupply.com/Product_Catalog/Fillers/fillers.html Micro bubbles from 3m at a great deal

Epoxy for structure. clear finishes. Bonding. uv resistant ect https://www.fiberglasssupply.com/Product_Catalog/Epoxy/epoxy.html

Cheapest resin is polyester resin. good for general use with fiberglass cloth to make cheap strong parts. You pay for what you get. Epoxy is stronger. https://www.fiberglasssupply.com/Product_Catalog/Polyester_Resins/polyester_resins.html

I did simple things like sanding last night. I also glued in the shoulder pieces as well. i will pick up spray primer and start priming.pieces so i can see low areas and get the surface all uniform. I believe i am about to. Start a new thread tonight with the priming and let this thread be a reference for what has happened so far.
