This project has evolved some , the basic rundown is I'm modding two Omnibots , one a regular the other a larger 2000 model. I will have two ezb kits , rad base idea was thrown out because of so much noise but could go back on the table if the omnibot drivetrain is too weak to pull it.

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.
Heres a additive link ill try to find specifically what i have https://www.amazon.com/System-Three-Silica-Thickener-Quart/dp/B0035YGKZC/ref=sr_1_15?ie=UTF8&qid=1348095505&sr=8-15&keywords=epoxy+additive

I have a quart sized container. You added it to your epoxy mixture for lower weight. Thinner layers and higher strength. I will post a picture of my bottle tonight if i remember.
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 used something close that epoxy before,but better is aluminium,very light weight stronger then epoxy and parts easy to remove as i get my frame design you can see how its done
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.
