Oooppps, sorry wrong thread.... I know I've seen one. The guy had tested them up to 120 psi for burst rating.... I will dig around and find....I'm stubborn that way

Nope. That was the proper thread. The pics with the airbags being tested under pressure have been deleted. I'm going to assume that the idea never panned out....so, I stand corrected. You CAN be the first to make a functioning airbag. Lol

My idea for the air bags is to make a wood pill like shape then plastic dip it till it is right thickness. They don't need to hold alot of psi 10-20 maybe 30. Then i will cut holes at top and bottom. Then use washers and some little aluminum post. to keep it cheep and simple.

I guess the challenge will be to maintain a uniform thickness so that the bag maintains the proper shape when pressurized and not bulge or deform to one direction or other? Or probably not a issue due to scale size and the direct vertical load they would have?

Happy building , good luck and keep us posted
Pics too please
