riveting
as I said,I am a millwright by trade.I work in a large sawmill here in BC.We get rivets from a company called CAN AM chain.The HD 78 and H78 rivets are pretty close to carrier size.Any spots I want to be permanent(ie: frontal armor)I will put the factory rivet head on the outside of the machine and block the rivet so it wont move.I may try a little tack with 7018 3/32 welding rod on the inside to keep it from moving out.A piece of hardened shaft turned concave on the one end should get a reasonable rounded rivet head profile .the rivet must be heated up very hot with an oxy/acetylene torch before hammering. I use a 2 and a half pound ball peen hammer(millwrights favourite tool!) its best if done in one heat.Bear in mind this is all 'future' for me right now.Next year.If you have never done any hot riveting be prepared to scrap about the first 20 or so until you get results your happy with.the H 78 and HD 78 rivets are about 3 inches long but I can get them real cheap, and cut then to length.you should see the steel my mill throws away!!!! I can get tons of plate for nada.
