Are the rivits for the body to frame mounts and the brake quadrant set hot or cold?
I always set them hot. Others may not.

Set 'em hot
POR 15 on the frame didn't even get burned all the way off with the torch on the rivet shank!
It's best done as a two-man job. One to apply the heat, and the other to swing the hammer.
OK, i will heat them, i have the air tool to form them. Thanks for the help.
The idea is that as the rivet cools, it contracts, making it even tighter.
Squashing the hot rivet also widens it to fill the hole.
Steve, I think you should find someone else to hold the torch next time... looks like that fella burned all the hair off the top of your head!
LOL Derek, that's good.
Yup, that one was funny
I buy my rivets from Jim Dix www.bigflatsrivet.com/contact.php
very quick delivery and he has a DVD showing how to install Model T frame rivets. Definitely hot.
Gavin - are there no suppliers of T type rivets in New Zealand?
No, there used to be rivets in every hardware store, Now you would be lucky to find pop-rivets. Not even engineering places can get rivets here anymore.
Well we got it done and only screwed up two but they are tight just not very pretty, not hot enough and not enough air pressure, heated the rest until they were ready to melt and put the gun to them with 140 psi and they were done and looked great, no pictures as the frame is at a friends house for now, we also boxed a section of the frame to keep it from bending.
Derek: I stopped and visited with Steve May(2 years ago) and he had been working on his roof of his house, and up that high in the sky it would have been the wind that blew some of it off. As you know Kansas is a windy state, being a bit flat in some area. However it is a bit of rolling hills in Steve's area. Also you might ask him about losing a tire in a wheat field!
not that I know of. I do come across the odd jar of rivets at swap meets ( and mostly do buy them) but Jim has a large range and knows exactly what rivets are required for each T application.
He is easy to deal with and quick to deliver.
For some applications there are fake rivets that are threaded bolts with a rivet head they are ok for some applications.
Rick Goelz, it's a bit late now, but I highly recommend NOT boxing a "section" of the frame, either do all of it, or none. By just boxing a section of the frame, you basically have made that portion a box tube that will not flex, it is rigid. The rest of the frame is free to flex as was intended, which will eventually cause cracks to start at the ends of the boxed portion. It may take quite some time, but it will happen. I have seen this many, many times on truck frames that have been lengthened or shortened. JMHO from many years in the welding business. Dave
David, thanks but i don't think we will have a problem as the unit we are building is a popcorn truck and probably won't be driven 200 miles per year, it is just something to do, i am 74 and will let the next guy worry about fixing or changing the frame.
