The grade 8 button head allen heads and washers I use are superior in strength to factory rivets. The rivet hole in frame is slightly smaller than a 3/8 allen head. The allen head virtually threads itself into the frame holes. The square on frame was measured and 1/16----1/8" square was final measurementMy 35 chev standard series coupe frame containing 186 bolts was done that way in order to have the inside of the frame painted as nicely as the outside. Front kugel IFS cross member was welded in and the jag rear was cross member also was welded in.New frame that was originally under the coupe is now being used for the roadster SHAZZBOTT. Note from posted picture of my frame. that there are 12 button head allen heads on the top of the X member plate and same amount on the bottom. The front of the X member has a transmission mount using 6 more bolts that ties the front frame rails together. Also the front running board brackets tie into the trans mount, making for a very strong total connection.This 1935 design is so superior to a 34 Chevrolet standard frame as to relegate the 34 frame to a willow branchYou do your builds exactly as you see fit, I employ my own methods.mike ..............HAIRBALL
Well I'm less enthusiastic about the blaster. It was just too good to be true. I spent about 3 hours today playing with it and got a little over an hour blasting done. It's not as quick on the rust and it is on paint. My frame isn't pitted but has an even solid surface rust coat. I used 3 bags of sand and got about 1/2 done. The sand suction line had melted to the air cleaner cover on the pressure washer. Heat from the sun, spilled fuel? I had to cut several inches off. The sand line kept clogging. The slightest dampness makes clogs. If you stop and the line is not just right water runs into the sand line. Once there was a small rock in the nozzle. I figured a way to clear the clogs pretty quickly. It's not getting it as clean as it did the crossmember and there is more flash rust than I thought. Tomorrow I'll finish what I can and flip it over to get the rest. Then I can asses what I've got.
