I was told that I should reform the heads of the new rivets to the same size and profile as the originals. So this is what I did. The sink washer allowed the rivet to spin while I removed metal from the top. The diameter was made smaller by chucking the rivet in a drill press and using a flat file.
Then I put the rivets in the gear box casting and whacked them slightly with a brass hammer to set the angle. This will help me to determine more accurately the amount to cut off before final installation.
Looks really good Mark
Yes, looks pretty much like the old ones after extracting them .. and in the column. Will install them tomorrow night with the help of a friend. Will be nice to get the steering back together even though the chances of driving it soon are pretty remote given the forecast. The steering is much improved and the only slop I feel is due to not tightening up the nut on the steering wheel.
Mark, which nut is that? The one on the wheel or the one behind the wheel??
(I had to ask!!!)
LOL: well, one has to be tight ... the other probably shouldn't be tight whilst driving. :-)
I made this shallow bucking bar last night for inserting the reformed rivets. I'll clamp in into my bench vice and lay the column on top of it.
Way to go Mark! Aren't you glad that you did it! You didn't really have to bend that rivet. It would have conformed to the correct angle when you started bucking it.
Though you would be pleased. Yeah, I know it would conform on the first whack. The only reason I did it was to accurately cut the length of the rivet so that forming the new head would be effective.
Mark, how did you form the concave cup on the end of your punch? Jim Patrick
I used a Dremel tool with a small cylinder grinding wheel. Made a slight depression in the center to begin. Then I took very shallow cuts while slowly turning the rod with my other hand.
Once the concave area was relatively even I sanded the outer part of the rod with my stationary belt sander. Then I used some wet and dry sandpaper to smooth it both outside and inside. For the inside I placed some of the abrasive paper against the concave surface and pushed against it with a spare rivet while turning.
