Streaker,

Thanks for the post. I in fact did this on two arms of the 4 I need to fix! It works, but just barely. The old sliders had about 1/8" of stud projecting from the arm after the stud/rivit had been spread. Using your method, indeed the stud spreads to fill the hole, but it ends up almost flush with the arms sheet metal. I ended up using a center punch to try to swell the rivit out so it would roll over the arms sheetmetal and thus avoid a loosening problem some day.

My point I guess is that the part is wrong. There should be a better solution. I talked to Tom Race at RT, he advises one tack weld the stud to the arm. Not quite what I wanted to do, but perhaps good advice.

Thanks
