Fellas -
Need to replace a few roller tips on vintage (1960's) Jonsereds chainsaw bars. I drilled the old solid rivets out and I need to install the new (used) tip.
The hole that the rivet needs to fill is .161" - same as a #20 drill bit. The bar itself is about .19" wide, but the roller tip section is thicker -- the rivet, when installed, should be about .245" from end to end. The head diameter is diameter at the outside of the countersunk hole is .26". The rivets are flush mounted.
Closest I can find at McMaster-Carr is a 5/32" (.161" hole and #20 drill bit) for maximum thickness .242" which sounds good so far, but the head diameter is .29" and these are Mil-Spec aluminum instead of steel.
I'm thinking these will work, but I don't have any experience with solid rivets, so I'd appreciate any input.
Forgot to mention -- these are going on nice saws that will be sold on eBay, so I'd rather not use something that's obviously not original (domed rivets) or sloppy.
Thanks,
Scott
