Rivet Removal

[Richard E. Swan]

Hello Again Murhpy Builders and Flyers:

I thought I had saved in my "tips and techniques" files the procedures for removing blind rivets, but now can't seem to find it.

I'm just about finished cleaning up the wings of the project I purchased and will soon be moving to phase 2 - replacing a couple of sheets under the cabin area. I've noticed there are a couple of the aircraft suppliers that offer "rivet removal" tools, but these are kind of pricey. Is there a "home made" method that works just as well, or am I better off going with a tool designed for this purpose?

thanks,
Richard

If you mean Avex rivets the best way I have found is to use an automatic center punch to knock the mandrel back and the carefully drill with #30 drill just until the head comes off. Then push or knock back the shank. Some applications may require backing up the backside to allow the "knockback" force to go into the mandrel / rivet shank without bending the sheet metal.
