----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]----Norm, those small rivets are 3/32 dia., so you use a #40 bit to drill them out. The larger ones are 1/8 dia., and you should be using a #30 bit for them.

----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]----Hi,I am currently replacing the lower firewall on my Ercoupe. The larger rivets came out nicely. I drilled out the heads with a number drill (forget what size) drilled and punched out the remainder of the rivet. I am going to do the same thing with the smaller rivets on the firewall but if anyone knows the correct number size I would appreciate it. The drill is approximately.096 (3/32). I know that number drills should be used for drilling out AV rivets but I am not sure what the proper number size is.Any help would be appreciated - not expected. Probably a long shot that someone knows this off the cuff.Thanks againNorm Decou============================================================================== To leave this forum go to: http://ercoupers.com/lists.htm Search the archives on http://escribe.com/aviation/coupers-tech/
