any advice on using a pneumatic squeezer. im having a hard time adjusting the spacing between the jaws. I squeezed about 50 practice rivets and seemed like i had it but when i got to the horn on the elevator i could not seem to get it right. just ordered a new spar and ribs for right elevator (i messed up the spar drilling out the horn ). im a newbie builder bought the Isham kit great tools but no hand squeezer but i think it might be a little easier to line up before setting the rivet.thanks in advance.![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
