I decided to go one-stop shopping for my tools. I could have bought the dimpler and squeezer separately. The joke is on me because I still had to buy other things. But that is going to happen no matter what. I sometimes wish I had a 2X rivet gun instead of a 3X because I turn the 3X down so low for #3 rivets and rarely turn it above 2 (it goes up to 6). But that's not an impediment. A higher-quality (Sioux or equivalent) drill would be nice. The one Isham gives you has less controllability over slow speed, it's almost an on-or-off proposition. And the backrivet set I got from Isham could have used a stronger spring and a narrower sidewall on the business end, so I bought another one of those. But ultimately, the tools I have are good and there aren't really any that I dislike. And they are a pretty complete set for the plane I am building. Most of the additional tools I have bought have been reamers (.311 and .375 sizes), a #20 drill bit, a tight-fit drill kit to remove my control column mounting brackets and replace the bearings, a super expensive Unibit to drill the brake fittings through the firewall (RV-14 taildragger only), and bucking bars.
