That's it!
I can't say why he had so many of these though. I do think I saw a few of the clamps as well in one of the boxes.
He didn't have a drill press when I was there, but there was a grinder and small belt sander, and a table saw. Maybe it was something he brought home from work over the years. Its just odd that they were both in his tool box as well as a few mixed in with various bike parts boxes.
I also considered the idea that he may have been slipping mentally as he got older, we found things like screwdrivers and other tools boxed up with bike parts. I found a BB wrench in one box, a few Snap On screwdrivers in other various boxes and a Park chain breaker in a box full of calipers.
