Here are some more to add to the list.
Harbor Freight 20 ton press. After making several trips to a machine shop to have stuff pressed out I bought this. It paid for it self the first time I used it.

Harbor Freight vibratory tumbler. I got this some years back after seeing one on Jay Leno's Garage. Although this is not the same brand it does the same thing. The green pyramid things are the cutting media. It does a great job cleaning rust off of bolts and small parts. The key thing is to add a little water just enough to get everything wet. Also, you got to respect the tumbler.

If you turn your back on it and leave for a while it may explode (top comes off and parts and media everywhere). This happened to me a few times.

Photo shows before and after cleaned parts.

Harbor Freight large 1/2" drive bit set. You need to have at least two of these around. They have a lifetime warranty so if you break a bit, and you will, return it as a set for an exchange. I've gone through several sets but the do get they job done.

The next item I splurged a bit only because it is an awesome tool. MAC Tools Air Hammer Kit. This has more bang than the run of the mill air hammers out there.

The last tool for this post is a compact 90 degree electric drill by Craftsman. Again, I spent a little extra for this and it gets into some tight areas were others don't.

A side note about Craftsman tools. I just found out recently that the Craftsman brand has been sold off to Stanley, Black and Decker.
That's all for now.
