[HBR] THanks for Offers of Parts and Opinions

[Shoppa, Tim]

I would add my two cents:

1. I personally like nibblers to help with anything except a circular hole.

2. Step drills work very nicely on sheet metal. Specifically the "Unibit" brand ones are very fine tools. (I am less than impressed by the Harbor Freight knockoffs.) Drilling anything larger than about 1/4" in sheet metal with a "regular" spiral woodworking or metalworking drill bit is often unwise.

3. Hole saws can be productively on sheet metal but require some care.

4. Greenlee is the preferred brand of chassis punch but only slightly less fine, are the imports (?Deltron? brand?) in the Mouser catalog. Again, the Harbor Freight stuff is junk.
