[Towertalk] Chassis Punches, Stepped Drills

[Robin Midgett]

Chassis punches are available from Home Depot and any electrical supply 
house. Also, search using www.google.com, and I've seen them at ham fests, 
they also appear from time to time on the For Sale-Swap reflector, Homebrew 
reflector, and Amps reflector, all of which have searchable archives.

Depending on the thickness of your chassis, I'd recommend a UniBit stepped 
drill instead of the chassis punch. It is much more versatile, less 
expensive, and makes nice round holes from ~3/16" through 1" in various 
steps, depending on which model you purchase. McMaster-Carr will have them, 
grainger.com also, also at Lowe's & Home Depot. Get a can of tapping fluid 
(cutting fluid, metal specific (steel, alum, etc.)) while you're at it to 
make the stepped drill last longer.
