    What size Greenlee punch are you guys using for Belton octal sockets?

    A standard octal used to be 1 1/8", but the Beltons are a little bit bigger than that aren't they?

    I think I used 32mm (~1 1/4"). Bit of play, but not excessive.

    I use 1 3/16” punches and they’re perfect for Beltons.

    ^^^^^ this. Doug Hoffman notes: “Mounts in a 1.18 inch chassis hole for top or bottom mounting. Can also be mounted in a .99 inch hole for bottom mounting using the small diameter section of the socket.” So 1 3/16 *is* perfect.

    And the first couple are actually even reasonably priced!

    Every time I look at those radio chassis punches on eBay I'm appalled at the prices and i just decide my set of conduit punches are close enough. A single radio punch usually costs as much as an entire pre drilled chassis, and forget buying a full set, you might as well just buy a CNC machine... :eek:
