Drilling a jewelers block
I got one of these.
Amazon.com: SE JT34443SB Steel Bench Block, 4" x 3/4" x 4": Home Improvement
I'd like to use it to tap pins out of a razor i'm working on but it doesn't have any holes in it.
There was a thread i saw where someone was explaining exactly what size and depth holes to drill in one of these for pinning and unpinning but I cant find that darn thread..
I figure for unpinning, the hole just has to be over 1/16 but i remember seeing a very specific size and depth for the pinning process.
I'm going to buy some cobalt bits tomorrow at the Depot and i'm wondering 1. which size to get and 2. what size hole sizes should i drill in the jewelers block, and even where if there is a strategic location.
Any help is appreciated, as always.
