[TheForge] HELP---Drilling A-R Plate

[Washington, Aubrey O.]

I've never tried drilling hardened steel with it, but my old fashion hand cranked post drill with down-feed will drill a 1" hole in 1" mild steel plate (with a lot of cranking and lube).  It requires 1/2" shank drill bits, and I've never seen those in carbide.  But, I have a Jacobs chuck on a 1/2" shank that I can put any twist bit into.  Maybe I'll see how it does on leaf spring.

Maybe you didnt see this link before- I posted it yesterday.

but here is a cole drill- it is essentially a manual mag drill- the
same in principle, but with no magnet.
But, as far as I know, they havent made em new in some time.
So you scan garage sales, craigslist, ebay, and antique stores.
