Heya Gunner, good to see ya, mate! Hope everything is well in Gunnerville.
Thanks for the suggestion, but I just don't have the precision with a hand
motor to get anywhere near straight. I have seen the little holders for
hand motors, but I don't know how precise I could be with one of those.

While you could perhaps(not likely) drill them with a 1/4hp drill
press..you will have to work very slowly, and probably increasingly
bigger holes first.

Okay, now that brings up a question I have. If you had an adequately rated
drill press, and needed to drill a number of one inch diameter holes in 1/8"
mild steel, would you use a hole saw or a twist bit? What would you
consider to be the minimum horsepower for either type of bit?

Also, would you consider a S/D bit suitable for a one inch hole if your
chuck was only 1/2"?

Thanks Gunner,

Jon

Id consider a 1/3hp drill press to be the minimum with a drill bit and
perhaps a 1/4 hp a minimum with a hole saw. If as everyone suggested,
you gear it down and use lots of oil G

How many holes do you actually need to drill? Up to say..15 or so..if
you took your time and used oil and didnt try to force em....Id say you
would be ok with a 1" hole saw. A good quality one like a Lenox. The
other option is to use a unibit/step drill of some sort..and take your
time. 1/4 hp..really isnt very much for a largish cutter of any sort.
