Jerry, et al,
I echo the email below. A GOOD drill press is a requirement. I have a Dewalt
that was a hand me down from my father, built like tank in Pittsburgh, circa
1955 and it is great! (After a thorough rebuild) But the thing that has made
it absolutely a great machine was the addition of an X-Y table I bought from
Enco for a sale price of about $100. It is not a milling machine by any
stretch but drilling tubing to make antennas is a piece of cake. It will do
small milling jobs (slotting tubing) but the quill is too small to attempt
anything bigger than using a 1/4 inch mill. Ok, enough sermon. Spend 400
to 700 bucks. Look for older machines that have a substantial amout of metal
in them. If it can be rebuilt, go for it. I guarantee the payback will
justify the expense. But then again, who knows what might be under the Xmas
tree next year?
