Subject: Re: [Homebrew_PCBs] Re: Drilling machine idea HF drill press

Ahaa, great idea. Do you get any vibration from the loose tolerance drill chuck? I'm thinking it self aligns to the flange bearing so you don't, but not sure. I will need to build one of these.

Thanks
Ron

very simple scketch in the photos section.

this mod can be done by anyone with hand tools. the key is only to
line up the shaft.

a flange bearing can be had for about $10.00 an will self align and
is hardened. that means that all one has to do is bolt it aligned as
well as possible under the axis of the drill column.

If one were to make the column collar with an angle as shown, then
the top plate can be removed for other work.
