I used to have a cheap Delta floor model drill press but it took up more floor space than it was worth.
So, I bought a cheap Delta bench top drill press to replace it.
It's a 1/4 horse, made in Taiwan, with a No-Name chuck, and it was made in 1990.
For most of its life it lived with a jig table on it that was for drilling Euro-hinge holes. It was accurate enough for that and gave good service.
Now I want to do some drilling that needs to be a bit more accurately done.
I chucked up a new 25/64" twist bit and squared the table up to it, using a Starrett 3" Engineer's Square that I use for setup work.
Then I checked the concentricity of the No-Name chuck, using a Starrett Dial Indicator and Magnetic Base.
It started out at .003 and the best that I could get out of it was .002, by smacking things around a little bit.
Then I set the Dial Indicator up to check the runout on the bit. I set the tip to run on the plain part of the shaft, just above where the flutes started, about 1" down from the jaws of the No-Name chuck.
The best I could get out of it was .003.
Question: Is it worth buying a piece of drill rod to set this Cheap Thing up, or can I assume (or live with) the accuracy of the drill bit's shaft? (Assumption: Said drill rod is < $15.00)
Question 2: Can I reasonably expect accuracy greater than .002 out of this Cheap Thing - or am I dreaming? (I might already be in tall cotton and just don't know it)
Caveat: No way I'm buying a good chuck for this Cheap Thing. That would be even crazier than most things that I do.
Caveat 2: The holes that I want to drill will be made with a #44 bit and will only be 1" deep, into mild pine.
Caveat 3: I don't want to dismount the No-Name chuck on this Cheap Thing - for that way madness lies.
