I'm trying to determine the best method/tool for drilling 30" x 3/4" particle board on end. The holes must be as accurate as possible to align correctly with the tops and bottoms that have been pre-drilled.
My old Craftsman bench top is possible, if I rotate the motor assembly on the support post, material length is only limited to bench height. However, this thing has a belt and pulleys that make this thing usable as a mixer. I wish I was able to measure the runout.
I have a hand-held drill guide that is absolute junk. Even if my drill has no run-out, the two rail guides are the weak link. And then, I'll still have to triple up the material, to have an adequate support area for the guide.
I've determined to put my project on hold till I can increase the accuracy.
1. Does anyone know of a variable-speed bench top that is the king at having minimal spindle runout that also is able to be rotated off-center?
2. Is it possible to decrease the runout on a multi-pulley DP just by changing the belt? Of course, I'm assuming the spindle is not adding to the runout, and therefore I have not considered fixing that too.
I just can't see spending $900 on a floor model, especially when most are not var. spd., and the overall quality is sub-par.
Check out my set up. Kinda rigged, but under the circumstances, it's the best I could do.
