  • Mag Drill Based Drill Presses

    While magnetic drills have many great uses, they are held back by their limited throat depth. I overcame this problem for my mag drills by fabricating drill press stands for them. I used 50 lb. bases from Walker Turner 15" drill presses, tilting tables from Delta DP200s , and 2 3/4" OD - 1/4" wall DOM (drawn over mandrel) steel columns 48" long. Other than the columns, all parts were purchased on eBay.

    One mag drill has power down/up feed, and the other has variable speed with reversing. Both have two speed gearboxes and a 2" annular cutter capacity. I put these together before I bought my Bridgeport mill, but still use them extensively. They can be quickly lifted off the stands for use elsewhere.

    How did you true up the base the mag drill sits on after you welded it to the column?

      Only issue is that they are damn noisy!

        I agree with the noise issue. I've never used one that was even close to being reasonably quiet. But it's a cheap and dirty way to multi purpose a mag base drill. Well done Tmate, what else you got in your bag of tricks?

          They are within a degree or so of being perfectly perpendicular to the table, which is fine for my purposes.

          Another point: Because there are two of them, I can adjust both tables to the same height and drill the ends of long stock that can't easily be held in a single vise.

            A degree out of square is HUGE in metalworking.

              Good point -- that didn't sound right. Just checked them, one is out 1/10 of one degree and the other is dead on. My Walker Turner drill press (pictured) flexes 2/10 of a degree when drilling a 1/2" hole in steel. Hard to say how much today's Chinese drill presses flex. If I want to rule out any flexing or inaccuracy I can always use the mill.

                I’d have welded a plate on the end of the vertical tube and tapped the thick plate for bolts so you could easily shim it to perfect tram.
