This drill press was pulled out of the scrap yard many years ago to salvage parts from it. The head was cracked on both sides, the table had the “grin of shame” plus many parts were missing or broken. However, I gave it to a high school student needing a project and helped him to completely restore it. First it was “de-rusted” primarily with a wire brush. The column was polished in a lathe. The cracks on either side of the head had a small hole drilled at the end of the crack to stop it from continuing. Then half inch plate steel was cut, shaped, and fitted into the hollow center section of the head on both sides. Four bolt holes were then drilled and spot faced through the casting and into the steel plate. Two bolts were added then to either side of the crack. This was done on both sides of the head. As a result the head is rock solid and the quill still parallel to the column. The “grin of shame” was filled with JB weld and the table milled flat. We decided to add a third pulley so that we could use Silver and Demming type bits and drill up to 1” holes using only a half inch shank and very slow speeds. The motor mount was missing so we fabricated a “hinged” type mount (not realizing at the time that the original was done this way as well.) The three pulleys were all found in scrap yards so they were not a “matched” set. However, making the center pulley mount to where it can slide in and out and front to back allows all speeds to be used with only two belts. If you are in the low range of the spindle belt, lifting the motor and moving the belt gives you three speeds. However, sometimes the motor belt needs to go “below” the spindle belt and you have to loosen the handle, slide the center pulley to the column, change belts, slide it back, and then lock it down. Takes less than a minute either way. The center pulley system consisted of a 3/4” pipe coupling bored on each end to accept ball bearings. A shaft was then made to fit the bearings (with snap ring retainers) and the pulley. This bearing system was then attached to the slotted arm with two set screws after boring the end of the arm to hold the coupling. The drive system with multiple ball bearings was the most complicated. We had to measure openings, find bearings with proper ODs, then design the drive with female spline around the particular bearing’s IDs. It was a complicated part, but the 15 year old student, Bryan, nailed it. The drawing at the end shows the red shaft he had to machine holding some 10 thousandths tolerances for the bearings. The motor has an inline plug to the switch box allowing the motor to be unplugged for any service needed. One set screw also allows it to come off the motor mount shaft. The switch box has two switches, one for the motor, the other for the very bright “puck” shaped light tucked into the cavity of the head. The three armed spider was missing its arms from the scrap yard and the cast iron hub had three stripped holes. We used very short 1/2" by 20 tpi bolts, threaded into the casting plus the bolts themselves were internally threaded 3/8 x 16. We then made the arms threaded on both ends to screw into the short 1/2" bolts and to accept the brass insert round knobs. Flats were also machined on the arms in order to tighten them with a wrench. The last thing made was the depth stop rings. My young machinist made all three, threaded and knurled. This was quite a project for a 16 year old with many hours of work. However, he has the start for a machine shop with his drill press plus many skills learned in the process.
