Clausing 1771 Drill Press Restoration

  • 1,257
  • 18
I picked up a Clausing variable speed drill press from a Craigslist ad. I offered the guy $200.00 and he accepted. The drill press was in decent overall condition, and had a new motor on it. I disassembled the machine and cleaned up and painted everything. Mechanically, it was in very good condition, and the only real repair work I did was to straighten a few of the handle arms. One really nice feature is the table lift, which works great on that heavy table (btw: the table doesn't have a single drill mark in it!) This is my second Clausing variable speed drill press. The first one is in my metal shop, this one will be in my wood shop. Jack Fort Loramie, Ohio

VN Finally Got A Slotter Attachment

Finally picked up a slotter attachment that I have been looking for. Probably paid a bit much, but it's practically new. Stripped it and cleaned out the old gunk. Back together already, quickest rebuild yet. Missing one oil cap and the arbor, but I have a print for the arbor. All I did was clean it. Jason

Power Z Conversion For PM45

I have an early model PM 45 mill that has the manual hand crank for Z elevation. Since I just reorganized my shop and a toolbox is placed nearby, I'm going to attempt to convert it to powered elevation using a heavy duty gear motor that I've had for a long while. I'm not 100% sure this will work to my satisfaction. The odds are maybe 70%... We'll see. I'll outline the design considerations as we go. Here's some pictures and explanations... Here's the mill with crank handle removed. I put a wrench on the shaft flat and roughly measured the torque needed to raise the head. Holding the wrench about 1 foot (little less actually) from the point of rotation, I measured about 8-10 lbs to move it. This was measured by setting weights on the wrench which is a little inaccurate. Anyhow, I'm assuming it needs 10 ft.lbs to keep it in motion. Here's a gear motor purchased at a surplus shop that I've had laying around for years. This motor is used in mobile-home campers to...
