This one just fell in my lap. W/T style Rockwell drill press with automatic variable speed/pressure advance. It sat outside covered for about a year. It came with 4 commander multispindle drill heads. The extra drill spindles sat in a bucket that filled with water. They look like they'll clean up OK. This machine originally came as part of a multi head machine on a shared base. I designed and had fabricated a heavy steel base for it. For a table, I utilized an older crafsman TS top a friend had given me years ago. The table is made perpendicular to the quill by the use bolts "captured" in gussets on the base that thread into original holes at 4 corners of the table. I will make a solid throat plate for it soon. This model came with either a #2 or #3 Morse taper. Mine has the #3. It also has the optional additional return spring for returning heavy items like power tappers, etc. I will use only one spring for the work I do. The previous owner had tried to give this machine away on 4 separate occasions. Each person flaked. When he called me, I said "I'll be there in 20 minutes."

The machine really required no restoration. Paint and badges are all original. It is missing the cover plate on the handwheel. The previous owner had run the head too high on the column and had 'slipped' the casting off slightly on the top. After removing, cleaning and resetting the column, I removed the elevating mechanism as it seemed a bit stiff through part of its motion. Turns out the 3" long 5/8" shaft that couples the crank worm gear with the rack gear was bent! Not sure how it happened, but it is currently being pressed apart and a new shaft made. Most everything else only required a good cleaning/lubrication. Installed a new Jacobs 1/2" chuck in place of the commander stub taper. Haven't checked runout yet, but it seems to run very smooth. Powered by the original 1.5 HP 3 phase motor and Furnas starter.
