As you can see this column mount style fits my 900 Series just fine with no need to cut off the factory boss or flip the motor mount plate. Belt sizes I used noted below. The column adapter has a socket head driven spreader acting like an internal collet to snug the adapter against rotation in the column.Only snug until you cannot rotate by hand. No more pressure is needed as there is little or no operating force trying to move it. As shown, the adapter is positioned generally so bushing is to one side of press and pulley yoke is swiveled across center of the column tube towards the other side of drill press. This keeps it from getting too far off center to interfere with belt guards.
It fits all my drill press's with guards. I have no idea what dimensions yours are. 1 Your machine MUST have a column with 2.375" (2 3/8") bore. 032" over or under is OK This is typical of many drill presses with 2.625"-2.750 columns. If you need to fit different inside diameter, please contact me.2 The column must be capable of protruding through the top of the head casting. 3 Made for 4 groove pulley system requiring 1/2 belts or 4L belts. Converts your 4 speed into a 12 speed with both slower and faster speeds. 4 Flipping the motor drive pulley over is required.
All of them I have seen can be flipped without machining. I have not seen yours.
5 Adjusting the head height on the column is required to find best belt alignment. Don't worry, V-belts can be run very far out of alignment with no issues. This is not a sensitive setting.6 Your belt guard (if so equipped) bottom or base plate must not cover the drill press column. If it does, a hole must be cut approximately 3 in diameter to reveal the tube opening. This item includes: Metal pulley loaded with ball bearing, pivot yoke, bronze pivot bushing and additive manufacturing column adapter machined to accept a bronze bushing and securing hardware. This item is made by me including sourced and modified parts. The drill press and belts shown are props used to show application of slow speed update kit and not included.
MEASURE THE BORE of your column. If your bore is different, please send me a photos of your drill press, caliper measurements and model of drill press. I just might make a special one for you. Following information is not warranted.
Provided as a record of my experience with my machines and sourced information. Drill Presses I have installed the 2.375 ID size on: (I can't own them all, many from the 30's through the 70's used this size column tube). Walker Turner 900 (Mine is 2.75od, 2.375id) V-Belt quill 4L290, motor 4L275 are perfect belt sizes on my 900 series Customers report: Add yours to this list! DO NOT RELY ON ABOVE LISTS. It is up to you to MEASURE YOUR COLUMN TUBE ID.
