1) Your machine MUST have a column with 2.312"~ bore (range .032" under or over). (Example measurement of different drill press shown in photo, caliper upside down). If you need a different size, please contact me. I have eBay listings for many sizes. 2) The column must be capable of protruding through the top of the head casting. (See caliper photo.)
3) Made for 4 groove pulley system requiring 1/2" belts or 4L belts. (Converts your 4 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 line up belts.
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 2.375" in diameter to reveal the tube opening.
This item includes: Metal pulley loaded with ball bearings, pivot yoke, bronze pivot bushing and additive manufacturing ABS column adapter machined to accept a bronze bushing. This item is made by me including sourced and modified parts. The drill press, belts and my hand are props used to show application of slow speed update kit and not included. Belt sizes you need are unknown to me and not provided. Buy 6 feet of Fenner 4L link belt for a buy once setup. Fenner's are adjustable length, run quiet and are of high quality.
Don't buy this hoping it will fit. MEASURE THE BORE of your column. If your bore is different, please send me 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.
MEASURE BEFOR BUYING. It is up to you to MEASURE YOUR TUBE ID. This item fits 2.312" tube ID. Let me know if you need something different.
This is a slow speed accessory only, not an entire drill press. A sample drill press is shown to illustrate fit and function of device and NOT INCLUDED. You must have your OWN drill press.
