Walker Turner Delta Rockwell Atlas Craftsman Drill Press Slow Speed Assembly

Slow speed drive system fits entirely inside belt cover on my Delta Rockwell drill press shown. Reduces RMP at chuck by maximum of 1/2. Slower cutting speeds work better for metals. Larger diameter cutters such as hole saws, paddle and Forstner bits cut better with less heat when turned at proper speeds.

Small diameter bits require higher speeds. This pulley while capable of cutting your final output speed in 1/2 is also capable of doubling it making bits under 1/8 must less fragile. 1 Your machine MUST have a column with 2.5 bore. (Shown in photo, caliper upside down). This is typical of many drill presses with 2.750 columns. If you have a different size, 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 get the belts in line. 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. 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. 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.
