Delta Drill Press

KV Bruce · Dec 7, 2016

I recently obtained this older Delta drill press with a Power-Craft extra spool. Plenty of speeds to chose from now but not really sure I need them. Thought I would share something different.

Interesting and nicely-done modification. I do agree that you don't really need that many different speeds. Thanks for posting the picture.

It is nice to have the slower speeds for larger drills and hole saws.Most drill presses with only 4 speeds lack slow enough speeds. Even though it looks ugly, keep it.

Someone was probably drilling mostly steel for it to need the lower speed.

I would keep the reduction pulleys in place, just a matter of moving the belt to get it faster, if you need it.

I guess I would have inverted the motor to make it more compact, but it certainly is nice to have so many speed options.

You may not use all the speeds. After a time you will find out how to run it to make it fairly easy to get some slow speeds for drilling larger holes in metal, hole saw in metal, etc, and a few faster speeds for small holes in metal and wood. You will find for lager holes in metal that require a lot of power/torque if the upper belt is on the largest spindle pulley you will have less belt slippage. A lot of drill presses need what yours has. Keep it as is and learn to utilize it.

Nice old rig. I rarely use more than 2 speeds.
I'm having a hard time finding a new motor for my drill press.
Its a harbor freight type different company.
After the fire the drill press is OK just the motor is shot.

I have one very similar! I had to add a countershaft to slow it down too. Mine also has the power feed, but I need to get that fixed. Very good machine.

That's a great looking set up. If all you ever do is drill holes up to 3/8" or so, I'd understand why you might not see the need for so many step downs. Chuck up something a lot larger and it'll prove it's worth.

Mine has a a treadmill motor on it and it still won't go slow enough. For the big stuff I use an old Buffalo Forge hand cranked, power feed blacksmiths post drill. I've run a 2 1/4 drill bit with that one!

For any of you math majors, how many speeds are possible with this set up?

KV Bruce · Dec 8, 2016

Steve, Thanks for your comment. But the tool came from his woodworking shop along with some large adjustable type hole saws. I also picked up a Craftsman planner and a Walker-Turner jointer and a 14" Delta band saw. Guess I'll have to get into woodworking but I need to complete my 1947 BF Avery A model first.

16 speeds without making the belt cross to an unaligned pulley.

KV Bruce · Dec 8, 2016

I had to take my shoes off but I came up with 16 too.

Here is a chart I came up with. Had to make a few guesses as to pulley diameter and motor RPM. Picture of Drill press shows the A - B referred to in the chart.
