Correction: I don't have tap sockets or whatever, and it was the tap spinning in the Jacobs 33 chuck--the DP never hesitated--except for the lag Outlaw described. My bad.
This is the motor I'm currently running:
I have a reverser switch so tapping with the DP is safe and easy.
I use a VFD with a 1 HP 3 phase DP motor and I have yet to move the belt/pulley setting below the highest speed steps. For most drilling tasks low speed torque is just fine. If I ever need even more torque I have 4 lower speed pulley settings to choose from. I can't imagine any scenario where I would ever need more torque. If so, a DP is the simply the wrong machine for the job.

Tapping with the tap in the chuck is ridiculous IMO. Reversing tapping heads are the way to get the job done when you have multiple holes to tap. Far better control.Correction: I don't have tap sockets or whatever, and it was the tap spinning in the Jacobs 33 chuck--the DP never hesitated--except for the lag Outlaw described. My bad.

Don... Notice the Delta 5 ribs on the pulley cover... This is a much wider cover that allows space for a larger diameter factory pulley...That was great advice. I removed enough pieces to make it possible to get it out of my car.

The 5 rib model are indicative of a Slo-Speed DP set up for 470, 780, 1300 and 1950 RPM
The 4 rib model are indicative of a Hi-Speed DP set up for 680, 1250, 2400 and 4600 RPM.
If you want to go slower Member JZiggy offers an excellent 3rd pulley MSA unit

Very true--but I don't own one and probably can't afford one. Seems like those run around $700+--used.
Mostly, I use the DP to start the tap in the hole so I can get it straight, turning the chuck by hand. But this time, it was just soft aluminum so I said to hell with it, it's only #10-24--of which I have several taps--let's give it a try.
I was running the chuck at about 50 rpm, and with the big DC motor, the chuck stops instantly when I turn the switch off. My reverser switch is an On-Off-On, so the chuck stops between forward and reverse. Actually pretty easy to use.
I need to get some tap holders for the chuck and more spiral-flute taps.

I am a big fan of industrial grade DC motors on drill presses and belt grinders. Often the motors and control electronics can be found for cheap on EBay. They are usually NEMA 56 sized so mounting them is easy. They also do not have the annoying audible whine of most VFDs I see.

Needed to order belts for my Multi Speed and my bandsaw. Thought I would post these 2 sites. Been ordering from both of them for years for all my belt needs and no complaints. Vbelts4less tends to have better pricing for the belts I order by a little bit. Prices are good and you don’t even need to get out of the house!

I got my set-up from a treadmill a friend was throwing away. MC30 controller board, etc. The motor that came from the treadmill was rated at 2hp--at 20,000 rpm. I found this 1/2 hp at 1,800 rpm on Ebay.
The parts I salvaged form the treadmill.
Mounted. I later added an Amp/Volt meter.
One variable-speed, reversible drill press.

Wow, I've mentioned my Rockwell a bunch of times in this thread but never posted it?
A few pics here, but also the build thread:
Control box: I have since added a mag mount LED light for the work area - the "night light" on the back of the box was the planned receptacle for that. The switch in the middle is for the light, the original main switch turns the motor on/off and the push button starts it:
It's table as bought before cleanup:

Treadmill motors certainly have “bang for the buck”. I looked at using them on my drill presses, but was fortunate to find industrial DC motors for cheap locally. Recently I ran into a NIB 3/4 Hp 1800rpm Emerson Electric DC motor for $20. it was a nice upgrade to the Leeson 1/2 hp motor I was previously using.
for ease of integration, I keep eye out for used Minarik MM2xxxx NEMA 1 enclosure DC motor drives. They are 120VAC (for 90VDC motors) and 240VAC (for 180VDC motors) compatible. eBay is a good source for them.

Anyone able to give me a value on an old Arboga Maskiner GM2508? I inherited it from my dad’s machine shop. I have a buyer, just don’t have a clue where to price it. Probably not pretty but it was in use until my dad got sick a few months ago. No clue on actual age.

Quick refresh, obviously paint, but new motor, motor plate, switch, cord,belt, bearings, table/ fence and a cover plate to keep debris out of the base. Rolled it out for a few pictures and back in it's spot and back to work..

I'll say. You've put some hours and elbow grease into this one. Nice work.
