Enco 8x30 Knee Mill weight

Well, I got the mill outfitted with a VFD today. I used a 2 hp motor, 145T frame, 1750 rpm. The motor bolted right up after I enlarged the holes in the base by 1/16”. The shaft is 7/8” where the old motor was 19 mm, so for now I picked up a single 3 1/2” pulley from tractor supply. I don’t have a boring bar large enough to bore out the original step pulley. I was able to reuse the belts that are like new so that is good.
It is scary quiet running. I’m deaf in one ear and can’t hear out of the other so it’s hard to tell if it’s running. While I was at it I put felt between the belt lid and the top frame so the lid doesn’t rattle now either. I plan to stop by Fry’s tomorrow and pick up a red and green LED to put in the run station to show green for running and red for not, can’t hurt to have the visual. I don’t like the run station but it’s what I have for now.
The control is very basic. Forward, reverse, stop, and jog forward and reverse. I have a MachTach for it that will mount under the DRO. The speed pot will be in the box with the MachTach. I used a Delta VFD with a brake resistor.
I hope to put the tach together by the end of the upcoming weekend.
It has come together very well, I’m happy with it.

VFD setup looks good. I need to upgrade my G1008 to VFD and 3 phase motor. My original motor is quiet and smooth, just single phase so only pulleys for speed change.
 
very nice! I have a treadmill motor install to do to mine this summer - can't wait to have variable speed at the turn of a knob again.
 
Nice wish I could get out to mine . Oh well nothing I can do about it from a bed in pain . Like the way it sounds nice quiet running is good. I too only have one ear to hear. Your installation looks good too.
Great job now it's time to get it dirty and build some projects.

Looking forward to seeing yours finished as well. Post it up when your done.
 
Well I finally got the MachTach mounted and working. I started with a Serpac case and IR sensor but ditched it for a Polycase and a Hall effect sensor in the end. I put the magnets on the bottom side of the spindle step pulley and the sensor under the belt guard right near the oil cup on the right side. While I was checking operation tonight and put six magnets on the step pulley and turned it on the see it work. I turned the knob just a little too far and slung magnets all over the garage. I only found 3 out of 6. The magnets are glued in place now, not going anywhere. All seems to be working fine.

TM, I know it has been some time since you posted these things but was wondering if you happen to have any shots of the lead-screw extension you did for the x axis power-feed?

Also wondering what size draw-bar is that autodrawbar turning. My original HF draw-bar is about 12" and 1/4 with 2 inches of threading. I have the same type of pneumatic DB setup and have roughly calculated, but again seeking advice from those who have gone before me.
Trying to plan mine out and grabbing others tactics.

I apologize. I sold that machine a couple months back and have upgraded to a fullsize Lagun mill. The draw bar that was in the machine was made by me. The power drawbar had a tendency to chew up the end of the drawbar. I would just weld a coupling nut to the end of 7/16 fine thread allthread. I really don't even remember what it looked like to be honest. LOL!
