Congrats on the little addition. I have my second due in February. My first is 2yrs old. He sure make it tough to get out in the shop but some how I find the time.

Congratulations. I have four of my own. They make it hard to find time.

PM45 CNC Build in Progress
Finished welding the stand together. Now I just need to plasma cut the hole in the top plate and paint it. Then I can mount the plywood lower shelf, the storage bin coolant container and the multi-drawer thingy on the front face.
Overall I'm pretty happy with how it came out. The little plastic storage drawers for the front are a perfect fit and will hold and organize end mills and tools nicely.

Jeez that's one thick top plate.
Heavy duty. Nice work.
What a fun project! You've got me thinking about tearing into my 45 clone.
I was going to try to cnc my x2, but I think I'd much prefer working on "the big boy"
I'll be following your progress.
Just a little work tonight, drilled some pilot holes for pinning the pulleys to the shafts of the motors and ball screws. Using 0.125" roll pins for that action.
Hoping to finish the stand and get it painted this weekend.

This baby arrived today, and my 4 year old complained that "Dad keeps getting heavy boxes for his milling machine", relating to the fact that she typically hides my smaller packages around the house for me to find when I get home, but these packages are now too heavy.
Got the Z Axis block sized. Made a huge pile of chips as the stock was a bit larger than needed. CNC would have been nice for that action.

I see that is a 480V motor. What are you going to power it with?? I assume your only available source is 220V/1PH. Did you find a VFD that will step that up to 480V/3PH?

That is a 230/460 motor. Weird they don't have any 230v info on the name plate. If it were just a 480 motor it wouldn't have the low voltage wiring diagram. Automation Direct carries these motors. Their data sheet says 5.8A at 230V
That Marathon motor rocks!!! Your going to love it.
Yep, I bet your four year old had a real hard time with that box

Hi guys,
Not trying to hijack the thread here but something caught my eye. Regarding using a 460v motor at 230v. My mill came with a 3 phase motor which had 460v and 220v mentioned on the nameplate, and I simply plugged it in to a 240v 3 phase inverter (powered off my 240v two phase mains) and it works fine. Seems to be at full power and doesn't seem to get hot or anything.
Was I supposed to rewire the motor in some way? Am I loosing power here?
Cheers,
Rich
Yes, they generally have a label inside the junction box that shows the connections for High and Low voltage setups.
I can tell you if your wired for 480 volts and your only running 240 volts then your getting only about half the power out of the motor.
One easy way to tell, besides from just looking at the wires, is if your using a VFD, look at the current draw at no load or full load and compare it to the name plate on the motor. At 480 volts the current will be right at half as much as it will be on 240.
Example: Your motor should show FLA (Full Load Amps) 5 / 2.5
That would be 5 amps at 240 or 2.5 amps at 480
Some motors also have the No Load Amps. That is easier to use since you might not be able to fully load your motor on your mill during this procedure.

The motor can be wired for either 230/460.
On the first picture you see in the name plate the voltage and current. Is supports low and high voltages, very typical.
The wiring for the low voltage is here in the second picture as depicted on the motor T-Lead diagram.
I don't use the plasma cutter too often, but it really gets it done when you do. I could use more practice as well, but it is nice to have. If some day I get the stupid idea to re-live my teenage years I'll build a rock crawler and the plasma will be busy.
Hole in plate for easy access to the Y-Axis for adjustments.
Mess. I was holding back not sweeping up saw dust after each cut. But I got the base and the drawer mounts all built. I also painted the stand gloss black. I just need to go get a few screws and I'll bolt the things on and officially consider the stand finished.
Next up the pan.

Alright, the stand is done. Now I'm finishing up a few small details on the design of the pan with removable front face. Gonna print a drawing with all the lengths of tubing and angles I need to cut so i can go to town with the chop saw.
Probably never look this good again.

Dang, Looking good. I noticed all the diagnal cross bracing, that is a very good thing!
Richard
Looks very nice. It's always best to triangulate when possible.
That does look good, and sturdy. How much does it weigh?
Looks good. Bet it was fun wrangling that piece of ply into the bottom section.
Matt
Looks great... is the hole in the center for a drain or access to the underside of the mill?
I have been drawing my pan and don't want the drain under the mill in case it needs to be worked on so I think I am gonna do one drain on each side.
