I'll make it clear, I am NOT posting this to brag about this set up!
You lot have so much talent I'm embarassed to do any more than ask questions here...which is kinda what I'm doing now.
This is a swap out of a 3 hp 3600 rpm 3~ motor for the original 2hp 1750 1~ on a Industrial Hobbies mill.
The original has a B5 flange mount but the Baldor came my way so extremely inexpensively I couldn't resist.
All was going well until I realized the bolt circle of the motor was shaded by the bolt circle for mounting to the mill.
What you see is an inelegant but I hope serviceable solution I came up with.
Button head bolts sit in countersinks and the spacers give me room to tighten the other bolts to hold the whole mess onto the mill.
I keep thinking I should have used .75" plate so I could index the raised edge on the mounting end of the motor to the adapter plate in a more secure manner than just the 4 button head bolts on the spacers. I would have relieved "pockets" on the perimeter for the mounting bolts and to swing a wrench.
I don't think it will move but I can't test it until the VFD gets here so I thought I'd ask if you see any glaring problems?
