I worked as a machine operator and set up my own machines years ago, what is the difference with only forward and reverse and fast or slow, that you need a program to run a simple drill press combo.
Is that an inverter duty motor? They typically have better insulation on the windings because the VFD updates around 20kHZ which may cause a voltage spike burning out the windings prematurely. Long leads to the motor make this worse but yours are fairly short. Also at low speed, if the fan is attached to the motor it may not run fast enough to keep it cool. An external fan may be necessary. But if you run 30-60 Hz you should be fine. Also most VFD can't run less than 6 HZ because there is insufficient torque. Maybe your drive is made to run with full torque at zero speed. If so, sweet.
Mustie needs to have at least a gallon of cutting oil on hand in an old fashioned oiler can. I used to have one that I rigged up with a small pump and flexible tube I could aim at the stock I was machining with a catch tray underneath so I could filter and reuse the oil. I still have a quart of that cutting oil and a my old fashioned oiler can I'd use when I cut metal with a hole saw.
I feel somewhat spoiled here in Germany… looking at those VFDs and thinking about my absolutely average 63 Amp 3 Phase Main Panel down in the basement. That is three Phase with either 230 V +- 10% at max 63 A per Phase or 400 V between phases. On the other hand Mustie offloading the Bridgeport into his Garage would seem like a piece of cake compared to me trying to bring such a machine downstairs. (No idea if the wooden stairs would even handle the load 😉 )
the reverse function is very handy, and an easy fit. When you power thread the instant reverse is very handy ability. I've been using a VFD for about 12 years and before I used a permeates mag DC motor from a treadmill. Just learn your speeds and feeds and easy on those expensive cutting tools.
I worked at a big time machine shop in the '90's and we had an old Bridgeport that was upgraded to full CNC and the operator loved it like a child. He was a very good operator and did some great work. There is hope for any old machines.
Need some water or oil on the drill and part.
If you have a vernier micrometer and a ruler, you can set the cut and depth and also run it as milling machine.
You just need to learn how to change gears and which does what and where it goes, to get this operable not a programmable machine for watts.

Thank you for explaining that I never knew how that worked.

Most likely the gibs need cleaning, lubricants and adjusted for proper clearances
Fast forward to 20119 …
I am so happy that you now have cameras that can focus properly !! 🙂

Mr. Pete has a course on running the Bridgeport, I purchased it when I got mine. Well worth the money.
I watched abom79&doubleboost to get my info on machining ??
Whatever you do don't touch the two handles on the top of the head when the machine is running but I'm sure you probably already know that
