Got the mill moved into its new spot, hooked up the DRO, task light, and the auto feed. Got the motor wiring sorted out, waiting on the VFD to get it running.
Squared the quill to the table with a try square, need an R8 collet to set up the dial test indicator to tram it in properly. Collets, end mills, new drawbar, clamping set, boring head, end mill holders, shell mills, face mills, insert tooling, fly cutter assy., etc all "in the mail." Actually, have the fly cutter and test indicator but no way to mount it yet. Meanwhile, disassembled the "free" vise and removed all the metal shavings that packed the screw and kept the vise from opening more than a few inches. Cleaned it up, oiled it and put it back together. Not much to look at, but seems like it will work for a while, at least. Lapped some minor burrs off the jaws. I'm now thinking I might try boring an engine with it. Need a scrap block to practice on...

If you bore a block, bring the knee up not the quill down, it's more accurate.

Congrats on your mill. Hope it works out well for you. Spindle speeds are the same as a Bridgeport. The VFD will "remove the hole" ( or gap ) between high and low range.
Are you familiar with tramming the head in? I have a write up on another forum I could copy if you would like. Jeff |

Put the indicator on the vise and the top of the jaw pads are perpendicular to the quill within .001" (.02 mm) when the table is moved left and right. Much of it was within .0005"/.01mm Have not checked the inside surfaces of the jaw pads yet but they look pretty nice. The test indicator is actually in .01 mm divisions, so each division is a bit less than half a thousandth if my math is correct. (2540 divisions per inch). I'm calling it a half thousandth, close enough for me. Some end mill holders and an R8 collet rack showed up in the mail. No VFD yet, Amazon said it was to be delivered today, but I'm rural, so UPS is usually a day late here. Can't wait to get it running.

Got the VFD hooked up, jury rigged a DPDT toggle switch for the time being. Will swap it out with a proper switch once I order one.
It's actually pretty neat that it controls speed by varying frequency to the motor, running the 3 ph motor on 220VAC single/split phase. Here's a short video. https://www.youtube.com/watch?v=hjkWge5BEkU

Your ramp up and down seems pretty slow. I’m sure there are settings to change.
Can you set up a separate forward and reverse switch? Most VFDs can. I definitely would if you could. Would help in power tapping holes. Have fun! Edit. You should have a big/ easy to hit switch to kill the spindle. (E stop). Just in case.

Installed the new on/off switch. I managed to clean up a piece of mild steel today with one of the nitride coated end mills. Seemed to work great. Tried a carbide insert face mill and not much joy. I understand I need higher speeds and heavier feed for carbide, so I need to step back and look at my setup. Got an R8 collet set, an R8 drill chuck, an R8 to MT2 adapter, a new drawbar, an edge finder, and a slitting saw arbor in the mail yesterday and today. Waiting on the boring head and a 5C collet set with square and hex collet blocks, and a few other things still in transit. Having a lot of fun learning this new machine.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
