Got started on the spindle sheave today-drilled and tapped (4) 1/4-20 holes for studs to mount the 3" blank directly to the spindle flange; faced a spacer to use in between the two parts so that I can bore all the way through to 28 mm; and cleaned up the face and OD:
Ordinarily there would be a spacer between the outboard spindle bearing and the next part on the spindle; I don't have suitable material to make a bushing out of so turned a .35" wide step into the sheave so it can both bear directly on the bearing; and also fit the plastic shield to help keep junk out of the bearings-took over an inch off the OD-made one heck of a mess!!!
Think a chip hopper will have to be added to my get-it list....
Next step; finish the OD-one more pass to obtain 100% cleanup; and then turn the grooves... Then get the tailstock together so that I can drill a starter hole for the bore-that will be a tedious job...

Got the sheave grooved today; not entirely pleased with the outcome; as I had to run the RPM too high to overcome the lack of torque transfer; so my HSS tool suffered; and I had chatter-due to the chatter; the bit kept moving in the toolpost-my grooves are not perfectly spaced; but the belt seems to fit nicely enough; so it will have to do...

Thanks Dave-soon will know; got it bored and the opposing side faced today-
Can say that having to turn this sheave before declaring the lathe usable has been a perfect learning experience-so far I have realized that my initial plans for chip shielding around the motor would have been woefully inadequate; which is a good thing as I've not yet started on that... Also set one priority project-tool grinder!! Been using a Dremel; and bench stone-as the forum puts it-"not worthy" indeed!! Have an AO cup wheel ready to go; ironically need to be able to turn the spindle for it though
So that will have to happen soon...
Otherwise; want to cold blue the sheave; and recheck my existing spacers to see if I can set the spindle up the way I want it (otherwise I need to modify or make spacers); then I'm going to strip the lathe completely down again and give it a thorough cleaning-some of my oil covers didn't have the retention I was hoping for; and they kept getting displaced, so filled up with chips-also managed to bend one wiper shield up off of the bed in one corner...
Might also turn the necessary parts for the motor fan before taking it down; as then I can completely assemble the drivetrain afterwards...
And still need to finish the tailstock; plus all the friction dials and handwheels-then there's plugs for the series of 1/4-20 mounting holes in the cross slide; a QCTP; carriage/cross slide lock levers; lock lever/screw for the half nut; rapid feed wormwheel and housing for the carriage; etc...
Threading gear train is whole 'nuther set of to-do's...
Glad I stopped on the scraping-the sheave has proven that the lathe is plenty capable as-is; and the finishing touches alone are enough to keep me busy for awhile!
Need to start shopping for barstock for afterwards...

Whew-was sweating over the size of the bore on the sheave; as I really did not want it sloppy-so bored it as close to dead-on as I could-but having not miked the spindle itself; I was worried about the fit being too tight...
It wasn't
-a perfect medium press fit; had to cinch the sheave into place with a spindle nut; between the fit and the preload on the bearing it isn't going to slip anytime soon...
Haven't tried another test cut; but am pretty sure that the torque will be downright awesome!
Guessing the lowest speed I can get the motor to run leaves me with about 70 RPM at the spindle-and the top should be about 2800 RPM-pretty danged happy with that

They are torquey little motors, it should serve you well.

Almost done with the control box-cut vents into it; covered them with stainless steel mesh; and painted it. Added a micro switch to cut off the signal to the control board from the signal generator; much easier/faster than clicking and rotating the knob-only use it to adjust speed now. Also added a reversing switch; so have full use of all possible functions. Got the motor fan on; used an aluminum rotor from a vacuum cleaner; and tweaked my motor mount-drilled and tapped the sheave for a grub screw so that I can run it in reverse-will have to add some provision for belt tensioning though; as it self-tensions running normally right now; so it wants to jump out of tension running in reverse... Wanted to modify the motor mount anyway; as it is such a nice unit that I'd like to make it quick-change to various uses/machines-so I'll add provision for belt tensioning when I modify it again. Make the lid for the control box; mount for the control box; and the drive system will be completely finished; short of sheathing the motor wiring from the box to the motor.
At some point; I'm going to get letter/number stamps, when I do I'll add 'ON/OFF' and such notes on the front panel-will add a pic later as it won't go through right now
Otherwise, soooo close! Already ordered/received a 4-jaw from LMS in preparation for AG parts...
Chip shielding; division rings; tailstock, threading gear setup and I'm done!

Did get it mounted; just need to tweak a few things to get the wiring run through the mount like I think will work...

Got a chip shield for the motor fabricated; and added a means of tensioning the belt-haven't upgraded the motor mount yet; no big hurry on that.

You’ve been busy. Definitely getting close to being easily useable.

Thanks Dave; it's sooo close now...
Getting ready to order the change gears and stuff.
Always seem to end up with a pile of parts or material on the counter so I can walk by and eyeball them, and think about how to pull it all together...
Keep a notepad and pencil on the nightstand so when I wake up with an idea I can write it down/draw it up nd get back to sleep, LOL...

Finished the control box; and got the motor wiring ran through the mount tube-tight; but it fit... Just need to put a grounding jumper wire between the motor and the bed.
Annnd image missing due to upload issues caused by a lack of internet speed caused by those blessed (!) Memorial Day weekend campers posting selfies of themselves flying down towards Mohican State Park...
Grrrr...
Also cleaned out/up the carriage; and made plugs for the tapped holes in the cross slide; so they don't fill up with chips again-easy enough to do with a hot glue gun; just make sure the hole is well oiled and squirt some in-screw it out; and cut to a reasonable length-there you go...
I'd imagine that a quick pinch of the top of the blob would make for a thumb screw of sorts; but didn't try it.
Tailstock next...

Got started on the cover/case today-you know you got lucky when almost every board needed no cutting...
Need to get some more aluminum flashing to make a chip pan and line the cover; as oily splatter don't clean off of wood... Ordered some camphor blocks to put in with it; supposed to be an old-time way of keeping rust out of the toolbox/gun cabinet etc... Smells pretty good too; like Vicks, but without the menthol, LOL...

Cover/case done, lined it with sheet aluminum-so far; no discernable rust on a freshly-turned piece left in the chuck after 2 days; so hopefully the camphor is working...
Rigged up a temporary work light; and made up a quick chip tray-now I can get back to finishing up the lathe itself; without having to worry about rust...

I like where the controller ended up in relation to the machine. My factory control box got removed from mine and mounted on the wall behind.
Cover looks nice too.

Thanks Dave; I really like it myself-so easy to reach up and flick the spindle off/on when taking finishing cuts and miking in-between passes...
Tailstock aligned; not finished-but completely useable. Received my number stamp set; so can get the handwheels and division rings finished now...

Yup
Have an assortment of gears; and the motor/speed control from a old cordless drill-only hitch could be the power supply-but pretty sure I'm OK with what I have...
Not figuring on messing with it for awhile, though-as I've got projects piling up all over the place waiting for lathe time!!
Waterproof nylon cases for my spare 18650's; pill vials for my FAK's; airgun stuff etc...
And the first official production part from it was a plastic bushing to fix a can opener; go figure LOL...

It’ll get a workout for sure. I have a Bridgeport, mini mill, 12x60 Clausing, and a micro lathe that combined do not get used as much as my mini lathe.
The only stationary tool I have that comes close is my homemade metal bandsaw. It gets used a lot.
