I want to tell you from experience I've got seven lathes sitting in a shop. Forget the Rube Goldberg setup. To start just go by yourself and inexpensive mini lathe. With a few simple mods it'll do what you want. If it turns out you like what you're doing and want to go with something even bigger and more capable. Surprisingly you won't get rid of the mini lathe cuz it'll still have uses. making ferrul and various things.

And that's all I'll say on the subject i know you're going to do what you want but I hope other people who have mini lathers and have had a lot of fun with them working on cues will chime in. Also you can get an inexpensive wood lathe long enough to put a cue between centers for rewrapping finishing polishing and a whole bunch of other things.

As an AZ native, I thought Yuma was a weird choice, but now it’s gonna be super fun. The wife decided to go and use it as a chance to see her best-y who is driving from So-Cal. Right in the middle for her and us. Then we scored the hat trick, an ABnB that allows pets, has a pool AND a pool table.

The girls hang out by the pool with the dogs and me and a buddy will hang at the tournament and watch the monsters!

I will find you Bob, I haven’t forgotten the virgin screwdriver.

Gonna be HOT!

Homemade Tip Replacement Lathe

I purchased parts to make a homemade tip changing lathe. There are a couple other threads similar to this but their picture links are broken.

I already made a speed controller out of spare parts that I had, which generates 270 oz-in (1.4 ft-lbs) of torque from 100 to 1000 RPM... I think this is enough for tip shaping work...

I am planning on directly coupling the motor to a chuck. I'll use cloth or electrical tape on the joint end of the shaft. The tip end of the shaft will fit though a pillow bearing with collets. My amazon order is under $101 including shipping.

The bearings have set screws in them which I hope will allow me to adjust them using a dial caliper (which I don't own yet). I just plan on using a block of wood with a razor blade screwed into the top as a tool, or maybe just a block of sand paper.

Is there anything I am missing?

With the parasitic losses of the crap bearings, I bet against that motor ever having the torque necessary at the speed needed for even cutting tips.

I am only using one bearing, and I can adjust the driving torque up to 2.5 ft-lbs if I need to. I'll just have to point a desk fan at the stepper if I do that.

But even if I lose 10% to drag, 1.25 ft-lbs is still plenty for sand paper.

Most cue lathes have 0.75-1.5 HP motors, which produce roughly 2-4 ft-lbs of torque.

Finally I can increase the clock speed of the controller and use a belt system for more torque at the same speed. Lots of options.

I watched a live stream of an 800 Fargo rate player, competing in a $20 weekly tournament, recently.

Happens all the time in NYC! It's one of the nice things about living in a major metro area. They'll just randomly drop by and play our local tournaments, both handicapped and unhandicapped.

Francisco Bustamante just dropped by a couple weeks ago and took down one of the open ones. Here's me "beating" (aka shitting in the 9 ball a few times 😂) Moritz Neuhausen a couple years ago in a $80 handicapped tournament: Login to view embedded media
Just in the past two years, I've played 4 players that were rated 790+ just in these tournaments, and I don't even go to that many of them.

Besides the joy of DIY, is there a benefit over a ready product?
I’m sure that there are some cheap ready products out there just for tip replacements.

Do you need it for personal use or are you planning to offer repair services?
For personal use, you can just do it by hand.
If you’re going to offer repairs, then you might want to consider a pro lathe that can do more than tip as you’ll probably grow into that direction and it’s cheaper to get the right tool from the beginning

This is just for personal use. Since I already have half of the parts, for $100 it is worth just making it. I will use it about once or twice a year.

The only reason I am making it is because I have a lot of motors with nothing to use them for. It would be a shame to keep letting them all sit there.
