The lowest cost and most produced is the 6203 . I used where a 6201 or 6202 could been used but cheaper to use the larger bearing. The next bearing I used 6205 . So only had to? stock two sizes. I

Like the power feed. I have DC motor sitting desk after finished othe parts of lathe . What ratio from top to bottom speed? Or top RPM to low RPM? Dave

Your next step is to use the motor for threading. You already have ddido 90% of the work. Then you think “that was not so hard”, and add a smaller motor to the cross slide and have a full CNC lath

I’m working on a project that will use 60 sealed ball-bearing units. It's very early in the design and I’ll likely change the size of several of them and have to buy more. I always buy about 10 at

I have just finished added a stepper motor to my leadscrew to get nice even passes. Just tried it on a bit of scrap and it worked well. A 240v to 24v psu, a stepper controller, a Nema 23 stepper motor

*FYI If buying the 6206 as a manufacturer it cost $1.10 each. Try buying that bearing at the retailer leave.* *I think the other number for ball bearing is 80206 it same bearing. I would buy as a

I was think most mini lathes use 6206 ball bearing not tapper. FYI If buying the 6206 as a manufacturer it cost $1.10 each. Try buying that bearing at the retailer leave. I think the other number for

I had the same problem 40 years ago. I traced the threads in a lathe with upside-down HSS cutter. It was cheaper to buy a new puller than to buy the tap and die need. I could not believe when found

At one time I did a LOT of PVC machining (and some ABS) when working nights after my "day job" at a company filling in for the vacancy in our one-person machine shop for six months.? The parts were

@Roy said "Scraps of PVC pipe are excellent practice material." Delrin (Acetal) works better: cuts better (almost like Aluminum, which is also good for practicing).

The OP's lathe alignment is far better than mine (LMS 5100). Now that the tapered roller bearings are in the headstock, I may start the tedium of getting a proper headstock to bed alignment. -- Lone

Dear Buffalo John, Thank you for your explanation(s), it is much appreciated. [BTW, A great use of the (very) technical term of ‘mushing’ - language evolution is not dead or confined to kids.

Yeah Dave, that's what I thought too. I honestly thought my thread pitch gauge was wrong. It's not, LOL!??I even took one of the inserts to my local hardware store to see if it would screw into a

I would recheck the threads. 9/16 x 18 NF is very common size. 9/16" x 12 NC There is also 9/16" x 24 NEF too. 9/16" 16 is used on pulley pullers and other tools. Dave

I've never thought the factory adjusted anything! I've always thought the lathes were shipped assembled because it was cheaper than packaging all the components separately ;-) The first thing to check

Exactly why I wanted to know how to single point and in the end converted my lathe to an electronic drive setup on the lead screw.? The die I needed for my last project ( McMaster Carr lists one 9/16

That's fine until you find yourself trying to repair something that requires a threaded part you don't have a tap or die for. Scraps of PVC pipe are excellent practice material. If you have a tap of

They're also non-sparking, a nice safety feature when working around flammables. Roy

OK, so the ball definitely has to be loose enough to roll with the turning of the work. That wasn't clear to me from the video, which was in a foreign language so I couldn't listen to it. If the ball

Well, this process is a smoothening version of knurling, called ball burnishing. It works the same way in that the rolling item against the work imprints the surface of the rolling item on the work.
