Sure. And he'd have a piece of crap that would give him a completely distorted picture of what turning is all about and would be worth nothing even close to the money which would need to be sunk into it.

And Bill did suggest a couple of Jets as a possible alternatives, neither of which would have a beginner fighting his equipment as he learns to turn.

And if he decides turning is not for him, or falls in love with turning and wants to trade up, he can sell that newer lathe without taking anything like the financial hit he'd take by throwing money into trying to make that pile of junk behave.

I'm new around here, but I'm going with the assumption that the purpose of this forum is for us all to help each other out as best we can.
Recommending that a brand new turner buy a piece of junk that will fight them at every turn and which will require refurbishing and tuning in ways that would only be evident to someone who already has turning experience is ridiculous. Cruel, even.
Sorry, but it is.

I'm a relative newbie who bought a used lathe a little while back. When I bought mine, it was just the lathe. Even though I didn't have to do any work to the lathe, I was a little amazed by how much I spent to outfit it. A chuck, chuck jaws, centers, lathe tools etc. If you can find one, I'd suggest you see if you can find a lathe where the seller includes some "stuff" with it.

Having to use a wrench to move the tool rest hardly makes the lathe a piece of junk. It only takes moments. Not having a lathe at all is a far bigger handicap.

I am new and have this lathe

Hello all, If you are still reading this thread...I stumbled across it in my search for the spindle thread. I bought this lathe (without the tool rest) for $40, and pieced together a tool rest to get started ... have done some spindle turning. To top off the 'put together' feel of this lathe it looks like the previous owner cut away a bit of the bed to make room for larger bowl turning.
I guess it suits my purposes for now (just exploring) but would still like to know the unconventional threading and where someone would get such a thread (it appears to be either 1x14 or 1x16tpi).
Thanks for any info.

I think the bed gap was factory. I would have a machinist make an adapter to make the spindle accept 1-1/4-8 threaded accessories. This is a much more common thread, and would allow you to to use the same accessories if you upgraded lathes.

It's called a "gap-bed" lathe and it's not at all unusual to see that type of bed on smaller and mid-size spindle lathes. However the lathe really isn't suitable for turning any bowl that would be large enough to make use of the gap. The reason is that the minimum speed is way too fast to start roughing out a bowl. Couple that with the very light weight design and you would have a lathe that you would have to chase around the shop.

In all seriousness, it would present a hazardous situation because of the likelihood of tossing the bowl due to vibration or especially if there is a catch.

It is easy to measure the thread size and you will need to know it before you buy any chucks or faceplates. The thread could be 3/4 X 16 as that is a common size. You have a choice of getting chucks and faceplates to fit your thread size, but it will limit you to getting them from either Oneway or Vicmarc -- or, your other option is to get an adapter to go to a more common size such as 1 X 8 or 1 1/4 X 8. If your spindle is 3/4 X 16 then you can get an adapter from Oneway. If you need to match an unusual thread size on the spindle then your best bet is to go to Best Wood Tools. This would cost less than having a local machinist custom make one for you.

Boice lathe

Thank you for the replies. I should have been more clear ...in addition to the factory gap in the bed someone did indeed cut away more of the bed such that the tail stock will not meet the head stock for alignment inspection etc (the cut is not completely square and so is obvious but the lathe still feels solid).
I keep forgetting to bring home a thread pitch gauge but am fairly sure it is 1X14tp (I count 7 threads in 1/2" but can confirm when I have the gauge).

Would someone please estimate the maximum bowl size that could be turned safely on such a lathe?

That depends on how good you are at rounding and balancing a blank. If you are bad it it about 4-6 inches is about all you can do. If you are good at it maybe a shallow 10 inch bowl. If you add a jack shaft to slow the minimum speed and add weight to damper vibration you could turn the biggest bowl that will fit on it. Adding weight Is a good idea even without the jack shaft.

Probably 1" - 14 TPI, not that common.

When measuring the thread pitch, don't count the first thread at the zero mark on the ruler. Here is a link to Best Wood Tools. They have an off-the-shelf adapter that is 1 X 12. If the spindle nose thread really is 1 X 14, give them a call and they can make a custom adapter for you.

The spindle thread is, it turns out, 1x14. I did contact Best Wood Tools (thank you) and it would be close to $100 in the end. The lathe continues to confound as the tail stock live center is a thread on ergonomically ill shaped affair with a somewhat crunchy bearing (it's a tiny point inside a larger ring that threads onto a straight adjustable shaft). I have not come up with a way to fabricate this defunct part...so now pondering getting what use I can from the lathe (perhaps with a fabricated face plate) while it lasts w/o trying to upgrade (unless it can saved from complete defunct-ness somehow).
