ugh, that guy again?
Turning the work too fast
stick to internet rage, bud
if the chips ain't coming off blue, you're wasting your time
sometimes bright red and sparky is good too
Turning the work too fast
that is like the ultimate size
16-36 might be the only other great one to start with, but shorter beds are hard to find
OP... You need some really deep pockets to play.... Fucking 4-jaw can set you back north of $800 and not even offer a reach around. Oh shti, I forgot; you need dial indicators to center that bitch. Good luck..

Spoken like someone who doesn't have to pay for their own tooling.

That is one hell of a score. Great size, I wouldn't want anything smaller.
Well this machining hobby may have to wait until later in life, not due to lack of interest but due to the costs involved. I talked to a freind of a relative who has a small lathe and makes handles for things and misc small parts and it looks like all the random tools for the lathe end up costing more than the lathe itself. He was adding up a couple chucks, live centers, holders, cutters, knurlers and various measuring devices and quickly got to over a grand not including the lathe. Taking that into account and thinking of the things I would want to make, it would cost substantially more than I can spend right now.
I geeked out on yootoob vids and it really makes you think differently about things. I was looking at an output shaft I had kicking around and was thinking of how many different tools it would take, how many different steps and what order to do them, and how many hours it would take to produce that part. You really start to appreciate these things once you realize the amount of work that goes into them

more like spoken by someone who sharpens their used up carbide inserts
ETA: seriously, low surface speed causes terrible surface finishes for me
even threading; run that shit at least 100sfm on soft steel and something like 50 on alloys
Is your friend located in a shithole that never had any manufacturing and therefore doesn't have people's basements and garages chock full of used tooling?
Looking into getting started with machining small parts. Been eyeing a Taig for a while now....
I did not sleep much last nighg, but lets say you had a small lathe, could you use it to make a larger lathe? And use that one to make another larger lathe?
Same with 3d printing. Could you 3d print another 3d printer?
How do you make gears with a lathe? Use the feed like a shaper with the turret locked?
I've got a hokey ass 3n1 shopmaster mill/lathe/drill combo with power feed and DRO. Bastard is handy as fuck and I use the shit out of it. Its a 17x20 lathe (yes it swings 17"). If you can get a hold of a lathe do it. The tooling doesnt have to be expensive. A holder, grinder and tool steel you shape to cutting form is all you need to begin. Cheap triangle insert tooling can be had at harbor freight... its poopy but it works..
Want to make pins and bushings for an offbrand tractor... Done
Want to make a rotor hub opening fit a currie axle.... Done
Need a custom bushing/spacer... no problem
Want cam bearing or input shaft bushing install tool.... wham instant gratification!
17" swing, that is pretty impressive. I looked at several of those things (although much smaller than yours) when I was getting into machining. I passed on them because many don't have powerfeed or the ability to cut threads. Only reason I mention this is for others that may be interested. Cutting threads is a must for me. If you get a machine that can't cut threads. You will regret it at some point. Even if you don't know how right now.
If that one cuts threads then that would be a great machine choice. Especially for someone that doesn't have a lot of room to work with.
Many times you can pick up machines that are 3-phase because most folks don't want to deal with the hassle in a home shop. I have 2 phase converters and several machines that run on VFD's so I wouldn't pass on a 3-phase machine. I had a Buddy pick up a $2K bandsaw for $250.00 at an auction becuase it was 3-phase and no one wanted it. We put a static phase converter on it and it works great!

AK is right, thats a toy and way too much for it too.
Hit Cooks Machinery in New Jersey (yeah it sucks). While your in the neighborhood; head over to Fazio's. If you hit them right; (excess inventory and slow moving) your going to score. Don't forget your going to need riggers to move your shit!
x2 on not needing riggers. Also for home shop stuff good fucking luck finding riggers who want to move your shit in tight spaces for a reasonable price.

A Bridgeport is an easy move. You just un-bolt the turret and move it as two assemblies.
It'll thread metric and SAE no problem, but its a PITA. Have to swap gears and keep the feedscrew engaged and run in reverse to back out (no half nut etc). I do it but mostly I machine to size and slap a die on and power feed it.
Not bad! My 1230G is the exact same way when doing metric threads. I even have to change the gears.
If you do lots of threading a geometric die head is awesome. I got a bunch with a turret lathe i bought and its so easy, one pass and you have a perfect finished thread.
