Most the ones the members here can afford have no electronics But the hand crank days are over so we have electric motors

So, basically the motors have to be of high horse power (5 HP maybe)? What would be the advantage of having a big lathe as compared to a small hobby lathe, something like a 7X14? Would having a bigger one mean that you could grow into it?

Thanks
Tim

I can see that I am going to have to start putting some money back for a lathe. It wont be much to begin with, but I will eventually end up with one. There is so much you can do with a lathe and I want one.

Thanks
Tim

Having a lathe is better than No lathe. but you don't want too buy twice.
if you have time then save and buy bigger.

There is just a few of the smaller Import lathes that have electronic controllers for the motor.

issue with smaller lathes is the diameter of the spindle through hole, the bigger the hole the better.


issue with very short beds, drilling holes at the parts end.
length of the drill bit + length of the lathe chuck + length of the drill chuck, and that 14" between centers gets short when drilling..

Without a large enough through hole the part can extend to the point of not being able to drill the end.

For the fix it guy metric AND US threading is a must which puts you into the Imports......

no not so much for most, just making bushings and pins.....

A mill will get more use. if not milling, just for using as a drill press.
but if you need a lathe you need a lathe....


Its more of a question which one first?

How about something to this effect? Could this possibly meet my machining needs?

Thanks
Tim

And then there are lathes without any ways....that you can see.

When looking at machinery, don't forget to "look outside the box"

But the terminology will always be the same.
Ways, tailstock, cross slide, tool holders, turning capacity (dia.) and length, etc.

That thing is a behemoth! Do they get much larger than that?

Thanks

The overall size might be large, but that machine has a 2 1/4" bar capacity.
With a chuck IIRC it would swing 12".

That is a W&S 2ab, and they made them up to a 4ab with 6" bar capacity,
which doesn't sound like much, but the #4 with a chuck instead, would swing
30" diameter.

The main point is this:
Manual lathe, turret lathe, automatic lathe, vertical lathe (Bullard)
multi spindle lathe, CNC lathe, all use the same way of
presenting the tools to the work.
1. Turning
2. Facing.
3. Boring
Etc.
