Hey guys . In the process of upgrading my shop/garage going to be in the market for a lathe and mill setup . Just wondering what everyone is using for the smith work ? Been looking at a few machines but im on the fence about what to buy . Im leaning towards a lathe mill combo machine with at least 36" bettween centers .thoughts ?
I'll second both to steer clear of the combo units as well as guntech's suggestion that a 1 3/8 inch spindle bore is a real sweet spot.
The combo machines are a real pain to get set up on, and are usually built out of the cheapest of the cheap makers too. It is ironic, that the guys most like to have success with a combo machine, being the guys with a LOT of different experience with odd set-ups, are about the least like to buy one, and the guys that have no experience to fall back on, end up with one, and are frustrated to no end by them. Most of the combo machines lack in the rigidity dept., as well as usually have very high lowest speeds, making threading a real adventure. Excitement like that, you don't need.
The 1 and 3/8ths spindle hole gets you in to the size of machine that will take a 5C collet, arguably the cheapest and most common ones out there. It allows you to fit all but the largest blanks through the headstock. Most of the lathes around on the market that have a through hole as large as that, will be equipped with a spindle nose that takes a cam lock or similar quick change chuck mount, rather than being threaded. D1-3, and D1-4 are fairly common, and easy to source other stuff for.
You can accomplish a LOT with just a lathe, and add a cross slide mounted vise to it and you can do some basic milling.
If you don't already have a decent drill press, get one of those before a mill. On the other hand, one of the RF-30 style mills is a really decent drill press as well as doing 'cut to a line' milling, which, honestly, is going to cover off 95 or more percent of the milling you will be doing at first.
I actually have a bunch of experience with milling on an RF-30 style mill, and they can be a really useful tool if you want a benchtop (ie: space is a bit scarce) mill. I have done a lot of milling on a milling slide, mounted on a Myford lathe as well. Neither is up to any sort of industrial standards, but they suffice with due care and attention, for occasional use.
