This is kind of hard to put my thoughts into words but ill give it a go.
I currently own a Sieg X1.
Can I mount a set of 3 jaws to my Mt2 spindle . And use it like a vertical lathe I guess you can say . I have a rotary table . What else would I need an adjustable tool post ?
Is there an easier way to do this besides mounting a motor and pretty much a whole lathe set up on my bed.

Hold the tool in your vise, and your all set.
Rigging up a tool holder taller than your vise will allow you to cut a long piece. Vice mounted, or T-slot mounted, as long as it's sturdy and holds the tool tight. Simple to make out of a steel block. I've never done it, but it's been done before.
Check out this youtube video showing a mill used as a lathe

For example Ide like to take a small square piece of aluminum lets say its 1 1/2 x 1 1/3 square and reshape it to a 1in circle.
Cant I just stick it in the 3jaw get a tool holder and go to work .
I realize I cant do this with a 6in 1foot long piece of stock .
I want to make all metal gears for my X1 I figured I could do this.
knudsen thanks for the tip ill try that.
George thanks ill watch that now.
i tried this on my x3 and wasn't happy with the results...
Care to explain I cant see any difference at all. Its set up almost the same except one is vertical and the other is horizontal. Did you have the tool set correctly in the tool holder . From the way ive been thinking of it the tool wont dit the same since every thing will be flipped around.Originally Posted by Teyber12

The best way to learn is trial error.
You are probably a lot better off starting with round stock. To cut gear teeth, you probably need to make a tool that spins in the mill spindle and use a rotary table to turn the part after each tooth is cut. Actually cut a valley, then turn the gear 360/no. of valleys. The tool to make is somewhat like a fly cutter, but the cutting tool is 90 degrees to the Z axis and is ground to the profile of the gear. You can just use the old gear as a template to grind it.
You only need a $5 3/8" HSS tool blank to test the abilty to use the mill as a lathe. For short parts, as gears are, you should be able to just hold the cutter in the vise. What material are you planning to make the gears from?
You might also check stock drive and mcmaster carr for metal gears. I've never seen an x1, would it be feasible to do a belt drive conversion?
I definitely did not do it super proper. But i chucked up some 3/4" steel i had into a 3/4" r8 collet. Then i used one of the teeth of a slitting saw clamped into a 3 jaw chuck. It would not cut in but the steel would just move away, which just marred the steel. I think it would be a different story if i had made a miniature gang tooling setup like you see in the video. I guess i should have elaborated.

Probably would have worked if you used a proper lathe tool, but that is really cool how the vid has three tools mounted, especially for CNC.
Using a mill as a lathe works better than using a lathe as a mill.
It's better to make small parts on a big machine than big parts on a small machine.
On the job, you can prick your finger, but you can't finger your prick.
Floss daily, vote the straight ticket, you just might go to heaven.

I was going to use my mill to cut the teeth .
Ive never cut teeth before. This vid on youtube explains it very well.
I was going to use it.
Im not sure what metal ill use. I was going to use aluminum.
I just seen the price for a Taig Lathe wow I didnt know they were so affordable for such a great product I may buy one very soon.
