OK I've finally decided to get a quick change toolpost.. I did a small project today and relized how much time I wasted just changing tools. I have an Atlas 12" lathe and am looking at the Phase II toolposts... They have a size that says up to 12" and then also next size up is for 10" to 15". I'm wondering what one would be best.
Thanks!

The smaller one will work just fine.

I would (and did) get the larger 200 series for my 11" lathe. They hold 1/2" toolbits nicely, and will accept up to 5/8". Grizzly sells some beefier holders that are only $20.00. You will be getting more, I think I have aquired about 8 extras.

I had ordered in the larger unit for my Atlas 12". But once mounted on the lathe I thought it to be a little large. I don't think the compounds on the Atlas are stiff enough to support the large unit. I then aquired the unit for up to 12". Works well for me.

I would opt for the smaller one.

I just bought the larger Phase II (from ENCO, on sale at a good price). I'm using it on a 12" Hendey lathe which is pretty heavy duty and it works well.

I agree that the large one will probably be out of proportion on a 12" Atlas.

I got the larger size for a 13" LeBlond, then had to take it back to exchange for the smaller.

Curious. The larger one isn't very large, and it fits my 11" like a glove.

Either size will work. There are small 12" lathes and big 11" lathes. The 200ST, or BXA will be cumbersome on a 12" Atlas.
Travers has the small piston on sale for $89.00, the wedge for $217.00. The wedge is more repeatable, but not worth that much of a price difference in my opinion.

Get the largest one that fits properly. You have to measure the distance from the top surface of your compound to center height and then compare this dimension on the toolholder dimensions chart. The tollholders have a minimum thickness on the bottom to to support the bits, this plus the tool height (id est 3/8", 1/2", 3/4") cannot exceed the measure dimension. The toolpost has nothing to do with the selection process, you select the tool holders based on that dimension.
