Re: what lathe to start with
I have chambered some very accurate rifles with an Atlas-Craftsman 12x36 lathe made in 1938 and weights ~ 400 pounds, and cost ~$400. Someone has replaced the Babbitt bearings with Timken bearings, and did it right.
It is slow work.
1/5 horse power is not the limitation.
The limit is the lack of stiffness.
Try to take off .010" in a cut.
Only .005" came off.
Make another cut without changing the cross feed or compound.
Only .003" comes off.
Just keep fooling with it, and an accurate and smooth cut can be made.
I put a Shilen select match barrel on a Sav99 in 6mmBR with that lathe and it shoots great.
I put a Pac Nor barrel on a Win pre 64 M70 in 270 with that lathe and it shoots great.
So why did I but a new 1200 pound lathe this year?
I am sick of messing with incremental cuts.
I am sick of the hole thorough the spindle is too small, so everything has to be done in the steady rest.
I am sick of the change gears.
-------------------------
I had a 1967 Clausing 5914 12x36 lathe that weighed 1200 pounds and had 3 hp 3 phase 440VAC that I converted to 220VAC 3 phase and ran off a converter. I paid $800 at auction.
Why did I get rid of it?
I was sick of working on it.
The tail stock ram hole was worn, so the ram was loose.
The hydraulic control on the variable speed would not stay put.
The lathe was noisy.
The cross feed and compound that complicated thrust bearing assemblies that contributed to backlash.
The foot brake stopped working years ago.

Why did I buy a new PM1236 this year?
I got quiet.
I got accurate and fast.
I got a foot brake that works.
I got DRO
