Agreed! That's why I say most any lathe (barring an utter wreck) is better than no lathe at all.
For a while I was looking at making a cross slide for the wood lathe(popular mechanics) just to turn things but I doubt I can get one accurate enough.
I suppose a compound vise could be clamped to the bed of a wood lathe to give controlled x and y axis movement. BUT most wood turning lathes simply do not have the mass or bearings to allow metal turning. Same as putting a compound vise on a drill press and trying to use it as a milling machine.
Speaking of wood lathes, years ago I saw a large lathe made from wood which was designed for machining metal. The beams forming the ways were capped with steel rails. Interesting machine, it had been used for real work. Apparently gun barrels had been drilled on it.
There are various plans out there for making machine tools.
If I remember correctly, I paid three hundred odd dollars for my little 618 Atlas. Small lathe, but it is useful for many jobs. Paid a lot more for my Standard Modern - but it is a capable machine.
Strangely enough, I have never even thought of trying a Lee Enfield 30/30. Might be fun to play with.
Lee Enfield builds are quite fun fer sure.
I did one Lee Enfield No.4 up in .32-40 Win as a pest bomber & plinkin' rifle along with another one in .45 ACP and they be mine till I croak.
Me LE 32-40.

Yes I have seen plans for the multi machine made from a couple engine blocks that kinda makes sense because you can have them machined flat and the bores machined true to the head. Theirs also the concrete lathe plans floating around. But these while relatively cheap(multi machine being a lathe horizontal mill and surface grinder) are finicky to get dialed in.
These days theirs not any $300 lathes south bends are over $1000.
Whoever bought the lathe that sold in the last Switzers auction for $575 plus commission and tax did well. Came with a decent amount of tooling. Made 1988. I suspect that its size may have given some folks pause. It was not at Switzers - it was at the consignor's location, and removal was up to the buyer. Might or might not have been an ordeal.
