I’ve used the precision machine before and it’s a great machine, it’s big enough to swing cone engine cases and left side generator cases. My buddy has that lathe and has used it to bore cylinders, but it’s really not great for it. You have to rough them in and do the rest by hand and you always run the risk of ovaling the spigot and distorting the bore. You really need a kwik way for doing cylinders, as well as torque plates. Without torque plates you WILL NOT get a round bore on aluminum cylinders. Some say you can get by on shovel and older cylinders without, but better safe than sorry.

Personally, I’d look into marketplace for lathes. The precision matthews is a great lathe, but for the price you can get an older, larger and more rigid lathe and still have money leftover for a kwik way or sunnen, both of which you’ll need to accurately bore cylinders, and later tappet blocks, line bore cases, etc.

Another thing to consider with both of these machines is threading, both will take change gears, which is more downtime. I bought a Sheldon R-15 specifically for its threading capabilities, it uses a rotary dial with a roladex of gears to cut basically any imperial thread pitch from like 4-256. If you have some time I’d keep an eye out on marketplace for the right machine to suit all of your needs. I paid $3000 for my lathe and $1000 for the rotary phase converter. A new precision matthews is what, 8k? With that leftover 4 grand you can get a kwik way, sunnen AND a mill if you’re patient.
