You probably know from my regular musings that I have a Sherline Cnc lathe long bed and a universal cnc sherline mill, and I can't resist reading any posts about them.
I don't use them as much as I should do, because they are dead accurate, if I take the time to set it up, I can guarantee parts to within .01 mm shafts and external features, but on my bigger machines, (perhaps due to the way I treat them!) it's more like .05 and i'm happy with that mostly but it always amazes me to see their capabilities.
Quick note on the cnc rotary table, I have that too and it's built to a quality not seen on the other hobby indexers.
You may notice that on the demonstrations the speed is always up to the top and with carbide tooling because it tends to struggle on lower speeds on high speed steel, it does have a compensation feature on it's board but it's not enough to overcome large cuts, cuts that I could get away with on my bigger lathe, like 4mm roughing stainless steel.
They could probably do with upping their game on the motor side, it's only 1/5hp but you can get a brushless 500W motor with an ER fitting head for about £100 with variable speed. (Not to act as the spindle but simply to hold the pulleys where the other motor would normally go)The other features of the sherline machines are nigh on flawless that being said.
The older Australian sherline machines are quite rare but they were actually equipped with a small induction motor with a single/double speed settings on the pulleys, and are probably better off sticking with them. C;early the original designer, now long gone I think, intended it to give decent power output for a small machine.
The variable speed feature on the brushed standard motor gives the illusion of being able to handle larger diameters with less power, which is a nonsense to say that you could part off a 1" steel bar with 200rpm on the wee motor. Doesn't work. not unless you machined a different pulley set.
I would also praise them on the amount of literature they offer to help people understand what to do, far beyond what other machine makers are willing to offer.
