Re: Real Bull 7x14 lathe questions?
2500 in is little I can stall my lathe at low speed easily enough. I haven't seen the new super duper version to be able to make a comparison. Sieg & RB probably use the same motors anyway, I doubt

Re: Real Bull 7x14 lathe questions?
Andy, I agree with what you say about speeds, my RB is several years old and the two ranges run to 1250 and 2500rpm approx. The torque at low speed does depend to a considerable extent to how well the

Re: Real Bull 7x14 lathe questions?
I'm sure you're right, and that it should read 50 to 1250 in Low, 100 to 2500 in High. Whether there's enough torque at the lower end of either range to be useful is perhaps questionable. I understand

Re: lathe height
The general rule for lathes and mills is the handwheels (carriage handwheel on the lathe) should be about elbow height. This is just a rule of thumb. I got a deal on two bar stools, nice black leather

Re: Real Bull 7x14 lathe questions?
Tony, the "new" verion in your second link still has a gearbox, if the statement as to spindle speed in the table below the picture is anything to go by. It says: "Spindle speed 50-2500/100-2500RPM",

Re: Real Bull 7x14 lathe questions?
I'd be slightly wary, Bob. Hitherto, Real Bull mini-lathes have all had two speed ranges with the usual hi/lo gears. Of course, it may be that they have decided to produce a version with a brushless

Tony, Do the one's with the variable drive develop as much torque at low RPM's? I guess the real question is, are they as goodor better than the lathes with the high/low? Bob
