Re: Mounting PVC Fitting for Boring
Turn the jaws around first . Then I would drill a hole through the 90
centers with one of the openings & run a piece of all thread or a long

Mounting PVC Fitting for Boring
I've got a 70's era radial arm saw with a dust collection port that doesn't match current vacuum fittings.? I bored one end of a 1 1/4" PVC coupling to fit the saw outlet and the other end to fit the

Re: Motor Cuts using Steady Rest
It’s a LMS 4100 upgraded to a 16” bed - it has a brushless motor. I know it has an over-current cut-off and that’s what’s kicking in. What I can’t figure is why I’m might be over-feeding

Re: Motor Cuts using Steady Rest
Is it only when using a steady rest that this happens? You probably need to
check the amps.

Motor Cuts using Steady Rest
The motor on my LMS 7x16 cuts out turning down 360 brass when using a steady rest with a HSS tool. The 7" 1.25" brass rod is centered in my 4-jaw cuck to 0.005" and the Steady Rest is 2.25" back from

Re: CJ0618 lead screw
The problem with cutting threads of a system different from the lead screw is that the gears can't be disengaged & re-engaged in the same position. You have to keep them engaged the whole time and

I still have my 20-year-old mini lathe and it is just fine the way it came.

Re: CJ0618 lead screw
Pierre, I believe both versions of the lathe use module 1 gears. And I think they are sold with same set of nylon gears. But I could be wrong about that.
I have done some single point threading on

Re: CJ0618 lead screw
With my metric lathe I got the imperial 16 TPI leadscrew and half nuts, I don’t recall getting a spare apron so I don’t think that’s a problem.
I’ve only had to cut a few imperial threads,

Re: CJ0618 lead screw
Wasn't thinking about that but st a minimum I'm pretty sure you're going to have to swap the half nut actuator shaft and maybe the apron. The nuts use a different engagement to the shaft and I don't

Re: CJ0618 lead screw
Grizzly has them for their 7x14 which is like the Real Bull. The part number is P0765129 and lists for $53.50. You would also need to change the half nuts. The part number is P0765075 and lists for

Re: CJ0618 lead screw
Hi Thomas,
If you want to replace a metric lead screw by an imperial one,
the pinion sets, as per the threading table of your lathe, will
need to be modified. This is mandatory
