Whats the benefits of a h.140 over a boxford aud ? thanksA 25, 50, 60, 80 and 120 if I remember correctly. Possibly a 100T.
That allows you to cut every metric pitch. Off the top of my head Using just the 50, 80 and 100, you can cut 0.8mm-4mm pitch.
Bigger I should think, aren't they a 5" centre height? A 140 is 5.5" with 24" between centres.Whats the benefits of a h.140 over a boxford aud ? thanks
I also have a 140 with the low spec gearbox. Had always thought it was simply that, a lower spec from the get go. But maybe it's a common replacement.
That's what I would like to do, get one cast.
Personally it's how I would make oneFabricated steady I made for my old concord.
There’s a very good reason why you don’t see that many four finger steadies but I’m not telling

Yes.Have you still got mine?
Needs to be dead square with rollersOn the subject of steadies and modifying or making them. As long as they're reasonably square to the ways and roughly on centre height, are they not adjustable enough to make work anyway? I used a random one with a bit of flat under it on my ml7 before I got a proper one, worked fine.
Could you use crowned rollers? Like the inner from a small pillow block bearing?Needs to be dead square with rollers
It would ruin your jobCould you use crowned rollers? Like the inner from a small pillow block bearing?

The 11" had the same gearbox too...pic of mineIts not an early 140.
140s were the very last machines in the L5A stable, they were generally had a much better specification than other L5A lathes. All of the 140s had the three lever norton gearbox and the L00 spindle.
It's definitely a 140. Only 140s had the square headstock casting.
That two speed gearbox is off an earlier L5A lathe. Which means you will have to use lots of changewheels to cut different threads.
What's possibly happened is someone has crashed the lathe when power feeding or changed gear while the machine is running. That has damaged the gearbox or the leadscrew, meaning they have had to find a replacement, and that's all they've been able to come up with.
I guess there is a possibility that the lathe was intended to be used in an training establishment or some other application where they did not want the choice of speeds and feeds being available to the operators. The gearbox on that machine is a lot stronger than the 36 speed norton.

I managed to get this Hendey for the right price. Is anyone familiar with this model?
