Thread: Lathe backplate chuck help
06/12/2016 11:36:04
Posted by Christine Walker on 06/12/2016 11:10:56:

Thanks for all your replies. Unfortunately, any machining is a little beyond my capabilities at this point, I am pretty new to all this (as you can probably tell by my questions!)

It has just been suggested to me that 39x4mm could possible be 1 1/2 x 6 TPI... thoughts? Or anyone know of a way I can check this please?

Thanks again


No, it's close but not interchangeable.

chester sell them at £50 quite expensive though i`m confused why they state they are for the 920 lathe but are listed at M40x 4mm????

They are $23.95 at LMS in US. Usual rip off Britain I'm afraid.

If those at Chester really are 40x4mm they won't fit.

I'm surprised you didn't get a 4 jaw independent chuck with the lathe. One was originally supplied with mine.

I'm in Gloucester and you be welcome to borrow one of mine.

I have same lathe and had the same problem.

Little Machine Shop in the US has what you need, both 4" and 6" versions **LINK**

They are happy to post to UK - not cheap though.

"The 3m adhesive can be removed without leaving a residue when you are finished with the mount."

I had a Makita 18v with a chuck that would not come off despite all attempts. 3 people tried and 3 failed. I ended up cutting and grinding the old chuck off piece by piece.

Turn a shouldered plug to fit in the tailstock end.

Thread: Taps
25/10/2016 20:47:57

I have not used any always stuck to good HSS taps.

Not sure if these are the same as you mention but, gleaned from the web.....

NOTICE ON USAGE. UH-CT cannot be used by hand, it must be used by machine; machines with feed-rate/rotation synchronized tapping mechanism are recommended, the maximum rigidity of tap and workpiece holder is recommended, drilled hole must be as large as possible.

We could put the lot on a single DVD.

Would people be prepared to pay around £50 if it was nicely presented (proper case, colour inserts and cellophane wrap), and included some sort of index?


I would if the DVD contained all issues from number one to the present.

I have been known to plan the sequence of machining operations but I sometimes wonder if that is going too far.

Absolutely not, it's just plain common sense. wink 2 It prevents cockups where you end up with no way to hold the work for an operation. Planning is especially useful for awkward shaped castings, or where certain features need proper alignment. I spend a lot of time working out the sequence of machining and making jigs that may be needed. Ideally the job then goes quickly and smoothly.


I don't do much in the way of drawn plans, just enough to keep me on track, but I've learnt the hard way to think through carefully the order in which I will make something and which bits really have to be accurate.
