Thread: Myford ML10 lives again

Hi Dave, nice job you did there.
Couldn't see any remote Stop in case you get caught up in the chuck or belt, perhaps it's at knee height ?

Emgee

Hi Emgee, Yes a bit of an oversight on my part, I have no tooling for the lathe yet and would like a quick change toolpost so while I save some pennies for these items I have ordered an emergency stop button and will fix to the front of the bench before I start to use the Lathe.

Well at long last it's finished and running again. I'm really pleased with it and have enjoyed the strip and clean up. I had a problem with the electrics but thanks to the help and advice from a forum member David (AKA Myford boy) I got it sorted. Thanks again David !

Thread: Motor Gland

Motor threads are "usually" 3/4" Condiut. 750" o.d. x 16 threads per inch, These are NOT BSP.

Condiut is designated by the Outside Diameter.

BSP threads are designated by the nominal bore of the pipe.

Regards,

Alistair.

Thanks Alistair yes

Hi, it's not M20 that's for sure, I've tried it. Its an old Crompton Parkinson motor of unknown age. I suspect its imperial and everything I've looked up is metric. Can't seem to find a stockist of imperial fittings. I know its not really important but would have liked to get the proper fitting gland if at all possible.

Hi, I'm trying to locate a Gland that fits this hole and thread, rather than just jam a plastic one in there. Anyone got any idea's as to if they are available from anywhere? I'm having no luck locating one at all.

I hear what your saying but I think that's way beyond my skill set thumbs up

Only for the moment. Very soon you will be suitably qualified in the black arts. Then your workshop will be embarrassed by your uncontrollable ambition to cut metal in ever more demanding ways. I started with a Mini-lathe, now I want the biggest Dean, Smith & Grace, a steam hammer, and a Foundry...

Hi all well I went for the slim body 12mm chuck from Rotagrip. It looks really nice and is very solid, I've taken a couple of pictures for those that wanted to see the back.

Hi I only have a little Myford ML10, it only has a 3, 5/16 (84mm) center height and the original 4 jaw option was only 4" so I thought it may be an ideal choice.

It very likely is. Don't forget that when actually holding something in the chuck, the jaws may (will) extend out past the chuck body and it is that which will limit the maximum size of chuck you can use rather than the chuck diameter per-se. (Or, conversely, the maximum size of part you can hold in the chuck.)

I had thought about that which is why I was leaning towards the smaller diameter chuck.

This is the other one I was looking at from RDG tools and only slightly bigger in diameter but has a beefier body.

I notice the words 'Light Duty' in the description and see the body is only 1 1/8" thick, ie it's on the small side and not a bruiser. Slim chucks can be very handy but I'd prefer something a bit heavier for general purpose use. Depends what you're going to do with the lathe but beware! The usual experience is to plan lots of small work and then find yourself making traction engines...

Is it perhaps a little on the small side, particularly if it is to be the only four jaw available?

Otherwise seems a good choice.

HI looking around at different options for a 4 Jaw chuck for my ML10 and came across this one from Rotagrip seems to be a great price any one got any opinions on this chuck ?

Thread: Collet Chuck or not ?

Thank you all very much for all your input, loads of information for me to take in. This really is a great forum !

The Minnie in my avitar was done on the lathe and any milling cutters held in the 3-jaw, seemed to work OK for me back then.

I'm sure MT collets were used a lot in the past to hold tooling.

How big is your 20mm steel? can it not me held in the 4-jaw to true it up.

Hi Jason, I don't yet have a 4 jaw chuck but it's on the list when funds allow. The piece of steel is 60mm x80mmx 20mm.

Edited By Dave Springate on 26/03/2019 11:21:29

Wow, how quick was that. Thank you all very much that has shed some light on the subject. Now if I wanted to true up the edge of a piece of 20mm steel would a cutter slightly wider than 20mm be the preffered way to go so that a full width cut is taken in a single pass?

Also would a two or 4 flute cutter be used for this operation.

There is nothing g wrong with the Dewhurest drum that I have. I've stripped and cleaned it, repainted it and intend to make a new pointer / handle for it. I will not be fitting it, though I will be keeping it with the lathe incase I want to use it in the future.

Thread: Collet Chuck or not ?
26/03/2019 07:07:24

Hi all, as a novice is it ok to hold a milling cutter in a 3 jaw chuck for basic milling operations or should I get a collet chuck ? If I go for a collet chuck how do you choose a size ie : ER25, ER32, ER40 Or some other size ? I understand that the collet needed is the size of the item to be held but why buy An ER25 over say an ER32 or ER40 Thanks
