Colin you are assuming I live on a normal street

My power comes in on over head cables, they wanted to run a new over head cable for about 500m, add some new "telegraph" posts and charge me for an uprade to the local transformer

Backplate or drive plate

Catch plate, a little something he is missing.

He has also been offered a back plate but it come attached to a second 3 jaw chuck

I suppose you could accept the backplate and assuming there is enough metal recut the register if needed for one of your favorite chucks, assuming the one already on it is not upto scratch and sell on the chuck using the money to treat him to other goodies.

With his 11" swing do you see yourself using him for most of your work and just the very large stuff on the colchester or might you want to keep cast iron swarf away from his shiny bits?

They are both OEM chucks so I doubt that the register will need re-cutting

I am told he comes with a very nice 3 jaw chuck and I have a brand new one already, so that is the necessary two three jaws

Having used one of his contemporaries I suspect that I will not want to use any of the other lathes but I will probably stick to the current practise of very large/long stuff on the Colchester and every day work on my new friend

Is that to save having to change jaws? if it is won't you want a third for the soft jaws?

Jo · « **Reply #50 on:** April 21, 2015, 07:54:42 PM »

Actually I found someone who has 5 brand new packets of soft jaws for them

It would take a long time to get through 5 sets you you should be OK for a while

Add a few stepped 5C collets and you should have all options covered.

Jo,

I should have known better. I'm sure the neighbours would have appreciated a power upgrade.

A 5C stepped chuck to use their correct name

are good but not if your collet holder relies on the taper on the little 5C collet to close it

Each size of stepped chuck has a special closer that fits to the nose of the lathe to close it for accurate work holding

.

For those of you who have not used step chucks they are designed to take over above the diameter of normal collets: you bore them out like soft jaws but like a collet they do not grip on three places but all the way around and the stepped chuck closers ensure that even with the largest 6" the gripping pressure is evenly applied on the outside of the chuck over the stepped area of the chuck

Thanks for adding the photos, it's all become clear now. I can see how the taper on the outside will provide much more closing force than the usual small 5C one

Jo · « **Reply #55 on:** April 22, 2015, 09:23:16 AM »

There are a couple of other interesting 5C "fittings" that they do like:

5C Plug Chuck: a blank 5C for machining arbors.

5C Taper Hole collet: a hardened collet with No 1 or No 2 morse taper or the alternative Brown and Sharpe tapers.

I'm becoming a tool bore: I must try and get out to make some swarf

Thanks Stuart, I am getting worried that if he moves in that he is likely to try taking over my workshop
