D1-3 compatibility

[Michael GilliganParticipant @michaelgilligan61133]

CamLock, or is there an alternative ? …

[Michael GilliganParticipant @michaelgilligan61133]

Can anyone please tell me the most compact lathe which would accept a D1-3 chuck? … either a proper CamLock fitting, or is there an alternative that keeps the big tapered nose, but replaces the lock-pins with bolts ??

Thanks

I doubt there are any "compact" lathes that have a D1-3 headstock. What are you trying to achieve?

I know the Harrison M250 has a D1-3 headstock and this range of Boxfords does **LINK**

I suppose it depends upon your definition of 'compact'.? I have one of those Boxfords which for model engineering could not be considered compact. But a friend of mine who runs a machine shop considers it to be a baby lathe.

chipmaster ?

[JasonBModerator @jasonb]

The 7 & 8 series Emco lathes have a tapered nose but use studs and nuts rather than cams if its the short taper fitting you are after.

Prazimat also has the short taper but a keyhole type flange which just needs the nuts nipping up

Bob,

What I am trying to achieve, is the use of a Burnerd MultiSze Collet Chuch [which I already own] in the small space which I have available.

If I had the space, I would probably just buy a Chipmaster, or a Kerry [both of which I have used and liked], but I do not have the space, and I only need a small "working envelope" … i.e. I don't want, or need a big machine, but I do want to use this chuck.

P.S. … I may consider buying just a headstock, and building a "Bitza"

John,

That would probably be my first choice, but I don't have the space.

Thanks

Thanks, Jason

I will investigate.

Just saw your other post, its a different taper so no use to you

Thanks, Nick

I think I've covered "compact" in my reply to Bob. … If it would just clear the Chuck body, and take [say] 12" between the face of the collet and a tailstock centre; that would be plenty big enough.

MichaelG. … [just looking for inspiration]

Thanks anyway.

[Bob Brown 1Participant @bobbrown1]

I think you best bet may be to make up an adapter plate that once you remove the locking pins allows the chuck to be mounted/bolted on one of the compact lathe back plates, blanks are cheap enough.

Details of the D3-1 mount is here **LINK**

Sorry, Bob, but that is not what I want.

I want a proper headstock spindle in big bearings, that is made to the appropriate level of precision.

How much space are we talking about?

Surely a bit like finding a crutch in the gutter and breaking your leg so as to make full use of it ?

[Old SchoolParticipant @oldschool]

Myford 254 but not really a compact

[JasonBModerator @jasonb]

A Bantam probably has a slightly smaller footprint than a chipmaster as the stand goes straight down rather than flaring out

Bob,

Space is at an absolute premium… which is why I specifically asked regarding "the most compact lathe which would accept a D1-3 chuck"

This chuck has lain unused for over twenty years and [prompted by my discussions with Nick, on another thread], I have finally decided to find a way of using it.

I get the blame for everything.!!!!

Why should here be any different.?

Quite possibly, John

… or maybe like making a Buell because you had a Harley Davidson engine available?

[feel free to subsitute other engine/frame combinations according to taste]

[Michael GilliganParticipant @michaelgilligan61133]

Nick,

You were the spark of inspiration to get on and do something with my chuck !!

Very positive … at least, I thought so until I started this thread.

I used to have a Boxford BUD that had a Burnerd lever-operated Multisize collet chuck. I replaced the lathe with one that has a D1-3 spindle, but kept the collet chuck that, alas, no longer fits.

If you have a D1-3 collet chuck and need one that fits a Boxford AUD, BUD, or CUD, then maybe we can trade?

[Bob Brown 1Participant @bobbrown1]

I did not read the original question correctly, so I would think a short bed 20" Colchester Bantam or a Harrison M250 is probably going to be the smallest.

Hi Michael

My Lathe a Heidenreich and Harbeck 20Ro uses a Din 55027/5 spindle nose. This is basically the same as a Din 55029 (D1) spindle nose but the chuck has studs with nuts that attach through keyholes in a rotating bayonet ring instead of the cams on a D1.

This link may come in handy for you.
