Just a few quid more would get you a Pratt from Rotagrip

[Lee GouldingParticipant @leegoulding74917]

Hi Jason

Thats only a 125mm.. but thanks for the reply

Cost wise you might be better looking for a chuck and backplate

[Lee GouldingParticipant @leegoulding74917]

Hi John

I'm a new lathe owner and not sure what you mean Chuck and Backplate as i already have a 6" camlock back plate?

I just assumed that i needed a D1-3 camlock chuck to fit..

Thanks

[John Stevenson 1Participant @johnstevenson1]

Some chucks are just chucks with tapped holes on the back so they can fit anything.
Some come with a backplate of choice already fitted and some have the D1-3 fitting machined as part of the chuck.
Cost wise I have mentioned them in order of cheapness.

Edit just read all your post and if you have the backplate then you have the D1-3 fitting. All you need is a generic 160 mm chuck to bolt onto it.

Another option is to buy secondhand.

A couple of months ago I bought off eBay a 160mm Pratt Burnerd 3 jaw chuck, nice condition, D1-3 camlock backplate already fitted, for £98 delivered!

[JasonBModerator @jasonb]

oops, 160mm is about £350 from same source

[Lee GouldingParticipant @leegoulding74917]

HI John

So if i went with a standard chuck i would just need a new backplate and that would fit fine on the spindle nose?

Is the spindle nose specific to the lathe.. i have the boxford 280

Thanks

[Lee GouldingParticipant @leegoulding74917]

Hi David

I have been looking for one but none available at the mo..

Thanks

I think Jason meant this link :   http://www.rotagriponline.com/index.php?page=shop.product_details&product_id=3534&flypage=flypage-ask.tpl&pop=0&option=com_virtuemart&Itemid=29 

160 mm standard accuracy Pratt Burnerd for £ 351.90. Safe to 3000 rpm which is nice. No specifications as to axial alignment, concentricity and run out tho'. Its an import of course but probably more of a warm cuddly feeling from buying via a major industrial supplier. Hafta say there was an moderately minor issue with the new PB chuck I got back in the day and that was sorted with no quibbles. Chucks'R Us shop types wouldn't have wanted to know.

With an integrated fitting chuck these need to be good out of the box as there is no possibility of adjusting thing. Theoretically a backplate fitting can be adjusted to compensate for any chuck body errors. Monumental faff if you want to get to thou' and below levels. Oft talked about but I wonder how many people have actually done it. Considerably different than getting better results from a 40 year old worn out chuck.

In a practical world its the axial alignment with the spindle that really matters and that is something readily got dead right with a backplate.

In todays market pretty much all but the stupidly cheap stuff has generally acceptable performance so there is much merit it Johns suggestion of getting a reasonable, but relatively inexpensive chuck and backplate. Maybe save £100 over a respectable integrated fitting version. But if you go for brand name equipment Pratt Burnerd / Bison / TOS et al chuck and backplate will come out more than an same chuck on an integrated fitting.

Hi Clive

Great explanation and the 6" backplate i already have came with the lathe and ive not used it yet so would you say its best to get a new backplate and chuck together or try and use that backplate with a new D1-3 chuck

Thanks

[Lee GouldingParticipant @leegoulding74917]

also if any of you fancy a look at a lathe and advise then i live nr Wigan and the kettles on..

Lee

The D1-3 nose is specific to the 280 (I have a 280).

Any D1-3 backplate will fit the 280 nose.

Sorry, I probably got the last one that came up . I haven't seen another since.

[Lee GouldingParticipant @leegoulding74917]

Thanks David thanks for that

You may be able also to advise on the Mesh/Delta wiring im about to look at.. I have just got an Inverter and Pendent and need to put wire the motor to work single phase

Any idea about the wiring sequence

Thanks

[JasonBModerator @jasonb]

What other chucks do you have if any? If the 3-jaw is going to be teh first one you buy then sooner rather than later you will also want a 4-jaw. Best do the sums to see what works out best either save the backplate for a 4-jaw, or use it now for a 3-jaw. It is not practical to swap chucks onto one backplate regularly so you really need a backplate for each chuck or chucks with integral mounts

Without shopping around I think it may work out most economic to save the backplate you have for say a zither or other reasonable quality imported 4-jaw. Then get a 3-jaw with integral D1-3.

One think to be aware of is the backplate you have may be fully premachined and have a short spigot on it of about 125mm, your new 160mm chuck will need a matching recess to suit this spigot.

Nick_G may have posted about fitting an inverter to his Similar Boxford.

It's really your choice, which will probably be dictated by a mix of cost, availability, and the amount of faffing involved.

If I weren't dictated by cost I would go for a new Bison with D1-3 backplate as linked above.

[Lee GouldingParticipant @leegoulding74917]

HI Jason

It came with the lathe and its a 5" 3Jaw D1-3 but the jaws are external so need some internal jaws for that but don't know what make it is as the lathe only came last night.. i have took it off but the had to leave it till tonight to look at

I was advised to just get a bigger chuck and a new one

Thanks

Boxford fitted three or four different motors. I presume you checked the motor plate first, as you may well have a dual voltage 240/415v motor.

[Lee GouldingParticipant @leegoulding74917]

How do i search for Nick_G and his post

Thanks

[Clive FosterParticipant @clivefoster55965]

Lee

Use your backplate unless the stud thread alignment is so poor that any of the cam position indicators are outside the 45° quarter past / half past safe fitting arc. Very rare error. As mentioned on another post I have a backplate that is marginal and can only safely be used in one position. PB precision 160 mm sitting on it and all behaves just fine.

If you are going to use your backplate then have a look at this page **LINK**. for ideas.

The Vertex at £180 looks a deal but not sure how well Vertex quality has held up over the years. All my Vertex gear has been at least outright good not just good for the price. Bought a new 125 mm version of the TOS front and rear mount chuck years ago for a SouthBend lathe now long gone and was perfectly satisfied with its performance. Not far short of my 160 mm P-B precision really.

Clive.

[Lee GouldingParticipant @leegoulding74917]

David

Yes its the dual voltage one
