Suggestions for a good ind 100mm 4 jaw for mini lathe

[PackmuleParticipant @packmule]

Has anyone any suggestions for a good quality 4 jaw ?

Had done from a supplier but now 1 jaw no longer grips so not looking for more rubbish just one that does what its supposed to.

After talking to supplier of faulty one I got nowhere will never use for tooling again.

Thanks Bob

If you can find one … The Burnerd 'front fixing' 4" is a nice little chuck.

What is your budget, what mount is it, can you face off a backplate, or does it have to come ready to put on your lathe?

Who was the supplier? So we can all avoid…

[SillyOldDufferModerator @sillyoldduffer]

Crumbs! Hard to imagine breaking one. Sounds as if you were unlucky with a manufacturing defect. Any chance of a photo of the dismantled criminal?

My gripe with cheapo 4-jaws is not that they break, it's that their adjustment is 'gritty' rather than smooth. They do the job but take longer to set up.

Yep, Burnerd 4" four jaw is hard to beat. Loads on the second hand market.

Did you try arc eurotrade ? They sell genuine sieg stuff that will fit your lathe and comes from one of the few good factories in china . I suspect you will have to make an adapter for a burnerd to fit a mini lathe .

Yes, that was my assumption when I suggested the front-fixing Burnerd … it would need a simple backplate.

TOS and Bison are also good quality but they do cost more than budget brands. As usual with budget equipment we rely on the supplier to back the products they sell and to have chosen a manufacturer that makes a reasonable quality at a keen price, if price is too much of a priority then quality will suffer.

Try Rotagrip I have bought lathe chucks from them at the better end of the market and found them to be very good. They are also knowledgable and helpful. No connection just a satisfied customer

I haven't tried a Zither 4-jaw but their 100mm 3-jaw is exceptionally good for the price.

A good brand if you want a balance of cost and quality (ISO9001).

I bought a Fuerda 100mm chuck 2 years ago, and have had no problems with it.

Thanks for your kind comments. I would just like to clarify please, which I hope no one will mind…

The Chinese lathe chucks we sell are purchased through SIEG. If we have a problem, we sort it out with SIEG. In turn, they sort it out with the manufacturer. Having said this, there was a batch we had re-called, and this was posted on this forum at the time. Other then that, we get the odd faulty chuck, or a return where the customer is not happy with the chuck, even though the chuck is fine – no better or worse than the average Chinese chuck.

Having said the above, most Chinese chucks are fit for the purpose they are made for, provided they are procured through the right channels. The Zither chucks from India are better than the general Chinese ones, but you will need a plain backplate, to be turned on your mini-lathe for the register, then drilled and tapped by you to make the chuck fit. Again, one has to be careful without making presumptions that all Indian chucks are good. SHARP – Indian chucks from Chronos are also good. In all such cases, a backplate will need to be used.

Ketan at ARC.

Thanks everyone for your replies.

The chuck was from Gloster. Its about 2 years old but has only been used half a doz times . the screw thread will close 3 jaws but the other you can slide shut. It was budget price so you do get what you pay for but still works out expensive when its hardly been used.

Looks like a trip to see Ketan at Syston as its only 10mins away.

I also bought a fuerda 4 jaw self centring chuck last year and very pleased with the quality of it.

Packmule,

Have you investigated repairing your chuck? In an independent 4 jaw there are retainers that keep the adjusting screw from moving axially. It seems that is what failed on your chuck. Some Asian 4 jaw chucks have rather flimsy retainers.

The name brand chucks listed in other posts are all good.

[Raymond AndersonParticipant @raymondanderson34407]

Bison Bail 3704 for 4 jaw SC, or 4306 for 4 jaw independent Both will fit your mini lathe. The 3704 is mounted on an adaptor plate from the rear, and the 4306 mounts from the front on to the adaptor plate.

Hope this helps.

[not done it yetParticipant @notdoneityet]

Packmule,

I note from your original post that you apparently ordered a good make initially. Did you choose the cheapest of a range of qualities available from the various suppliers?

Further, it would appear (to m3) that it is likely a 4 jaw self centering chuck (you say 'the screw thread will close three jaws&#39? These, IMO, are only good for perfectly round or square (or octagonal) items. With any deviation from the above, one pair of jaws will tighten before the other, which could cause problems. Buying the bottom of the range is not always a good decision I'm afraid. I try to avoid that scenario, but have been caught out by banggood recently.

If the chuck is a scroll type, it would appear that the jaw is at fault, not the scroll. Can you confirm exactly the type of 4 jaw you bought originally, please.

[PackmuleParticipant @packmule]

Hi Not done it yet,

It is not a scroll type and as suggested by John I'll have a look at either shaving some off the retainer or making a new one before I launch it to the bin.

I have taken it apart and measured the chuck and the jaws and there is a discrepancy between them (no 2 are the same never mind all 4 ) so perhaps a little time spent playing before biting the bullet and replacing . It s very rare I use this chuck hence where I said its only been used a few times .Normally use a collet chuck of 3 jaw.

Bob

[Perko7Participant @perko7]

If the jaws are undamaged and the adjusting screw is the faulty bit you could make new ones. I had an 80-year old Burnerd 4-jaw independent in which one of the adjusting screws broke at the waist where it engaged with the fingers on the jaw. Some careful measurement indicated the screw threads were 1/2" BSW so some suitable length BSW set screws (sometimes called grub screws) were purchased, a waist machined on them to suit the jaws and all 4 adjusting screws replaced. Now works beautifully.
