Vertex one would probably suit my purposes.

[Lee GouldingParticipant @leegoulding74917]

ok thanks for that any reason above the other you would choose that

[mechman48Participant @mechman48]

My choice would be…

1. Pratt Burnerd…. reputation & quality… these days?
2. Vertex… price.

I'd go Pratt, Tos, Vertex. Easier to get spares and extra jaws for the pratt now and in the future.

Fair few years since I bought anything from Vertex but all the gear I have is of at least more than adequate workshop quality outright, not just good for the money, and some rather better. If they have maintained quality standards then the Vertex should be fine.

Put a smaller, 125 mm, TOS on a SouthBend 35 years or so back and that was very good indeed. Don't know about the ordinary Pratt Bernurd but the precision 160 mm I have is pretty much beyond reproach. In a similar position to you some 20-25 years back I figured that staying out of t'pub and beans on toast for a month with meant I could stretch to the P-B precision. Still had to team it with an economy, part machined D1-4 backplate from Chester but its worked out fine. May have been a touch lucky as Chester were more focused on price than outright quality in those days.

Slightly scary to note that prices in £ are near enough the same as I paid back when I got the P-B. Nice to see that the poor quality end of the market seems to have disappeared. In those day most of the real low end offerings were little better than a well used chuck of decent provenance yet still not really affordable to the impecunious.

Might be worth looking into the width of the jaw gripping faces. My P-B precision has narrower faces than usual with standard chucks. Reduces ultimate gripping power but nicer on small work, an advantage not to be distained when one chuck has to do everything. Got a Taylor if I really need to grab something! Seems that on precision and light duty chucks, both 3 and 4 jaw, the jaws taper down further than the standard versions ending up with gripping faces around the same width as those on the next size down chuck. For 160 mm and up chucks this starts to get noticeable. My ordinary 200 mm four jaw is significantly more cumbersome due to this than its light duty companion and, in consequence, is almost never used.

[Lee GouldingParticipant @leegoulding74917]

Thanks for all the replies and a real mixed bag and i'm leaning towards the Pratt due to reputation.

[SillyOldDufferModerator @sillyoldduffer]

I'd go Vertex simply because it's the cheapest. Paying extra for unnecessary precision would dent my bank account and I never do that without reasonable cause.

I recently bought a 160mm three jaw from ARC. the whole chuck was cheaper than new jaws for my existing Pratt Bunerd chuck. The new one (I think it is a Zither) runs very true but is an awful notchy stiff action in use.

[Lee GouldingParticipant @leegoulding74917]

ok thanks for that guys

Any reason Bison is not listed.?

I have both Pratt and Bison chucks bought as new items. It pains me to say it as a 'Brit' but I personally prefer the Bison over the Pratt.

Also I thought that a 125mm chuck was the standard size on X10 series machines. – Depending upon what you are making bigger isn't always better.

[JasonBModerator @jasonb]

Bison was over budget going by previous thread unless you can find them at the price we got ours at.

[Lee GouldingParticipant @leegoulding74917]

I didn't list Bison I just thought those 3 as a comparison

[Lee GouldingParticipant @leegoulding74917]

Hi Nick

I'm only looking at 6" chucks as I was advised from the seller that a good 6" chuck would be good to replace the 5" that's on there and the chuckbthats on there doesn't have any internal Jaws and no makers stamp on it and the seller had tried different jaws to no avail

The chuck that's on even after being stripped and regressed is still very stiff

Thanks

You are correct – 125mm is the standard chuck size for an X10.

I'm greedy, so I got a 160mm for mine too

[Lee GouldingParticipant @leegoulding74917]

Hi David

What 6" chuck do you have

Hi David

Lee – you are getting too OCD lol, too many posts/threads, your memory is going – don't you remember, the 160mm D1-3 Pratt Burnerd one I mentioned the other day in one of your other threads, I got it off eBay recently for just £98 posted

[Lee GouldingParticipant @leegoulding74917]

Ah.. yes I do sorry pal got toads of stuff going on at the same time

I know you have .

Slow down, take a deep breath, concentrate on one thing at a time, you'll achieve much more than doing an impression of a catherine wheel .

[Lee GouldingParticipant @leegoulding74917]

I Know.. good advice

It's because I'm doing a full garage workshop at the same time and I'm now needing to get the lathe in place so I can finish the rest around it 👍

Price point is very good, especially for vertex given their gear isn't really cheap, normally you can expect a high price. More or less always over £100 for a set of parallels or vise or chuck etc..

My chuck is a standard HBM 5" 3 jaw, maybe sometimes it's just a case of the "lucky Winchester" (99% are useless and 1% are fantastic). But mine regularly holds a decently round bar to 0.02-0.03mm at chuck point, or 5mm out or so.

I would consider Vertex to hold a better name than HBM, mainly because they normally give you anything you buy with an inspection certificate. (hand written as well, which slightly helps in the unlikely case of a refund required, because it means someone at least had to pass their eyes over it.) 

I would also say I speak from experience with vertex whereas I've never used pratt/Bernard or a TOS device, although I have seen TOS chucks on much bigger lathes.

Exactly the same here.

Have you seen my new toy? .
