New chuck
I've been looking for a three jaw scroll chuck for the Schaublin 102 recently, and it was an interesting excercise going through comments on the web regarding brands, price, and quality.
To cut a long story short, I've just bought an 80 mm Fuerda chuck so I'm keen to see how good it is.
Quite a few comments from the USA suggest these are better than Bison these days, so it remains to be seen if it's that good.
They're Polish chucks now made in China - like many other brands.
According to the guy at General Tools where I got it, they've sold a lot to precision machinists in all sizes, and the feedback has been 100% good.
Anyone else in the group tried this brand?
General Tools were good on the deal and knocked the $130 price back to $117 when I asked, so a plug in it for them on this.

Hi Rob,
I have a 130mm front mount Fuerda for my rotary table, it is a nice chuck.
I also have a 5" chuck from ozmestore, it is crap in comparison. When moving the jaws any decent distance there are obvious tight and loose spots. I have cleaned it out but this has not seemed to help.
As far as the Rivett goes i will be trying to find some genuine chucks, these have a small L type mount. I am yet to see one for sale though. I have found some genuine 4C collets but it will take a long time to build a complete set.....

Hi Ewan,
I noticed in my travels on the web in the last day or so that there was a Rivett cross slide/ compound going on Ebay in the USA if you're interested.

He may ship if pushed.

Hi Rob,
I've got a Fuerda chuck on the rotary table, seems fine. I think you'll be happy with it.

I thought Gator was the premium Fuerda brand?
Gold, the colour of choice for the discerning person.

I've got an L-00 Pratt-Bernerd EC collet chuck I don't strictly need given I don't have a lathe with that spindle nose (and have no intention of ever buying one). What size is your Rivett?
The plan has always been to 'modify' it to fit one of my other lathes but given it hasn't happened in nearly 10 years, probably never will (and it's a pity to butcher a tool if it's avoidable). I've a D1-3 version mounted on the Chipmaster, use it all the time.

I bought a 6" Fuerda a couple of years ago and I'm happy with it. It's a 4 jaw so not a direct comparison perhaps, but the quality seems quite decent. I haven't used it enough to say anything about durability, but I would buy another Fuerda. It also came from General Tools.

I have 3 of them; a 6" semi steel upmarket one for the lathe, unused as yet bet seems good; an 8" front mount 3 jaw on a rotary table I have no complaints with and then there is the 8" 4 jaw on the lathe. What a pile of crap, loose and mismatched jaws which have tight spots and is generally roughly made.

I have two of them, a 160mm 4 jaw and a 100mm 3 jaw. The 4 jaw is not bad, but two jaws are a bit looser in the guides than I would have expected in a new chuck.
The 3 jaw works OK, but the scroll feels rougher than I expected. From memory they did not quote a maximum runout for the 100mm chuck, but they did for the larger sizes. Runout on mine is outside the figure for the next size up, but still acceptable for a 3 jaw chuck. The most irritating thing about it was that the mounting plan supplied for the chuck bore no relation to the chuck supplied - the diameter of the PCD for the mounting fasteners was incorrect, as was the fastener size. Yes, I should have checked the actual chuck before making the backplate to plan, but then I would not have three nice spare holes on the wrong PCD and wrong size in the backplate for decoration.

I just bought crap
Well Frank, you are not alone there with your quality Fuerda chuck.
The 80 mm chuck felt the same - rough.
But then it got worse. Much worse.
I faced the mounting plate with the TPG and mounted the chuck and took readings.
With a 10 mm test shaft it ran out at 0.05 mm approx 20 mm from the chuck.
So I trued the jaws by hand and got it down to 0.01 mm
Moved to dial it in at 20 mm and got a whopping 0.1 mm runout - what the...................???
During this process the scroll felt rough and notchy.
Pressed on with the 20 mm set up and, whoops, did I just feel the teeth slip? Tried again. Yep, scroll gears are jumping teeth.
Took the back off and there's so much slop in the gears and driven plate that the damn pinion gears are sticking and now jumping teeth. All in half a day.
How crappy is that?
So it's back to the supplier tomorrow for a refund.
I don't want a replacement as I have no faith in the product.
Pure crap.

A couple of years ago I had the joy of fitting five 125mm fuerda chucks to a collection of hercus 260's. The quality was variable in terms of accuracy. I tested them all with a 20mm bright rod at 50mm from the chuck face. The best (from memory) was 0.02mm and the worst was 0.14mm total runout. The others were all around 0.06mm or so. I wasnt real wrapped in them, I made great efforts to make sure the backplates ran bang on. With the really bad one, I thought I must have buggered it up, took another fine skim on the backplate and mounted the chuk in situ, didnt change a thing.
I just bought a Bison-Bial 160mm chuck for my own 260. Ive never seen more than 0.02 out of it across a range of diameters, often itll go close to bang on. Its about 6 months old now and its very very nice indeed, very rigid and repeatable. Mind you, it did cost me $550 bucks, which was more than i paid for the lathe...but it was my birthday present, so screw the haters. Ive been a lot more keen to use the lathe now that I can face and part off with confidence.

I just use a good quality 4 jaw. 3 jaw chucks are for repetition work where the workpiece is pretty much going to be machined in a single setup so slight runout doesn't matter. Bellmouthing definitely does though.
If I want runout less than 0.01mm and the work diameter is less than 40mm I use a collet. Over that, a 4 jaw. The 3 jaw chucks I just use for rough work. I even have one P-B chuck with a set of 'soft' jaws welded to the original jaws - just skim it or bore to diameter as required.
Yes, I'm a metal butcher.
Having said that I'm not knocking you for buying a good 3 jaw chuck. I just prefer to buy good 4 jaw ones myself as they can *always* be set to have the workpiece run concentric (or offset if required) and they hold a lot more rigidly than any 3 jaw chuck ever made which makes parting off & facing much less problematic. I just don't use a 3 jaw enough to warrant spending serious money on one.

Rob,
At one time Schaublin supplied Reishauer chucks along with those made by Pratt Burnerd, for their lathes. The dividing head on my mill came equipped with a 4 inch 3 jaw Burnerd chuck. The DH's spindle nose thread matches that of the 102.
Here's a cheap used Reishhauer - http://www.ebay.com/itm/Reishauer-Ba...-/321323685319
And here's a not so cheap tiny version for a 70 lathe. http://www.ebay.com/itm/Schaublin-70...item19e8d7b4cf
Occasionally, Burnerd chucks appear on eBay in reasonable nick at reasonable prices. I bought an 80mm 3 jaw Griptru for about a hundred bucks 5 or so years ago though in all honesty I reckon a 4 jaw is easier to use .
Bob.
