Here's what I'm looking for gentlemen, http://cgi.ebay.com/ws/eBayISAPI.dll...m=190260135121 and I'm having a rediculously difficult time finding any tool suppliers that even have a clue as to what I 'm talking about. Clearly I am not 'phrasing' my searches correctly, and I am also apparently not describing the item correctly. Please advise on:

1) Correct terminology, ("Jacobs spindle nose chuck" get's only 'deer in the headlights' looks),
2) WHERE (other than EBay) I can find someone that sells these and knows what they are,
3) Suitable substitues for "Jacobs", (all so far think I"m referring to drill chucks when I say "jacobs" and "chuck" in the same sentence),
3) Any other comments that you think might be helpfull.

Thanks,
Paul

I think the key terms you are leaving out are Rubber & Flex. I think if you described it as a "Jacobs rubber flex collet chuck for a lathe" anybody trying to sell tooling would know what you are talking about (One would hope). I would imagine MSC has them... Their website is very difficult to find anything on but they have a comprehensive inventory. Jacobs rubber flex collets are also popular in tapping heads (Tapmatic maybe others?) so that might be another way to describe them too.... "A large version of a Tapmatic rubber collet"

Are you looking for a kit of chuck and collets? Or just a replacement collet?

Good luck.

Thanks for the info and suggestions. My reply is a bit late becasue I have been on an extended trip. I'll try your suggestions. However, I spoke with someone at MSC and they could not find anything of the sort.

Thanks again,
Paul

Thanks fuzzyracing1967, but I'm looking for the chucks, not the collets.

[fuzzyracing1967]

Sorry about that gitano I thought you were looking for collets,as far as the chucks them selves I think there no longer made,(jacobs anyway),I could be wrong.There are others out there is there a reson your want the jacobs?

Are you looking for a spindle nose for 5C collets? With a D1-5 mounting plate?

This:

Or do you need larger than 1" bore? A 16C or a 3J collet nose?

It’s often very difficult to find an engineering tooling item on the internet, due to the way that search engines normally rank database type directory & editorial sites, so you are forced to troll through them in the hope that you can find what you are looking for. This is really frustrating when you are busy and need to find a supplier quickly. I got so fed up with it for my technical training courses that I created a specialist site, and every day now I am adding more and more products & technical info, videos on site. It is not a forum but I would welcome any good technical input etc. http://www.mctooling.com/index/listings/category421.htm

Based on this question and others he's asked, I think he's just looking for collets and is running down the wrong path.

Donkey Hotie, as I said in response to fuzzyracing1969, I'm NOT looking for collets, I'm looking for chucks. I'm not sure why there remains confusion about this. The initial post even provided a picture.

I'm looking for the CHUCK.

Fuzzyracing1969,

There are others out there is there a reson your want the jacobs?

Nope, and I acknowledge that what I don't know about the subject would fill volumes. If there are "better" solutions than the Jacobs chuck pictured in the first post in this thread, "I'm all ears". Grizzly provides a quick-change chuck system for the G4003G, it's 5C-based, but they want $300 plus shipping to AK. I have a friend that has a Jacobs chuck, and I "like" it. The ones I have found used run from about $100 to $400. I'm not particularly interested in paying $400 -$600 for something that I can do for $100 to $300.

Are you looking for a spindle nose for 5C collets? With a D1-5 mounting plate?

Yes... BUT... While I'm not "married" to 5C, I am "married" to the D1-5 6-pin mount or a mount that will fit a D1-5 6-pin mount like maybe the D1-5 3-pin, of which I see many. I am interested in stock larger than 1" - specifically, up to about 1.375". I appreciate the eBay citations, and I'll have a look at them.

Thanks,
Paul

PS - Do any of you responding to this thread have the center-to-center dimensions for the the D1-5 3-pin connector?

Donkey Hotie - The first item you listed above is for sale on eBay for $685 plus shipping - the second, for $775 plus shipping. I think I can accomplish my goals for less. Thanks for the citations.

Paul

[fuzzyracing1967]

Ah now I see,we have 2 of them,(yes they are nice and no there not for sale :nono

If i were you I would start looking at machine liquiddaters,they mite have some laying around from a shop that closed.That said if you find one for a good price in good condtion buy it.

The proper name is Jacobs Rubber-Flex. I have talked to Jacobs in the last year and they had one engineer there yet that knew about them. They made two sizes, one went to 1 3/8" diameter and the other went to 1" diameter (much rarer). They have not made either for years and years but show up on Ebay quite regularly. I have the larger chuck which I would sell, it would need an adaptor to go onto your machine. I don't have collets.

[gitano]

Thanks bk1955. I bought one off of eBay http://cgi.ebay.com/ws/eBayISAPI.dll...m=130267206686. $200 delivered to Alaska. I've got an adapter, $80, on order.

Thanks to all for the input,
Paul

Hello,
Just purchased a Jacobs model 92 lever chuck that fits a D1-4 and uses the 900 series collets. Does anyone have or know where I can get a parts diagram and/or owners manual?
Thanks
Murph

[bk1955]

Are you talking about the 900 series rubber flex collets?

[murphdog]

I am looking for the parts diagram/owners manual for a model 92 lever chuck.
