Thanks guys...

Hi, I have a Warco 250 lathe which comes fitted with a 5”..125mm chuck..A friend has a nice Pratt 6” chuck that he no longer uses....would this be too big for my Warco?

Thread: Jacobs arbor marking

RDG sell these together....

The problem remains that these days that if it’s not direct from the manufacturer, there’s no proof of its authenticity...

27/02/2019 13:04:47

Totally agree..but..if someone is selling a named wouldn’t be happy if you received a fake...

..Wattage is quite important depending on what you intend using it for...the small wattage fancy ones with lights etc are ok for light duty jobs but will soon stall with very little pressure...

i have. 450watt SeLey BG150w/90....About £80......I’ve fitted an adapter on the right hand side that has a half inch chuck screwed on the end..This accepts small wire brushes os different size and shapes...which I ipyse for rust removal and thread’s also good for holding small round objects that need to be cleaned or polished..

it does most things I need but even at 450 is not that difficult to stall....that’s why I think buying the smaller models is wasting money...

Thread: Jacobs arbor marking
26/02/2019 19:30:37

That’s the seller I bought it from....He said he’s been trading for 15 years and that Jacobs stopped putting their name some time ago...which they have confirmed....I asked why he didn’t send it in the container shown in the picture...he replied that he bins them as it increases postage costs...🤔

26/02/2019 19:22:19

No mention right now as my lathe is presently out of action waiting for a couple of new parts....and I bought a second hand Albrecht chuck that requires this arbor....

As I mentioned earlier Jacobs have confirmed that they stopped putting their name on in I now have no reason to doubt it’s authenticity.....but as soon as it’s up and running...I’ll be back..

25/02/2019 19:47:02

Just received a reply from Jacobs...that was quick!.....They stopped putting their name on in 2012...

seems really silly can you tell if it’s one of theirs? But I guess their name is just as easy to fake as anything else..

Maybe Rohm have done the same...anything to reduce cost probably..

25/02/2019 19:39:07 yours a recent new purchase ?

25/02/2019 19:36:31

Funny you should reply with that information...I also looked at the Rhom equivalent before buying the Jacobs..

25/02/2019 19:32:43

Exactly...maybe they’ve contracted out their production ....let’s see if I get a reply

25/02/2019 18:53:32

I couldn’t find Jacobs’s details... but after more searching I’ve now sent them an email...I will update when/ if I get a reply.....

JacobsHi, I’ve just bought a Jacobs arbor, MT2..JT1...It was sold by a reputable dealer on EBay as a genuine Jacobs...It showed a Jacobs container tube and an arbor with some writing on it...

It arrived today....but all that was stamped on it was ...MT2 JT1.... No Jacobs name, and No Jacobs container, just a plastic bag with Jacobs written on it in permanent marker...

I have various other Jacobs arbors all having their name stamped or written on them..

i contacted the seller who assured me it was a genuine Jacobs and that that Jacobs hadn’t put their name on them for some years...and that he’d been trading for 15 years....he said he put the containers in the bin because they caused extra postage charges..

How can I tell if it’s genuine or a cheap copy?...It’s a small thing but with so many fake items in circulation I thought I’d investigate...thinking of contacting Jacobs..

Thread: Warco WM250 back issues
28/12/2018 18:42:34

I think it is made with a sloppy fit on purpose...this gives enough all round play to enable accurate cantering...there are a few vids on YouTube showing how to do it...simple but effective...If it’s not possible using this method...removing the chuck and turning it 60 degrees and refitting etc to see which position gives the best reading.....if that doesn’t result in a good reading..sometimes removing the jaws and trying them in a different sequence may help...
