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

seems really silly ...how 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..

David...is yours a recent new purchase ?

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

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

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..

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...

Thanks Howard..👍

Thank you...very helpful..👍

Thanks ...very helpful..

Thanks again...

Im looking at getting a collet set for my recently aquired Warco WM250 lathe..

This is new to me...can anyone tell me the useage difference between ER and 5C collets...also the advantages/disadvantages of each one..Cheers..

Thanks Robbo...you’ve answered part of my question...the other screws I meant are the cheese headed ones that hold the threaded bracket...are they 3BA?...Cheers

Thanks guys...you’ve answered my question...👍

....i have recently bought a second hand Warco WM250 lathe in excellent condition...hardly used..The headstock spindle in MT4....I’m thinking about getting an ER40 MT4 collet Chuck as a direct fit for more accurate work. Would this be a good idea?...Thanks...

can anyone confirm the thread size of the gib screws on an imperial Myford vertical slide...I think they are 2ba...... Also the size of the two cheese head screws on the top of the slide...

Thanks...

Thanks for the link Vic..👍

Please could you tell me which Grizzley model..is the equivalent to the Warco 250vf...I’m interested in getting hold of a manual...

This is a good question....if you haven’t got good elecrical knowledge....where do you go to get them faulted and fixed?
