|Thread: Cheap ER collet advice please|
I see CTC actually give a tolerance run out of .008mm, if they don't meet that standard you can get your money back [Paypal - item not as described, credit card - chargeback] so a win win situation. They would also have to pay postage if they wanted the collet[s] back.
|Thread: Would you buy one of these collets?|
Using a big cutter [i.e. 25 mm / 1"] or above in an R8 spindled machine seems attractive but in practice you would get little or no benefit out of doing so.
|Thread: Warco WM18 milling head shake ( technically spindle is precessing) when plunge milling a blind slot.|
Bridgeport’s certainly had their place in industry, although light by many standards they are extremely versatile & a handy tool, many hundreds of thousands were made so they must have got something right.
I personally found that the bigger Cincinnati’s were good for removing loads of metal when required but didn’t have the ‘feel’ for Toolmaking tasks.
|Thread: What are members thoughts on Gap Bed lathes ?|
I'm not comparing either to each other, just pointing out a couple of observations from personal experience.
My Super 7 replacement is a Warco WM 290V, the Myford wins hands down on build quality & ‘feel’ but the Warco is in a different league for performance.
The Warco is certainly rough around the edges but hopefully decent where it matters & also the ‘accuracy’ certificate is a total work of fiction but worryingly I am getting to like it.

|Thread: UK stepper motor supplier|
Thanks to all who replied! Will report back.
The motor is being used to drive the lead screw/feed shaft on a Warco WM290V so not very fast maybe 200-400 rpm, just seems under powered a bit?
Motor is 24HS39-3008D [**LINK**], power supply is JC-240-48 48V 5A, [JC Power] going into a DM556 microstep driver.
Hope that makes sense.
Old school, thanks i'm not going but will give them a look.
SOD. Bit of a confession, I'm working on the Clough42 [Youtube] electronic lead screw, my son has done all the electrical/programming side of things & I have done the mechanical bits, everything works apart from the under powered motor.
He is in Portugal for a week so I was trying to help out, I will get the information you have asked for but it may take some time, thanks for your assistance!
Can someone personally recommend a decent UK supplier of stepper motors who sell good products at a reasonable price & could offer technical help if needed.
I want this to complete a project whose only problem is that the Chinese supplied stepper motor which is rated at 4Nm is only giving about 2/3rds of that, I’m pretty sure wiring etc. is correct.
|Thread: New lathe?|
The Emco is vastly superior to a Myford in my opinion but condition is everything. I owned a Myford Super 7 for 40 plus years but always dreamt of getting a Maximat Super 11 in good condition. You really need to see it in person & check it over when running.
|Thread: Turning between centres on Super 7|
Face drivers would be ok for low torque work but a bit iffy for any sort of cut.
|Thread: M&W rules now better...|
It's a rule guys, yes make it correctly but only a rule in the end.
And we are led to believe our education system is so much better than it was, as GCSE results improve year on year, never really swallowed that one
|Thread: Metric tap and die set|
Much used question & the standard answer is buy 'quality' [Dormer, Guhring, Titex etc. etc] threading tools as & when you need them. Try Arc Eurotrade, Cutwel, Cromwell tools, RS to start with.
|Thread: M8x1 left hand tap.|
Pretty sure the retailer has to pay postage on faulty items as per UK consumer goods act[or similar distance selling regulations]
|Thread: Ebay site changes for the worst|
Just pay what you think it's worth.
|Thread: Screw cutting is over complicated|
Joe is of course right in what he says.
|Thread: General Question|
SOD makes a number of fair points but if you don't receive your item just claim the money back from PayPal or your credit card, there is absolutely no need to 'write it off'
Ask for a refund!!
