An accurate but pointless argument as there will always be unscrupulous sellers taking advantage of the culpably unwise people seeking unreasonably cheap products by sourcing cheaply and supporting inadequately, the fact that the customer has recourse in law will not change the fact that their money spends significant time invested in scrap as a direct result of them being cheap in the first place.
Why do so many people act all surprised when, having scraped the bottom of the barrel and found one of the cheapest box-shipping options to buy, they get cheaply assembled products and less than stellar service?

I looked at Multi-Fix and found that almost none of the angles I wanted to set tools at were catered for by the 9 degree increments.

That kind of Metrology is available to rent.

Were "Keepers" as provided by magnet manufacturers in the past to "Keep" the field localised or to "Keep" the magnet's strength? :D

YG Alu Power are good in plastics.

How complex is the turning you want to achieve?
I've done some turning in the mill with turning tools held in a milling vice.

Cut away from the shoulder and outwards from the bottom of a bore and these issues are non-issues.
From personal experience, and not from watching YouTube videos, it's easier not to open the half nuts when cutting Metric threads on an Imperial lathe

Complete and utter bunk, if you have no previous and are of good character you need have no fear in carrying anything which isn't illegal in itself, no one will be interested.

Is anyone using a 3D scanner to capture parts for 3D printing projects?

I've tried various linked belts and all of them require greater tension than a conventional belt to transmit the same power on my Super 7, fine for industrial machinery but possibly not optimal for the long term health of the plain bearings on a Myford.
I do regularly make use of the full 1hp available to me though so anyone performing only light work may never have any issues.

Better still is a VFD to increase the rpm as the cut radius decreases, with a little ingenuity an easily built linkage can be produced to actuate a speed varying potentiometer.

Anyone who hasn't owned and used a Long Bed might think it's just a longer version of the same thing but they'd be dead wrong, the Long Bed is a much deeper and far more rigid casting, I don't have any of the rigidity issues which are generally talked about in conjunction with Myford 7 series lathes, parting 30mm stainless is a breeze.

The only reason you might not know this already is if you were not interested enough to read around the subject in the first place, this is not news, I was reading warnings about ventilation 4 years ago when I first researched 3D printing.

+1 for Zapp Automation, excellent supplier.

Make a steel guide bush and clamp it in place to guide a 4 flute carbide endmill, your pillar drill will easily accomplish this.
A brass guide bush would probably be fine for a one-off.
Note that I am speaking from commercial experience here, not speculation or theory.

Browill Rewinds are in Sheffield and supply excellent industrial quality motors.

Your choice of friction modifier can make a difference.

You can sharpen one drill flute manually with a stone to give the tip slightly asymmetric geometry, this will then drill a slightly larger hole than a symmetrical grind.

What torque are you tightening to?
I never had an ER collet slip after I looked up the correct tightening torques.

I machine tap Nylon with spiral flute taps, the threads have enough resistance not to shake loose but are not difficult to tighten.
