|Thread: Cheap chucks from ebay.|
I've bought India made chucks, very good value and nothing wrong with the couple I have.
|Thread: Einstein theory of relativity|
As one ages any given time period becomes less and less of a percentage of your entire existence and therefore seems shorter.

|Thread: Uploading documents other than jpg's|
OS or program dependant files (such as Word or Excel documents) are not universally correctly readable.
|Thread: What web browser|
My IP address is not "fixed" as such but it rarely changes, certainly logging off and on again would not change it.

Supposedly TOR is the most secure of all browsers
|Thread: Barn engine on eBay|
|Thread: Brake discs a suitable source of case iron|
... but not a cheap source of cast-iron as genuine anglepoise lamps sell for fifty quid upwards.
Vauxhall Nova solid brake discs - eBay item 301833633434 - £7.34 (inc post)
|Thread: oakey resin fibre discs|
"fibre washers" entered in an eBay search brings up quite a lot.
|Thread: Parting off alluminium|
I cut at a slow speed as far as I can until I notice the first signs of sticking then back right out and take another cut to one side slightly less than the tool's cutting width thus having a wider cut. Return tool to original position and continue cutting which it will now do without sticking. Usually once is enough on say a 2" diameter piece but might need to do same again on a much larger diameter. Takes longer to explain than do it
(Edit: Having typed that I now see Eric does the same! )
|Thread: "Tang" on the end of a male Morse taper?|
I've often found this necessary but wondered if what I was doing was correct. Glad to now know it is the right method.
|Thread: What is this for please?|
If it's model engineering sort of size you could try asking on the Mamod forum.

|Thread: Scrapping an Electric Cooker|
Some lovely cast iron plates on ours but no chance to get them. The cooker is 35+ years old and still as good as new. It's extremely well made and I'm pretty sure it will outlive me.
|Thread: Small-Medium Lathe|
I have a 9x20with different maker's label but it's a generic Chinese lathe that come in many variants but are all much the same. I had a few minor improvements and adjustments to make when I first got it but nothing much. Very pleased with it.
|Thread: Euro space station|
Don't know too much about the subject myself but there's a chap, John Fletcher, about half-a-mile from me that has his own observatory. Mount Tuffley Observatory
|Thread: Newb question|
The only 18 tpi whitworth I can see on the chart is 5/16"
|Thread: eBay P&P (Barrack Room Lawyer)|
Sellers cannot leave negative or neutral feedback. For several years they can only leave positive or none at all.
|Thread: Lathe Accuracy|
I've seen extraordinarily good work turned out from old far from accurate lathes. I've also seen very good lathes that have never done any serious work at all, aside from turning out test bars.
|Thread: Lathe backplate chuck help|
You've had rather a bad start to your lathe but that 39x4 spindle thread is really the only troublesome feature to overcome. Everything else you might need is easy to come by and fairly standard. The 9x20s from many sources are all the same machine under different paint jobs.Grizzly, Jet, Enco, Harbor Freight and many others - they are all basically the same lathe.

This is the Grizzly manual but it is identical to your lathe,
