|Thread: Newbie with a chuck query|
Colin is a relative beginner. Talking of regrinding requires at the very least a grinding spindle or Dremel with a suitable tool post mounting and making/buying the gadget for holding the jaws open at their tip and you'll still be left with a chuck that won't hold anything smaller than 1/8th", assuming his efforts are even successful. Seriously, just buy another chuck because you will eventually anyway when the shortcomings of the first rapidly get annoying. Since the one supplied has obviously been swept up off the floor from under a bench somewhere, the scroll and inner workings could be well knackered. Even PB say it's often more expensive to repair than replace. I'm reminded of a friend of mine who used to work as a car mechanic and the customers that used to think a £25 service would make their 200,000 mile car like new.
Did it come with both sets of jaws? If no then it will be cheaper to source a new (second hand) chuck. It's such a basic but necessary and central part of lathe turning, it's worth starting off with a "good" chuck rather than trying to compensate for a bodged one.
|Thread: Milling curves|
Amazing skill on show in that video. I like videos like that. They actively make you want to break out the files and have a go.
|Thread: R8 instead of MT3|
R8 is my personal preference. Bridgeports use R8.
|Thread: ML7-R tumbler gears|
There's a couple of decent second hand ones on eBay as we speak. I think I have a pair of good ones somewhere.
|Thread: ER25 or MT2 Collets|
A set of ER collets will hold any size, imperial or metric. MT2 will only hold their designated size.
|Thread: Windows Update (Again)|
Without igniting the old debate (again), all I know is I was a loyal user of Windows and PC's since 1995 and they were regular sources of stress and frustration needing constant updates that frequently screwed existing programmes up along with painfully slow boot up times. I bit the bullet four years ago and bought a Mac Book Pro. What a difference! None of the grief I previously had to put up with. Never going back to Windows.

|Thread: VMC Mill alignment|
Your description, assuming you're measuring technique is reliable, suggests that the top of the table is square with the body of the machine and the head is where the error is. It can either be at the join where the head swings left and right (yaw), or the join that allows the head to roll not being square, or all the above is fine and the quill itself is not bored squarely with the rest of the machine. I had a similar problem but since I don't use the roll or yaw, I put a thin piece of shim brass (maybe only one and a half thou) in the lower part of the join that allows the head to roll. The shim is quite wide so I get a solid triangulated joint when bolted up. It's been like this for at least five years without issue and beautifully square machining.

|Thread: Will we be able to see Asteroid 2019 EA2 when it passes earth on March 22nd.|
Nearest approach in the UK will be 3 in the morning. It'll pass at roughly 200,000 miles which is not much nearer than the moon. It's approximately house size so if you have a telescope that could resolve a house on the Moon while tracking the object, you stand a chance. Otherwise, it's unlikely you'll see even a pin prick of light without knowing where to look.
|Thread: Soba rotary table|
That's the one I've got and your experience pretty much matches mine except in my case there was no hardened grease problem. It's a nice piece of kit well worth the money.
|Thread: Dore Westbury Mill|
I've seen the machine (that's how I know about it) and it's a fine example. I think it has the very useful Dore Westbury design vice to go with it that opens much wider than a lot of commercial vices. I used to own an identical machine many years ago and they're very capable.
|Thread: Errors and Omissions|
Drawings can be altered providing the author or their estate are happy for it to happen and that the person "publishing" the drawings also has the right to publish them.

|Thread: Dore Westbury Mill|
Home And Workshop Machinery have just taken in a Dore Westbury. Worth talking to them. Although they're in SE London, they will deliver.
|Thread: Machine tool suppliers|
+1 for Chris and Steve at HWM.
|Thread: Soba rotary table|
Myford milling machines were made in Taiwan but tweaked (if necessary) by Myford (i.e. quality control checked) BEFORE they went to the customer. I've had VMC for years and very pleased with it. Michael hits nail on head (see my previous comment).
I've mentioned earlier on in the thread that the two (older) Vertex rotary tables (and a couple of collet sets) I have I'm very pleased with although ironically all the chat here about changing allegiances to different factories and missing bearings while creditably honest actually weakens my faith in them as a brand. It comes back to my previous point about how is a customer supposed to grow faith in a particular brand and choose them over others if the brand keeps changing their standards?
It's not about chasing tenths of thou's. It's about the failure to meet the basics claimed for the product. One would expect a collet chuck designed to fit a Myford spindle would actually be able to be screwed on and not be too small. It's not unreasonable for the customer to expect the product to actually do that simple thing.
That is what annoys me the most too. I simply don't want to buy something based on pot luck and the continual aggravation of sending stuff back and forth until you get a good one.
Glad I'm not the only one although stating it can get you vilified.
