Since 1900 odd? That's something to be proud of !

... as long as you don't need to machine them too much. I tried these for a model-engine flywheel once - the skin went all the way through. Quality they are not (nor need to be in their intended use).

Haven't really looked closely at this, but I'd:

- turn the hole in the guard to a close (but not interference) fit on the tailstock barrel.

- locate-drill-tap one mounting hole and install its screw.

- drill-tap remaining holes.

- then open up the hole in the guard if required.

(I hate messing around with shims).

No, it's a website thing. Catalogues don't have pop-ups, roll-overs, dropdowns and zero dead space for the mouse pointer so that the website owners can force in front of your eyeballs things that you never wanted to look at in the first place.

.... but how does that relate to reamer specifications (H7, H8 etc) ?

I don't doubt you're right. Seems a pity that they can't simply give a reliable OD for external holding with the "normal" jaws though and add a disclaimer that it depends on etc etc. Which would at least give potential buyers the basic information they need.

Apart from the (slight) drift of topic, I thought the OP had a point. It's curious that (in my experience as well as his) the largest dia the chuck will accept in the jaws is rarely stated.

Come to that, neither was the material. if it's brass and using a pilot drill first with regular drills, I wouldn't be too surprised at this behaviour.

My belief is that MS, having got enough people on to the Win-10 bandwagon and cut off support for those sticking with earlier versions, will switch to a non-optional subscription model.

Nor do I believe will it be the simple "we'll send you a bill once a year". It will be monthly and MS will demand access to your bank-account or will direct-bill your credit card. Take it or leave it. To me this epitomises stuff that I hate about today's world.

Ain't going there. At my age I don't have to. But as I've said before, everyone around here is big enough and ugly enough to make their own decisions

That said, I tried Win10 when it first came out for a few weeks. Didn't like it went back to Win8.1 on my main machine.
[ this is easy to do as I have front-panel-swapable drives on several of my machines and can prepare 2 drives with the same image and update only one. FWIW I'm about to do it again with the latest Win10 to see if I feel any better about the OS itself. I can't see me switching permanently anyway for the reasons above. ]

It came up on a blue screen (not of death.... of life perhaps?). when I rebooted the Win-7 machine after some updates. It warned of the impending demise of regular Win-7 security updates but a small note mentioned that ongoing support in that area could be purchased. it may have included a link but I can't be sure.

(Just tried rebooting that machine to see if the BS (blue screen) would come up again, but no luck. I must have checked the "don't show this again" box. Sorry.)

Edit: After a bit more digging, this might be what you are looking for.

FWIW, according to Microsoft, security updates for Win-7 are only ended through Windows-update. They will still be providing Win-7 security updates via a paid subscription. (I won't bother).

edit: Interesting thing though: today (15 Jan) I got Windows Update for improvements to the servicing stack. This is the Windows component that installs updates  ( ! )

People have done this with a cable/pulley counterbalance system. With the counterbalance weight suspended behind the machine.

Or a gas strut helps.

That's pretty much unanswerable, Chris, unless you give the approximate size and pitch of the thread you have in mind.

Previously we were discussing ballscrews in relation to the X and Y axes. Here you had moved on to the Z-axis. If the ballscrews back-drive on the Z-axis, the head will sink down the column any time the head isn't locked (or held on the raise/lower handle)

Mostly, people mill with the head locked so it might be possible to work this way. Whether it's worth it though .....

Tubal Cain's "Drills Taps & Dies". No 12 in the Workshop Practice series.

Everything you need to know about threading and drilling. Read it from cover to cover. Make photocopies of the charts, laminate them and put them in the workshop.

We-e-ell ... see previous comments about back-driving with ballscrews.

Absolutely. Some people deal with this kind of tragedy by weeping, wailing and hand-wringing alone. Others lighten the load with a little humour. Either way may be valid depending on the person concerned. Neither way is "wrong".

Which gives us (and Georgineer) the origin of "u-dirty rat"

... or, indeed, vice-versa

(Sorry - time to kill before setting off for Dentist).
