Thread: Fly press weights.
22/01/2020 01:37:53
Posted by Paul Lousick on 21/01/2020 09:55:19:

Dumbbell exercise weights are a source of cast iron discs.

... 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).

Thread: Hemingway Myford Tailstock Swarf Guard
21/01/2020 01:09:35

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).

It might be an age thing, but I can navigate my way through a catalogue to find what I'm looking for far faster than a web site.



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.

Thread: Reamer specifications ?

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

First; there are two sets of jaws available

Second; the other features of the workpiece [length,weight, surface finish, etc] all need to be considered

Third; need to take into consideration the type of machining to be done.

In these litigious times, Suppliers may feel more comfortable simply avoiding the issue and letting the user make his/her own considered decision.



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.

........but the thickness of the plate was not specified.

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.

Thread: Windows 7 support ends
16/01/2020 18:29:39

But as a happy W10 user I have no idea why so many folks fear changing.

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. ]

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.

Do you have a link for that?

 

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.

PC World recommends not using IE if still on Windows 7 as not security supported on that 7 system.

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  ( ! )      dont know

Thread: Warco WM18 lead screws upgrade
12/01/2020 19:04:21
Posted by petro1head on 12/01/2020 18:58:06:

i am looking at the z axis not from a back lash point of view rather for smoothness and less friction

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

Or a gas strut helps.

Thread: Does a particular thread hold better into brass
12/01/2020 18:57:20
Posted by Chris TickTock on 12/01/2020 18:04:01:

Does a coarse thread hold in a 1/8 thick brass plate better than a fine one?

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

i have re thought thing and am still thinking about a ball lead screw for the Z axis. The would mainly to make the up/down of the head easier

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

Ah, had missed that

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.

Well I'm sorry if I've offended anyone.

I certainly don't want to make light of human or animal suffering, but I thought a touch of humour about what's really a good news story amidst all the gloom might lighten things up a bit.

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".

I disagree, always paper away from wall. It is easier to grasp it that way.

I once heard the only logical reason I've noticed(as opposed to blind preference) for doing it one way or the other (in this case towards wall):

.... imagine that you have small kids.
