Thread: Just splashed out on a precision instrument
24/11/2017 21:05:27

Unless my eyes deceive me the OP has written Miluloyo and that is exactly what it says on the dial face, therefore it is NOT a Mitutoyo dial indicator but one of those items of fake Chinese junk that are catching out the unwary, with increasing frequency.

Thread: Runout turning between centres
23/11/2017 15:45:18

I like Hevanscc. . He knows what a live centre and a running centre are AND he knows where they go. That is so rare these days. What a heartwarming posting to read.

Thread: BA threads. Why the tpi?
22/10/2017 14:04:06
Mmmmmmm, BA. Strong threads in small sizes. I remember learning about the genius of this geometry probably 50 or so years ago. None of yer stupid weak knee'd metric ISO malarky and all that sails with it. Viva le BA.

Don't worry about them being too hard to turn. They're not.
Thread: Help with Myford Saw Table?
11/09/2017 14:58:07
It's not for a sliding fence. It's for a protractor attachment for angle cutting.

The magnetic pull could also lift the saddle and bend the tool above centre height., , in my opinion,
Thread: Level lathe set up
17/08/2017 10:00:22
Hoppers post is really heartwarming. I now know two people (including myself) who realise that there is absolutely no need whatsoever for a lathe to be level. The only requirement is that tha ways are flat and true in and on one plane rather than twisted or under torsion. If you doubt the veracity of this just take a look at a CNC machine with the bedways at 45 degrees to the vertical. There ain't no way that position can be called level.
Thread: Arduino &c for dinosaurs

Dear bewildered Rob, , don't feel bad about not having a grasp of this. Quite simply, I don't even understand what your original post is saying or asking. Seriously. No joke. I'm clueless. I know what most of the words mean,but in this context I'm blind. However, if this is connected with CNC then I'm hoping to learn and widen my knowledge. Presently to me CNC is as alien as a mobile phone would be to a medieval wheelwright. Onward and upward.

No, speaking from experience they are in fact a bang up to date feature.

Thread: Screwcutting on a Myford ML7
14/07/2017 16:26:47
They are nothing more than idlers. You can have ten in a row and it makes no difference whatever to the in / out ratio. Basic mechanical principle.

It's not a ring main. It's a ring final circuit.

It is probably low grade cheap and nasty mild steel. When they recycle cars now they shred the whole car and this goes off to be made into new non structural steel and it contains boron,nickel, chrome and all sorts of exotic material!

Some of the steel I get cannot be drilled after it has been forged and can even shatter. Unless you buy structural grade mild steel now, you can end up with any old crap in it!

Ordinary hospital beds are made from mild steel then plastic coated. They are made to a price not a quality.

Edited By vintagengineer on 30/06/2017 21:31:10 You possibly haven't read the bit on the first line at the top of the page stating "Fully adjustable Bariatric bed". In addition you possibly missed the post stating "This is a modern bed costing thousands". I refer you to the post by Ian Skelden2. It contains a factual account. I shall add that I have experienced these problems whilst doing trial mods to these beds several years ago. Keep the term "Bariatric" in mind when considering the bed construction.

Thread: Avoiding Work Holding Damage: How do you decide the cutting order?
01/07/2017 07:51:50
If you want a fairly straight answer here's two.
1, Sparey. The Amateurs Lathe.
2, Tubal Cain. Work holding in the Lathe. All being well you should never need a third answer

Thread: ML7 cross and top slide threads?
19/06/2017 19:09:34
Thank you Michael G. I do come in handy sometimes. Thankfully.
19/06/2017 16:18:38
I will add this to assist the thought process. ML7 top and cross feed screws ride with the slide. A left hand thread needs to be used where the slide feed nut rides with the slide. ML7 's have a nut captive on the carriage and the topslide base. Therefore, a Right hand thread needs to be used.
19/06/2017 16:10:04
ML7 top and cross slide feed screws are RIGHT HAND ! The nut is stationary and the RIGHT HAND feed screw pulls toward the nut moving the slide forward. If it was Left hand it would back the slide off when rotated clockwise. I've machined new screws and nuts for six ML7 lathes in recent years. The LEADSCREW is Left hand, were it not clockwise rotation would drive the carriage toward the tailstock, not the headstock. Have a think about it.

I hope to God they're NOT left hand. Otherwise they would work in reverse !!!! And there's no 'possible' about it. They are Acme form.

Thread: Model Engineers Workshop Lost The Plot
12/06/2017 16:46:57
Just home from work to find my latest edition through the mailbox. I've got a complaint. I cant find my pull out copy of the 8 foot by 6 foot full colour poster of Super Neil racing the jet. Honestly, I'm sure MEW is losing the plot.
