Thread: Lest we forget
06/06/2021 13:23:56
Posted by J Hancock on 06/06/2021 13:20:38:

The question I would like to ask, to all of those who sacrificed their lives for our 'today' , is this.

For what we are today , would you do it again ?

Absolutely pointless, they were 'of their time' as we are 'of our time'. there was a job to be done and that was the end of it.


Thread: Scalped on my doorstep - it left an unpleasant taste in my mouth.

Never a good idea to buy from cold callers for anything.


Thread: Master key - precision chuck.
05/06/2021 19:28:05

A 3 jaw is a 3 jaw, never super accurate but good enough. Not the best work holding device for 2nd op machining.


Thread: Sine bar
05/06/2021 12:42:53

As long as you know the roller centre distance of the sine bar it's simple trig to work out an angle.


Thread: Ebay Chancers
05/06/2021 08:49:15

The Ebay vice is wrongly described, it should read 'boat anchor'


Thread: Lathe run out

If you bturn a waist on your bar so you have 2 'collars' at either end you only need to turn those for your test. instead of traversing down the entire length.

He's been told this alreadysad

The bar will be bent upwards...

The OP says, "turning parallel between centres ".

You link to equations for a cantilever beam, which implies encastre at one end. How does a pointy centre do this?

Oh god here we go! crying

Thread: What are these morse taper collets for?
01/06/2021 13:33:19

From distant memory they are adaptors for holding parallel shank drills which then go into capstan lathe turrets.


Thread: Screwcutting on the Bantam
27/05/2021 20:49:37

What idiot ‘designer’ would use 27 TPI? 🤬


Thread: Stupid moment
26/05/2021 18:24:58

Most of us have there. 🥴


Thread: Mitutoyo Digital Callipers

Loads of posts on the net about fakes, suggest you don’t support criminals but save up to buy genuine items.


Thread: Distilled water for anodising
21/05/2021 08:59:50

Yes dehumidifier water will be same as distilled but as Andy G says can be dirty.


Thread: Wire EDM - an amazing capability for the home shop
21/05/2021 08:58:35

I worked on 2 Fanuc wire eroders cost £100k each for many years, absolutely brilliant for 'home projects'.smiley


Thread: Water soluble coolant
20/05/2021 10:38:06

Never had a problem with the table etc rusting using the correct strength coolant but yes I have seen rust under vices. I used to apply oil liberally under the vice bottom before bolting down.


Thread: Help needed on Boring Bar insert.
19/05/2021 16:30:19

Not for a threading insert.


Thread: Laser Cutting Guide for Femi NG120ABS bandsaw
19/05/2021 12:47:39

I was interested in one of these until I saw the pricefrown I will have to stick to my old Kennedy Hexacut.


Thread: Tribological query re shafts and bushings!
17/05/2021 13:09:23

No not ally or Mazak as it's magnetic to a degree. End structure looks porous so I'm thinking sintered with some sort of ferrous material but has a polished looking surface on all external features either from the sintering mould or a sizing die.

Definitely not machined, on careful examination I think possibly extruded.


Or sintered & 'sized' using dies.
