Thread: Mill hand wheel upgrade
20/08/2019 08:22:05

Have you asked Arc Euro?
They carry metal hand wheels for lathes, maybe they would fit the mill?

Re. the Folkestone sand pumping.
Every so often a loud clanging and banging was heard in the pipe and eventually a cannon ball would be deposited on the sand heap.
We told the manager it was skulls from a disturbed war grave at sea

"No! don't say that lads!! we're behind as it is.

use the plug but make the piece longer with a tapered lead in that you can cut away later.

Thread: Using a lathe
30/06/2019 08:22:26

The old tech scool I attended started everyone in the machine shop and carpentry shop at 11.

The metalwork master Charlie (Cog) Wheeler demonstrated the cutting eficiency of the bandsaw by bringing in some pigs trotters on the first day.
He said nothing, started the saw, sliced the trotters into little bits which he threw in the bin then said
"...the saw doesn't care. That could be your fingers, any of the machines in this shop WILL do that if you piss about with them".
End of H&S sermon.
There were a few scratches and minor bruises in there over the years, nothing serious, we all got worse in the corridors.

Thread: Chinese tacho - beware

Fluke have 3 factories, 2 in PRC and one in Germany.
The Fluke multimeters are tested and callibrated on an instrument made in Deal, Kent, codename 'Baldrick'.
Each factory has 2 such testers.
The main problem in manufacture is the fake parts in the supply chain.
Even the PRC guys get caught out.

Maybe a vernier on the indexing head?
360/25 = 14.4 deg.
(= 14 deg 24 arc min ).

Thread: Quicksilver
04/06/2019 08:18:07

As an aprentice one of my jobs was to scrape the 'silvering' off the backs of old mirrors and save the scrapings in a bottle.
The mercury gradually fell to the bottom and was decanted off to be sold to 'the mercury man' who attended annually.

Alas, no more.

Thread: What are you using for Lathe Way Oil?

Thread: The Workshop Progress Thread 2019

The new shed/workshop is finally erected, I've been aiming for a better set up since we got here last October.
8' x 10' from ShedsAhead of Port Talbot who did the installation.
Because of the slope and underlying limestone it sits on 18 4"x4" piles.

Next the power and light, then the benches. I've been saving the old kitchen units and worktops for this job.

The usual solution for this, when using astro telescopes, is to incorporate an absolute encoder to see actual movement rather than rely on step counting.
The cheapo diy version uses an old mouse encoder wheel.

Before the big footed structural guys get in there to shore it up, let the glaziers pick over the rubble.
Sort each fragment of glass into seperate boxes marked with the position found.
More importantly what depth or layer it was found in.
The drafts in a fire can suck fragile glass from one end of a church to the other.
We found that out after the York Minster fire

Thread: Dialect expressions
14/04/2019 08:53:21

In the (former) Kent coal field there's a mix of Welsh, Yorkshire, Gerodie and Kent spoken.
In a study by the local uni Aylesham was found to have a distinct dialect of its own.
Alleys are 'jitties'. Lunch taken to work can be 'snap' , 'bait' or 'scran'.

Thread: seals for mini lathe tapered roller bearings?
02/04/2019 09:10:51

I read that the original mini lathe design was of Russian origin and used TRBs. The later Chinese version used ball races.
Maybe an old drawing could be tracked down?

Thread: Chinese 7x10 lathe

+1 for the 16" sc3.

Thread: Glazing Bars
30/03/2019 09:21:31

Bit late spotting this one. I had to make 2 long clock cases in the glass works for the local time ball tower collection.
I used a 5/16 'bird mouth' hardwood moulding on the corners and 2mm picture glass for one.
The moulding could be made up from 3 x quadrants ?

3/8 x 3/8 brass angle, mitred and soldered for the other.

Thread: new workshop

CAV installed new machines which upset the neighbours. We fitted tripple glazing and the walls and ceiling were foamed.
Still the noise travelled to the neighbour's houses.
Various materials were tried as insulating blocks under the machine feet, but eventually balsa wood was judged the best in this case.

Welcome Justin, lots of ATMs on here.

Thread: Hi from Deal

Hi Dave, I recently moved away from Eastry to south Wales.
If you are looking for scrap pieces and off cuts try the scrap man off Poulton Close,( Coombe valley road).
He will let you root through the non ferrous bins and sells by weight.
