Thread: Jobs we had as kids
08/09/2020 10:34:58

Between leaving school and starting my apprenticeship, I spent the summer grading and packing eggs at a poultry farm. It took 10 years for me to be able to face eating another egg after that...

Thread: Hermes Parcels
06/09/2020 11:03:31

Interesting, last year I purchased a 4lb hedgelaying axe. It was shipped via Hermes. The way the seller packed it left absolutely no doubt as to the contents and it was delivered fine. Our local Hermes agent (who is excellent btw) even commented that it was an axe.

Thread: Is there any tips for sawing aluminium
04/09/2020 16:18:32

I feel your pain, I went through the same with a 3 x  1 1/2 section and purchased a bandsaw for the next time!
Seriously though the coarsest blade you can get and WD40 should help.

Thread: Stainless steel
27/08/2020 17:39:03

After getting completely fed-up with endlessly buying HP ink cartridges at no small cost, I moved to an Epson Ecotank based printer. Still using the original bottles of ink a year later with plenty still available

Thread: Coping with voltage spikes
20/08/2020 15:55:52

At the risk of thread drift, I couldn't resist commenting on "never go out in the dark ". Many years ago not long after moving into our village, we tried to book the local village taxi to take us to a pub in the next village for a meal.. The answer was "I can take you, will you be wanting to come back", "errr, yes" was my reply. "Sorry I don't go out after dark" was the answer...

Thread: Who trains these ideots?
19/08/2020 15:18:03

Sadly all of us of a certain age can recall similar tales.
I did did a technician apprenticeship 40 years ago and I am still benefiting from skills learned on the job, whether at work or in this ME hobby. The college aspect not so. I would say over 95% of what was learned at college has never been used in anger. The only exception being Optical Loss calculations, which I did in 1987. Landed a job in 2000 where they were darned useful.

Sounds like plumber is his job description, not boiler service technician or whatever they are called.
Maybe experienced in wet stuff, but not electrons.
Seriously though, what a terrible experience. I would not pay him as he clearly is not skilled enough to carry out the task. Is he an employee or a one man band?

Thread: Camlock chuck
14/08/2020 15:41:44

There should be three markings on the spindle nose for each fastening " |" at 12 O' Clock and "V" at 3 and 6 O'Clock. The line on the locking clamp should be between the two "V" for locked. Turn anti clockwise to the "|" to release.That's how Colchester did it on the chipmaster, others may vary the markings, but the principle will be the same.

Thread: By Crook or by Fluke
11/08/2020 20:33:38

Still have my trusty Fluke 77 DMM from the mid '80s

Thread: Old School Projects
10/08/2020 10:33:03

This is a 40 year old school project, still in regular use. A great insight for us at the time into sand casting.

Thread: The making of Steel Balls
06/08/2020 14:51:14

Norm, you are thinking of lead shot manufacturing which was traditionally done in a shot tower

Thread: Colchester chipmaster variant
04/08/2020 09:39:17

To be fair on the OP, it could be a victim of the dreaded autocorrect

04/08/2020 07:39:25

Sean, I have some manual copies. No experience of maintenance though. I will message you with contact details

Thread: New Lathe - poor suface finish on my results
31/07/2020 13:44:58

Jeff beat me to the answer!

I'm no metallurgist, but different steels are formulated with different characteristics depending on the application.
Bolts are typically forged with rolled threads and their primary requirement is tensile strength. Easy machining is not a criteria for this use case.

M10 bolts are a swine to machine, particularly 8.8 grade. Even on an ex industrial machine, it is very hard to get a decent finish.

Thread: DRO installation - a salutary lesson
30/07/2020 09:20:28

There have been other posts on this subject recently that have highlighted potential earthing issues with the machines, that has resulted in earthing currents flowing through the DRO cables. This is a potential safety issue that needs to be addressed ASAP.
1) Check all exposed metalwork on the mill has continuity to mains earth. I would disconnect the DRO scales from the console for the duration of the test ready to eliminate this path
2) Your DRO console should have an earthing point, make sure that that this is connected to the mill metalwork at one point.



Thread: Droop & Rein Information ?
28/07/2020 20:14:37

40 years ago, this September I started at the Apprentice Training School at BAe Weybridge. £30 a week.

Thread: Death of a PSU
28/07/2020 11:13:19

Switched Mode Power Supplies are a technology that in theory are very simple, but in practice very tricky to get right. By right I mean stable and reliable. Much improved over the years as many devices have been by introduction of integrated control ICs. When I was a lad, most were controlled by discrete components and would go bang very frequently and often for no apparent reason. I used to work on early CAD terminals, which had a PSU where its main switching device device would fail short cicuit often. We had a big stock of replacements. TIPL755A, I can still remember the number after 35 years....

Thread: Quality small metric spanners
27/07/2020 20:34:53

The Pro range from RS Components are good at a sensible price

Thread: Death of a PSU
26/07/2020 22:18:24

I'm with Robert on this one SMPSU's aren't easy to troubleshoot and repair.
