|Thread: What are these electronic components called?|
Zero Ohm Links
Sure you've counted them right ?
A 'standard' stranding for some US stuff is 33 wires / 32 AWG ( 0.008" dia. ).
This is 0.75mm^2 cable.
Other options are available ..
|Thread: B C wooden lampholder adaptor|
|Thread: A memory test for the Electronics Wizards|
PIR sensor IC ?
One similar to this ??

|Thread: Would anyone know where I can source On Off Decals?|
Some toggle switches come with them.
I don't suggest this switch is suitable for your application, just an eg.
No idea where you can get them for rotary-type items if that's what you have.
Pic. of YOUR switch would help.
When I was at work ages ago some had an engraved plastic thing ( sort of black/white sandwich, can't remember the name of the stuff, gravelux ?? )

|Thread: Plums or Gages (i.e. Greengages)?|
You sure it's mould?
We had a damson and the fruits always had a whitish-grey 'bloom' which is, AFAIK, normal.
If it is mould it's probably botrytis and a search should produce images of that.

|Thread: Brass terminations for wire?|
No idea if it's what you want though.
Ross-Courtney Eye terminations.
But Ross Courtney is / was a company who make / made many types. ( So it's a bit like 'Tufnol' covers a lot of different items )
Not seen or used them for ages, used to be common on hot things like the wires from iron elements, thermocouples etc.
It appears they have gone tits up ...

|Thread: Screw Suppliers|
When I was at work we used these folk.
NOT brass though. All S.S. I think.
They also had odd stuff not listed on site so just ask.
|Thread: Temperature controller explosion.|
They are, to some extent, self-healing.
If the environment is prone to nasty voltage spikes the device needs a MOV. That's what they were designed to deal with.
Incidentally, MOVs degrade over time. We had to change them every year on some sensitive kit.
[b] Suppression of radio frequency noise either incoming or outgoing.
[c] Probably. I've known them to fail for no other reason than they felt like it with no problems after replacement.
Thee may be 2 other caps. ( probably smaller ) from neutral/ground and phase/ground in a 'Delta Suppressor' arrangement. Not always fitted.
PS Andrew has faster fingers it seems ...

|Thread: Doncaster show|
Edited By Dave Daniels on 11/05/2017 17:39:40
Any reason why online tickets are no longer available ? Seems a bit early to stop.
Did intend to go but not now. Just have to get used to being that little bit wealthier.
IIRC Last year the online tickets for Warwick were still on sale until much nearer time??
|Thread: P-Power hacksaw|
I use a wiper motor for a mill table x-axis feed. It's for VW Golf, made by FEBI. Cost about the same as yours.
I think they do run hot. Off load @12.8V the casing on mine tops out at some 53oC according to my IR Thermometer. after some 30 mins. or so.
Does not get so hot in service despite being loaded as it's PWM
(Sorry, can't see any way of doing superscript for 'degree' ).
This one, I think.

|Thread: Turning a finned aluminium cylinder barrel for a motorcycle|
It was done the other way round ... ally cast onto the other bit.
Wellworthy Alfin process IIRC. Velocette etc. ???
|Thread: Doncaster ME Show and Warco.|
I've done Derby - Guildford MES Show in one day, no big deal. Although it was on a Sunday, not Saturday.
Leeds isn't all that further. ?? It's about 1 hour north of me, so that would make a 4 hr.-ish one way.
IIRC my journey ave. was 56 mph. or thereabouts.
IF Warco held the Open day over a weekend then I'd probably consider having a look.
Didn't Warco once have a Northern Showroom at Warrington, or am I hallucinating again .... ???
|Thread: Why don't we make models of things like this?|
I have a fair interest in this sort of thing:
One of the stoppers ( ? ) is the difficulty of getting Silicon Iron laminations or Soft Iron.
Tried some years ago but got nowhere.
One educational supplies site actually listed 3/8" soft iron rods but were actually mild steel when quizzed.
Unless someone knows where the stuff can be obtained in smallish quantities.
|Thread: Polycarbonate sheet|
Doesn't have to penetrate ... I've used it to get adhesive heat shrink off. If you can get an edge it appears to creep in and destroy the bond.
Not a quick job I admit, but it worked.
Relatively cheap to try it. If it doesn't work you still have the can for attacking sticky labels.
You might try something like 'Label Off' spray.
I get it from Rapid Electronics but no doubt similar stuff is available elsewhere.
Fairly benign, I've used to to get the damn sticky labels of plastic stuff many times and it does not seem to affect them.

|Thread: Fireproof Overalls|
Sodium Silicate aka Water Glass has some fireproofing effect.
