Given your location, Paul ... it might be worth having a chat with Bede Tools : **LINK**

I have never dealt with them, but do look at the site occasionally.

I don't think it is easy to measure the mating gear as most trains have the axle mounted gear at 90 degrees but then again don't they use a worm on the motor to drive a mating wheel?

.

That does appear to be true of ‘most trains’ Jason ... but Eric was quite specific :

“ ... which will end up being an armature pinion on a Hornby O gauge Locomotive.”

I know very little about Hornby O gauge Locomotives ... but must assume that at least one model used spur gears [unless Eric is building a special]

The problem is that with a small number of teeth such as your 0.5MOD gear is that the teeth need an undercut […]

.

A quick check on ‘Easy Gear’ suggests that no perceptible undercut is needed for 10 teeth at 0.5MOD

I've just looked at the Lidl website, the welder is going to be on sale from Sunday. The pictures of the welder now show an entirely different machine. […]

That makes much more sense ... and this might help: **LINK**

Frustrating as it is, Derek ... that should be just a simple rewire job.

Let’s hope the previous owner was a better mechanic than electrician !

... Fortunately it does look that way.

Screwfix sell this which looks like Mapp gas, complete withy the double 'p', but whether it is the same as the old version of Mapp gas I have no idea. May be worth investigating.

Thread: Silver Soldering Brass
16/01/2020 16:56:19
Posted by CuP Alloys 1 on 16/01/2020 16:26:56:

Hi Chris,

Do not use borax flux with silver solder. It does not start to work until you have overheated the joint and alloy.

[...]

But put that borax in the bin unless your filler metal is brass.

Keith

Keith,

I hope you will forgive me the impudence of adding a footnote [*] to your excellent advice.

... especially as I am straying from the specifics of this thread.

[*] Although unsuitable for the materials under discussion; Borax is widely and successfully used when Silver-Soldering Silver.

Michael has a magic touch finding interesting internet references! [...]

There's no 'magic touch' involved, Dave

As I wrote earlier "[it's usually just a matter of knowing/remembering where to look]"

I remembered copper.org from previous visits, and just put 'lead solder' into their search box

A few seconds skimming that document confirmed that it contained the words and pictures I was looking-for.

Thread: Driving Small Taps
16/01/2020 09:20:04

If, for whatever reason, it is impractical to use any system of alignment ...

When working ‘freehand’ with a small tap, I clamp the plain shank of the tap in the pin-vice, instead of using the square: This provides some ‘safety’ by slipping before the tap breaks.

Interesting to see that cdkeys appears to have changed tack since this review: **LINK**

https://thelegality.com/reviews/is-cdkeys-legit/

[/quote]

As their name would suggest. game cd keys are the main source of business for cdkeys.com. However, they also trade in various gift cards and top-ups. Many of cdkey.com’s competing websites like Kinguin and G2A also sell various software keys, such as Windows keys and Antivirus keys. However, cdkeys is still almost entirely focused on their specific niche – video game cd keys. They don’t sell in-game currencies, virtual skins, Windows keys, or anything of the sort. Cdkeys has its niche, and it’s sticking to it.

It’s of no relevance to me ... but thanks for your clarification

I am still weighing up the pros and cons. My usage will be in clock repairs. For example if for any reason I needed to repair (solder) a tooth into a large brass wheel I would I feel be constrained to using soft solder […]

... That would be the safer option anyway; particularly on 18th Century Brass
