Dear me, what a faff over music. Since this is a virtual show we all have control over volume or can mute according to taste. Much better than a live show that I exhibited at that had one layout playing the Corrie Street theme every 20 minutes or so for two whole days! I for one want to thank Danny ...

A fret of chopper couplings can be obtained from Branchlines nowadays. Either five or five pairs per pack.

Thanks Ivan. They look the part, I just wonder how practical they would be for operating.

Well, I’m impressed. That certainly qualifies as “small” Ted and with all the bits fitting inside to boot. Thank you.

Cheers,

David

PS Those “chopper” style couplings look the part for narrow gauge. Whose are they?

What Ivan and Philip said. And which shade of paint did you use to match the original?

Cheers,

David

I’m not sure if LePage is available in the UK but their product “No More Nails” does the job. Barring that adhesive caulk should do the job, just make sure you get something for indoor use as the outdoor stuff has an awful pong.

HTH

Looks interesting Ted. When can we expect to see “Christine” running under battery power? No, seriously, is it possible?

I can think of two advantages for a rear mounted tool post, specifically one dedicated to parting tool use. First: the tool would only have to be adjusted once for cutting height until such time as it needed sharpening thus saving the faff that occurs even with rotating tool posts of getting everyth...

Hi Peter, Not a Perseverance chassis but an SEF one for the Hattons SECR P class but I suspect the experience would be similar. I reduced the depth of the sides first by tack soldering them together and then rubbing down on a 2nd cut file while frequently offering up the side to the footplate to see...

That's interesting. But doing that on a 0.5mm drill? Not so sure. Worth a go though, thanks for posting that David, I had no idea there was a cure for the grabbing effect. Mike Prompted by your comments I had a quick search and it is possible to get drills for brass that are designed for the purpos...

Paul, Brass can be a pain as drill bits tend to grab. The problems you are encountering along with similar problems encountered by others on the forum caused a memory (or something) in my mind to click that there was a better way of drilling brass and there is; https://www.model-engineer.co.uk/forum...

Now that I've seen what a difference a representation of inside valve gear makes, I'll be looking to see what information I can find for a suitable representation. I have some detailed photos sent to me from the locomotive at Bressingham, but annoyingly not one that gives the overall view, to show ...

There is another way to shift wheels without resorting to brute force. I posted an article to Scalefour News 145 (December 2005) P9 describing how to make a wheel puller from a cheap G cramp (clamp). It works in the same fashion as the as the GW one but instead of pulling at the rim it applies the f...

... your work ethic is inspirational :thumb :thumb Shouldn't that be 'play' ethic :D for myself the moment it becomes work is the moment the hours appear to stall :thumb ... never really had much work ethic but miraculously still manage to churn out what is often called work :shock: Interesting. I’...

About the lost wax castings and drilling, has anyone tried annealing them first or is the alloy of brass used for casting just going to be hard no matter what?

Cheers,

David

PS, Brilliant stuff Lindsay, your work ethic is inspirational

Another way forward for return cranks can be found here: https://www.scalefour.org/members/newsarchive/dl.php?f=S4-149.pdf. Dave Booth converted a Bachmann WD and outlined the procedure in S4 news issue 149 (2006) on page 11. The only catch is that it requires a lathe or access to one along with som...

A Canadian invention as it happens, https://www.robertsonscrew.com/. Far superior to Phillips heads IMHO as they don't strip as quickly and the screw can easily be carried to the job on the screwdriver tip.

Neil, I think as a rule of thumb the number of brake bits increases with the date so the early version would have minimal braking and later, say about 1937, would have levers both sides at the very least if not brakes and levers. Your model has bottom doors IIRC so brakes and levers both sides would...

There are tube cutting jigs/vices such as the one below from the Tools 'n' Tools site . They are not cheap (this one is £25) but if one is likely to be cutting tube (or rod) of a certain length, repeatedly, then it could be a useful investment. David, have you found a minimum length you can cut? Pr...

Hi Neil, Mr Hornby was not thinking about P4 modellers when he designed this van. I took one look and decided a Parkside kit was a better idea. The closest I've come to it was doing the Hornby LMS Horse Box which was a bit of a faff and I'm not happy with the results either. It's in my sin bin waiti...

Fair point Tim. The idea is based on the theory put forward by many who argue that in some engines there is little to no room for the motor to rotate so they don't even bother with a link. Being a belt, braces and a bit of string type I thought this idea a bit tidier plus it let me run the engine wi...

Since the conversation is about torque reaction links, I have one that seems to work but I would appreciate constructive criticism of it. It is mounted on a modified SEF chassis for an SECR "P" class 0-6-0T and consists of a simple horseshoe shaped length of N/S wire that hooks on a frame ...

I agree that there is a resemblance to the Fairlie but there is also a strong resemblance to the work of one Mathias Forney as can be seen in the picture at the head of this Wikipedia article https://en.wikipedia.org/wiki/Forney_locomotive

David

Unless my eyes deceive me it looks like you are going to make those catch points functional rather than cosmetic. I am impressed.

Cheers,

David

An interesting looking clamp David. I could have used something like it recently as I’ve been making bearings from brass tube for pulley wheels on a Langley model of a Ruston face shovel. The white metal castings are a bit soft and the holes not always true due to registration problems so bearings a...

Looking good Neil , only 4,358 chairs to go

Be safe, stay healthy.
