Re: Perseverance Chassis queries re 'ride height'

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...

Re: Airfix 48xx with High Level Kits chassis

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.

Re: Airfix 48xx with High Level Kits chassis

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...

Re: Easing wheels tight to gauge

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...

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?

Re: Swanage (again)

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.

Re: Sparkshot MR wagon

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...

Re: Cutting and Filing Tiny Lengths of Rod and Tube

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.

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...

Re: Best wire for collectors

Phosphor bronze works fine with steel wheels and has the advantage of being springy so you can regulate the pressure on whichever part of the wheel the wire bears on. PB is softer than steel so wear first but for steel to be springy it has to be hard and would tend to wear the tyre. Pickups are easi...
