Re: Easing wheels tight to gauge

It can be tricky to line up the claws so that the spigot engages with the axle end especially as the claws move independently. It occurs to me, though I've never done it, that filing two slots in the plate edge at 180 degrees to seat the claws might be helpful in orienting the spigot.

Re: Easing wheels tight to gauge

You may well be right though the pull (at the tyre) and the push (at the axle/hub) are equal, surely?
Whatever, this is a useful bit of kit which does the job.Just like Mr Watt's other tools.

Re: Easing wheels tight to gauge

This is what the GW puller was designed for. And it's pretty effective. As a cautionary note it sometimes helps to file an axle sized slot in a brass plate to fit between the back of the wheel and the frames for the puller to engage with. It should be a little wider than the wheels. This spreads the...

Re: Motor Shorting

Invest in a pack of Rizla fag papers and use them to insulate the inside of the splashers where the flanges short. Fix in place using a thin coat of varnish or superglue. You won't find anything that's much thinner.

Re: Motor Shorting

That is a beautiful model of a fine engine.

Dave Bradwell makes a good point about the brake shoes. I now make these from Paxolin ( sleeper strip) to guarantee elecrical isolation on my split chassis models. Scrape away the copper once the shoes are fixed to the hangers.

Re: Motor Shorting

If you can it's best not to have any of the bodywork live because current can pass through the buffers to other vehicles. Insulating the chassis from the superstructures is recommended. Your photos suggest that this could be a bit of a challenge on this loco!

Re: Singles and suspension

Can I point you to Barry Luck's seminal articles in MRJs 18 & 19 on split frames wherein he described his solution to the traction problems in building, if memory serves, a Brighton G 2-2-2. As for the Chatham H I use twin beams on the drivers and have the bogie pivot as the third leg. The bogie...

Re: Wainwright H Class P4 conversion

You say that converting Studiolith wheels for split frames is difficult but are you aware of Barry Luck's article in MRJ 19 ? His method is to use a 1/8 reamer in the wheel socket hole until a i/8 axle will go in half way. The axle can then be pushed the rest of the way in and is a firm fit in the ...

Re: Wainwright H Class P4 conversion

Given the less than friendly relations between the P4 and S4 tribes in the early days I doubt that AG had any access to the former's products. Past history best left undisturbed. I also have some early AG wheels (for a Mallard Brighton K) which use almost the same axle/boss design as Studiolith. One...

Re: Wainwright H Class P4 conversion

A long time ago at the genesis of P4 the only 5'6" wheel available was actually based on the H class wheel specification. They were made by Studiolith, of not so blessed memory, and on whom Ultrascale had nothing in terms of waiting time. Also they were pretty good products have shouldered axle...

Re: painting paving stones and platform copings

If you are after paint mixing advice then I suggest that you get a selection of pots in your favoured medium, enamel, acrylic etc. One or two (or three) shades for each primary colour; red, yellow and blue, and try mixing them until you arrive at your chosen colour. Needless to say you may be in for...

Re: Colouring Sleepers

These days I use a combination of Indian inks and Humbrol matt grey/black enamels. I believe it is important to consider the combination of the colour of the ballast used and the sleepers as this will have an impact of the perception of the track. Personally I would always advocate the use of light ...

Re: Ballasting ply sleepered track

Rarely required in my opinion. Whether or not templates are used I invariably paint the track sub-base with ...

Re: Weathering rail and chairs separately?

In their book the chaps from St Merryn go into some detail regarding colours for trackwork.
They recommend different 'rust' shades for the rail and chairs. They do not, however, use plastic sleepered track of course.
