Re: Stanier 3P - Judith Edge Kit

Yes, it was a challenge to fit it all in to the available height. Whether you could get a long enough spring beam within the available space could also be an issue?

Re: Stanier 3P - Judith Edge Kit

Hi Pete, I'd say it looks promising. This is the leading truck from my 1Co bogie, done as a radial truck (the real thing has a set of levers to make it rotate around some kind of virtual centre). Suspension-wise it seems to be along the lines of what you're suggesting. The radial top and bottom are ...

Re: Carriage ride height and springing

Oops, yes it's the cheap ones which stay coiled up (even when you unwind the ends out of the coil). I tried some as they were half the price - perhaps they're fine for guitars! You also have (in theory!), for a simple wire spring between two knife edge supports... (L)ength vs d is a third power rela...

Re: Carriage ride height and springing

The D'Addario strings are fine as a substitute for Ernie Ball, e.g. I use PL019 "High Carbon Steel Custom Singles" for 19thou (a size that EB don't make). (There are some cheaper ones that don't work so well for our purposes - a diagnostic is that they stay coiled up when you take them out...

Re: 14.4mm dia wheels

Hi Terry. Thanks for flagging this up again. It would be a great shame to lose these wheels. The 14mm ones are my 'goto' solution for 3'7" diesel conversions (but see below for a caveat), and a 'true' 3'6" coach wheel for MkIs too. There is the side issue of insulated vs live (I understand...

Hi Julian,
The trick is that you're using half of a switched diamond crossing to represent the turnout.

Re: On building track - straight onto the baseboard?

How was the foam fixed to the ply base and the MDF to the foam? All the MDF parts were sealed with builders' PVA diluted 1 water : 5 PVA. The ply was sealed with a coat of exterior grade varnish. Then the same PVA mix used to bond the foam each side. I did worry about the ends of the MDF base tendi...

The trackbed is as per the photo in my post of 23rd Jan throughout ('noisy' and 'quiet'), except there's no superelevation packing under the top 3mm MDF strip as it's a straight section.

Re: On building track - straight onto the baseboard?

but also a layer of foam between the main MDF and the MDF on which the track is laid I wanted to avoid having any deformable material there to allow precise control over the amount of superelevation. As has been noted in this thread, and elsewhere, it often all comes to naught anyway once the track...

Hi bordercollie - re. your thoughts, like this perhaps?... IMG_2138.jpg 6.5mm ply base, 3mm closed cell foam, 6.5mm MDF then 3mm MDF ballast strips. In yard areas, where no ballast shoulders or cant required, 3mm MDF over the 3mm foam will do. The oldest parts of this were done in 2007 and haven't g...
