Re: Layout Fiddleyard Planning - 4ft radius turnout

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

Hi Julian, Apologies if you've already looked at the link that Martin gave, but I was in exactly the same situation a couple of months back and found all the information I needed there. I am a bit more experienced with Templot so might have been able to make conceptual links that you're not, but I t...

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...

Hello Keith.

I've used these quite successfully on some of my sprung diesels.

Some shots of the sprung 'Peak' running on the circuit at home, with some unsprung Mk1s rattling along behind.

PenBits Sprung Bogies for Bachmann 66

Now on sale from PenBits, sprung bogie kits for the Bachmann Class 66. These have presented a real problem for 'drop in' rigid EM/P4 conversions, tending to rock about their centre axles. The long overall wheelbase has also led to the bogie frames catching on the underside of the loco over vertical ...

Re: Springing RTR 4 wheel wagons

Ah, the unit of Mike's that I mentioned is an inside bearing job - read too much into your OP! However, if you're in to outside pinpoints, his units 7.01 - 7.04 are designed for retro-fit to RTR and kit wagons.

There are also Bradwell's spring plates, written up on this forum here.
