Hornby CDA

Postby bigdaveadams1 » Mon Feb 22, 2016 4:31 pm

Hello all, I'm new to P4. I'm waiting for my ultrascale wheels to arrive for my 37s. In the meantime, I'm wondering which wheels I need to drop in to the Hornby CDA wagon? HAs anyone converted any of these before? Cheers for any info.

IIRC it's quite a tight fit between the axle gaurds - I think Jim S-W used Exactoscale wheels on some HAAs.

Nope but Phil did. They didn't work so they were binned for maygibs (14mm with Colin craig brake disks on alternate wheels). I actually think the older hornby HAA (and CDA) are a better starting point and easier to convert.

It's quite easy to fit Bill Bedford w-irons to the older model which improves them no end!

Was it the wheels themselves which were problematic, or the application of them? I was wondering (meant to ask you in fact until you said it was Phil who'd used them) about Exactoscale wheels for my fleet of BDAs as Gibson and BB wheels are a ridiculously tight fit.

Hi James

The problem was with the wheels as I understand.

Cheers

Cheers gents. So I'm after some maygibs for the CDAs then. I'll get on with ordering them ASAP!

I managed to fit some of the Branchlines nickel silver wheels in my CDA's on Wheal Elizabeth. They're not cheap but the are very good.
The w irons need thinning down a lot but as you can get a lot of lead in the body, there's no need to spring or compensate. Worked for me anyway.

Right so I've got to order some 14mm Alan Gibson wheels and some non riveted Colin Criag brake discs. Well wish me luck.....

If you get stuck, just stop at Gilberdyke next time you're passing - I'm sure Control will understand! ;)

I'm off to Toton all week! Maybe I could make a detour via Gilberdyke...

I think I'll pick my wheels up at York show and give it a go over the easter weekend.

Hi Andrew, how much weight did you put into the body? I know there's a big debate about how much weight is right. But if they work for you without springing or compo, then you're onto a winner!

I've just weighed all 3 CDAs and the scales tell me an average of 86g each. I don't know what an 'empty' wagon weighs.
I used liquid lead fixed with cheap superglue. From memory the hoppers were around half full.
Hope this helps.

P.s. I used the MJT etched brake disc inlays for the wheels.

A "box fresh" CDA weighs 60g according to my kitchen scales.

The current sale at Hattons has persuaded me to buy one of the 'new' Hornby HAAs, which I imagine are the same underneath as the CDA. Mine will be backdated to an original bodied HOP32 AB so quite a bit of work involved. Hopefully a suitable wheel swap will do the job but I have a feeling I'm going to end up doing a lot of digging out to get some Bill Bedfords in.

Cheers
