Re: CSB for a Single Driver

Very impressive Jeremy! My singles will only be required to pull Roxey Stroudley LBSCR 4/6 wheelers, or Branchlines Billinton 6 wheelers, or a couple of my own Stroudley or Billinton kits (omitted from their ranges). The Roxey ones have had their horrible inside bearings replaced with my own W irons...

Re: CSB for a Single Driver

Been watching this thread carefully I have already rebuilt the chassis on my GCR 422 Single. When I built it many years ago I sprung the wheels although not CSB style I used Alan Gibson sprung hornblocks. The basic problem was tractive effort, it struggled to pull the tender. I got round it by chan...

Loctite

I thought this might be useful for other modellers: Just for the record: I have contacted Loctite directly today to ask about the most effective anaerobic retainer for us as modellers to use - I didn’t actually state that we are 4mm / 7mm scale modellers (!) - but i did mention gears of brass being ...

Re: CSB for a Single Driver

Well, I do have several singles to build! Thought you might like to see the actual prototypes! One is already built, though the chassis is not yet fitted with its motor - the unique no203 ‘Sussex’. 203-Sussex-a 2.tif Then three or four other singles - the small cylindered 325 ‘Abergavenny’, the larg...

That’s a very good question! That’s the length they come from Ultrascale. I’ve been tempted to cut it in half and just order another worm wheel for a second set at reduced price......!

Although some time has elapsed since the last post (!) on this thread, I’ve been away, but having reread it, Will’s comment about a tender drive interests me. Because of this same adhesion issue, having passed E.B.(Exclusively Brighton) Models on to its present proprietor Ian MacCormac, I designed w...

Re: CSB for a Single Driver

Just checked, and the G singles wheelbase was:-

8’ 0” + 7’ 9” for the unique large boilered ‘Grosvenor’ (with 6’ 9” drivers).

The same for ‘Abergavenny’ - the smaller version, with 6’ 6” drivers.

And 8’ 0” and 7’ 11” for the ‘production’ G class.

Re: CSB for a Single Driver

An excellent treatise!

Just one small point... 1/8” axles are used throughout Stroudley’s G class, that Will correctly deduced I was enquiring about, even on the tender, as it uses the same wheels as leading and trailing wheels on the loco.

Incidentally, which motor rpm is recommended as a general rule, bearing in mind all the mitre gears are 1:1?

Thanks Keith and Dave for those observations. I can’t quite locate the model of n20 motor and gearbox - presumably it’s an eBay Chinese one?

Thanks for your thoughts Gents. Yes it’s just a set up to see what it looked like a few of years ago when checking the etch was centring the gears correctly. I didn’t photograph the revised model, which sticks to the same principles but has quite a few amendments. I asked Chris a couple of years bac...

Re: Singles and suspension

In MRJ 21 page 55 Allan Sibley described how he arranged the drive for a GWR Dean single. The drive was on the trailing wheel via an intermediate shaft geared to the motor and the "driving" wheel was weighted and allowed to go along for the ride. This arrangement had the advantages of 1) ...
