Re: Another B1 chassis

I'm sure you're managing fine, Howard. It's just occurred to me that I now supply lace pins so the valve gear can be assembled without soldering the pivots - I've described this elsewhere but let me know if you want more details. Ivan, many people get on fine with jigging the axles and the principle...

Re: Another B1 chassis

I have fitted Ultrascale crankpins to many Gibson wheels and, as you've discovered, it's important to use a minimum depth of counterbore (the 1.25 location diameter). The Ultrascale drg used to show it too deep but I haven't looked recently. I followed these dimensions on my WD and found, like you, ...

Re: Another B1 chassis

Yes, you'll see why I redesigned the chassis to get rid of the dreaded jigging operation that I could never get to work properly, either. Of course it all depends on what you're prepared to accept as clearance in the bearings but I detect that you don't like too much slogger, either, Mr Bellerophon....

Re: Turning a chimney

In my model engineering days I was told an advantage of the rear toolpost was that the cutting force is applied to the bottom half of the headstock bearings which would be less worn and therefore less prone to chatter during this sometimes challenging process when a wide cut is being made. They didn...

Re: CeeJay60's WorkBench

There's significant gaps in the generally available information on NER ND lattice signals which has long been a frustration, particularly width of decks. The lamps certainly were bigger than further south but the chimney was more modest than your drg. Have you seen John Wright's signal drgs in Model...

There seemed to be some real whoppers around the NER ND but I've never seen any specific information on these lamps.

Re: GWR 1361 CSB

Well I always assemble my valve gear with filed down lace pins and there's no solder goes anywhere near any of the pivots. Much safer. Forked joints, though. Biggest trap is not getting enough swing at the joints, particularly the pair at the top of the combination lever and the combination lever/un...

You'll see, too, that the LQ arms are longer and narrower than was "standard" elsewhere. Classic NER.

Re: 0-4-2 compensation

You might modernise the drive by dropping the ratio to 30 or 40:1 and, with a more modern motor, relying on a good controller or DCC for low speed control. A further reduction in noise could be made by separating motor and gearbox and connecting them with a Cardan shaft, motor mounted in bunker on r...

Re: Ralph's workbench

It would seem, on reflection, that by sticking a couple of bits of lead flashing inside each side of a Gresley 8w tender, I've probably created perfect condition for an inside-sprung tender to wobble - it's almost a large balance wheel. A loco with it's more central lump of lead is perfectly stable....

Re: Ralph's workbench

I've also found inside framed tenders try to wobble when they house the motor and normally use outside wagon type springs. Perhaps Adavoyle stock had more damping and possibly softer springs so it would have more effect. A sagging csb might be a better set-up as the wire would slide in the supports ...

Re: Dapol Stove R

My usual way of tackling such is to turn the axle holes into 2mm wide slots and fit springing. You'd also need to file the axleguard inside faces to give a min width of 23.5. Might such an approach be possible in this case? More details if promising. Mark Tatlow mounts his centre wheels on a tube to...

Re: Kyle of Lochalsh MPD - track layout

In the small photo above, the shadows give us something - the Black 5 seems to be quite close to the shed doors and there's a good working space in front before the turnout starts. Operationally, this is the important thing.

Some very exotic grounded bodies, too.

Re: Brimsdown-The last grand project.

Can I point out that your blades are still not opening far enough - only about 1mm. The prototype opening was 4 1/4" or thereabouts so you need almost half as much again for safety.
