"Beading wire", available from some craft shops might work. It is brass, very flexible (annealed?) and comes on a reel like cotton. But possibly too thin for this job.

Re: Fitting W irons

Where you have one fixed axle, then you have to be able to get this square to the chassis in two planes and get the ride height correct. In my experience, Slaters kits are not your friend here: the bearing holes in the mouldings I've seen recently are all over the place. This was for PO-wagon parts;...

I have diluted some old solder-paint (Eileen's product) with plain tap-water, on the assumption that the active part of the flux is not lost by evaporation but concentrates as the paste dries. It works as well now as it ever did.

If the mill is sending timber to a station on another railway, then the wagons of that railway could be back-loaded with the timber, but only if they happened to arrive on site loaded; I think it would go against the RCH agreements to send the other company's wagons empty to the mill from another st...

Thanks Noel. I guess that most of the class-B tank wagons had bottom-discharge gear which got in the way of the cross-shaft and the class-A tanks used the same brake-gear as class B for consistency.

Re: Knuckles's Wagon Building Log

I have fitted a cross shaft thing as I thought all wagons had them? I admit my knowledge here is lacking. By no means all wagons had cross-shafts in the brake gear. Early wagons generally had brakes on one side only, even if both wheels on that side were braked. Later, when the RCH insisted on brak...
