Re: Hornby King

The Speed Calculator on the High Level website is very useful and easy to use.

Look under 'Gearboxes' then 'Planning'. The link for the Speed Calculator is towards the bottom of the panel on the left.

Re: Steam up

Thank you, Steve. Having made two or three of these in development and now working on a couple of the final product, I still make mistakes (like not matching the two bits of the cylinder ends and the footstep slot not lining up) and find it important to think a few moves ahead if I'm not to get myse...

Assembling the cylinders - first, make sure you have the right bits! cylinder_3444crw.jpg I managed to get two S4 parts and two for either EM or OO. The S4 ones are the shortest. Do check you have them all the same length. You only need two of the parts with the rounded end, one for each side. These...

Next come the cylinders. These need thinking through if you are to make life easier later. There are quite a number of parts and more that are going to be fitted, 13 or so plus some tubing. The tube for the piston to slide in is 1.5mm o/d, 1mm i/d. Going further ahead, I have used 0.5mm nickel silve...

Steve, I made my handrails (including rectangular ones) using the BB handrail jig and soldering the ends together.

Re: best insulation material in loco?

The small self-adhesive foam pads for fixing things can be used. These may be too thick (often about 2mm) as they are but cut a piece to size then trim off the second adhesive surface to get the right thickness.

An example here on Amazon.

Sprung couplings

I have come to a crisis point with couplings. For a long time I have been using Exactoscale coupling hooks and their links but some stock, with rigid buffers, does not want to go round corners which are much more than a straight line. The clear answer is to spring the buffers and i m doing this with...

Re: Soldering Cab Roofs

Start at the top of the curve in the middle and work outwards.

Sounds to me like a good opportunity for some resistance soldering. Tin the inside of the roof, put in place and . . . zap. No need to add more solder. Tack in the middle, check alignment then work outwards.
