Re: Slide Valve Cylinder Castings

You will be better using a slot drill rather than an end mill.

Re: BR55/G8.1 Locomotive Project

Simple answer, no. I don't believe that there is any benefit to be gained in having on in our scale.

Re: BR55/G8.1 Locomotive Project

super7b: you are running a Nigel Gresley? This is so similar to the BR55 in almost every way, how she run? strong runner? what gauge is she (5")? I've run it for years on ground level continuous tracks and a portable track as well. Normally do 3 to 4 hours at a weekend on a 1.2 km track. Portable tr...

Re: BR55/G8.1 Locomotive Project

To make more work..... I removed the out and return shtr assembly on my Nigel and for fun made a concentric one. After about 5 or 6 weekends, passenger hauling over about 80 miles I took it out and refitted the original shtr. No empirical data to prove that it wasn't as good but just didn't feel as ...

Re: Winding springs

Many years ago whilst working a night shift in a power station the job left for me was to create a helical coil of 3/8" stainless tube. The coil carried boiler steam and was inside a cooling tank, in able that the boiler water could be sampled safely by the chemist. Laid alongside a really crap atte...

Re: Colchester Lathes.

I have a Student, as built in the video, still a brilliantly accurate lathe and a joy to use. 2 speed motor, metric and imperial screwcutting, Burnerd chucks, taper turning attachment. A bargain off eBay for £900 about 12 years ago. I imagine that the production techniques are identical to those use...

Re: Coal purchase

Timmy, I believe that Rosebud is the name of a mine in Montana, that produces coal of a dubious quality and hence the "Rosebud" grate was developed to assist in it's burning. Mine is basically a piece of 10mm thick mild steel, drilled with a 1/4" inch dia centre drill at 3/8" centres from the bottom...

Re: Coal purchase

On our side of the pond we are able to still source coal from almost everywhere, supermarkets sell it in bags for household use. So, no problem. The answer to the OP's original question all depends on the coal that you can reliably get and then learning how to burn it. There is no such thing as a ba...

Re: Choice of prototype

The OP asked for help in deciding on a prototype to build and most of the replies have been tending towards warning him against building on the grounds of cost/size/complexity/timescale. The OP appears to have the necessary kit and knowledge to do the job, after all it is only engineering, there are...

Re: Choice of prototype

If you want to build a model of anything, your heart must make the decision that way you will overcome any obstacle during the build. My choice, given my location, would be an A4. Look at youtube: https://youtu.be/K3Ku_Zwy39Y It's not difficult it's just a matter of size, go for it. Lots of this gau...

Re: Equalizer spring hangers

If you have to silver solder on the end of a piece of spring steel, push the steel into a raw potato right up to the end of the piece to be soldered. The potato draws the heat away from the steel just leaving the exposed bit to take the heat and the solder. Works every time and at the end of the job...
