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...

Re: Anyone still use center drill Holders

To the contrary of most of the posts on this subject, for the last 30-35 years it would never occur to me to put a centre drill in a chuck! I have holders for 6 different sized centre drills for both lathes and have never had any any issues at all. Simply made each one from a redundant taper shank d...

Re: Locomotive stand design

The anti-gravity coal is a board with coal glued to it and loose coal piled onto top, the loose stuff wasn't the anti-gravity type!!

Re: Locomotive stand design

Went for a five mile test run yesterday that was uneventful apart from the need to get to the bottom of the boiler where a stud that helps to retain the grate had decided to fall out. So as an unplanned bit of maintenance the stand came into use again. This loco is almost 48" long over the buffers a...

Re: Locomotive stand design

To rotate for building or to maintain a completed loco I use a home made stand as shown in the pictures. The end with the gearbox is bolted to a steel bench (that is plywood lined on the top). The column is hollow box section with a "nut" ie a block of steel that fits inside the hollow section and i...
