I use liquid solvent I think the bottle label says Plasweld or something like that. It's too cold this evening to go out to the shed to check the bottle. Just to make sure chairs will not come loose in the future, I press a small brass pin with a flat head into each fixing hole using a hot soldering...

Your railway looks great and it is nice to see the other Keith Massey Quarry Hunslet has a good home. These locos can certainly pull. The only time I have stalled mine (Linda - in blue) is when I have forgotten to take the brake off. It takes four people up a 1 in 50 readily. I don't have the rollin...

Hi The offset is related to valve lap. If the valve just spans the ports (that is there is no lap), then there would be no offset. The slip eccentric is arranged to be exactly 90 degrees ahead of the piston. This will work in our size engines but does not make the best use of steam. No problem if yo...

Well yes , in terms of size you are right. Gauge 1 and G scale use the same track gauge of 45mm. If you want to buy British standard gauge trains to run on 45mm gauge track then you need to be looking at Gauge 1 as was said earlier. British Gauge 1 models are usually built to 1:32 scale (that is 3/8...

Brian

There was an article on building a diesel electric with a glow plug motor in"16mm Narrow gauge in your garden" published by W H Smith in 2009, I think it was written by David Clark.

The design he describes was developed by Barry Reeves (Pilgrim Locomotive Works).

Maxitrack sell Chaloner with the wheels set for either 4.75" or 5" gauge. The wheels on my 5" Chaloner are not adjustable - they look as if they are a press fit. I suggest asking Maxitrak if they could make the wheels adjustable. http://www.davewatkins.pwp.blueyonder.co.uk/16mm%20rail...

The Sentinel was based on a very small drawing I found in a book on Sentinel Locomotives in the local public library. I used a single acting oscillator geared down 4 to 1 with a heavy flywheel. The flywheel is on a cross shaft which in turn is linked to the axles with chain. It uses Meccano sprocket...

Here are a few photos of the DeWinton. It is decidedly overscale for 16mm scale but would look ok in 7/8ths. The cylinder was originally single acting and later converted to double acting. It wore out it's first set of gears, I don't know where they came from but the larger gear had 'Primus' embosse...

Best of luck with Louisa. If you can find any reference to John Foulds's loco they might help with your project - he built quarry Hunslets in 16mm scale driven by a single cylinder oscillator.

Our latest 5" gauge addition ran on the BBLR for the first time today. The loco was built in 1979 to Don Young's design.

I have not heard of a water tube boiler in our scale. I suspect water capacity and hence duration would be low unless you were to fit a water pump. How about flash steam? That is point a gas torch down the middle of a coil of copper tube, with a non return valve and water pump on one end and the oth...
