I’ ve been making a twin cylinder diagonal steam engine with Stephensons valve gear.by Edgar T Westbury. However I can’t get the valve gear to work correctly, has anyone got the same engine and had any problems. I can run the engine on compressed air but would now like to make a boiler has anyone any plans. Once complete I intend to place the engine into a Director class paddle Tug model

Westbury designed a boiler suitable for his diagonal engine. It is drawing M10 - Trident Major Internal Flue Boiler.

This is a large engine and should be driving paddles much larger than those shown. Should be capable of driving a six foot model. If you manage to get it into the Director as drawn it will probably sink!

Steam is POWERFUL as I discovered with my first steamer. Lots of folk have built Stuart Double 10's with the intention of fitting them in three foot long craft, but it really doesn't work.

Unless you are intending putting it in a large model, I guess the best bet is to make a nice job of it and put it on a shelf where you can admire it, then build something much smaller.

Thanks for the information on the boiler, are there some plans I can get. I'm new to this computer stuff so I may need to get my son to help me. I've scaled up the tug plans from some I got years ago, it's approximately 4.5 ft long and should suite the the size of paddle wheels. It will be nice to see it work under steam if I can make it work.

It looks as though the boiler drawings are no longer available. However, I'm sure I have a set somewhere. If you like to send me your address, I can post them to you.
