Hi,

I have just finished building a double acting engine with reverse for an Ellie Steam Tram.

A really good video which makes me want to get on with my Ellie. Is there any possibility of you posting your engine dimensions, bit difficult to see on the video.
Thanks, John.

Hi John,

I made only two drawings making the engine both of which are attached.

The dimensions are the same as Mamod use on their locomotive: Trunnion to axle 1.7/8" (48 mm used), Steam Port centres 1" (25 mm used), Stroke 3/4" (18 mm used). If their are any specific dimensions you would like please ask.

Take care Tony.

Hi John,

Sorry looking at drawing I used 1.3/4" trunnion to axle.

Take care Tony.

All the technical stuff's beyond me, but it's lovely to see the forum in action like that!
