O B Bolton Triple expansion timing

[mickParticipant @mick65121]

Hi.

    I’ve been building the O B Bolton Triple expassion engine on and off for the past two years now, which I really must finish, as there are other projects I would like to build..   All the parts are made and the engine assembled, it’s just a case of assembling the timing gear and setting the actual timing.    The drawings were bought for me as a birthday presant  and as I haven’t used castings, but machined everything from cast steel, so I don’t have any build notes to refer to, that might have been supplied with the set of castings.

     Can any body point me in the direction of any web sites that would have the basic relationship of valves to pistons for all three cylinders, as a google search hasn’t come up with anything usefull.

Thanks.

Stuarts have a pdf of how to time their engines including their triple, may get you started
