ET: Engine (Twin) The Chain Drive Trials Comet

[Marcus Bowden]

As promised, some more photos, although Tim seems to have taken more than me, well he did get quite excited about the whole project.
No welded mods Oldhaven the inner c/case tab as you call it is a link plate that is crank shape but cut from solid alloy. The F106 is an F106/1 for G.F. It's a completely different casting .
Trevor, thanks for the info on Allan Screws / Bolts they seemed to be a new thing when I started in H.M.D. Devonport.
Running out of steam again.

Marcus,
What kind of ignition is used? Or are there twin sprockets used so that there is a chain drive to a standard magneto?

Apart from the weight saving, is there any real benefit........?.........How do you adjust the chain tension, or is it just fixed.

That would be real luck to have the shaft centers to be just right for no fractional links needed!

You could mount a tensioner block on the outrigger.
