Thanks one and all for help, suggestions and drawings......really really much appreciated.
Daniel, any chance of just a thumbnail dipped in ink diagram just so I can get my head around what you mean and picture it?
This sounds good as it won't be another accessory as such for the engine to drive i.e it won't take away any of the already limited engine power I'm thinking?
Jim ... I'll see if I can find an appropriate graphic to depict it for you on the morrow. Too late here to go looking yet tonight.
Heck, maybe tomorrow I'll simply try and catch up a bit on some of my postings here instead of working on any of the projects I've got going?!?!?
