Thanks for the Shake down /qualifying runs Paul. I think next year I'll revert back to a more normal guide set up. Last year the quality of (my 3D) manufacturing was pretty dismal so couldn't tell if it was the design or execution that caused the drama. This year hopefully it will hold together better, so it looks like it the design of the guide holder needs to be scrapped. Oh well!
That was the reason of me trying the design in this proxy to get a bit of trial by fire. R&D... racing and disaster, er, research and development!
