First, I would like to point out that if I was doing this for a paying customer I would CNC the whole job ( get the staff to do it, but they want holidays???!! ) this is how I like to make patterns on my time off! Truth is, something like this I have trouble drawing yet a twostroke crankcase no problem.
The gue? is that two pot casting resin I showed earlier. Core has a waxing agent painted on. Use kiln dried pine, best for gluing or I use Armorboard, it's sort of like custom wood only much more glue used to make it. It's heavy and machines like alloy, leaves a nice smooth finish. Glues good too also very stable but don't leave it on your machines as it's abrasive.
If I do some more tomorrow I'll post pictures also.
2T, that ball valve throttle on the Bighorn works a treat!! I've been riding round the back yard with the laptop zippy tied to the tank tuning it, up to approx third throttle. I don't think the laptop likes it too much.
