Attempting to build those intakes from scratch over the last few months, I saved up all kinds of styrene stuff, chocolate boxes, empty scotch tape dispensers, and vac-pac plastic - anything that looked like it had a rounded edge with a 1/4" radius approx. I've been studying the intake shape of the Rhino RM32002 resin intake and cut a few paper patterns to experiment, -I coulda' actually been building something....
Low and behold, while digging through a precious heap of styrene [C6H5CH=CH2 futures are going through the ceiling, what with the price of crude oil] I came across a vac-pac for a bourbon-and-tumbler-glass-combo I got for Christmas, I think I was about 5 at the time.
Actually, it is a left over from a former hobby, whiskey sippin', back when I had a liver, and more than one neuron, C2H5-OH, ummmm.....close to vinyl benzene, come to think of it, but a lot less chewy!
So it looks like that vac-pac can be sliced-n'-diced to make about 80% of the intake in a single sheet. I'll post pics if it all works.
If it doesn't work, I won't post pics....... I'll be out trying to find another bourbon set with the right vac-pac with a 1/4 inch radius, and after I finish the whiskey, I won't much care about finishing this flugging build!
