As I quite enjoy perusing old plans, and rendering them into the CAD software I have at my disposal (for laser-cutting at a later date) I thought I'd get cracking on this fine little high wing semi scale specimen as I have a little time on my hands at the moment. I recall that the design appealed to me back in the 70's, as I particularly liked the tri-undercarriage. I always hoped for a field takeoff, but alas, the wheels were too small for our grass strip!
So this is a jpeg of the works so far:
I'm pleased with it so far, looks pretty much like the original plan, more or less. I have stuck to the original material specs for fuselage sides, stringers, reinforcements & tailplane, but I thought the nose reinforcement pieces were a tad too thick, so scaled them down accordingly.
The 1/8th sheet cut-out at the bottom took some fiddling around with, but I think I got it right in the end, the undercarriage is bound and epoxied to a piece of ply that sits between the two marks on the underside. Hopefully I'll get the tailplane and the wing ribs done tomorrow, which will pretty much be it for now, at least until my Sharkface has seen some action at any rate!
P.S As mentioned elsewhere, this will be a 3/4 size rendition of the original plan.
A little more progress, but work and other 'commitments' have made it a little tricky. Here are some jpeg images of the cutting files, for 1/8", 1/16" and plywood parts. I think it's about ready, apart from the wing rib profiles, which are slightly more complex than the Sharkface, as the Santa Maria has tapered wing tips.
Once done, I'll make them available for anybody who has access to a laser cutter or other cnc device.
God managed without machinery, but most of us need a little help
Okay, I think I've finished numero 2 in my series of vintage laser/cnc cutting 'kits'. I use the word 'kit' loosely, as although you'll end up with a nice box of perfectly cut bits, there should still be enough assembly to satisfy the scratchbuilder in you!
