Re: Purbeck 1/3rd Scale DG800 Build Thread
Phew, all is well!
The two glassed surfaces (the fence along the fuselage and the seat tub sides) released perfectly from the mylar between them. The sellotape covered carboard was a bit more sticky but also came off without any damage!
Then I trimmed the fences and tube sides and did a quick check with Mr Pilot - all is well...
A bit of finishing and painting to do and then onto the instrument binnacle.

Amazing job Simon. Is it just the over centre pressure from the gas strut that keeps the canopy closed?

Re: Purbeck 1/3rd Scale DG800 Build Thread
You're all very kind!
Yes Andrew. I roughly worked out from the geometry of my hinge that when it was closed the gas strut would be facing below a direct line drawn from the strut base to the canopy hinge but that when it started opening it would be on the other side and therefore start creating a positive opening force.
The mock up hinge I showed earlier in wood allowed me to confirm it would (with various different hinge strut mounting points) and finalise the design.
I'm not relying on the gas strut to keep the canopy closed by the way, I also have a conventional sliding canopy locking mechanism (which admittedly begs the question on why I did it anyway!)
It was a right pain in the proverbial doing it but I'm kind of glad I did anyway!

Looks a bit special Si! Would be really good to see all 3 flying this year....
TERRY, get your finger out!

Simon,
Good progress
BTW a friend at Cambridge Gliding Club has just bought a full-size DG 800S (G-CJJH). If you want pictures rather than model it on a Swiss glider let me know.
Regards,
Robert (ASG29 W8)
