That was something that gave Bill no end of entertainment- getting the new skins to go from a flat to a curve!
Flippety-blinking right! In the first instance we couldn't get a piece for the new top skin out of a 2x1m sheet. Of course, sheets are supposed to be 8x4ft but for no good reason they've been shrunk so job-one was to weld a strip to the end of one to make it big enough. Flat is by far the hardest shape to make so that was the first trial. then the panel is mostly a double curve so that had to be wheeled (and you can't wheel some of a panel) until the fit-up over the formers was good but immediately above the headrest it had to be flat again because there was originally a hinge in there for the flip-up canopy and you can't have a curved hinge line. It was easy enough to gather the edge up with the shrinker to get it straight but that left a crown behind the gathered edge that then had to be shrunk out. It was a deep shrink going back about a foot into the panel and making it blend into the shapes was properly difficult. Almost as bad as sponson tops that go from flat on the inside face to double curves over the top then to a single curve on the outside. I'd have some good questions for that Norris bloke if I could get him on the phone these days!

Hehe Bill, you could contact him via a medium, now that would be a rollicking that'd be worth a listen!
I hope that if I'm a good boy you'll let me have a drive over to see her in the flesh one day before I start the filling/sanding process, as you know every pic from a different angle looks completely different & going back through the archives there are very few pics that are square on, just about every pic is taken from a jaunty angle.

Hi Mike, I've a looong way to go before I can start filling & sanding in the detail. To operate the linear rack that will open/close the canopy I've had to buy an Ardunio, programming that will be a learning experience. The only positive is that I'll be able to animate my DMC.

Those actuators are simple to program if you have the associated driver board. Are you going to control it via your RC transmitter ?
If you look up Brainy Bits on you tube he has tutorials using a rc controller to control a pan and tilt camera that could be modified to control you acctuator

Looks like I'll be having a brainy bits night, thanks for the info
I'd actually thought of him smoking a tab with a smoke generator, so when the canopy opens smoke goes everywhere, a bit like Cheech & Chong

If it's just a typical motor, you can plug it into one of the channels on the receiver and it will open or close on one of the toggle switches on the transmitter. Bit like retractable under carriage for a model plane.

Its a stepper motor with limit switches it needs a driver board and micro controller to work but the micro controller can take inputs from the receiver

you do know you could have got a micro servo (winch type) put a pinion on it and used that without anywhere near as much faff.

simply plug it in and go.
