So talk me through you vac set-up Bill.
I get the meter and the switch so the pump is not running continuously. I guess you have a check valve in there somewhere too. Tell bout the job of the tank if you would?
IceWind:
Hi Joe
That is a fine machine you got there.
Would it be able to cut some parts to make a skua clone? I ask this casue the skua seems to have tapered wings.
If you make a good price I'd like to have one. 8)

I have a one way valve just before the bag and one just after the pump (Aquarium shops).
My reservoir tank is one of the reuseable helium tanks you can get from Party Balloon shops. Anything which will hold the pressure is fine. Old calor gas cyclinder, fire extinguisher. I've also seen them made from Plastic pipe with end caps and then drilled and tapped for fittings

Hey Nando.
Sorry for the delayed reply. Generally tapered wings are not a problem. Big tapers and/or small tips can be a problem. A Skua would be fairly straight forward. I can cut you one but, will take a while as I'm waiting on some EPP and will be out of the county for November.
Do you know what Profiles used?? The Skua uses two different profiles by the looks of it. I'm sure we could get something that works pretty well.
IceWind:
Hey no worries!
Well I have no idea to be honest.
Sometime ago when I discovered the skua I tried and find the profiles, but I never got a proper answer.
I remember I found someone talking about that but when I looked for the profile I couldn't find it's values. I think it was SK-1!?!?
Looks something made up...
