Here's a picture of the hydrofoil board I built this spring to test the monofoil (one wing) design. I also built/tested many two wing foils last year which use a larger main wing up front, fuselage and smaller tail stabilizer wing. The mono foil was surprisingly stable and lifted myself and the board out of the water around 2 mph and cruised around 10 mph behind the boat. We also tried a little wake surfing which was interesting.

The board, mast and foil use a shaped wood core covered in two layers of fiberglass then painted and waxed. This winter I plan on building a new canard based foil which has the main wing in the rear and a smaller stabilizer fin up front. I'm also working on a computer controlled/stabilized foil using a 3 axis gyro and waterproof linear servo actuators I built. In theory the foil control should come up to a predetermined height/depth Z then help dampen movement on the X, Y axis.

Merry Christmas

Thank you all. Have a great one. I took my crew paintballing. Not paint on my face. Heaps of fun but still recovering 2 weeks later.

Hi Guys.
Not even a day after escaping from hospital I managed to get to the Anson engine museum for our second annual small power engine rally, hence my rather disheveled appearance…. An old friend of mine caught me off guard a little and made this short video for posterity. Hope you enjoy it.

The engine behind me is a Crossley Diesel of 125 HP. The flywheel weighs in at 13 Tons.

The picture is of the Penultimate gas engine as mentioned.

Cheers Graham.

Ditto here Graham,  looking fine one day after your release  O0

They were surely jogging your mind there  :D

That's a monster machine in the background, hopefully you are not thinking of building that one on a 1 to 1 scale  :)

Great to see you up and at it again Graham!  Was back home a few weeks ago and had the pleasure to help start a F-M hit and miss. Quite a rig when you are standing next to it. Told him of you and your love for the old motor werks.
Be well.

Thank you all for your kind wishes, they are greatly appreciated.   O0

Sadly the curator was unable to start the big Crossley for me due to a blown gasket on the high pressure air start valve. Anyway, here’s a short clip of 13 tons of Iron coming to life….

Thay. I have restored 3 Fairbanks, Morse engines of my own over the years. They were one of the most prolific manufacturers in the USofA.

Cheers Graham.

Welcome back Graham, do take it easy, you may think you can do things but later you may pay for it, if you know what I mean.

Not sure atm if I will be over to visit in the uk, as you know not far from you, but if I do I will let you know. With one thing and the other here I am very busy, 73, and still burning the midnight oil and keeping my head down as we say, regards to Jules.
