My buddy Bruce used to do high quality aluminum casting and the way they do it in-house is they use that lost wax method to make a sand molds they vibrate the bins of sand to make a coating they melt the wax out and then use that as the mold now the only thing they do that really makes a difference and high quality is that the keep it heated and under pressure when it's cooling so it's slowly cools and it creates a crystalline structure that which makes it harder and more durable...

Not remember you going to sleeve it with an iron sleeve and then if you can find a place get it nicka Saledsalad after you port it really fancy...

Alex and I have both been looking into doing the Nickel Silicon Carbide plating ourselves. I've been producing very hard plating but still need to work on the aluminum adhesion. Tonight I tried replacing the silicon carbide with Boron Nitrate. Still really hard but more slippery.

Well boys and girls, I have news. This weekend I attempted to plate my latest cylinder. I had been doing a number of plating experiments and learned that the initial step of bonding to the aluminum, can be tricky. I had gotten it down to where I was happy with the bond so I went ahead and plated the cylinder. This was a nickel silicon carbide plating. I was diamond honing it to the proper diameter when the plating let go. The bike was being set up to compete in a land speed racing event that is held in Maine in the middle of July. It is possible that I can cast a new cylinder, get it plated, finish up the fuel injection, and make some changes to the aerodynamics in time for this meet, -- or -- , I can set this project aside and work on my newest project.

I chose the newest project.

You should put that motor in your ped . You might achieve some kind of speed record . LOL

Re: Failure to cast a cylinder

If you're running outta time there's lots of plating companies.

Don't know if diy is your only self imposed way here

Not so much that. I wanted to see if I could get a single speed 50cc into the 70mph range. I hold a course record of a few hundredths shy of 63 so there's that. More importantly, I have wanted this particular type of airplane since they came out in the 80s and I now have one in my barn. I will probably return to land speed racing, but I'm going to give it a break right now while I pursue flying.

Re: Failure to cast a cylinder

i know squat about airplanes but that looks like a heavy duty money pit. what has to happen to make that flight worthy?regardless, your a bad ass for going in on it and i dont doubt that you can make it happen. just make sure you invest in a good parachute. ;)

Re: Failure to cast a cylinder

You've wanted one since the late 80's, well you have it now. It's in your barn and not going anywhere. Crack on with the moped and make us all proud ;-)

Re: Failure to cast a cylinder

ah man that thing is pretty cool, at least you're still messing with two strokes! looks kindof like a rotax 583?

Rotax 582.
