Very Cool. Im starting grad school this fall. If i don't manage to cast this thing by then i was hoping to make friends in the schools foundry and cast it there.

What will you be studying in grad school? My BA is in industrial design and my MFA is in glass. Most art department foundries like people who are driven and who are there to get work done. I have a lot of credit hours in the foundry, bonded sand and investment casting bronze and aluminum. AND a bit of cast iron.

I have a BFA in graphic design. I will be getting a MDes in industrial design. What type of glass work were you doing? I transferred into art school with an AA, which meant i got to take a lot of electives; most of them were glass blowing credits. I really miss it, nothing like throwing around 20 pounds of molten glass. Thats also where i got my first taste of investment casting, but i didn't really get into it until a couple years ago. I am really looking forward to having huge facilities to make cool shit in again.

I did a lot of pipe work. I have a big pipe that let's me work with over 20lbs with ease, it even has an inconell head. I have had success using the glory hole in reduction to strike some of the German colors back the there metallic bases. Most of the Kugler blues are based on copper sulfate and I found a way to make them appear as metallic copper. That was a long time ago, most of my time is spent at the cnc these days.

So much for memory. That was 46 years ago. We had it in junior high and high school. It was good for us. They don't have it now.

vic,

have you paid much attention to the brothers valtoron?

Yes I have seen their stuff. very impressive craftsmanship. That bike is actually the one that made me think a 750 twin was kinda cool.

they seem to have a bit of a bias towards kawasaki in there builds .

some of the monocoque bodies are awesome :evil:

How could anybody not love a 750 scrambler? It is everything the old British dirt bikes wrer, except unreliable :whistle:

No tickling leaky Amal carbs, no left-side kick starter and right-side shifter, and an electrical system that actually has electricity in it, rather than smoke!

I did a little bit of frame bracing. Im debating putting the brace in from the back bone to the subframe. there is loads of room between the tank and seat here, and i think it would benefit by it. Thoughts?

can't hurt :evil: !

I mounted a road rider on the rear wheel, and dropped the bike off at my buddies shop. I just made him a seat for his BMW project, so for trades he is going to make me some wheel/swingarm spacers, and help me finish the swingarm fabrication. Cant wait to see the swingarm finished! heres a pic of his beemer.
