Nice design Cainguy, I like the squared tail better though, k2 style.
Pardon my ignorance but how do you determine the turn radius with snowcad? the 21600 sidecut radius means a 21,6 m turn radius or it has nothing to do with it?
p.s. hello everyone, as you can see from my post count I'm new here.

cainguy. I think building your cores in this way is more work, but is a good way to do it and leads to better torsional rigidity. I think also you will need to rip the bamboo into narrower strips to get it to bend and glue in this form. Make sure the bamboo lumber is vertical laminate only and don't change its orientation after you rip it.

Don't wait up, I'm off to kill Summer....
Thanks Redmond I like the square tail best too.
And thanks Falls for the info.
The bamboo is verticalll laminated and is 3/4" x 5 1/2" x 8'.
Is marking one face of the boards before the are ripped goood enough for orientation? or do they need to be numbered for some reason?
Since the boards are way too long so I was thinking of ripping some of the scrap ends and messing around with widths to see how it bends.
My first thoughts were about 3/8" and having five each side with sidewalls.
But to simplify, and since I won't be exposing any end grain in the sidecut I think I will go with six and carry the core out and have the bamboo for sidewalls.
The balance of the core will be Douglas Fir 7/8" wide running the length in the middle with yellow cedar laminated in the tip and tail to help lighten things up there.
It would be a shame to cover that all up....I think a clear top for the first pair.

Well I finally got the cores finished to the stage of profiling them using the planer. As has been mentioned it hasn't happen unless there's photos so here you go.
I sawed the bamboo into 1/2" strips and then ran them through the planer to 7/16"
The fir I had been hoping for didn't work out but my "wood connection" got me some absolutley gorgeous Yellow Cedar. It was a shame to resaw it down to 3/4x7/8 from rough 2x6. Here's the lamination hiding hiding behind my favorite STBR beverage. The lamination was done with cold cure and is bamboo(due to the lack of the fir) and Yellow Cedar.
I built three templates from hardboard. The extra 8 bucks for the painted stuff was sure worth it. The one in this shot is the second one for cutting the "sidewall" space out of the core blank.. I used an old piece of a shelving unit that is 1/2" square tubing to bend the radius and then used it as an edge for my flush trim bit in my router. It worked way better than the snocad print.
I used a piece of aluminum flat bar I had to make a drill jig for creating the templates from the master and to cut the cores using dowel pins to keep it all lined up. I flipped the template to cut the other side of the blank. There's that Hop Circle again...mmmmm
Once I had the cores cut I laminated the balance of the bamboo into the void I created. Three strips of bamboo on each side with cold cure again. The "sidewalls" are right around 1 1/4" with about 1/32" left for finishing all around. Also show is the template for the "full" core. I plan on using tip spacer but for only 7/8" where the bamboo ends. The dimensions ended up 184cm 158-131-144. Since I sort of used my el-hombres as inspiration and after a few bevys I figured el-retardo might be a good name.....boy they look rediculous.
Well the hill opens Saturday so skiing is going to get in the way of this but I will update you once I get the planer rig built.
