Question for the Snowboard Builders

[Sherpa Burns]

I am planning on building 3 snowboards this Spring to give as gifts for my 3 groomsmen in my wedding this summer. Trouble is, I ski and I have only made skis.
I had my local cnc shop route me out a base and core templat that I modeled after the Never Summer Raptor (just made it a little larger, 165 length, and about 1cm wider throughout).
My question is, what is the typical or tried and true core profile? Core material will be bamboo. These guys are all fairly large (190-220lbs) so im thinking I want these to be a little stronger than average.
Any help on the core profile dimensions would be great.
Thanks,

never done it but maybe 2.2-7-2.2

That's about right. If you're modeling after a specific board (The Raptor) then just measure the thickness at middle and ends, note the profile drop for your .stl file (or whatever you're using) and then depending on your materials, subtract 2 to 4mm, right?

stock cores from snowboard materials have a pretty tried and true basic profile that works well for most boards. 2-7.25-2 on a 165 is about right what they're using according to my notes. They taper down over a pretty short distance (I think 10-15cm). Tapering over 20-25 cm gives you a smoother flex IMO.

Thanks much. I guess I'll use the dimensions from the snowboard materials cores and then run a few extra carbon stringers to make sure its tough enough.

Hi. I am large man(200lbs +) and have build some snowboards for me. First one was 2mm - 8mm under front foot - 8mm under rea foot - 2mm. 20oz triaf under the core and 20 oz over the core. As the result - prety good stiffnes, but a little soft for me. Second one I added 3oz carbon UNIdirectional under the core - perfect stiffnes for 200lbs+ man.

Profiles sound about right, defintily a stiffer board.

I woudl be careful with the wdith...addding 10mm is HUGE. Unless you're bigfoot and your groomsmen are the Yeti, the abominable snowman and a clown, I'd leave the wdith and sidecut exactly where it is. Never Summers tend to be a mm or so above the average as it is.
