Snowboard wood core thickness

[heelside76]

Hey, I'm just starting building my snowboard but I was wondering if anyone knew what the thickness to flexibility ratio is on a snowboard. I want to make my board more flexible than not but I don't know how thick the wood core should be. I am using poplar for my core with one sheet of fiberglass

that should provide you with a bit more info.

pretty sure snowboard cores usually run about 7mm in the center.

yes thats right. I use 2mm at tip and tail and 8mm in center

How long is your running surface and what are the tip/waist/tail dimensions? One sheet of fiberglass? Normally there is one below and one on top.

Hey thanks guys. My board length is going to be a 161 with twin tips at 30cm and the middle at 26cm. But I am going to be using a fiberglass sheet on top and bottom. And thanks for the info about grafsnowboards.com, I tried to register on their site but I don't know if I've got a reply from the administrators yet. Thanks again.

I agree with iggyskier. Around .275 inches (7mm) would be ok for a 161
depending on how long your running surface is. Remember that stiffness
is a cube function so thickening or thinning a small amount makes a big difference in flex.

Thanks again guys.
