Hi guys,

I wanted to pick your brains about a project I am looking at doing. I want to make a cribbage board for my wife for Christmas and I would like to make it a little fancier than a slab of wood. I also want to keep cost down so I have a slab of bamboo stock in my garage/shop that I thought about using but I wanted to know if I could create a lamination with another wood to give it some contrast and visual appeal. I looked up some wood expansion charts but I didn’t even see bamboo listed.

I appreciate your help.


I love the smell of cedar in the morning!

I did a quick search and found a site that listed the dimensional change coefficient of bamboo as 0.00144. That seems to be around average for most other common species of quartersawn hardwood. Walnut was on the high end at 0.00190. A 4% MC change on a 4” plank of each of those species yields a difference in expansion of around .007 inches. So, they’re pretty darn close. I don’t suspect there would be a problem.

Note that those expansion coefficients for common hardwoods were based on quartsawn lumber. For flatsawn, the numbers can double in some cases. So, I would probably orient the laminations so your other species’ growth rings run perpendicular to the joint line wit the bamboo.

Edit : This is assuming this is actual bamboo stock, and not Plyboo or something equivalent.

Have your say...
