Using scraps from bamboo floor job

I am involved in a job that is installing some high grade bamboo flooring and i ahve already laid claim to the sctaps coming off the job. Has anyone tried reworking the joint for glueup panels with the bamboo flooring? I have played with a couple of pieces and the material seems to present some interedting challenges on the cross cut. I thinking of building a tool box from the material and just wondering if I need to worry about moisture absorbtion and rust. I experimented with a piece by putting a piece of end grain in a 5 gallon of bucket with 2 inches of water. the water was gone within 2 hours and i found only about 1/64” in swelling in the piece. Any info appreciated
