Hey guys I picked up a sample of Bamboo and did some test cuts to see if I liked it. Here are the results:
I have noted numbered areas on the images and commented on them below.
1- Notice the hold down screw split the piece down the grain. Definitely pre-drill and put in fasteners carefully.
2- The pocketed rectangle was done after breaking the edge with a 90 degree vbit (35 ipm). So I cut the chamfer and came back in after with a 0.25" up-cut end mill (50 ipm) for the pocketing. Everything looked really good with this cut. The edges with the chamfer are crisp and clean and there was no splitting.
3- The carving was done with a 60 degree vbit (35ipm) and looked excellent with great detail.
4- The profile pass was done with a 0.25" up-cut end mill (50 ipm) with a 1" ramp and 0.25 depth of cuts. You can see that the top split as you would expect when the bit went cross grain. You would really want to use a compression bit with this type of cut.
5- Note again how clean the chamfer and then pocket path looks.
6- This is where I intentionally tried to burn the bamboo while rounding over the edge. This material did not burn easily, I think it would rout very nicely.
7- I edge sanded the piece with my bench sander. It went nicely but I would caution that you can quickly remove material as it is pretty soft.
8- Note the grain split as the end mill came in and went out of the edge of the piece.
All and all I like the cut. The dust was very fine so that would be a caution. But with just a few precautions I think you could cut this material trouble free.
If anybody is interested I got the sample through Northwest Bamboo
. It is the 0.75" thick Stair Riser (horizontal lamination)
Talk to you later,
