I prefer maple or teak, though bamboo is harder than oak and comes from a sustainable source.

I was actually thinking of oak.  I can buy a piece of 1/2" x 5.5" x 12" oak at Lowe's, keep 1/2 x 1/4 inch aluminum angle to trim the edge, a pipe hanger to screw to the pegs.

I always wanted to put a pair of these on mine, but got a Boulevard before I did.

I did use this set of adapters

They do not have an adapter designed for the Savage, but I was able to create a little spacer block to use behind it( a rectangle of steel about 1/4"x1/4"x1" wit a couple shallow holes drilled to position the set screws).  I put on a set of wide HD pegs that felt better.

I then went ahead and bought a set of the floorboards( I got them from Dennis Kirk, so they were a bit less than shown on the Kury site) and put them on my Son's 750 Shadow, using the same adapters.  The 5 different mount positions plus the splined mount gives you a pretty wide range of positioning so there is a good chance to get something that feels right for you.

In the case of the Savage, I had to use a Dremmel and ream out the inside diameter of the adapter to fit the screw/pin in the Savage mount.

In the case of the Shadow, I had to grind down the sides of the adapters a little, so they soule fit the Shadow mounts.

In both cases I made the changes to the $20 mounts, rather than start changeing the bike.
