Some time ago I made two Black Bamboo backed English Longbow stylish TD bows which, unfortunately, broke at the very beginning. Then a friend in Belgium contacted me and promised to send me some good bamboo as Christmas present. And so he did! I got one Tonkin and one Madake bamboo slice on top of three common Moso bamboo slices. I decided to convert those two hard bamboos to bows with Purple Heart core and Osage Orange belly. That Purple Heart I´ve bought some years ago and I succeeded to buy (under the counter) three pairs of European origin Osage Orange billets. I used Smooth-On EA40 for gluing the parts together and added some water buffalo horn pieces to convert the staves more like bows. I hope the photos tell the story clear enough.
