I made a xylophone for my grandsons second birthday. I had seen a old woodwright show where Roy had shown how to make a xylophone. The frame is red oak, the bars are also red oak. The mallets are made of sapele and popular. The frame was built and held together with dowels. The bars were cut then I used sawdust to find the dead spots to place the mounting holes. I used little squares of leather to float the bars above the frame. Here are some pictures and a short video.
Thanks for your time.
