Post 9: Building the basic cello frame

   This morning, I cut the four square tubing sections roughly, drilled holes for the two long bolts, and assembled them temporarily. I cut the curves as best I could on the band saw, and finished them on the big and small belt sanders:

   Now, I can lay that frame on top of a piece of 1/8" aluminum and draw the plates that will stiffen the frame. I cut them, sand them, and drill them  aped together so they match perfectly. I clamped them to the frame and drilled the holes in the frame for the countersunk oval brass screws. I tapped the holes for 8-32 screws.
