This is a storage box to keep my old fixture and it’s new collet and bushings together. It is made from 1/2” maple plywood. First I lock miter cut all the edges and made it into a closed rectangular box. Then I cut the contour on the bandsaw and started designing the components to hold all the accessories.
I made this grinding/milling fixture back in 1969 and I used 2J collets from the Hardinge lathe at Western Electric in Montgomery , Ill. It was used to hold pieces for grinding or milling 2,3,4,or 6 sides very accurately.( The 4th photo shows it in use). When I left there in 1970 I never had access to these collets so the fixtures was stored in this leopard rag all these years. I had several occasions that I needed it but did not have any collets. I went on line to buy a set and got a shock. They were from $63 to $104 each!!!!! So I got some steel from my good friend , George Armstrong, and made a universal collet and nylon bushings to changes sizes. Now I needed to keep all this stuff together and this box was designed to do that.
I used two small pieces of maple to make a holder for the wrench. There is a dowel in the center to store the fixture on with the collet inside and the back nut on.. The two lift out side racks are cherry and bored to hold 16 bushings like poker chips. I only have 5 bushings so far. If I make other special sized bushings, they could be made of hardwood just as well as nylon. The handle on top is maple also- it is screwed and glued onto the lid. I added a brass locating pin in front at the seam to keep it aligned side to side in case the hinges would not be set exactly right. I really did not need it. There were no drawings for this- just a sketch that the inside of the box had to be 4×4 1/2×8. It was a design on the fly project.
The box is finished with Zar cherry stain and spray clear satin finish.
