Lathe change gear holder - 7x10 minilathe

This tray system provides convenient storage for lathe change gears for 7x10, 7x12, 1x14 mini-lathe gears, and the large text labels make gear selection easier. The trays include spaces for non-standard gears which are available in a related set of 3D prints (search for "lathe change gears").

The systems consists of 5 trays, and a set of hinge pins to fasten them together. Before assembling the trays, I recommend high-lighting the text for the gear sizes with a felt-tip permanent marker (Sharpie or similar). To assemble the trays, insert a hinge pin in the bottom tray and press it in until the groove in the pin sets into the ring in the hinge (using a small vise to press in the pin makes it easier); be careful not to lush the pin in too far or it will not mate with the next tray. With the pin inserted, add a tray on top and press down onto the pin. Rotating the trays back and forth can help to seat the pins. Continue to assemble all five trays.

Note that the prints provide some extra pins and pin "test blocks" - you can use these to practice inserting the pins if you like.

I did not provide a lid for the trays as I did not think one was needed,
