I made it at the TechShop (www.techshop.ws) in
The final project (main image shows a prototype) requires a large number of wine-bottle corks to be cut transversely into two nearly equal lengths. To avoid cutting them individually, this stage involves building a jig to allow 50 corks to be cut in one operation.
The corks are about 1 7/8” long by 7/8” in diameter, or just under that. The sizes vary slightly. This jig will need to accommodate them snugly. (The dimensions given are those used in this project – different ones may be used if convenient, but they will need to be calculated to fit the corks.)
How the corks are used in this project will be described separately. But this section will provide for any project which needs cork segments.
- Plywood sheet ¼” thick, 1’ wide by 2’ long.
- Wooden board ¾” thick, 8” wide by 2’ long.
- Wooden lath for spacer 3/8” thick, 1½” wide by 8” long.
- Wood glue.
- Four wood screws 2” long.
- Two ¼” steel bolts, 3” long, with wing-nuts, and 4 appropriate washers.
- Table saw.
- Drill press.
- Band saw.
- Belt sander.
- Hand-held electric drill with sander attachment.
Mark-up one of the halves for drilling cork-holes. Omit one hole at the end to ensure orientation. There should be three rows of holes (17, 17, and 16), the centers separated by 1” laterally and lengthwise.
Cut board lengthwise with table-saw to make the equal halves.
Clamp two boards together and drill all holes 7/8” diameter through both boards.
Take the ¼” plywood and mark up for the backing and alignment pieces. These can be a little over-sized as they will be trimmed later.
- Backing pieces: 4” x 23”
- Alignment piece:2½” x 23”
Cut plywood into the marked pieces.
