CONSTRUCT-A

Equipping a high-school wood shop on a limited budget can be tough. And, buying lathe chucks, often costing as much as $200, is almost out of the question. To solve this problem, Dave Hout, an industrial arts teacher at Coventry High School in Akron, Ohio, decided to make his own chuck.

Note: To prevent the completed chuck from distorting after turning it to final shape, select apiece of kiln-dried, dense hardwood such as cherry or maple.

For added holding strength in securing the wood chuck to the metal faceplate, you may want to drill three additional mounting screws through the 3" faceplate

and into the chuck. Then, secure with an additional three screws.

And finally, to ensure that the faceplate remains centered on the chuck, Dave recommends leaving the chuck permanently attached to the metal faceplate.

Here's how to make your hardwood chuck

1 To make the chuck, you'll need a 3 ^"-square laminated or solid hardwood block that measures 4" long. Crosscut the ends of the block square. Draw diagonals from corner to corner on each end of the block, and mount it between centers on your lathe.

2 At a speed of about 800 rpm, turn the block round to a diameter of 3 3 /s" (we used a W gouge).

Using a parting tool, turn the tail-stock end flat (square to the cylinder) where shown on drawing A.

3 Remove the cylinder from the lathe, and chisel off the nub. Center and fasten the squared end to a 3" faceplate (we used 1" sheet metal screws).

4 Mount the faceplate/cylinder assembly to the headstock. Start the lathe and turn the cylinder to a 5 l A" diameter. Turn the tailstock end flat for a 3" finished length.

5 Using the dimensions on the full-sized End View drawing, pencil in the locations of the two recesses. Then, with a parting tool, turn the recesses %"-deep in the end of the cylinder as shown in drawing B. When making the final cuts to form the Vt"-thick
