HAPFO

Copying Lathes

Advanced wood copying lathes for custom turning a wide variety of parts, especially long thin parts such as those required in stair and chair production. An adjustable ball bearing back rest guided directly in front of the cutting tool makes this possible by reducing vibration of the workpiece and the part is completed in one pass. HAPFO lathes, made in Germany, are available in a variety of sizes, 45 to 78 inches between centers, in both manual and automatic operations.

Jointer thicknessing-another design w

Wooden leaf spring

Spring raises workpiece for thicknessing.

The design presented here converts a jointer to a true thickness planer, and it takes just a couple of minutes to make the conversion. On a regular thickness planer, the work is fed between the cutterhead and a flat bed. My method's principle, if you imagine a regular planer turned upside down, is the same: the workpiece is raised by wooden springs and pressed against a rigid overhead reference plane above the cutterhead.

My reference plane is laminated from two pieces of %-in., 9-ply birch plywood. It is held above the cutterhead by an assembly of aluminum spacers, threaded rods tapped into the feed table, and wing nuts. Another necessary component is a flat leaf spring, which presses the workpiece against the reference plane until it begins to ride the outfeed table. I made the spring from two 2%-in. wide, Ya-in. thick strips of oak by steam-bending the last 4 in. of the strips. A simple cleat that hooks onto the end of the jointer table holds the spring in place.

The dimensions of the reference plane are not critical—an 8-in. square is about right for a 6-in. jointer. Wax the underside of the plane to reduce friction. I made the spacer strips by epoxying layers of Ya-in. thick aluminum strips together to form pairs of %-in., %-in., XX-in. and Ya-in. spacers. The spacers are notched so they can slip onto the threaded rods with the reference plane in place.

To use, joint one face of all the pieces you are going to plane. Select spacers equal to the thickest piece plus another XX in. for the spring. Bolt the assembly in place, position the spring, and back the infeed table down until the thickest piece starts to cut. Plane all the pieces at this setting before lowering the infeed table for the next cut. Continue until the final thickness is reached. —JE. Keister, Cincinnati, Ohio

Collet chuck for turning miniatures

Workpiece

This collet chuck, adapted from a drill-press attachment, is inexpensive but effective for turning miniatures on the lathe. To make the chuck, purchase a drill-press attachment called a col let chuck with heavy collar (Sears part o. 9-24672). The holding collar that fastens the device to the drill press is not needed on the lathe. You'll also need an adapter pin with a male No. 33 Jacobs taper on one end and a Morse taper on the other end to fit your lathe spindle.

Fit the chuck to the lathe, then tighten the collet on a short length of %-in. dowel, and you're ready to turn. A set of bushings that comes with the chuck will let you turn XX-in. and %-in. dowels in addition to the nominal %-in.

Quick tip: I prevent joints from sliding around during glue-up by driving two %-in. brads halfway into one inside face of the joint, then clipping off the heads so about !4> in. protrudes. When the joint is assembled for clamping, the two little spikes bite and hold firm. —David G. Mensing, Tucson, Ariz.

All-wood adjustable shelf bracket

This easy-to-make shelf bracket ensures accuracy because both pairs of shelf-height notches are established with one hole. To make the bracket, clamp two 1x2 strips together and drill a series of holes down the centerline through both strips. The holes will set the spacing between shelf locations. Now rip each 1x2 on its centerline to produce two matching brackets for each end of the shelf unit. Install the brackets in the carcase and cut several %-in. square shelf supports to fit in the notches. Round the ends of the shelf supports to match the half-round notches in the brackets.

A Course In Wood Turning

A Course In Wood Turning

Ever wondered what wood turning is all about? Here are some invaluable information on how to make beautiful items out of wood! That one little strategy from A Course In Wood Turning that I implemented not only worked, but the results were completely astonishing. I had never seen anything like it! Now, keep in mind that I had tried a lot of other products up until this point. You name it, I probably tried it! That’s how desperate I was to improve my skills with wood turning.
