A co-worker of mine asked if I could make him a glued-up block of hardwood for a specific work application. For my company’s yearly trade show (AAOS), they were demoing the amount of force that is applied to one of our knee products during a knee replacement surgery. The block of wood was to go between the knee joint and the load cell (which measures the amount of force used to insert the joint onto the existing leg bones). I made the block of wood 3 3/8 square and 1 foot long, and it was made with three pieces of anigre glued together with Elmer’s Polyurethane Glue (which is similar to Gorilla Glue). He finished it off by bandsawing the correct shape to fit the knee joint and coated it with a satin spray poly finish.
So here it is. My next tool. And it works too. I made a spokeshave. It cuts fine shavings with a small adjustment of the blade, easily done with two brass screws underneath the blade, after loosening the blade from its brass knobs.
The brass pieces were milled for me by someone at my job, who works in our prototype shop. I filed them a bit for the tool to work properly, and then sanded them down using progressively finer grits of silicon carbide paper up to 1000 grit. Then I used some polishing compound on a buffing wheel on my grinder, and made them very shiny. I then coated the brass with a bit of spray lacquer so they won’t tarnish.
The body of the tool was made from African Sapele, and the finish was two coats of tung oil, followed by Johnson’s Paste Wax. The blade was obtained from Hock Tools, and came ready for use. A very fine blade made by an expert, and the service from Hock was among the best I’ve worked with.
The tool plans themselves were from the #84 issue of Shopnotes #84 (my favorite woodworking magazine.)
