Hey everyone,

 shaper cutter head

Saturday (May 09, 2010) in northeast Ohio was truly an ugly day, cold and rainy.

The previous week I had to make some casing for a round (radiused) top window. I had shot some video of the setting up of the shaper and cutting out of the blanks for the casing. The weather outside was so bad I just wanted to stay inside. I had not put any video together for a while and wanted to play around with some editing so I put together this video.

The video deals mostly with making the fixtures and jigs for running the material through the shaper. I made a minor mistake with the initial set-up and discuss the remedy for the problem encountered. Woodworking in general is mostly concerned with linear, two dimensional tasks, and our main tools prove that out. Carpenter square, table saw and fence, jointer, planer and even the other basic shop tools like the band saw and drill press are considered at their most accurate when straight and square. We are obsessed about it, heaven forbid your saw blade is out of parallel with you fence by .003 +/- of an inch. Round work adds a whole other dimension to woodworking and with it new problems and a new way of thinking, or visualizing your work. Don’t let that stop you the water is just fine, so jump on in.

The cutter head on the shaper uses high speed steel, corrugated knives (cutters), all together they weigh about four pounds. Spinning at 10,000 rpm, it is quite a rush the first time you turn the machine on and feel that wisp of air across your face, knowing danger is only inches away. It does quite a number on your spincter muscles also.

And for you hand tool people at about 35 min. into the tape I use a compass plane to finish the blanks. The compass plane is a kind of unique tool, a unitasker, good for only one thing, but it does it so well that you might consider picking one up if you ever have the chance.

Hope you enjoy and maybe saves you from a mistake!
