Re: Shaving Horse Plans

>I recommend that you look at some pictures and build one that suits your fancy. I have collected several sets of plans, but have never followed the dimensions on any of them. I have built four shaving horses over the years, and started a fifth this past weekend. The first one I made is a behemoth made of cherry that stays in my shop. I make more compact ones to go on the road, and end up giving or trading them away.
Your idea to scale your horse up to your dimensions is right on. I believe most plans are scaled for hobbits. Get a 6' or so plank and mortise in some substantial legs so that the top is 20" or so off the floor. More is better. If you're a chairmaker you can eyeball appropriate rake and splay angles for the legs. You can probably do a good job even if you aren't a chairmaker. Don't get me wrong. Some of my best friends aren't chairmakers.
Sit on this bench, and adjust if necessary so that your feet can reach the floor.
Next, sit 6-10" from one end and extend your legs towards the other end. Roughly 4-8 inches back towards you is where the foot treadle should end when the dumb head is clamped down on the table (I call this the clamping position). Stretch out your arms like you're getting ready to pull on your drawknife. That's just about where the top of the sloping table should be, maybe an inch or so beyond (midway between your navel and nipples is a ball park height for the top of the table).
Now imagine a line that goes from a dumb head clamping down right near the front of the table extending to your outstretched feet in the clamping position. That line is where the center of the tiller board will be. Mark the bench where this tiller board goes, and mortise a slot for it. Before you elongate the mortise to allow the tiller to swing full throw, drill the horizontal hole through the bench at the exact point that the imaginary line penetrated it (this should roughly be near the center of your mortise). Fit in and drill the tiller hole, and hinge it through the bench horzontal hole with a dowel. Most tillers have more than one hole, so don't get worried about finding the sweet spot on the first try. Finish elongating the mortise to allow full throw of the dumb head.
Now fit your table. I use three dowels in the front, and three 1/2" wooden pins where the table meets the bench. Drill the three perpendicular holes in the bench. Cut three dowels that will bring the top of the table to the appropriate height . Set the table on three dowels set into the bench, measure and cut the angle of the bottom of the table. Set the table on the dowels and mark the locations of the holes on the bottom of the table, and set a sliding bevel to the correct angle. Drill the table holes (not through). Check fit, then glue the dowels to the table and bench. Drill the 1/2" pin holes through both the bottom of the table and the bench, glue and drive them in.
Do the mortise for the table.
The foot piece should be a thick plank heavy enough to make the dumb head open when you lift your legs. I make a sloppy mortise in the foot piece, and a long pin through the tiller to hold it on. If all else fails, a bungee cord or piece of ash can be used to spring it open. Springing open when you pull your legs back is important.
I hope that made some sense. Email me direct if you need help or encouragement.
