Building an Improved Shavehorse

January 29, 2011

Recently I decided to give my son, a bowyer, my old shavehorse and build a new one with a few improvements.

The bowyer at the shavehorse

There are basically two styles of shavehorse, the “blockhead” or German (Swiss) and the “bodger’s” or English style.  The English style is a little lighter, affording the user a little more portability.

All shavehorses are designed to provide the user with a place to sit and a method of holding the work.  The “blockhead” design is usually fitted with fixed ramp.  The “bodger’s” style utilizes a floating ramp.  This feature allows the user to work a greater range of thicknesses without repositioning the clamphead.  On older “bodger’s” horses, the elevation of the ramp was changed by simply moving a wedge shaped block forward or aft.

 Most shavehorses are fitted with legs that are driven into tapered holes in the seat plank.  Legs usually have both rake and splay.  A simple way of boring the initial holes is to use a shopmade angle guide, once the “resultant” angle has been determined.

The next step is to use a tapered reamer to create the tapered hole or socket that the legs will be fitted into.  Using a tapered reamer can be tricky when rake and splay are involved.  The reamer I use is one made from a plan on Jennie Alexander’s website, greenwoodworking.com.  However, it does have one significant difference in that the first few inches of the reamer are cylindrical and designed to fit into a 1″ hole.  This means that this particular reamer cannot be used to ream a hole smaller than 1″, but it does help in maintaining the rake and splay.

The seat plank is held in the bench vise while the leg holes are reamed from the underside.

Okay, so after the ordeal with the reamer, the rest is pretty straightforward.

The finished product

 Well first, those of you who have been reading this blog for any time will know that the above picture was not taken in my shop.  But, rest assured, this is my new shavehorse (although, if asked, it may prefer it new surroundings).  Anyway, the clamp arms are 1 1/8″ x 2″ ash.  The clamp head is 3″ x 3″ ash with a 3/8″ wide V-groove on one surface and a 1/2″ V-groove on the opposing surface.  The are two positions for the clamphead on the clamp arms.  The footpeg/spreader is one piece made from hickory.  The ramp board’s position is supported by a pegboard that has been drilled with two rows of 1/2″ dia holes spaced 1″ apart.  A simple turned peg with a bit of a handle secures the pegboard.  A piece of 1/2″ brass or steel rod would work just as well.  The ramp board assembly is held in place with a wooden wedge.  The lignum vitae stop in the middle of the ramp board is used to keep longer workpieces from meandering to and from when you’re cutting chamfers or rounding edges.  The rear legs are 1″ longer than the front.  This allows the user to benefit from his or her own bodyweight (and helps to keep one from sliding backward into potential catastrophe).  The overall length of the seat plank is approximately 56″.   It may seem somewhat long to most first time users, but the benefit of the long plank becomes immediately recognized when you start working on something like the backpost of a chair, a bow or a canoe paddle.

Note the black fasteners.  My buddy, Les, explained to me that all you need to do is wire brush the most common, plated nuts and bolts that you can get your hands on, then paint them up with cold gun bluing.  Costs about $7.00 at Bass-Pro, Cabela’s, etc.  Hats off to Lester.  I’ll tell you, I learn something new everytime I turn around.  Who says an old dog can’t learn new tricks?

Back to work

January 22, 2011

Okay.  I’m coming out of my malaise.  The hiatus is over.  I can’t believe it.  I haven’t written anything for nearly two months.  No, I haven’t been sick.  I’ve been busy.  First, the holidays occupied a good bit of time.  But truth be told, I’ve been busy working wood with friends and family and it’s my intention to share the important part of those experiences with everyone who reads this rag.  You just gotta be patient with me.  Remember, I’m not a kid anymore.

Over the next few weeks we’re going to cover a lot of ground.  We’re going to talk about primitive bowyering, how to put together an improved shavehorse.  We’ll take a look at a beautiful little Roubo workbench that I had the privilege of helping my friend, Les put together.  Welsh stick chairs are on the agenda.  And, last, but not least, the Sidewinder Lathe project will be completed before the first day of summer.

So stay in touch.  Better weather and a lot more information is just around the corner.
