During the last week my family and I rode mules to the bottom of the Grand Canyon to stay at Phantom Ranch. (John, you’ll be happy to know I didn’t fall into the canyon so you don’t need to look for a new business partner.)
I’m granting myself a few more days of radio silence, but I will return the workshop and blogging later this week.
Fig. 1. What the finished plane looks like. The exact length is not important, but it should not be much shorter than 9 ins. as it may be liable to dig in. This plane is 10 ins. long with a 1-3⁄4 in. cutter.
Two ways in which the plane would come in handy are shown in Fig. 2. In the one the plane is smoothing right up to an internal corner, and in the other is a stopped chamfer in which the plane could work right up to the stop. Many other uses will suggest themselves— such as trimming a stopped rebate.
Fig. 2. Examples of work for which the plane is suitable. Note that a strip of metal is placed beneath the thumb-screw to cover the slot in the cutter. The knob is either square as shown or it can be turned.
It will be realized that it cannot be used in place of the more normal type of plane; it would dig in and fail to produce a flat surface. Furthermore, it could not be started. It is suitable only for working into a corner after the main surface has been planed. The great secret of its successful use is to press well down on the handle. Only in this way is it possible to avoid digging in. Then, the cutter must be set fine—sometimes without any projection at all—and gradually fed forwards. It usually happens in this sort of work that the corner is high, and that is why it will sometimes cut when there is no projection to the cutter at all.
Fig. 3. Side and front elevations and plan. Sizes can be taken from scale.
Fig. 3 shows the plane to scale. The main stock which should be of hardwood finishes 10 ins. by 1-3∕4 ins. square. Allow the width a trifle full for trimming and cut the front to an angle of 20 deg. Also shape the back. Finish neatly with a chamfer. The clamp is 4-1∕4 ins. by 1-1∕ 2 ins. by 1∕ 2 in. It has a hole and slot cut through it to enable it to be slipped over screw head and pushed forward into place. The thumbscrew can be any convenient screw, the hole for it having the thread forced in it. Bore a hole to the narrowest part of the thread and force the screw into it.
American sycamore (Platanus occidentalis) has long been one of my favorite woods. I first started using it about 2001 when Frank Miller Lumber started offering it for sale at ridiculously low prices (less than $2 a board foot).
At the time I was building an addition on our house and saved hundreds of dollars by using sycamore instead of hard maple.
It’s a wood that commands respect. Your tools have to be sharp and well set or you’ll just end up with a mess of tear-out. You have to insist on quartersawn stock – flatsawn sycamore moves quite a lot and looks like cheap Asian plywood. Quartersawn sycamore is beautiful – I call it “redneck lacewood.” Sycamore’s grain is interlocked, so it is one of my favorite woods for chairmaking, especially seats and armbows.
But recently it’s become hard to find in my area. Frank Miller doesn’t cut, dry or carry it anymore. Our local lumberyard never has it. Forget the retail outlets such as Rockler and Woodcraft. They just sounded confused when I called to inquire.
After striking out at my usual haunts, Megan Fitzpatrick and I hit the road last week to visit some rural sawmills and lumberyards. Between us, we called or visited more than a dozen places and came up empty-handed until I called C.R. Muterspaw lumber, which is an hour north of me.
They had four or five boards of it. I hopped in my truck and raced toward Xenia, Ohio.
It took about an hour of digging through the stacks at Muterspaw (they were very good sports), but I found four spectacular boards of the stuff for about $5 a board foot. And I’m using them to make a Welsh stick chair.
It all left me wondering: Why has sycamore disappeared from the local market? It’s not a rare tree. Platanus occidentalis is a junk tree around here and grows to a sometimes enormous size in low, wet areas.
I’m going to ask around. If anyone knows of a good source, speak up.
The Romans used the square to layout the ubiquitous half-circle arc flutes along the length of their temple columns. You can too: Just set alignment pins at the start and stop points; hold the square against the pins; hold your marker at the apex of the square; and scribe away!
One of the advantages (or curses) of studying a lot of old furniture is you can feel certain designs tug at you as you work on a piece. This weekend I got a little time to work on this Hall’s Croft chair and I could feel several other similar chair designs tug at my brain.
I love quartersawn sycamore. It’s a junk tree but, when used properly, is beautiful and stable (enough).
First, I abandoned the pine seat and switched to quartersawn sycamore for the seat, arms and crest. The spindles are hickory and the legs are beech. I selected the stock so I could use an oil and wax finish instead of paint or a dark pigmented finish.
I changed the seat profile slightly to make the front corners sharper. I altered the leg shape a bit. But the biggest change is going to be the crest rail. Instead of the “three holey mountains” of the original I’m going to use a different shape I’ve been experimenting with. It uses rived stock that is somewhat triangular in cross-section.
When I offer it for sale, I’ll give the customer both crest rails and let them decide which they prefer. Or they can swap them out when they are feeling sassy.
