I did a couple of presentations last weekend at Fine Woodworking Live; a seminar put on by the magazine. It was a sold-out affair, and seems like everyone had a good time. With the magazine staff, the presenters and the attendees there were close to 300 people there. All trying to consume as much information about woodworking and furniture-making as possible.
My talks were 90 minutes, and it’s hard to cram everything I know into that time slot. Because my work is so closely based on studying period pieces, I tried to show some examples prior to my demonstrations. This blog post will flesh out some of what I was talking about.
Al Breed came to one of my sessions, and asked about the insides of the mortises; is there any indication that the joiners bored them first? My reading of the evidence is that these narrow mortises, typically about 5/16″, are just chopped. No need to bore them first. These shots (scanned from slides, thus not as sharp as they might be) show the inside of the top front rail of a chest from the Smithsonian. The chest was made c. 1640-1670. Oak. The joint is broken open near where the till parts fit. One of the nice things about oak is how well it splits, but that’s a drawback too.
Here’s a detail of that joint, showing the chopped bottom of the mortise, in the first photo you can also see the angle of the mortise’s end grain cuts, and the trimming of the tenon’s edges.
This chest has a joined front fixed to board sides and back. So a blending of a board-chest and a joined chest. Two pieces built this way survive from this shop.
To me it’s not a surprise that this joint blew apart, the surprising part is that more didn’t. I have written before about how much wood is cut away right were all these parts converge – the mortises for the top rails, the grooves for panels on front & side, the notches for the till side and till bottom, and the mortise bored for the till lid. It’s like a game of connect-the-dots.
here is part of that earlier post:
First, the two mortises, for the front and side upper rails. These are 5/16″ wide by about 3 3/4″ high. The one for the front rail is about 1 1/2″ deep, the other about 1 1/4″ deep.
Each has two 1/4″ holes bored in them, those for the front rail go all the way through the stile.
There is a groove running along each edge, into these mortises, for the beveled panels.
Additionally there is a notch cut across the inner face of the stile for the till bottom. this notch is about 3/8″ wide and about the same depth. It is positioned so that the till bottom is flush with the bottom edge of the upper rails.
What is missing from this photo is one more assault on this piece of wood – the hole bored into the stile for the hinged end of the till lid. This hole is usually about 3/8″ in diameter and about 1/2″ deep, and right near what will be the top end of the stile, after the extra wood is trimmed off the top. It will be about 3/8″ away from the mortise for the side rail.
Another thing we discussed (I think this was a breakfast discussion…) was the backs of pieces. Chris Becksvoort was telling us about Shaker work, Al Breed about Newport 18th-century work – I chimed in with a group of chests and cupboards from Plymouth Colony from the 2nd half of the 17th century. Here’s the surviving section of a chest with four drawers; in “as found” condition.
Look inside, the inner face of the rear section is a bit firewood-like. (the strap hinges are replacements) Narrow oak panels, with muntins that have large torn-out sections from riving them:
And a knot in one, and panels with riven texture – not planed smooth.
Sometimes the insides have fully-formed moldings on the framing parts. These get covered up as soon as the chest is filled with textiles. Some Boston joiners did the same thing.
All the chests and cupboards from this large body of work use employ chamfers on the framing parts on the side elevations; usually stopped chamfers. You see it below on the lower edge of the horizontal rail:
But they did it too on the rear elevation. Sometimes smooth transitions, sometimes stopped chamfers. This is the part of the cupboard or chest that gets shoved against the wall! Hard to understand the outside being so neat when sometimes the inside is just this side of firewood.
