Back to the Mazerolle tréteau, or, welcome to my nightmare. This sawhorse serves as a vehicle for roof carpentry study, and I do need more than one sawhorse, so what the heck! Previous installments are found in the ‘Blog Archive’ to the right of the page.
One thing I’m thinking of doing a little differently from now on with these longer threads is to reference what I am doing in each thread to the project as a whole. I can imagine with lots of parts and some similar regimes of cut-out, it can sometimes be a little confusing for the reader trying to ascertain exactly what I am up to at a given stage.
Today I’m going to show the cut out work on the long side x-braces, or the les croix de Saint André, indicated in red in the following picture:
The Saint André crosses, by the way, would be translated as ‘Saint Andrew’s crosses’ in English, though actually in English they are called ‘saltire’ braces. Funny enough, there’s no getting away from the French language here with the term, as the origin of the word ‘saltire’ is old French saultoir/sautoir, which in turn comes from the Late Latin saltātōrium, meaning ‘stirrup’ and ultimately from Latin saltāre, which means ‘to leap’.
The first order of business was to process these two lap joints, which are mitered half-laps, with the miter unequal on each side of the brace member. So, first I laid out the two miter angles on a stick of red oak, then hand-sawed to the line and planed them true. Here we are part way through that process:
Now it was time for the fiendish part – the angled tapered mortises. I wasn’t expecting it to be such a good time, though it was really just a matter of patience.
The mortises slope two directions and taper, and while my first thought was to run screaming, in the end I decided to fix the stick atop my sawhorse with a couple of pieces of mdf acting as shims to incline the piece, so as to relieve me of having to angle in two awkward directions with the drill:
And I’ll take the other ones up next time, as I’ve reached my self-imposed 15-picture posting limit. Hope to see you next time. Thanks for dropping by. –> Go to post XV
