Da Vinci arch woodshed

From A Corujeira. A reciprocal barrel vault in ripped cryptomeria on a Euro pallet deck. Change any number and the model, templates and cut list update. Lengths are in millimetres.

Shape Pallets in a row Span Between the centres of the two foot cross bars Depth Pallet depth is 1200 Sections Base height Upright pallets or stub walls under the feet. Adds height without changing the arch Runner layout

Timber Strip depth Finished rip width, set on edge Strip thickness Cross bars Notch depth Under each runner end, catching the bar edge. 0 means none Notch width

Layout Standing height Used to measure how much of the floor you can stand in Runners per lane group 3 lane groups, so 2 gives 6 lanes across the depth. When grouped, this is the number of clusters Gap within a cluster Between the three runners of a cluster. 0 means touching, so they can be pinned together Cluster inset from edge From the front or back face of the deck to the outer runner Runner overhang Past each end crossing Cross bar overhang

Build notes

Cut one runner and three cross bars first. Dry fit a course on the ground and check the bend before cutting the rest.
Notch depth changes the curve, so keep it consistent. Screw each centre crossing so runners cannot slide sideways along the bars.
Fix a sole plate along each foot and bolt it through to the pallets. Join the pallets to each other so the deck holds the outward thrust.
The vault racks easily along its depth. Brace the back face with diagonal slats.
Strap the vault down against wind uplift.
Fix battens over the outer high points before roofing.
