I'd like to make some shelves to fit right into the corner of a room.
But, rather than just having them a triangular shape, I'd like the part that isn't against the walls to be an arc...so the entire shelf is a sort of quarter-cirle shape.
Does anyone have any ideas how I can cut four of five of these to look identical with very smooth edges?
Thanks, Mark.
A router with a radius arm or ellipse cutting jig will give the best results.

For the less well equiped try drawing round a dinner plate to get your curve, then cutting the curve with a jigsaw.
If you are good with a jigsaw then you will get smooth curves. If not, a lot of sanding will be required :-)

Use a jigsaw to cut the curve, then use the first as a template for the others? Then finish the arc edge with a router?
Hi Mark
It depends on what sort of workshop kit you have & whether you want concave or convex curves.
Assuming you've already got the sheet material & want convex Basic hand tools: Draw circle with trammel (pencil, stick & panel pin) to size Divide circle into 4 segments - line through centre then another at 90 degrees (use a sheet of newspaper to get a 90 degree angle if you haven't got a large try-square) Saw (using a panel saw) into 4 along previous lines then saw off the corners Saw (using a coping saw) to get curve Sand smooth
Basic power tools: Mark-out as above Cut circle with power jig saw Cut into 4 Sand smooth with maybe hand-held belt/orbital sander
Decent workshop: Mark-out as above Using circle-cutting jig on bandsaw cut out complete circle Using belt sanding maching smooth edge Using circular-saw along clamped straight-edge cut into 4
Once you've got the 4 quadrant shelves scribe them into the wall.
If you haven't yet got the sheet material get the timber yard to cut the circle on their bandsaw.

Cut one out (jigsaw probably) and smooth the edge.
Then get a router (ideally 1/2") with a nice long bearing-guided bit, ideally a "template profile" or "bottom bearing" bit. Cut for shelves slightly oversize, then use the router to trim them exactly to match. Clamp each one in turn to the master shelf, then use the bearing-guided bit to follow the edge.
Alternatively, make them different sizes. It often looks better.
