How to Cut Curved Moulding

Curved parts can be tricky to cut precisely. The basic principle here can be applied to any size moulding, and can also be done on the table saw with a sled and larger discs. The curved pieces are turned on the lathe in full circles. You'll get two pieces of corner moulding per full circle. Allow for several extra pieces, as you'll need them for set up and errors.

Quartered corners, the finished product.

Make a full-sized drawing.

Make a sled for the bandsaw, and position your cut-out pattern as shown.

It doesn't need to be precise. The setup will allow for adjustment.

Use router bearings or other discs, and allow room for adjustment when screwing them down.

Make a trial cut of your first piece.

Test your cut against your pattern.

Make necessary adjustments to the bearing position.

Make your second cut, and check the length.

Install the corner pieces as you install the straight sections, and trim them to fit.
