Appreciate advice on how best to fit quarter-round molding to the bottom of a traditional staircase with a curved base. The base appears to be almost half of a perfect circle and the old molding must be replaced. Is this a stardard part that is available or is there a technique commonly used for curved molding?
Thx...

With a good bit of luck, you may find a stair parts supplier that has a piece of 1/4 round that will match your stairs. If not, you would need to make one to match. You didn't mention the radius of the piece, but I gather that it is the piece that goes around the rounded end of the first step. Assuming that is the case, make a form out of a piece of 3/4" plywood and has the same radius as the step. Next you will need to get a number of thin strips of wood (of the same species as what you are replacing) that are the same height as the old shoe. Put a piece of duct tape around the edge of the form to prevent the piece from sticking to it. Glue up the strips and clamp them around the form leaving plenty of extra length on each end for trimming. Once the glue has set up, use a router with a round-over bit of the appropriate radius to match the profile of the old shoe. You may need to do some sanding to fine tune the piece, but since you are only making one piece, that shouldn't be a problem. This should provide you with a curved piece of shoe that can be cut to fit. Another way to go about this would be to turn a full circle of the shoe on a lathe and then cut out the section that matches the old one.
If you like to keep things simple, hope that you can find one at a stair parts supplier!
