I am making a tall case clock (a reproduction of a simon willard “roxbury” clock) and I am about to start on the molding for the hood. The molding is a half circle (about 8 1/2″ radius) which is a combination of a large cove and a smaller bead. I have no problem on the straight part of the molding (than runs along the side) but I am stumped as to how to make the cove on the half circle. Any suggestions? Thanks

Thre are two ways you can make the cove. One is a scratch stock, a sketch of a suitable example I have attached. You would have to bring the inside of the leg to a radius to follow the radius of you molding but the idea is simple. This is simply a scraper ground the form you desire and held in a jig to guide it.
The second method is to glue with a paper joint sections band sawn to the rough size of your molding to a circle of plywood mounted on a faceplate. You now scrape the form with turning scrapers. You will need to make the molding in 8 sections to make the idea work. I have attached a couple of photos of a circular window molding I did this way. I cover this in my Turning For Furniture book published by Taunton Press.
