We talked about the general layout of profiles and purpose. Philip seemed to have everything down about which I have written. He wanted a cove and ovolo on the edge of some walnut for the base molding of a piece on which he is working.
After drawing the profile on a piece of paper Philip drew 3 of the 4 rabbets correctly. He only missed the small fillet on the outer edge, which could be added at the end once realized.
Getting the layout for this molding is probably 45% of the process. The next 45% is transferring that layout onto wood and executing the rabbets accurately.
So, where was Philip having issues?
The iron's edge on a rabbet plane MUST project slightly from the body's side.
Here is a rabbet I just cut with the iron projecting about 1/128" from the plane's body.
Here is a rabbet I just cut with the plane's iron flush to the plane's body.
Do you see the difference?
Any time a plane is intended to cut a vertical facet--rabbet planes, moving fillesters, side beads, ogees with fillets, snipes bills, dovetail planes (I've never actually used a good one), etc.-- the iron must project slightly from that vertical facet on the plane's sole. A fence will not fix this. The iron should project along these vertical facets but neither cut nor scrape.
