Re: [MedievalSawdust] Geometry of Moulding Planes
- The shoulder cutback has nothing to do with the arc of the blade. It was generally cut at that angle to allow the user to get as full a round as they could in complex moldings.William Farissemail: wfariss@..."Never look back unless you want to go that way"

Subject: [MedievalSawdust] Geometry of Moulding Planes
So I've collected a couple moulding planes, mostly hollows and rounds and I'm noticing that the shoulder to the cheek to the left of the blade, which everyone says should be 30° off of vertical (because each plane does a 60° pass per arc so that the width of the blade is 1/6 of the full diameter, etc.) is typically nothing like 30°. Have I just chosen poorly when picking out my antique planes, or the whole 30° cheek thing one of those nice in theory but in practice.... kind of things.Avery
