That’s really interesting. Strange, simple design, I’d love to see it in action. Does it produce a decent chamfer? The iron is tremendously skewed and at an incredibly high pitch. how is the depth of the chamfer controlled? Etc. Does it produce chamfers or spills as suggested?
A while back I fixed up a Mathieson (I think) chamfer plane. It works ok but there must be a technique to using these things. It is difficult to place them on the arris, they kind of rattle about.
Not sure if I have a decent pic of it, I had to make a new wedge. And iron I think.
