|Pardon the halo on these, a small part of my prized collection|
I recently had a request over on my Instagram feed for some specific measurements from these planes from a fellow woodworker who is seeking to make his own set of molding planes. In doing so I noticed something very interesting regarding the width of the chamfers that are cut to soften the top corners and make the planes more comfortable to hold.
|#2, #8, #16 pairs|
The #1 set, i.e. 1/16" wide, has a chamfer which is 3/16" (or 6/32") wide. The #2 pair goes to 7/32", and this measurement stays the same all the way through the #11 pair. Starting with the #12 pair, the measurement goes up by approximately 1/32" of an inch for each pair of pairs (even and odd), i.e. #12 and #13 pairs are 8/32" (1/4"), the #14 and #15 pairs are 9/32", the #16 and #17 pairs are 10/32" (5/16"). The #18 pair is 11/32" but I do not have anything larger to know if that same formula would continue into larger, joiner sized planes.
|#2 pair - 7/32"|
|#8 - 7/32"|
|#16 - 10/32"|
In a world where many modern makers use the same sized chamfer for all their molding planes, regardless of size, this is an interesting detail. I found it intriguing that handmade planes exhibited this type of precise formulation.
I'd be very interested to learn if anyone else has a set of planes like this which displays this sort of sizing formula.
