I am in the process of making a set of three shoulder planes , those being 3/4”, 1” and 1 1/4” wide.
After doing quite a bit of research I finally decided to base my design on the Spiers shoulder plane.
I used Solidworks to design the plane,
Now the Solidworks file was transfered over to the waterjet and the side plates were cut out of 3/16” cold rolled steel plate.
Next the plates are ground perfectly flat on the surface grinder.
Now I had to design and machine a jig fixture to hold the side plates so that the chamfers cut be milled on the CNC mill
Next time the soles
Thanks for looking
