I didn’t have much time for woodworking this week. However, I did take a few minutes to get the wedge for my first moulding plane cut out and to the right thickness for the wedge mortise.
Last week, I mentioned that I would take some photos of the plane makers floats I used and where they are used in the process of making a wooden side-escapement plane such as a moulding plane.
First up is a crank-neck float. This isn’t a dedicated plane making float, but it is a handy tool. The toothed portion of the blade is around 3 inches long, and reasonably flat. This makes it a great tool for leveling and cleaning up the grip of the plane. I also used it cut the rounded profile of the plane. I had to use a straight-edge to make sure it had a straight profile along the length of the plane, but it worked out well.
Once the mortise roughed in by boring and the removing the waste with a chisel, the float work in the mortise begins with the side float. As can be seen from the photo above, the angle of the float is just a little smaller than the angle of the escapement. This float is used to remove material from the sides of the wedge mortise and to refine the fit of the wedge. Floats can leave a very clean finished surface, so they are also used to refine the mortise once it is close to being the right size. Both sides of the mortise get cleaned up with the side float. At the moment, I’ve only made a push style side float (it cuts on the push stroke only) and I’m considering making a pull style side float as well. The pull floats are good for removing material at the mouth of the plane because the force required to use the float moves from the narrowest part of the mortise at the mouth toward the larger grip end of the mortise. This keeps the mouth from being damaged.
Next, the bed (back wall, where the iron rests) and breast (the front wall of the mortise where the wedge is puts pressure to hold the iron in place) of the plane are refined with the edge float. Again, the angle of this float is slightly less than the wedge mortise angle. This float is used to make the bed and breast straight so that the wedge and iron will make full connection, which will affect how securely the wedge holds the iron in place.
The final floats that are used in making moulding planes are cheek floats. I use both push and pull style cheek floats. These floats are used to hollow out the sides of the mortise slightly. This helps to make the wedge fit a little better.
That pretty much covers the use of these floats in making a moulding plane. I plan to order the plane iron blanks for this plane and it’s mating hollow (concave) plane from Lie-Nielsen Toolworks. Once I get these irons, I’ll write some posts about profiling the iron for this plane and then I’ll make the hollow plane and get some photos of the process so that I can write a post about it.
Until next time. . .
