267349 John Ruth <johnrruth@h...> 2018‑12‑16 Shop-made blades for Stanley #70 or #70-1/3 Router Plane
GG’s

Pursuant to a recent discussion of obtaining blades for the Stanley #70 and
#70-1/2, I offer this picture of two shop-made blades I bought as part of a box
lot at a local flea:

The blade on the left appears to have been ground out of a flat file about the
width of a U.S. penny and perhaps 3/16” thick.  The lower part has been ground
thinner to make a grove about 1/16” thick.

This blade appears to have been made solely by grinding, without any forging.
There may have been some tempering to make the blade less brittle than a file.

The larger blade might be a factory blade, though it has a slightly homemade
appearance.  This one must have been made by forging or welding.

Two points:
1) A router blade could be made from a file by simple grinding.
2) One never knows what’s available at a Flea Market unless you GO!  This box
lot was the dregs of a wooden “suitcase style” carpenter’s box which had been
_dumped on the ground_ by an earlier customer who wanted only the box itself.
