IBC/Rob Cosman Revival Plane Blade Set (2-5/8 inches)
One of the best ways to improve the performance of an older Stanley or Record plane is to replace its original blade set with a thicker, premium blade set.
Not satisfied with the way replacement blade sets fit and worked in older planes, I teamed up with IBC and designed a blade set specifically designed to work in older planes
The problem is that the older plane's adjustment system was not designed for modern, thicker, premium blades. To solve this, we added special "tabs" to our premium blade set that enables it to engage the older plane's adjustment system in the same manner as the original blade set. This allows the blade set to adjust like an original Stanley but perform like the modern, premium blade that it is.
2-5/8 inch wide Blade & Chip Breaker Set. Fits older Stanley and Record No. 8 planes.
At .140 inches thick, this blade set is almost twice as thick as that found in older Stanley and Record planes.
It may be necessary to file open your plane's mouth to accommodate the thicker blade.
Blade is high vanadium A-2 steel, 0.140” thick, 60-62HRc and cryogenically treated to optimize the cutting edge’s wear resistance properties.
Chipbreakers are unique – high carbon 0-1 steel, 0.125” thick and hardened to 30-32HRc for added stiffness.
Bevels are mated to achieve a flatness tolerance of +/-0.001” along the entire width of the cutting edge.
The quality of the blade is very good but the chip breaker is produced such that you can’t have it positioned close to the edge of the blade and still get it to protrude out the bottom enough to work. I had to slide the chip breaker back about 3/8” in order to get it to work. It does work this way, and it is better than the original blade, but I'd rather I could set it up like the others I own. Maybe after I’ve used it for awhile I won’t notice it anymore but right now when I take the blade out to sharpen it it’s pretty glaring. I need to figure out a good way to mark where the chip breaker needs to be positioned to work so I don’t have to keep measuring or guessing.
The blade worked great right out of the package but, the chip breaker seems a little short. My plane is from around 1902 to 1910 a corrugated sole #8. in order to get the blade to cut I needed to set the chip breaker about 1/4 of an inch back from the cutting edge. It does not seem to effect the performance. I did need to file the mouth open to get the blade to perform. When I flatten the bench I am building that will be a real test of the blade.
