Oella saw and tool combination corrugated knives

[Mike Kees]

Has anyone used these ? I was browsing through their site and found this idea, Corrugated knives made with holes to fit Williams and hussey style molders so they can serve double duty in a corrugated head on a shaper or a W and H moulder. I have the shaper and corrugated heads as well a a G.I. molder . I have been following the other thread on corrugated heads/knives and was wondering if the grinding angle would be the same for both machines ? Thoughts .

[Joe Calhoon]

Thanks for pointing that out Mike. I have considered buying the head to run W&H profiles on the shaper. This would make more sense. Some of the profiles the straights are easier to run on the shaper or moulder and curves on the W&H.
No idea about hook angle compatibility.

Charles G. G. Schmidt (https://cggschmidt.net/cggwp/categories.php?cat=76) also sell corrugated back knives for the W&H/shaper if you are shopping around.

Peter have you bought any ? I think I will buy my next custom profile this way,seems like there would be no disadvantages to it. I am doing some casing for a 90 year old house right now for a friend that I work with occasionally,we just had a set of custom knives made to match the original profile. If i had seen these I would have tried them out.

I run the combi knives interchangeably all the time. I have not compared the profiles from one to the other side x side, and would expect some compression of profile if hook angles were different, but they cut well in either instance.

The hussey is a 23 degree hook. You need to specify the primary use and live with a bit of mismatch on the profile.

Wkw and Titan (among others) make corrugated w&h steel. Any shop can grind it.

I don't have a shaper so haven't bought any. I bought a book from them decades ago about grinding but have always kept them in mind. I may be wrong but I believe corrugated washers will be needed to put under the heads of the bolts unless they counterbore them. Worth asking either source if you are buying a set.

Jared/Peter (2) thanks for the information.

[Joe Calhoon]

+ 2 on the thanks. Wish I had known about these 3 months ago!

What grade of steel is the longest lasting ?I guess what I am saying is what grades do you guys specify when ordering knives ?

M2 is standard. Avoid "like m2" or "equal to m2"

There are others d2, m3, for applications.. but m2 is the vast majority.

[Mel Fulks]

Agree with Jared. Some vendors really push the "same hardness" as M2 thing. If you see striations on wood left by knives,
It probably is not M2. M2 ,I'm told , was a war time substitute for T-1. A few years back they started making T1 again.
But real M2 is fine.
