Oh Boy am I put on the spot.
I have not heard from other customers about the problem.
The new spiral is now my best selling spiral. Some who have used how ever a lot of spirals still like the regular spiral still.
Th NS is a lot easier to control, cut a little slower.
You need good tension, and good speed. With not enough speed you have a tendency to push too hard into the blade, you loose control over the blade. The
# 3 should be about the best number for cutting close to 1/2" thickness.
About the Olson blades. Olsen blades are made by the Hounstetter company in Germany. Olson never made their own blades. They are sold a lot in different stores mostly under the store name, like Delta, Dewalt. I don't know if I was of much help but i tried anyway.
Here is how the new spirals are made.
The regular spirals are made from regular flat blades. Before they are
hardened, they go through a machine to twist them. That machine looks like a
Roto router. Seen it and was very impressed.
The regular spiral are somewhat aggressive and have a mind of their own.
Hard to control, they like to go to the soft spots in the wood. However I
have to say, that the people who have used them for a long time and know how
to work with them, will stay with the regular spirals because they cut
faster.
The New Spirals are also made from regular flat blades. It is a compete new
design and this blade would not be good to use as a regular flat blade. This
new blade has teeth on the front as well on the back( this is patent).
Because of this, the teeth are smaller and less aggressive and much easier
to control. The user is the boss not the blade, like as with the regular
spirals.
I feel that the company came out with a new spiral what made it so much
easier to use by people who did not like the other spirals, like myself.
I hope I explained it OK
