I think that's the biggest problem with the Byrd heads....they are nowhere near chip limiting. I think the new Felder heads are but I'm not sure. The Hermance heads and some of the other ones look better, but I'm not sure if they would satisfy the requirements to be MAN rated. Like you say, no big deal on a planer, but on a jointer....
It has been a long time since I looked at a Byrd head, but my memory tells me that the “perched” squares were not machined out of the solid head, but rather welded on.
I might be wrong, but someone here can surely verify this.
I've been a user and fan of Byrd heads for a long time. I put one in my 8" PM60 jointer, 12" PM100 planer, and now in an SCMI 12" Jointer. Having said that if doing another upgrade it would be a Hermance.
Does Felder offer their proprietary head for sale for other machines? Is it MAN rated? If so that would probably be the best head. What is the radius on the tips?
It would be interesting to see the performance difference in wild grain where the Byrd has a greater shear angle.
I ran across a site where the guy tested the Byrd and Chevron and kept the Byrd. sorry, can't remember where it was.
I have a Hammer a3-31 with a Byrd head and I get almost no chips or dust that my dust collector doesn't get.
Would you mind asking your Felder colleagues if they plan on offering the head as an after-market/retrofit option for non-Felder machines? It would be nice to know if it can be on the list of heads to consider. Does Felder make the head themselves or is it farmed out? Could you share the shear angle?
Thanks Joe,
