rider,

My thoughts exactly!

A couple of summers ago I was around when a 105# hill style bow was strung up. I stretched and groaned an managed to fire off a couple of big heavy wood arrows. It is cool. dead quiet, zero shock and buried to the fletch. If I could shoot it good, I would. but I can't so I won't. That aint kids stuff tho, be careful. I was lucky Rider and Irish, nothing detached.(I don't think).

When I visited Bill Sweetland I was interested in his equipment, but he had already sold it to the folks in Alaska. His advice to me was to not try to duplicate his process, because it was just too expensive. I took him at his word, although it didn't stop me from experimenting, using a high-temp press at Miss. State University. Got my degree there, and had access to the equipment when they weren't using it for something else.

Bill was a helluva nice guy, and gave me the full tour of his place. Our educations were similar, so we could communicate. We spent several hours discussing arrow shaft production and such.

You might want to look into a product that several companies make.  The one I have seen is made by Dalys and is a wood stabilizer or hardener.  If you put a dozen shafts in a tube and then filled it up with this stuff and let them soak a week then take out and straighten and let dry tyou can add spine and weight to shafts.  You would want to straighten before also.  Purple heart or Ipe would be good bets also.  Get in touch with Bill Bonczar at Alhegany Mountain Arrow Woods for good info and material.  Joseph

I've seen 3/8" ramin shafts that were close to 600 grains bare. with a 300 gr head, they would be close. I've also seen ramin soaked for a week or so in poly, that gained extra weight.

This is some Cool stuff .......
