Woody, et. al.
I have done a considerable amount of reading the past few days on crossbows, both here and on the Excalibur forum. I took one of the tips that was on there, and added it to my Revolution - the tip about stopping the bowstring from "overtravelling" after the bolt is released from the string to help cut down on the noise. It works! It took me 3 hours of design and milling time, but it was worth it.
I also saw that there are some nice wood stocks made for the Excaliburs, and thought that I could cut down on the noise of mine if I could deaden the stock somehow like a solid wood stock does. I called Barnett and was told that the stock is filled with Nitrogen for strength. I hung up and said "Bu..sh.." If that's true, then why can I pressurize the stock and hear air escaping???
So, I drilled a few 3/16" holes in a couple of strategic places that aren't stressed when the bow is cocked, and filled the stock with expandable foam. After letting it ooze out of the stock overnite, I trimmed off the excess, and tried it. I believe that the noise is cut in half, easily, and I still don't have any silencers on the string.
So, just a word of THANKS for the tips here and over there.
By the way, with Beman ThunderBolts, 2" Blazers and 100 gr. tips, the bolts weigh 420 grains. I used some broadhead backers (aluminum spacers that weigh a bit under 1 grain each) to get the bolts within 1 grain of each other. They are leaving the bow @ 325-328 fps and are very consistent.
Now if I could just find a varizone scope and a quiver cheap............
Thanks again,
