Question about Tillering a R/D Bow AND Other Questions about Weight

<< < (2/3) > >>

Pat B:
...also practice at very close range...3' or so on out to your max. Wouldn't it be a shame it you could punch the ace out of the middle of a playing card at 30 yards but can't get a good shot at 3' or 10 '. Does your arrow fly well at 3'? There is a very good chance that is where your shot can be.    Pat

 What Pat said is important in Imo. I hunted rockies out in new mex on the Apache reservation some years ago. What REALLY surprised me was how close your shot can be ! Can be measured in feet not yards in alot of cases. This is where most of dont practice because we think its a given.......surprise, surprise ! Also as Pat said its your arrow more so than the bow or draw weight in most cases. .......bob

Justin Snyder:
You ain't just kidding either Pat.  Of all the animals I have shot with a bow, one was outside of 10 yards.  I have not shot an elk yet. I have been close enough that had I released the arrow, It would have hit the elk before completely clearing the bow.  :o If you really want to maximize penetration, 2 blade broadheads or rock points will usually slip between the ribs. Then all the energy you would have wasted breaking the rib cage is used in penetration. Tapered shafts also reduce the friction on the shaft. Justin

Thanks for all the replies! This is plenty to chew on. I've killed two elk, a bull and a cow. The cow was shot with a 55 pound recurve at 18 yards and the bull at 12 yards. In either case I'm sure a 56 pound selfbow would have done the job.

I appreciate the reminder about the arrow and scary sharp broadhead. I don't want to overbow my self and screw up my shoulder.

I'll post more tomorrow. Right now I'm on a carp cleanup mission at the local river. Here's a Bass I arrowed with one of my homemade bows.

Okay, I just reread the article by Jim Boswell in the April/May 2007 issue of Primitive Archer. Although it's titled, "A Reflex Deflex Glue Up" it has some good information about tillering. The article is based on a bamboo backed hickory bow. Boswell provides the following measurements: 1 1/2" wide 1" past the fadeout (I'm assuming on the way to the tips), narrowing down to 1" at the tips. THEN take the last three inches and narrow to 5/8 tips. He indicates this method will reduce handshock and improve performance.

If these are the suggested measurements for Bamboo/Hickory, what would you recommend for Bamboo/Ipe? I've thinned the Bamboo down to just under 1/8 inch thick.

The blank was glued up yesterday and will be ready to cut to profile in a few days. I used Bowgrip 100 and let the glue cure in the sun. The temperature in my space blanket hot box was around 110 degrees for four hours.

Thanks again for all the help.
