boo backed ipe warbow dimensions?

<< < (2/2)

Derek,
I was thinking about your post today. If any mild relfex is to be glued in I would advise an inch and an eighth rather than an inch and a quarter. That should be plenty for 90lbs, just take care to avoid hinges toward the tips area where width and depth tapers converge.

P.W. Smith:
I was thinking of just a straight stave boo backed ipe with no reflex glued in...for me its much easier to tiller without reflex than with it. anyway, I finally got the ipe board cut out and have three bow blanks from it...I also am prepping some thick, strong-and yet unidentified pieces of boo that I picked up at a gardening store...does anyone have a good method for tillering these bows (short boo backed ipe style)

Rich Saffold:
I'd want my final dimensions for the bow you describe to be 72-73" 1 1/8th" max 1" for the heavier ipe. Bamboo 1/8th-3/16th's thick, and I would glue it up with an inch of reflex. I know straight is "easier" but the bow limbs get a little more zip for their mass, and a little reflex isn't much over the length of that bow and not that hard to tiller. If you are comfortable drawing 90# bows than these bows really aren't that hard to floor tiller past stringing height. I just lay a little weight into the grip and focus on what I am seeing.

Get a bunch of good scrapers too..

Badger:
       I would go along with Rich and JD on that.  While back I made one 110# at 28 that was 1 1/8 wide and 73' long. I wanted to see how far it would pull before it failed and I got it out to 34" and lifted a few splinters on my boo. Strong stuff. Steve
