Limb thickness, and tillering questions

[Tortoise]

Hi
A couple things:

1. I'm progressing ever so slowly on my first osage/hickory longbow. I'm trying to go for around #50-55. I don't know what the proper limb thickness (not width) is for this weight on a pyramid bow. Could someone please help me sort this out? The current stats of the bow are:

• 1/2" wide tips
• 72" long overall
• 31" at the end of the fades
• Back & belly are 2 1/2" wide at the end of the fades
• Backing is 1/8" thick hickory
• The limbs are currently 3/4" thick

2. Also, should I tiller the bow with the limbs the way they are, or tiller it after I thin them? Thanks  I just want to do it right the first time instead of dealing with the stress of an issue.

Are you only going to tiller from the sides? Jawge

what is your front profile/ measurement's at fades and tips, will make a differance on finished thickness, Bub

Sorry I forgot to put that in there  The entire length is 72", the limbs are 31" at the end of each fade.

how wide across the back of the bow is it, maybe and inch and 3/4 strait taper to half inch tip's?

The back (and belly) is 2 1/2" wide across. The limbs are 3/4" thick at the moment with a 1/8" hickory backing strip. The tips are 1/2" wide. I'll add all this info to the original post as well.

most of my pyramid's are 66" ttt, one and three/quarters to two inches wide at the fades and i start with a limb thickness of 1/2" even thickness from fade to tip, 2 1/2" is really wide for osage and you might want to reduce the fade width to 1 3/4", at the present width it's gonna get real thin and you'll probablly end up side tillering anyhow, Bub

But 1/2" thick is good for what I have currently, right? Also could you tell me what side tillering is, I'm not sure

[bubby]

1/2" should be good to start, side tillering is when the scraping to drop #'s is done buy scraping from the side's of the bow, but i rarely do this myself, Bub

Okay thank you so much, I'm out working on it right now
