Thanks Roy! I haven't picked a top limb yet, but it may very well be the left, because its got the thicker bamboo, and the ipe is approaching the same thickness as the boo. now that positive tiller is measured from the string to limbs right past the fades while braced... correct?

Correct

7" brace, 50# @ 23". damn near perfect tiller says the gizmo, takes very fine adjustments or i get no mark or a line down the whole limb. 5" to go!

Well done eric.You learn fast--Joe

thanks guys. any pointers for this part of the game? i can definitely see how one could get excited and rush the last bit of tillering. I promise im not going to do that! the curve on the limbs is consistent all the way down, except 4 or 5 inches from the fades and the last 4 or 5 inches to the tips is a little stiffer. is that what i want, or should i make more bend near the fades and tips... shoot for consistent curve from fade to tip?

is it a problem that my ipe is the same thickness as the bamboo, and will likely be a whisker thinner than the bamboo by the time she is done? next time i do a bamboo backed bow i am definitely making it thinner.

might be more aptly called a IBB (ipe bellied bamboo)

I would use a scraper and remove wood equally from each limb to attain your 50 pounds at your draw length. But I would leave the bow at 54 pounds because it will lose a few pounds in the final sanding and a pound or two shooting it a few hundred times.

Roy, Im actually hoping to end up at 47#, thought I said that, but maybe I didnt

Roy from Pa · « **Reply #270 on:** March 16, 2013, 08:57:00 PM »

Ah make up your darn mind, son:) Ok then make her 50 if it makes ya happy:)

Echatham · « **Reply #271 on:** March 16, 2013, 09:07:00 PM »

My mind has been made up ya old fart! i said i was shooting for 50 cause i know its going to drop a few lbs and end up at 47 where i really want it!

Roy from Pa · « **Reply #272 on:** March 16, 2013, 09:14:00 PM »

Figures a sailor kin only pull 47 pounds...

Echatham · « **Reply #273 on:** March 16, 2013, 10:31:00 PM »

haha well im pulling 53# right now, but i can shoot a little lighter much better.

Roy from Pa · « **Reply #274 on:** March 17, 2013, 07:21:00 AM »

47 is a girls bow weight:)

Echatham · « **Reply #275 on:** March 17, 2013, 07:25:00 AM »

haha its a deer slaying bow weight is what it is!

Echatham · « **Reply #276 on:** March 17, 2013, 07:27:00 AM »

but ya know, I have been thinkin... 50 is good too. and it requires less scraping to get there (ya im that lazy) so i tell you what, if i get to 53# and im happy with the tiller, I will leave her right there.

Echatham · « **Reply #277 on:** March 18, 2013, 11:15:00 AM »

takin a couple days off from the build to catch up on my honey do list, in case anyone was wondering. don't worry, I'll get back on it as soon as the yard and garage are ready for spring!

Echatham · « **Reply #278 on:** March 19, 2013, 05:48:00 PM »

53# @ 28"

3/16 positive tiller, with the left limb being stiffer. don't bother counting holes in the peg board, the rest at the top of the tiller tree isn't exactly level.

so.... what do i do now?!
