So I felt close until I got back to tillering this morning, and I'm a bit confused  ???.



Here's the bow at 12" approximately - I'm still not sure where I should be measuring brace/draw height from. That's pretty tense and I get a little jittery pulling it beyond that. So I can't believe I'm supposed to be pulling it back 18 more inches, to my draw length of 30. What am I missing here?

Del also did a great job explaining tillering to me using a scale. I went out and got a luggage scale from the hardware store this morning. When I pull it back to this 12" nock I'm only at 15 or so pounds. I want to tiller it to 35-40, so do I just need to haul back on the string until the scale says 40, despite the fact the limbs feel like they're under a lot of strain already?

Tiller is looking good just exercise it and slowly stretch it out till you get to 20" or so then i take mine and finish getting to draw by shooting the bow just short draw and slowly work my way to full draw

Well damn. Looks like it's time for me to get my card scraper out and get back to work. I'll post another pic in an hour. 11 hours till the shop closes.

Wait - question. If it's 3 lbs per inch of draw, does that mean I want it to be at 0 lbs until I'm at about 17 inches? And then for the last 13 inches it'll go from 0 to 40? That...doesn't seem right.

Sorry if I'm asking dumb questions this morning.

Bows are mostly linear. If you measure the actual power stroke(from brace to full draw) and divide that into the draw weight that will give you lbs. per inch. In your case if you have a brace height of 6" and your draw length is 30"( I'm 6'1" and have a draw length of 27") you have a power stroke of 24". If you have a 48# bow you will have 2# per inch. So at one inch draw it will have 2#,2"-4# etc

Take scrapes the length of the limb, do ten each limb and exercise the bow exercise it till u hit 40# then you will know how far you need to go to get the draw weight needed

So Del told me to man up and pull it back and that's what I did. One of the scarier experiences of my life but we're still in the game so far. I got 35# when I pulled it back to approximately 24". I think I'll adjust my #40 to #35; I don't feel like stressing the limbs any more than that!


~18 lbs


~22

I'm not sure what happens next. I'm getting #35 lbs at 24 inches. Maybe I should stop now? When I pull it back I can't get the string all the way to my face, but it's close and it feels...pretty good.

The only thing keeping you from drawing any further is fear >:D
Don't worry that will pass

If the right limb is the top limb, then it's a tad stiff... if it's the lower limb it's pretty good.
Yeah, shoot an arrow quick before it explodes >:D
If it goes bang later, then at least it's had a shot!

Thanks everyone for your help. I took it to the range today, and believe it or not she held together! Shot a few dozen arrows. I'm still bracing it pretty low (getting plenty of wrist slap), but I'm not gonna push it till after the big presentation. Feeling pretty good and I owe it all to you guys. MVP award goes to Del for responding to a dozen PM's a day for several days.

I'll post a big breakdown with the whole process next week! Time to catch up on some much needed sleep.
