61.75 ntn. 57 lb at 28. 10 gpi arrow at 153 through chrony. This was the first bow that i made. I realize it not the greatest but im kinda proud of her. What do you gents think!!

There

Do you mean 10 grains per pound? The bow looks nice. Too much bend in too short of an area but otherwise nice job. Try to distribute the bend over a longer area of the limb to avoid set.
-
Yes my bad badger

I like the look of your design congrats ! The next will be faster !

Absolutely! You got an even tiller, despite how most all of the bend is right out of the fades in the handle area. Spread that bend over more of the limb and you gonna have a faster shooting bow. 153 fps from a 57 lb bow and a 10 grain per pound of draw weight is ok, certainly good enough to take game with....but I seriously think you have even better work coming out of your shop in the near future! Looking forward to more of your posts!

Outstanding execution. But the low speed has me wondering why, because id say that bow should be faster. It even holds reflex, and doeant seem to take an undue amount of set, even though i agree, to much inner limb bend. Can we see a pic of the back of the bow? I want to see what its front profile looks like.
Btw, you bend way to much out the fade on that right limb. Heat treat that bend on the right limb to stiffen it, then maybe a few scrapes off the left limb to even the tiller out for ballance, and it should be fine.

Not real reflex though. Tips still in front of the handle gets too much credit.
-
Why? I dont understand the difference?
-
Because the working limb is tired. Better to project the curve of the limb out to an imaginary point in the air below the tips and use that as a true reference to limb condition.
The bow shoots about like a bow with 2-3 inches of set and that's about where the tips would lie.

Here you go sleek

PatM: " Not real reflex though. Tips still in front of the handle gets too much credit."
I agree. I wouldn't say it isn't REAL reflex exactly, but by itself, it only helps a little, and can be detrimental. Fresh and healthy working limbs, and good mass distribution are steps one and two.
Yellowstave: I think you did PHENOMENAL for a very first bow. That's a challenging side profile to start with.
You've gotten a few tips for the future, and I'll add a little. Your limb is overworked in the first 1/3 of its length. With that design, which doesn't taper much side to side, the first 2/3 of the limb should be sharing more of the load. Your outer 1/3 of each limb is barely bending at all, which means it could be much narrower to save weight at the tips.
-
That last paragraph is exactly why i wanted to see the front profile. You nailed it springbuck. Beautiful bow btw. But, go and narrow the crap out of those outter limbs, start in the middle or just after it, and you will pick up lots of speed. You could be in the 160s.

Makes sense. Thanks

Awesome. Thanks for the words guys

Wow, I wish my first bow looked that good! Keep building and posting and you'll be amazed how quickly you improve your craft. ;)
-
That is a pretty good bow for being the first.It is working way too much on the inner limbs like said though.Their worn out.My first shot about the same comparison speed.I'm sure you'll know what to do better next time by the looks of your first bow.Have fun.Post pics and stay in the mix.

It looks to me like your handle could also be smaller. This would allow for more limb to spread out the bend. You don't need much handle. When I first started making bows, I did the same thing. I made these really long handles until it occurred to me suddenly that as that part of the limb wasn't bending, it was just subtracting from my bow. I was following the general lengths you'd expect for a self bow (around 65'' for me), but I wasn't calculating the length of my non-bending handle into that calculation. So, there wasn't enough bendable limb going on. My limbs were overworking. I kept wondering why my bows were taking too much set when I was so careful during tillering. This was why.
-
First bow? I wouldn't change anything. But there are some great points for the NEXT bow. Lol I have shot that bow and it's pretty darn smooth. I say it's a victory brother
-
Three yr old bow with hundreds of arras thru it. Minimal set very smooth and PLENTY FAST
-
Great work on your 1st bow. That's a tough design and impressive that you pulled it off on your 1st one.
I'm assuming it's osage?? or did I miss the material description?

+1. More handle equals less working limb. I would also add that I don't necessarily even like the look of long handles. I have big hands yet I don't like grips longer than 4", and personally don't see the need for one's longer than that unless you're doing a serious arrow self, yet I don't particularly like those either. But if you do like arrow shelves and long handles, all power to you, as that's your preference and should be allowed to build the bows you like. Just factor in how much longer your working limb will have to be if you do so.
I think you did a great job regardless of whether it's your first bow or not. There could be more of the limb working, but that's an error I make all the time too. It's bending even and is sleek looking, and no doubt a good shooter.

Bayou ben. Yes its osage. Thats all ive succesfully worked thus far in my bowyers journey. I tried a black locust with no luck and a mulberry that failed. Ive made a few others that are faster with better tiller but ive given them away and lost the pics on my other phone that got shattered by my skidsteer...oops. Anyhoo thanks to all for the comments.
-
I think you got some good suggestions for your next one. I agree it's a very nice first bow. Look forward to seeing more. To bad about your phone. Man I'd really hate to lose mine I've got so much stuff on it.

" I tried a black locust with no luck and a mulberry that failed."
That's so funny, because those are literally my two favorite woods. But, that's probably because all my osage ever was bought or acquired second hand. Keep it up!
