Can you shrink them down, that one you posted looks close to 185kb which is about 15 kb shy of maximum per post. Unless you want to post however many photos you have in a new post, which is extraneous I would just resize them or you should be able to post them to someplace like flickr or photobucket and link them. That's a nice looking first bow by the way.

Thanks Michael I figured it out.
Heres more pictures.

You can see by the pictures your limbs don't bend at all in the fades, run dead straight for 8" or so, hing badly, and run pretty straight to the tips. You made a beautiful bow but the tillering is off a bit. You can partially correct the hinges in your limbs but you will loose plenty of poundage in the process.
If you make one of these and use it on your next bow you will have limbs that bend correctly with no hinges.

nice job on your first bow.
and good job on the finish.
like that snake skin back.
My first 5 didnt even shoot and looked much worse. :D
One other suggestion. you could narrow up your tips a bit also. might make the bow faster and less hand shock.
Or just shoot it and have fun. nothing like the feeling of finishing your first bow that shoots.
good job.
-
Nothing like your first shooter,like Eric said it could use a little fine tunning on the tiller but other than that the finish work and skins look great.By the way did you leave the sap wood on that Osage or back it with something ? Congrats. :)

This site is for people who post home-made bows and learn from others. Congrats on your first one. Bookmarked, too, for BOM fun.
-
Good job on your new bow.. and good suggestions from the gang. I wish i knew how or was confident enough to try a splice.
good Job
Mike

Nice job on your first bow! When you make your next one feel free to post some pics early in the tillering and folks here can give you some suggestions...lot of experienced bow makers here. ;)
-
I am glad I made my first bow before the digital age so no one got a look at it. Your first is 10 times better than mine even with the tillering issues.

Thanks guys!
I knew there was a bad hinge in the lower limb, and didnt know how to fix it. should it really bend in the fades? I was kinda going for the D bow look and I thought they were to be Straight for a ways.?. Yeah I left the sapwood on the bow instead of backing it. It seems to be ok with it on there. I didnt know at the time I started that you could take the sapwod off. But for my first bow I am pretty happy with the outcome.
I have another stave on order, and will post pictures so I can get a little Help on the tiller of the next ones.
Thanks again guys for all the info I really Appreciate it.

If you come acroos a hinge, remember the old addage... remove wood where the limb doesn't bend enough, and leave alone areas that bend too much. In other words, don't take off anymore wood in the area that is hinging, and remove more wood from the flat areas that don't bend. Try and end up with a more even bend, where the entire limb is doing work. This will add to the bow's life, and greatly reduce set. Try and end up with a tiller something like this:

Good job with the snake skins.
Eric, I now own a tillering gizmo
-
Do you guys think I can fix this bow? Where would I start taking wood off first?
-
i would start off by getting more bend in the fades and a little smaler tips on it. like they said you can allways take wood off but its hard to put back on. you will loose some poundage . but it may save you from a broke bow. and on osage you allways need to take all the sap wood off and work the back down to one growth ring it will keep it more gooder. thats my opinion there is alot of good people on here so dont think people is gone make fun of ya. so ask away every ? you got you will get alot of help. we all built a first bow.

Congratulations on your bow. It's a very good first effort. The bending can start at the end of the fades. Let it start there and increase as you out towards the tips. You should see that in your ow all the bending is taking place at one spot. Mark a big x in pencil there so you don't remove wood from those spots. Make a pencil line at the end of the fades where you want the bending to start. With our scraper remove wood until the bending starts there but first lower your brace height to about 2 inches from the belly. BTW never pull a bow further than it takes to expose a problem so we are talking really short draws here of 10-15 in. Next start scraping beyond that hinged spot to get a nice even bend. Always exercise the wood at very short pulls for the wood removal to register. There's much more on my site. Jawge

A lot of good advice given to you all ready. Remember that the stress is looking for a weak spot in the limbs. If it finds that weak spot it can cause a hinge. The idea is to blend that stress of a drawn bow throughout the limbs and to balance the limbs with each other. Depending on how you lay the bow out can come into play with the limb balance. I usually lay the handle out where the center of the handle is at the center of the bows length. When layed out this way, I try and have the top limb slightly weaker then the bottom. I judge this easiest at brace where the top limb measures out 1/8" to 1/4" more from the string perpendicular to the belly.
One way to get more working limb is to cut down on your handle and fade lengths. I lay mine out with a 4" handle and 1-1/2" fades...basically 7" on nonbending area in the handle/fades. I usually leave my tips slightly thick for about 4" or so as well.
These are just some of my practices...lots of correct ways to go about making a bow. You can learn a lot from asking questions here, I know I have. ;)

Agreed. Lots of good advice so far. I'd leave this one alone and start the next one. Nice splice job, btw.
