On inspecting my work dry heating in some bend I noticed I had caused a dent on the back of this osage.
I had used a small padded block to shim underneath for a little more bend and the wood was hot where I put the block so even though the block was soft wood it created this.
It is mid limb. Does not appear to have cut any fibers. I have tried to steam it out without results except for getting a red staining around the limb from the red rag I was using ???
I am considering sinewing but would rather not. I just don't think it is trustworthy as is.
What do you think?
-
Sometimes those end up being disastrous. I usually use cut pieces of leather on the back. Hopefully its not a problem for you good luck
-
If it wont come out doobs, I wouldn't use it. That bugger will pop a splinter, bet on it.
-
Ok, thanks guys.
I won't use it as is but what about sinewed?
-
I have done that a few times but never had a breakage. Guess i have been lucky. Just throw some rawhide on it and carry on. Perhaps use an iron on a wet rag or a heat gun to really put some steam to it. Just know, hot steam dries out wood so it needs to rehydrate.
-
Can you reduce some of the width to remove the dent?
-
Pat, no it is right across the middle.
Kevin, I tried the iron and rag-no luck. So you used yours without backing and it held up?
-
I did but after reading the other guys comments i wonder if i am just lucky. Way i see it, if you toss it now its junk. May as well finish and pull it. If it breaks oh well, if not, keep it. I did however do my best to blend in the dent by burnishing the back with most pressure around the edges. I cant see the sent bery well on my phone but i bet if you fade the dent edges out slowly it wont be a sharp stress riser and it will last longer.
-
I have acciDENTally done this a few times.
Early in the 1990s revival of self bowyery, it was common to "bone" the backs of bows. The entire back was worked over with a smooth round object such as a bone or cylinder of metal to compact the fibers-essentially denting the entire back.
Not mentioned these days, but I have done that to the area around a dent and then just finished up the bow. I've done this a half dozen times and had no ill effects.
Now if the dent has torn the fibers, that's a different story.
-
can you go down to the next ring?
-
can you go down to the next ring?
Yeah can you it still looks pretty thick
-
Generally speaking, if the dent is not square edge(broken fibers) you can burnish it and be fine, but not always. I wouldn't trust it as a trade bow or put it in someone else's hands, but I'd build it for myself and see what happens. If you have enough thickness, then doing what Clint said would be the best solution. It's hard to tell by the picture, but it looks like that piece might have a little curl to it. It could just be tool marks though. Josh
-
I took some 1/4" pine and cut it into a bunch of small pieces. I glued leather onto them and rounded the edges of the leather off. That's what I use for all of my spacers. They work great. I've made small dents from just a piece of leather before.
-
I have done the same as Clint, but with 1/8" rubber
-
I've got some of those also Aaaaron, but I'm afraid to use them with a heat gun. Do you have problems with them melting?
-
can you go down to the next ring?
No, I got too close to finish thickness and then decided to change the profile.
Josh and AA, I don't think any fibers were broken but??
I am gonna tiller it out some and then decide if I want to sinew it or not.
-
I've got some of those also Aaaaron, but I'm afraid to use them with a heat gun. Do you have problems with them melting?
No problems, but I'm using some good quality rubber gasket material I got from work
-
I get the now and then when doing some heavy tweaking, I usually just burnish them out our lightly scrape if the ring is thick enough and move on. ;)

Yes those are a pain. I try just heating them with heat gun and rasing the grain back up if not to bad. That one is pretty deep though. Arvin
-
I have seen several of those dents that held up just fine when left alone
but they add character that I don't like so well so I try to avoid doing them
I say keep going lets see what happens
-
Not sure what you tried but a wet cloth rag and some. Tin foil and heat gun might work?
-
You boys need to smarten up.
For 12 years I quit using heat. I been adding reflex, reflex, reflex, Beening tips all as soon as possable while green.You won't get those cinks when beening tips green.
Little early prep work cutting Green stave's into bow form. Your bows well on its way 4, 5.10 years down the road. when you get to it it's ready. You have a simi bow already cut into form. 1/4 the works you've already done. When you do it to it.
I know lots of people can't wait that long. But if you do you see what you been missing in your bow speed,cast and long jedituy.
Heat changes,damages wood sells. One there damaged there's no repairing them. This is why some woods take heat so much better than other.
-
Ya crooketarrow we are a bunch of dummies alright, thanks for pointing that out. ::) ::) funny I have never seen one of the magnificent bows you build ??? I would love to see some, also love to see some gnarly Osage that you tweaked and straightened green. ::)
Pappy
-
Thanks for saving me some typing Pappy! What do you do when you go out and cut 20, 30, 40 staves? Hurry up and work them all down? I'd rather have a couple of cracks then have 40 Bows have roughed out clamped laying all over my house.
-
Ya we are so dumb I really can't figure out why he bothers to get on this site, must just feel sorry for us and want to help us learn how to really build a good bow instead of the junk we build now. ::) ::) Sorry for the rant, but man some people. >:(

Maybe you dummies need to read the above again. Get with it pappy and Pauly.

Hahaha

Some guys seem to have all the answers. They never post any pictures of their work to prove it though.
-
I've seen a few flickers of his work. That's why I'm having fun with this, I take no stock in any of it.
-
I've had that happen. I just ignored it or maybe sanded the area around it it a bit. I guess I should have been worried. :)
Actually, The Dean uses steam on green wood to do his bending as described in Hunting the Osage Bow. He does have a nice way of putting things though.

Ok guy's... >:( I'm calling it a cheap shot making fun of a guys spelling....Really? I don't think it's funny at all >:( This is not what PA is about...

Its simple, Don. When a guy throws a few punches? He'd best get his hands up.

Don
Don, 99 times out of a hundred I would agree with you. I've never cared for people taking swipes at someone for their spelling, grammar or other handicaps. But not this time. He basically said that everyone that heat bends wood is dumb. When you start casting doubt on other people's intelligence you kinda open yourself up to the same. Also consider that this is far from the first time he's acted in this manner. Just the way I see it. Josh

"You boys need to smarten up." - crooketarrow
-
I kinda look at what he said a little different. When I say stuff like what he said its ment to be taken lightly, not as an insult. Seems it may have been taken wrong and everyone was quick to jump on him. I hope i am never mis understood because looks like it would be hell to recover from.
-
Kinda got to go with Don and Sleek fellas....even if ya took it right or wrong, Pappy slapped him down pretty darned good....I'm throwin the penalty flag for "piling on" , I mean ya knocked him down, stomped him some, how much more ya need?
rich
-
I agree with half eye. Let it go.
My brother calls me stupid all the time and I often return the favor. So what. I know he loves me.
Anyway, he's right. :)

Perhaps, but this is his main contribution. Telling everyone that using heat is dumb and only he knows better. When you label a whole group like that you have to expect retorts from all of them too.
-
It wasn't long ago that he said that anyone who puts a backing on a bow sucks at picking out staves and needs to learn how to tiller. He makes posts that in my opinion insult almost every member of this forum. Nobody was making fun of his spelling until he starts making comments like the one in this thread.
-
I for one appreciate some healthy mudslinging as long it's a similar approach from both sides. No need to bully but "longjediuty def" haha that's good stuff, makes a day of mediocre red oak grading go by much quicker.. SWWWEEEETTT.. lol
-
I don't think there was any bullying going on. All I know is where I come from you tell someone they need to smarten up that is taken the same as someone being called dumb. If he truly wanted to enlighten us then he would have gone about it in a completely different manner. So I say put your money where your mouth is and show us the way. Plus when you put something out there for the world to read be ready for the world to answer
-
If you ignore it..it might go away.........................not the dent ;)

DuH, I got a wooden spoon :o
-
Now that's high quality H2O.
Well I believe the guys that have had them last without problems but I took the opportunity to use up some sinew I had ready and be very sure it's gonna last.
-
Ya know, that aint gonna be bad. Nice decision.
-
If it fails, I believe it will be my fault not the materials.
-
I doubt it will unless the wood just cant handle that much sinew.
-
I have a dent from dry heat bending in a 55" osage bow that I sometimes string and shoot but always predict an explosion at full draw! Now I think I will back it and make a more trustworthy bow out of it.

Not mentioned these days, but I have done that to the area around a dent and then just finished up the bow. I've done this a half dozen times and had no ill effects.
I heated areas with dents like that one and polished them with a bottle with some success. Press hard and don't expect it to become completely invisible.
-
I did and for that I apologize , sorry, should just keep in mind everyone has there on opinion. Now back to the bow, looks like you got the problem solved. Nice fix. Pappy
