I have a pretty large osage stave. It is 4.5" at the bark or back and 5" from the back to the inner point. I think I should be able to make 2 bows pretty easily. If so, how do I split this baby? Just pick a growth ring and split it with a wedge and maul? Is the outer piece better for making a bow or the inner section? Or does it just depend on the amount of growth rings per section...?
-
Oh yea, for sure. I would split it on a bandsaw after I got the bark and sapwood off. I personally wouldn't want to do it any other way.

Dan, do I just try and saw with the a growth ring? Or should I just saw through the middle of the stave and go from there?
-
Yea, find where you want to cut it and draw with any squiggles or snakes the stave may have. I have bought quite a bit of staves at MOJAM that I was able to slice into two.

if its thick enough you could take a belly split by following a growth ring
if its wide enough
split it and folllow tha longitudial grainr not real unless you cane fllow grain real good by hand and are skilled with a band saw i dont recomend using that to split it
you can ruin wood real quick if you arent real carefull with power tools
ive taken several belly staves from thick pieves of wood like osage
where i live its very very very hard to aquire osage(it doesnt grow here)
so i take all precautions with it as i dont want to waste it
but its your wood,take my advise for what it s worth
pretty much nothing to most folks :D ;D

I want to utilize as much of this stave as I can. A man from Missouri shipped it to me. I don't think it grows here in Oregon. So, if I understand, I should go down on one end about the 2" or so, find a growth ring and set a wedge there and start splitting....?
-
Careful with that is it the finer ringed osage. I have had awful luck with belly spits with that stuff.

That's what I would do too. Split off the inside of the wedge(piggyback) for one stave and down the bark side for two more. You have plenty enough wood to make 3 staves from one that big.
Can you post pics of the ends and the back of the stave. That will help us help you.

I'll post some pictures tomorrow. Thanks guys, David

I do a lot of billet splicing and save the triangles I cut out for the splice to knock core splits out of a stave. Perfect little wedges for splitting, about 4" long and flexible enough to do minimal damage to the wood. I get a split started with a steel wedge and do the rest with my wood wedges.

Eric, that's a great idea. I think I have some hardwood scraps I can saw into wedges. Thanks, David

Like so? I've been wondering about such a thing myself.

Thanks for verifying with an image. David

I bought a nice stave from a guy in Missouri on ebay the mail women looked at me kid of funny when she had it for me stand up and she said is this a tree it sure is heavy. I know a guy with a wood shop he makes mostly mantle for fire places and has a band saw with a big blade like two teeth per inch almost a sawmill blade and we feed that stave threw that saw I split a stave once and it tracked way off and i only got one stave anyway. I used a circular saw once and cut a line down the back of the stave and had a good split but the saw was not made to do what I did and lucky I have strong arms and good reflex because it jerked and pulled if you didn't go really slow.

Here are some pictures of the stave.

If the stave is that size for its entire leinght then you have plenty of wood to split it like Frode suggested with the drawing he posted.
Clean the sides up so you can see the rings all the way from end to end on both sides.
Take a pincle and mark the ring you want to be the back of the belly stave.
Start you split at least one ring above the ring you want to be the back. Two or three rings above if possible.
Drive two wedges into the end of it. Making sure you follow the curve of the rings. Once the end opens a bit drive small wedges into both sides of it. Leap frog the weadges down the leinght of it. GO SLOW.
Once you get the belly stave off. Clean the back of it up ( chace a ring ) and then seal the back of the belly stave.
I would also seal the belly side of the big stave. Osage will often crack on a wide belly like you will have.
If this wood is good and dry you can also split the big stave if you would like. If it is not dry let dry before splitting the big stave.

Thanks David. The stave seems to be pretty dry. I'll have to split it to really know. It is 75" long and does have a little end checking. But with the length I can saw that off. On the other end I can go to 66" and it is 4" in width. The pictures are of the larger end. With 4" I should still have enough, won't I?
-
Don't shorten the length until you clean the back up and finish your core splitting. Osage always has a surprise waiting for you under the bark and sapwood, seldom a good one. You may need the extra length to work around a "surprise".
-
Will do Eric. Thanks, David

what ridge wrote about cleaning up the sides and inspecting the rings is very true,i see alot of people buying staves after just looking at the ends. you can run into one of those big surprises that way to.
