Title: BM bow?
Post by: sleek on November 17, 2015, 06:20:53 pm
Lost motivation for a while but im trying to put my nose back to the grinder. So I have a slat of maple from home depot and a strip of boo. Also a thin strip of erc sap wood as a core wood perhaps.  Any suggestions on this combo? Im thinking 50@28 62"ttt deflex reflex.

62" TTT is kinda border-line short for an R/D with that weight and draw length.  ...but I know that the surest way to get you to do something is tell that it's not a good idea or can't be done that way. 

SO, I'll just wait for you to put the PIX up in about an hour or two of exactly such a bow.  Not sure how you're gonna get the glue to dry and cure in that time, ...but I expect you'll find a way if someone just tells you it shouldn't or can't be done!  :)

BTW - I really like the idea of using the ERC sapwood for a core.  It's super light weight and aught to be an excellent core material.  Make sure you taper it enough to leave plenty Maple for the tillering process on the belly.

Out of curiosity since I've never done a Boo-Maple bow, do you trap the limb?  If so, how much?

I did, my first Boo-Osage bow this year and while it came out okay, it took a little more set than I like and I wish I had trapped it just a little (I think 5 degrees would have been about right ~8::7 ratio)  The Osage had an SG of around 0.76.

The bm bow build has begun. ( Yeah, I'm having fun with the name ) I tapered the core, and got it pre tillered. I question the wisdom of that, because a thicker core at the tips makes the tips lighter, considering the core is cedar sapwood. Next one I build I wont taper. Then compare the differences. Right now I am gluing up the handle. Going to glue the handle on, then I am going to deflex the glue up out the handle, and reflex upward towards the tips, increasing the reflex as it gets closer to the tips. Of course, this is all a fluid plan, I may change my mind in the middle of it all.

I still have to shape the handle but the glue lines came out satisfactory.  I think I like the color pattern.

I need to tweek the brace shap still. I think im going to come in light weight on this one. Maybe 40# if im lucky. I think its gonna be a dog honestly. Already an inch of set and it took that floor tillering. I have the back trapped to 50%. Maple doesnt like bamboo. Note to future readers.

Yup. Crappy bow. Got to 27" ( not this pic ) and the maple gave up. Started to chrysle. Waiste of time and materials.

Looks great sleek, good luck with the build

Thanks David but the bow is a flop. Way too much set far to early on. Took a total of 5" of set. I wasted good materials in a poor combination. Never gonna do that combo again. It came out 40#@28 and shoots like a wet noodle. It would make a wall hanger if one felt so inclined I suppose.

Ha, didn't see the last posts. I'd wonder what would happen if you did a deep heat treatment on the maple before glue up, if that would help the belly take the strain... Or maybe maple just doesn't go well with boo. OP hardwoods here in springfield had some clean yellowheart that might make a nice belly. I can get you some of that rock next time you come up too.

Some yellowheart would be awesome.  Im going to be there December 5th and 6th.  I'll be staying at Pats place as usual. We can meet up.

Your a good sport sleek.Sorry about the bow.It's hard to argue with a boo back,maple core,&osage belly,but how about a hickory back,black cherry core & an osage belly?

a total of 5" of set..... :o   What a shame that bow looks sweet.  Maybe back the Sugar with Hick, white oak or something else I guess the sugar dont like Boo.

Certainly anything but boo. I shoulda listened to blackhawk but if I had, we wouldnt have learned now would we?

Lucky though these things are a cinch to build. its just bamboo isnt exactly easy for me to get.

Walks away mutter..... stupid chickenhawk.... shoulda listened..... smarty pants... etc....
