Title: R/D BBC Tiller check
Post by: NTD on March 27, 2010, 02:59:40 am

Decided to try to Coyote.  It is really a pretty wood and not too hard to work.  I'd like your feedback on how badly I butchered the R/D profile.

NTD I like the unstrung profile.. On the next one I would try and get the mid limb working a bit more..  ;)

HM, I'm not sure about my opinion.
I would like to see a photo on brace hight.

A braced pic would help but it looks pretty good to me. Listen to what David(knightd) said. He builds lots of this type of bow.

Well, I like everything about it. So there >:D!   Bookmarked, too, for March Laminates in the BOM program.

I think the tiller is great. There is a lot of reflex right at midlimb giving the illusion of not bending. I would be really happy with the way it turned out.
Coyote wood, or Macawood (Platymiscium yucatanum) is a slightly denser than Osage, it should be a good performer if it doesn't fret. Justin

Nice bow.  :) I would be proud of it!  I've always had trouble tillering R/D bows.  In your last picture it looks like ti might have some frets.  Might not be seeing it clearly, though.

Good looking bow. Probably has my first R/D attempt beat by a mile.

Well I've had a short string of bad luck...I was doing the final sanding on this bow and noticed that it has developed compression fractures.  How long will a bow hold up after this?

It depends on how bad the frets are, where they are on the bow and species of wood.
If it was me I would flatten the belly and take it down to about 30# then put another lamination on the belly.

   I built two from coyote and they both had compression fractures. Still shot well but you never feel the same about a bow once that happens. Lots of that tropical hardwood chrsals. Steve

Too bad it checked Nathan.  The bow and tiller look real good to me.  I'd keep shooting it and see what it does.  It looks a bit like Bubinga to me and I have seen that wood be either great or useless for bows and  by looks you wouldn't be able to tell.  Perhaps try a longer elb style if you have more wood left and see if it holds up better.

Its definitely bending to much in the inner limbs. You need more bend from mid limb out whether it's reflexed or not.

Maybe if I had worked the midlimb more it might not have fretted. ::)  Well I'm a work in progress, If I don't get the profile right on the next two I have in the works I'm giving up on the R/D profile.
