Backing Strip Q

[simk]

Hi All

Would YOU PERSONALLY use this (ash-)backing strip? I'm a little unsure...

Thanks for your expertise 

Cheers

How does the grain run on the rest of the piece? If it is straight and you can eliminate that(those) runoffs it should be OK.

looks good to me.. only backing strip blew on me had a pin knot mid limb... and thats where she blew... if grain is holding like in pic should be fine

Thank^s alot Pat B & Gutpile!
Pat: The rest of the piece is absolutely flawless. Still: Eliminating this run offs is difficult - Sure I will reduce witdth on the limb a bit on that spot but there will only be new runoffs created with that grain-pattern..!? I will also round the edges. But it still will be in the middle of the working section. I just rememberd a bow of Del's blowing-off bow on a similar problem not long time ago....

Not to forget: I have another backing strip, 1000% perfect

Cheers

that run off isn't bad at all.. when you reduce width to limb profile you're going to have run off no matter what.. should be fine IMO... good luck..gut

Where would the wiggle be in the bow? One of the advantages of a spliced bow is that it gives you the opportunity to cut your backing strip in half and maybe position the questionable part in the tip or grip.

Thank you DC: It will be in the main bending zone of a d/r angular bow - still in the deflex part i think. I didnt plan to splice as all my pieces are full length. If I did splice I could move the wiggle to the outer limb (but still bending zone) which for sure would be a lot less problematic. Still, my appetite for cutting and splicing again is not too big - I'd rather use my better backing on this one and then cut new ones. Would YOU put that wiggle in the main bending zone?

Just to clarify, you don't have to necessarily splice the bow, you could just splice the backing. Would I use it? Unfortunately I have no experience with Ash. If it was Maple, yeah, I'd give it a go. I would try to squeeze over to the right hand side(second pic). How wide is it?

[simk]

thanks Don. I never spliced  the wood is 46mm wide and the bow on that particular spot the bow will be approx 38-40mm wide. still I think this piece of wood deserves the best possible backing (changed my mind). why use No2 when you have a much better (-;

If that grain wiggle would end up in the bending portion of the limb, I would not use it.

What's the grain doing on the side of the strip at the same point?

This is the problem with quarter sawn wood. The grain violation doesn't look too bad but that is a game ender. Go and read the section about selecting boards in the TBB (vol 2?). If choosing quarter sawn wood you must make certain that the lines run dead straight because even a little meander signifies quite severely cut fibers.

That's fine unless you are making a 100# flight bow.

What was the shape of that tree before the board was cut Del?
