Title: Board bow tips are 1/4"..too skinny to work?
Post by: Zradix on April 09, 2013, 02:06:00 PM
Hi Guys,

Because of making a mistake with a power tool...    :knothead:  

The tips on my pyramid style oak board bow are only going to be 1/4" wide.

Even though not finished, I can't really have them any wider as my deep cut mistake was near the tip.

Can I even put nocks in such a narrow tip?
What would you recommend doing?

Thank you in advance.    :thumbsup:    

John

If I knew what a min width was I might be able to cut the strings nocks down the limbs a ways. But they taper so slowly I'd lose a lot of length.

The board is 68" long right now.
I'm working for 45#@28"

I'm thinking a tip overlay of some sort might add some wood and make it stronger.

I've seen here recently (recent for me not a new post), that one guy instead of adding a true overlay right to the back, he cut the tip of the bow of diagonally and added a tip that way.

I was thinking I could do something similar but have the new tip be wider and more accommodating.

Along these lines...

I'd rather hear I can just back the bow, cut some nocks (not touching the back) and be good to go.

Maybe I'm just fearing the unknown and getting worked up over nothing.

Cut 1" off each end and the tips should widen out enough to add overlays.

Thanks Chris.

1/4" are just too narrow eh?

At 1" down they'll be 5/16"..maybe 11/32"

Really wish I could just leave them wider as I haven't finished the taper yet..but my damn mistake is right there..

You could make wrap on nocks. Just wrap some thread or serving around the tips and glue it.

I would do what Pearlie boy said, cut an inch off and then add overlays. If you do it like 4est did, you can gain a little advantage with a slightly recurved tip while adding strength through the ti being thicker belly to back.

If I remember these are 5/16" osage stave and not a bd ......but I think you'd get the same results...I used an IPE scrape to replace a broken horn nock...

1/4" is a little narrow. It probably wont break as long as they're fairly deep. The main problem is when teh limb is more narrow than it is depe is they tend to be more prone to twisting and bending slightly sideways.

I'd do as Pearly Boy said.

if it was me id probably not cut an inch off, and just make my tip overlays good and strong.

tips that are narrow and thick are better than wide and thin from a performance standpoint... at least thats what i think i read in the TBB, need to get that out and read it again.  it might be a good idea to leave the last 3 or 4 inches of the tips at full board thickness... or at least 1/2"... and make your tip overlays 2" long. im just guessing though.

I tried! lol
Just a stupid inexperienced mistake.
Table saw..bottom of the board gets cut farther than the visible top.

Thanks for the help guys!
