Title: Hickory backed cherry?
Post by: Thwackaddict on June 29, 2010, 02:33:33 am
Any one ever try backing cherry with hickory? I have some old,old cherry that i'm dying to try backing it with either hickory or maple.Any pointers?

I would think hickory would way overpower the cherry. I am slowly working on a maple backed cherry now and have heard that combination works well and shoots very fast. You'll want to leave the cherry wide to spread the compression load or it is likely to chrysal and/or fail.

I agree, the cherry will most likely be overpowered.  Hickory is strong in tension.  Cherry is weak in compression if I am not mistaken.  This would make a bad combo unless you keep the backing very thin.

I've built three hickory backed cherry. Two chrysaled and I reworked the last one by thinning the hickory backing to 1/8 or less. Still shooting that one.

Cherry/hickory is a combo that has been used a lot in the past. Apparantly if you can get one shooting, it makes a good bow. As has been said, keep the hickory very thin.

I made a hickory-backed cherry bow. The hickory was about 1/8" thin, and I trapped it a little. No problems. The bow is still shooting fine, at around 52 lbs@28.

Ash backed Cherry seems like a fairly well balanced combination.

1/8" ring violated hickory backing, 70" ntn, 60#-65# @ 29", wicked fast with hardly any handshock- 200 arrows so far. the finish isn't dry yet, so no full draws.

i've had maple backs not quite hold together, so i tried the thin hickory instead- so far so good....

I hate to disagree with you guys, BUT hickory makes a great backing for cherrry.  Cherry is strong in compression, what causes the chrysaling is poor tillering.  Take the tillering slowly and don't over stress the wood too early.  I do agree with keeping the hickory thin, just under .125"  (1/8 inch).  There is no need to go wide with it though, keep the width at 1.5 for most backed bows.  Other wise the core/ backing ratio gets out of whack.  Also ash and maple do make great backings for cherry.  here is my latest ash backed cherry.

thanks ken you too sulphur,what thickness should the belly be?I'm at 1" right now before the hickory goes on.As this will be my first backing attempt what am i looking for backing wise?Board or big thick stave?Tight growth rings or big thick ones?
Title: Re: Hickory backed cherry?

thanks, my local hardwoods dealer has been known to set aside good bow wood for me from time to time. i've had the cherry for a year or so. the ring violated hickory is ripped from a flat sawn board to show a few islands (i've gotten away with it on 4 or 5 bows now). i'll post pics when i'm done with the tru oil.

unless it blows up......

Post by: Thwackaddict on June 30, 2010, 12:12:17 pm
Ok,thanks man,we'll hope it doesnt i would like to see that.So i just look for a board with nice strait grain.

thwack all my backings have been either hickory or ash quarter sawn , some on here have posted about plain sawn backings i just haven tried it . if your looking for a hunting weight bow start with 1/2 inch cherry before backing is on and bring it down from there during tillering , make sure to not stress the bow at all if you have dips or low spots ,smooth all the way even during tillering. this should get you a 55 # hunting bow thats fast and sweet shooting .keep your tips light

I've made several hickory backed cherry bows. All flat bows, with limb at fades 1.5" - 1.75", with 1/2" nocks. I kept all of them <50#, with careful perfect tillering. No frets. All were good shooters.

Ok guys one more question before i start this build.Yesterday i came into some prime cherry and a huge maple board,True 2X10X8.The cherry has beautiful contrast between heart and sap wood running full length of board.Have you ever used heart for back and sapwood for belly or would it really matter?I will try and get some pics posted monday.The maple has some pretty thick growth rings and the cherry is pretty tight.I think its going to make some beautiful bows.

I've never done a wooden backed bow. If I had some cherry I'd throw on a backing of burlap or linen. May be silk. I can't offer more than that. Rawhide would be nice looking on cherry.  Sorry. :) Jawge
Title: Re: Hickory backed cherry?
Post by: Thwackaddict on July 03, 2010, 02:34:05 pm
Thanks Jawge,I may do one and back it with rawhide,i figure i can get 4 or 5 bows outta this board.May have to hit your site and check on linen and burlap backin as i have no experience with that.

i have two quarter sawn cherry rips that i plan to test against the hick/cherry bow that i'm finishing up right now

i've wondered about a sap wood/ heart wood cherry bow myself (maybe with a little rawhide insurance policy), but haven't had the right wood to try it out with.

i'm a little gun-shy about maple backing cherry lately. i had the tiniest little wrinkle in the grain of my maple backing blow after a good 6-8 months of shooting (and i cried). be sure that the maple's grain is absolutely trustworthy before you glue it up

can't wait to see the pics,
Rob

i have done the sapwood heartwood combo with good results.  I am not sure there is as much difference as say hickory.    I always get the straightest grain boards of cherry i can find, that may something to do with keeping it together.  If you have maple i say go for it.  .125" thickness should be ok.

Elk country-Thanks for the heads up,The Maple Has some really thick growth rings and seems to be pretty strait grained.I feel like a kid a christmas.I will get started tommorow and post pics as i go along.I am so excited i can hardly contain myself.Ive been outta work for a few months now and wood is hard to come by so when i came across this wood i bout cried.I think i can get 5 or 6 bows outta the cherry and i got enough maple to back 20. ;D ;D

Sulphur-have you tryd hertwood for the back and sapwood for the belly?I'm anxious to see if it will work.They are goin to be beautiful if i can get em to hold.

Thanks guys.

Post by: sulphur on July 04, 2010, 03:12:47 pm
no, my board are usually plainsawn and i use the outer sides.    so it have a little sapwood on the bottom limb that ran done one edge.  sapwood on the back and heart wood on the belly should be ok.  the sapwood will be covered up by the maple backing so all should be go.

Ok, thanks!  I will post some pics tommorow!Gonna rip em down tonight.
