Im building two kids/youth bows right now. I have a red oak board and bamboo to back it. It alone wouod make one self bow but two if I back it. Looking for 30#@28. Idea being its always a shootable bow as they grow up. So, I want to avoid set, for obvious reasons. Im making them pyramid shape for ease of tiller. Do I trap the back or is red oak strong enough in compression I dont need to?
-
Sleek you xan probably do it either way but i think personally i would trap it
-
Ok bubby I will then. Thanks.
-
Plus one on trapping. OneBow

enjoy :)

Trap it to half the width of the back.

I saw these two bows Sleek built and even got to shoot them! They came out very nice. They are not screamers by any means, but they shoot nice and draw smooth as silk. I actually shot better with the left handed one! I have some nice pix of them, but I should let Kevin post them.

I will get some pics of the build up later today. But if you would post your pics that would be great!
The bows took 2.5 inches of set even with back trapping. They made 30@28 and 33@28. Smooth shooters, llts of funto shoot. The only arrow I had was almost 500 grains so that probably slowed them down some. Good target penetration however.... certainly kill any candle that gets in their way! ( we were shooting by candle light and inhit the candle we left there in the morning on accident .)
Red oak doest like boo. Lesson learned. Perhaps if I had glued in 2 inches of reflex that would have helped. However, set helps with ease of stringing for an 11 and 8 year old.

Based on your experience, will trap my maple backed red oak.
Wish could have stuck around to see them shot! As it was, about halfway home I pulled over and took a snooze. Got home a bit after midnight.

Thanks Eric, those pics are great. The tiller is a little off on both bows but I only had a little wood to work with.
-
Very nice Kevin, wish I could have shot them to. They turned out beautiful. Sorry I wasn't able to help with the finish work on Sunday. They look like sweet shooters but their no 199! Sure would have rather worked on bows than play plumber.
Mike, glad you made it home safely bud. And thank you for the beautiful hickory stave. Eric thanks for all of your hospitality and help with all of our bows. Maybe next time we can get your lam bow shooting. Can't wait till we can all do this again! Patrick

How wide did you make the ro sleek, in my experience with it i would have gone close to two wide at the fade most boo is 1-1/2" wide giving an easy trap and toast a little reflex into the red oak not much an inch or so then glue it up with a little perry reflex and it should have come out flat at the worst, nice looking bows

Or just use osage the next time and get waaaay better results,and a narrower "sleeker" bow ;) :laugh:
But those will work n do well for a couple of kids that wont care about the stuff us bowyers worry about ;)

I think he might have beat the problem of some of the set issue at the same width he has if we had taken time to toast the Red Oak belly on each bow real well, ...but there was a birthday deadline, and there really wasn't all that much set. If the set issue gets any worse, that might still be a reasonable option to pursue. ...but it probably won't. The kids will likely not ever pull the bows out to the 28 inches they are tillered to.
So, ...yes, the performance is not optimal, but it is fine. Both bows were able to bury the target arrows 8 - 10 inches into the target block at 20 yards, and more than that is really just over kill for a kids bow. Would I hunt deer with them? Certainly NOT! ...but I could give rabbits and squirrels heck all day long with them. >:D
A well designed tool is not necessarily the one that performs at the optimal end of the possible performance for the material it is made from, rather, a well designed tool is the one that meets the purpose for which it was designed effectively using the materials that were selected.

Well said buddy. They will do exactly what they were made for. Make 2 young kids very happy and introduce them to archery. Plus they won't break on them. Patrick

I wasn't criticising the bows they are fine looking bows, just trying to address the set that sleek was talking about

Yeah - Sleek was kicking himself about the set too. It was kinda an odd deal, ...again, 'caused by hurry. Sleek actually glued up the boo on either side of a single Oak board and then ripped the board down the middle after the glue had setup. Hopefully he'll provide some pics of that. I would've ruined one side or the other, but I guess Sleek is pretty danged good with the band saw. This method prevented being able to glue in some reflex from the outset. Then, with not having time for doing the belly toasting, some set was just gonna happen.

When you glue up like this, you cant put in reflex, but boy it saved me time. I dont have a working bandsaw so I had to glue it up on both sides to dry while going to hang out with Patrick and Eric's to use the bandsaw. As you can also see, I didnt have much width to work with on this glue up. I left the first 6" past the power lamb parallel the went pyramid on the taper. The glue is tight bond III, except the handle. I used ca glue at Pats suggestion to save time.. Worked great.

Full draw for the lefty. He is 11, and it seems he is managing just fine.

And for the righty. She is 8 and lools like drawing that bow is not a problem. She struggled to get it back that far. I told her not to let her ear get in the way on the release.

Drew the line free hand to rip it in half.

This has a red oak power lamb. The other got sapele.
-
Thats all the pics I got for them.
Interesting thing to learn. 30#@28 is a good weight for kids to draw at all ages of life. the older they get, the stronger and longer their draw. A 30# bow@28 seems to keep up with that.
-
I am making a boo backed red oak right now too. Red Oak was the only decent board I had and wanted to make one while my staves are drying. I rushed the tiller and it got a decent hinge that ended up lightening the draw up way more than I wanted. I am going to treat the belly and cut an inch off of each side and see what I can get out of it. Def learned a lot from it.
I am impressed with yours though. They look way nicer than what I've got so far. And I would have loved to have them growing up!

You could certainly give them heck.... if you concentrate a bit more on tjat left handed shooting of yours ;)

I appreciate it bubby. But as has been stated, time cconstraints and building methods as a result prevented much of the options for set control. I figure later if they want stronger bows, a belly lam of osage may be in order. Then things will improve. For now, they will send arrows down range very well.
-
Eric I want to thank you on here also for your help on finishing these. The strings, the materials, and the deer tine arrow passes. Not to mention food, drink, conversation and good all round company. Thanks buddy.

My pleasure entirely!!!
