I have done a lot of reading on this forum and elsewhere about various elements of construction, and either I'm missing it or just can't find it at the moment. If I am making a bow from just two pieces laminated, is it advantageous, detrimental, or rather a wash to flip the board going on the belly side of the bow? As mentioned, I'm new and all I really have to work with is board stock. I've got a decent hickory board in the garage and I'm debating whether to leave it in one piece, or saw it through, flip the belly half of it over and reconstruct. Heck, if I saw it through, I could even try out an inch or two of Perry Reflex. Included is a diagram for clarity, as it seems you guys do love visual thinking. I was thinking about 1/3 back and 2/3 belly. Thanks in advance. Brandon Last Edited By: BL Jan 20 12 2:45 PM. Edited 1 time.

I dont think it will matter either way unless you try to chase a ring for the back, then you will end up with a concave looking back that will require a convex looking belly. either way, do your best to keep one unbroken ring for your back. Edit: after re-reading your post I see you want to do a laminate, I thought you were asking about just flipping the bow upside down to make it a self bow. As for a laminate, again, I dont think it will matter either way. More experienced voices will chime in though I am sure. Last Edited By: sleek Dec 30 11 3:53 PM. Edited 1 times.

From a cabinet- makers point of view the flipped versions glue- line is unstable, cause wood tends to bend towards its back(outside). This will be more relevant for wider cross- sections but is a fact anyway. It seems that the Scythian bowyers have been aware of this problem, cause they´ve added wooden strips at the sides of the limbs. Michael

Am I gaining anything by sawing and re-laminating with some PR, flipped or not, or am I really just better off leaving it as a self-bow? I am happy enough building it any of three ways, I mostly am just curious as to the differences. So far I have that it shouldn't make a difference, or that it will be a little unstable if I flip it. (Although the stave I'm working with is a 6-foot hickory1x2 which isn't all that wide) 1. Leave it as-is, selfbow all the way! 2. Saw it through and laminate the two pieces back together just how they were but with a little glued-in reflex. 3. Saw it through and laminate back together with the belly piece flipped, also with a little glued-in reflex.. Thanks for the responses.

( I think it will work no matter what. ) Idea! I am going to get a stave, split it down the middle, and turn both halves into a bow, backwards..... the heart wood with the rings facing the wrong direction will be the back. Just to prove my point. Gimme a few days...

Posts: 63 Jan 2 12 2:11 PM Reply Quote More My Recent Posts	I ended up doing a combination of things. I did saw it in half, flipped it end to end as mike suggested. I was going to leave the regular belly orientation but I mis-marked it and took a few runs off the wrong side in the fray. So I made that the outside and ended up flipping the rings anyway. The cross-section is so small that the grain is basically a straight line anyway, so I think you are all right it won't really make a difference. Since you were so kind to reply, the least I can do it post my progress. I started a thread in a more appropriate section. Here's the link. http://paleoplanet69529.yuku.com/topic/48692#.TwIpufncD6g Thanks again for all the responses. Brandon
