Red Oak Boardbow Build Along

[hova]

disclaimer , thats not my pic , or my shop .

and a side note/edit , is that for resawing like this , you want as wide of a blade as you can get. this gives the blade better tracking. also , you want a blade with more of a rip tooth than a crosscut tooth. rip blades are like chisels , crosscut are like little knives.

Thats pretty cool! Thanks!  And this is used for cutting your own laminations?

well that was my mistake for not looking into it more i just saw a picture from a woodworking supply online and assumed they knew what they were talking about   :D  i can see that your saw would give you a lot more control over the cut which is what is needed for precision cuts

they called this a frame saw which is basically the other image with a fancy tensioner bar instead of a string

yeah there is a big discrepancy between the terms. the saw you have pictured can be listed as a frame saw , bow saw , or stretcher saw. personally i think it is a bow saw , because technically a bow saw is stretched , but whatever...


i dont recall how i came upon it , but a lot of boat builders use it , basically to get two boards (or more) from one.

the one i showed lacked an alignment block. some of them have pieces on the end of the blade , with a vertical , or angled slice in it , that the blade sits in. this keeps the blade from twisting. one variant had the above mentioned angled slice , and was used with some kind of fence to produce veneer size cuts.

im waitin on some wide bandsaw blade from a member , once it gets here , ill do a build and use-along so you can see it.

theres lots of stuff on the net if you cant wait.

i started looking at the different types of "frame" saws and different blades and man are they proud of their stuff especially those japanese blades   :eek:       lol...found some cheap blades for around $10 but i dont know how well they would work...definately gonna work on building one of the "bow" frame saws for camping and cutting brush and wouldn't hurt to make the other to have around the workshop for different things

edit: i did find a forum thread on just what we were discussing about the saws and he shows multiple examples of the "frame" saws

Alright...I have removed the wood that I needed to from the sides; it's starting to look like a bow.  It's time to start removing wood from the belly now.  At what point after I start removing wood from the belly do I need to put it on a tiller tree and go from there?

fly: you are looking for "floor tiller" . take the stave , put one end on the floor , angle the stave , and hold the other tip. then push the handle , to make it bend sort of like a bow.


you want it to bend evenly , a couple of inches.


some people put a tight long string on , no brace height , and tiller a couple inches.


others just go from floor tiller to brace. being new at this , i would get the limbs moving a bit on floor tiller , then tight long string it , and use a scale so you dont make set happen before you even get it braced.

edit: that site you posted might has the veneer saw i seen (saw) , but that frame style pit saw is friggin awesome. i hadnt thought of something like that.

Thanks Hov...so I just start shaving wood off the belly in even increments the length of each limb until I can get it to bend a couple inches with floor tiller?

[SubXeroArcher]

yea but be sure not to take too much off at a time and once it starts bending keep an eye on where its bending more and try to avoid those areas until you get it bending evenly...you dont want to keep taking wood from the parts bending already or you could end up taking too much off

[hova]

im still new , but i mark the side of what im working on , a little at a time , but youre still going to have to remove a bit of wood...


pictures would help us help ya a little clearer , but you just want to get it to start moving if youre going to use a long string.

PIC bring out the veterans like a moth to a flame. Also I have not seen anyone tell you about the tillering gizmo. If you have never heard of it stop right now! Do a search on this site read about how to use it and make one. The start tillering. It will help you more than any of us.

yea that is one tool every bowyer needs to have at least one of lol...the link to it is below and it will cost you maybe a whole 10-20 cents to make if you dont have a nut for it because im sure you have a pencil and some scrap would laying around somewhere   :D
