Mulberry warbow in progress, one limb reflexed one limb straight-ish...
toomanyknots:
Here she is on the long string. Got a nice white back and an orange belly. Got er ready to brace right now just this morning. 77 1/2" nock to nock right now, or something like that. Shooting for 100 @ 32". I've pulled er farther than this, just didn't get a picture. You can see the reflexed limb is on the left in the first picture. This is one of those things where I tiller the reflexed limb a bit weaker than the straight one to bring them together at brace and fulldraw. Eventually, (or usually) the reflexed limb will lose almost all it's reflex and end up matching the straighter limb. The way I have currently been evolving with making warbows, is to start with the bow longer than it needs to be with self nocks, and I just get the heaviest weight I can get out of it without killing myself. I hurt myself pulling this guy trying to get it heavier than I usually do recently, (not bad or anything, it's better now) but they typically come out at 80# @ 28"/ 90# - 95# @ 32" (yes I am a wussy little weakling, and for that reason I have started doing it this way instead of killing myself getting all it tillered at much higher weights), but I get a perfect tiller up to the draw length I want and do almost all the sanding and such before hand. Then I just cut an inch off each end if it's dramatically under weight, and a half an inch after that until I am about 5# over weight or close to want I want, exc... I get it all sanded and perfectly tillered because I seem to (not matter what I do or how I try to protect them) scratch the nocks when sanding. The pair I bought from rudder bows is already a bit scratched from shody polishing, (of course way better than I could do though) so I really want to make sure to keep em as nice as possible. The cross section is of course a fat flatish wideish at the handle d. This wood is cool! After sitting on the tiller tree pulled pretty far and then undoing it, it has a bit of set, but then it pulls itself back slowly like sinewed bows do, so in like 20 or 30 seconds of slowly moving it's back to about 4" reflex. ;D
Edit: There is also the last little remnants of a hinge I haven't fixed 1000%, whoever finds it get 50 points. :)
toomanyknots:
Welp, here is the first brace:
I'm actually glad to see a hinge and some flat spots. Gives me a reason to bring the weight down some, I fear I am way over weight with this one as it is. I didn't want to brace it at a full brace so soon, but the string didn't stretch as much as I anticipated.
toomanyknots:
Ok, here it is with a 4 1/2" brace height. Been trying to take care of the major hinge on the right limb in the picture above as well as the flat spots right of the hinge in the lower limb and left of the hinge in the middle-ish area of the bow.
Pulled to 22":
I haven't weighted it yet. Soon as I get the tiller where it looks good and is in no danger of over stressing hingy spots or anything Ill see what it's pulling. I have found out if you keep getting hinges in one limb, then just the normal method of taking wood off the parts that are around the hinge and not touching the hinging spot will not work by itself, as if you keep getting them in one limb more than likely the other limb is a good amount stronger. Whether it's stronger simply due to the hinge in the other limb or what, it is still most likely alot stronger. So if you don't get the limbs evened out by weakening the stronger limb to meet the weaker hinging one, things will only get worse no matter how much you tweek the hinging limb. Also, I didn't get the camera angle just right on these pics, so tiller might look off, or be off and look good, exc from the slightly turned angle. If you look close enough on the right limb though you will see I still need to take off some wood on either side of the where the hinge was (IS STILL).
toomanyknots:
Ok, here it is braced at 4 1/2" pulled to 29".
The limb on the right is actually stronger even though it's hard to tell in this picture. (Or is still stronger, I should say.) I keep switching the bow around on the tree, you can tell it's turned around because the two big knots aren't showing on this picture like in the pictures above. The limb that had the hinge is on the left now instead of the right. It is pulling 90# at 26" right now. Set is 1" on the limb on the right, and 1/4" on the limb on the left. (right limb was the straight limb, left limb was the reflexed)
toomanyknots:
Ok, finally braced to 5 3/4"...
Pulled to 32",
I am pretty happy with the tiller so far. There is a bit of a stiff part on the limb on the left, right off the middle of the handle and than a very slight sharp bend after that, but besides that, I am pretty happy. What do you guys think? Here is a link to a youtube video of me pulling it to 32":
