Finally to the tillering stage. (accidentally deleted the pics) See pics at end.
I have never tillered a short sinewed bow with reflex so it is a bit different for me.
It is 49" NTN, 1.5" at fades and 1/2" at tips with osage overlays.
3 layers deer leg sinew with knox.
2.75" reflex.
What draw weight do you think I should reasonably be shooting for on this?
How she looking?
Thanks Y'all

On the right limb the fade to midlimb needs to bend more. The left limb needs to bend more in general and the fade and outer 3rd need to bend more. That's just my observation. You could probably get 65# on this, idk tho, hard to tell from just pics. The reflex looks great!
-
Got her bending to 24" draw but ended up at only 35# instead of 45 :o
Man, I am always coming in light!
So I am gonna put a thick course of sinew not quite to the tips to try to gain a little weight and to try to regain a little reflex too.
Not sure on the tiller but will wait for now until after more sinew.
-
Be interested to see how the addition of sinew works out on that one, have some short staves of that myself and don't trust my
current skill level enough to make anything more than a kids bow that short. I know your frustration with coming in under weight, been there myself on my last few builds. You sure are getting some bend out of that bow. Keep us posted, I want to see how this one finishes up.
-
She is really a bending! Looks like you have about maxed out to me. Hopefully the added sinew gains you a few pounds.
-
I slapped on a nice thick crowning course of sinew fading thinner toward tips and have 7.5# weight hanging under it now.
I have never weighted a bow with sinew and not sure if there's a ratio or formula people uwe to know how much weight to use or just personal preferrence?
How long does it need to stay weighted before I can remove weight?

I have been trying to slow down so I don't take too much wood off but it is hard for me to judge weight and it seems very heavy until all of a sudden it isn't and I end up wondering what happened again :o
Soon as there's more action I'll post some more pics.
Thanks for lookin,

Thanks Soy, we'll see in a couple weeks. I hate waithing ::)
Do people generally leave a sinewed bow weighted down for reflex for a couple weeks?

Heat temper that puppy! :D

I would love to but can I do that with the sinew on?

I doubt it.
Sinew and any animal material softens when heated
Try keeping it concentrated just on the belly.. and it might work.

Not worth the risk.

I am not to be trusted with a rasp :'(
I took this way to light and it gained reflex up to 6" from around 3" before I got happy with the rasp. couldn't get the limbs to even up and never tillered anything with reflex before. I just about resigned to having another kids bow but it seemed wrong with this having sinew and then covered with buckthorn bark. Lots of work into it and lots of firsts for me so I decided not to give up yet. Been over my head thus far so why not keep goin right?
I sanded the belly flat, found some straight grained ERC and cut out a couple belly laminations, and glued em on with TB3. The lams had about 1" reflex and after glue up ended up with about 2.5" reflex with the lower limb having 1/2" pos tiller at this point. Actually got rid of some twist n the upper limb too ;D
I have been reading about Perry reflex and don't understand it much but think that may be sorta what I just did?
-
What you all think?
-
If you are blowing past your target weight with the rasp, maybe you need to switch to scraper or sanding block earlier in the tillering process?
-
The only reason to miss your goal weight is getting excited an working way to fast there's no other reason just need to slow down

I agree completely. I get in a hurry when I get some free time and a few strokes and I have screwed it up.
I have a knife for a scraper and haven't been using a sanding block at all. I better get a better set up and slow it down. Thanks folks.
I think I floor tiller too light to begin with too and don't leave enough wiggle room by the time the limbs are even.

Got her done! Lots of work into it but it was fun. If I was an experienced bowyer I would say way too much time but since I am new and just experimenting and learning, I am happy with it.
ERC lamination cue to my overzealous tillering :o
Still only came in at 36# at 25" with a slightly positive upper limb tiller but I like to shoot it. Seems pretty snappy but what do I know?
Had 6" reflex before lamination and was real light, and 1" after lam with 0 after brace.
Osage tips, 4 layers sinew, buckthorn bark over the sinew and sinew wraps cause I don't trust my lamination so much.
Sisal twine handle
Hope you like. I think it is time to try some simple self bow ;D

Here goes. Thanks for lookin'
-
She turned out nice, db.

Nicely done DB, good lookin bow, good save and good for not givin up on it. PS: dont sell 36# bows short. Pope tested NA bows and one in particular was an Apache bow drawing just under 30#. and Apache's were real good at what they did,eh?
nice bow
rich
-
Nice!!! Got a sweet bend also. :)
-
That looks cool doobs !

Thanks a lot to you all.

Right on Half eye, Wouldn't argue with the Apache ;). I guess 36# could do plenty of damage in the right hands.

Thats a lovely looking bow and tiller seems sweet. Very pretty indeed.
