Hi there! I´m working on this serviceberry bow, 70" ntn, limbs parallell for half of their length. Comments on tiller so far, 20" draw?

Very nice. Looks great. Jawge

Just a cat's whisker more off the left limb?
Del

Looks good so far....maybe the left limb is more stiff in the mid-limb area...unless you are after a lower limb positive tiller that is.
half eye

I think you are right about the left limb, will scrape a bit more mid limb. Should it be more elliptical, more bend towards the tips?
-
Guess my eyes are different,looks pretty good just a little flat a few inches out of the fad on the right limb for 6 inches or so. Overall nice. :)

Different eyes are good! Think you are right.
-
If those horizontal lines on the backboard are true then the string on the nock of the left limb just about touches the line but the same point on the right is deffinitely lower.

i agree with Del, 1/2, & Pappy- left mid limb & right limb just outside of the fade both look stiff
that's some pretty straight looking serviceberry!
-
Hope I'm, not harping on here, but if you have a grid, you may as well make use of it.
Third horizontal line down from the handle, follow it to the right, you cross 6 vertical lines and nearly get to the 7th to get to the limb.
Following to the left, it's just over 7 lines.
please ignore me if I'm being a bore here... :-[

(BTW, I do realise bows aren't symetrical etc, I'm just trying to point out some tips...ok I'll shut up and scamper away to my secret cat nest now ;D)

Del, I asked for comments, so that is what I want from you! No need for appoligies!
-
left limb is a little stiff. but looks good.
-
After some heat treating and dehydration, I´m on it again. 25" now. I´m greatful for any comments!

Left limb - mid limb slightly stiff? It's awfully close. Man, your workshop looks really nice - I wish I had that grid system, pulley, spring scale, and staves up top! ;D
-
That's soooo much better.
I bet you feel a great sense of achievement.
Del
-
Parnell, You might be right... But I think there is a tiny bit of reflex in that section, and a tiny bit of deflex on the same place in the right limb, or? Yes, I´m very pleased with my workshop :)
Del, yes it feels much better now! But I´m still open for ideas to make it better!
-
looking good...
the left limb is slightly longer. is it the top???
the two limbs are bening to the same line now, and whilst the left limb has got a straight section around mid limb, if it is the top limb it will be weakend further when the bow is drawn from the right spot (rather than in the middle).
off set where you're pulling the string from to represent the place it will be pulled when being shot and work on it from there. no point drawing it from the centre to tiller as it wont be shot that way.

Otis, the left limb looks longer in the picture, but isn´t. I had to go out to my workshop and meassure it, to be sure...
-
I am still a novice at tilering. But does anything think the inner 3rd of the right limb needs a bit more bend? Seems teh middle 3rd is bending quite a bit. I mean I am noone to talk. But curious.
-
I agree. Looks to be getting a bit whip tillered. Get the near handle wood moving out to mid limb. Jawge
-
Finally finished this one. 48#@29", 70" ntn, finished with tar and paraffin. And, while I´m at it, I post some pics of another bow, hazle, 48@29, 66ntn, inspired by mollegabet. It has some propeller twist, so the tiller looks a bit odd, but when I flip it over, the odd looking limb looks better, and the other one odd. Hope I got that right. Anyway, here´s the pics:

The mollegabet, and a handle from the serviceberry one.

Blimey You've been busy!
Del

:) Not that busy, the mollegabet is a couple of months old.
-
that mollegabet looks awesome!same with the other one great job!
-
Par,
Very nice. While I like them both......ya got to know this old man is a sucker for them Mollegabets.....very, very nice. Curious to know if you find the same attributes of the design as I do (and others), namely light in the hand, good speed and cast with very little to no hand shock and quiet? I've also found them to be very tolerant of miss-matched arrows. Again, I like ;D

Thank you!
I like mollegabets too, for a while, every time I draw out a bow on a stave, it somehow became a mollegabet. It just seems like a very good design, as you said: good cast, light, quiet and small hand shock. But to be honest, I haven´t build that many different type of bows, so it´s hard for me to say what I like best.

Nice work and bookmarked each for April Self BOM fun, too.
