This Mollegabet might live
« on: July 07, 2014, 03:44:27 pm »
Well this is my 4th attempt at a red oak Mollegabet and I just might have it this time. What do think?

Red Oak 66" NTN

Dimensions:

12" static limb (not including fades) 3/4" to 1/2" taper in both directions. since my nocks are 1" from the tip, does this make my static limb 11" now?

16" working limb (not including fades) width taper of 2 1/2" to 2 1/4", thickness taper of 1/2" to 3/8" This is not linear, the first third of the limb goes from 1/2" to 7/16", then the last 2/3 goes from 7/16" to 3/8". With these thickness tapers is my limb working unevenly?

2" fades
4.5" handle

currently Pulling 47# @ 22ish"

Here we are at 24" on the tree


24ish inch draw


Here is what the Gizmo says

Left/bottom limb


Right/top limb


My gizmo is only about 4", when in the tillering process should I stop using it?

your right outer limb is a bit stiff. use the gizmo all the way through if you need to, no shame in wanting a perfect tiller.

I think both outer limbs are a touch stiff. Make sure you get those levers reduced right down to where they almost bend on you ;)

Might as well make them short, save some wood to keep warm.

I would round off all those square edges like a small pea before proceeding if I were you.
Some like motorboats,I like kayaks,some like guns,I like bows,but not the wheelie type.

Thanx for the feedback! I will round the edges and then work on the outer limbs this week.

I shot 2 arrows with a short draw and the string shock was terrible. The string was vibrating long after the arrow was in the target. I have a ways to go with the levers.

Yep, those levers have to be tiny. Narrow them before you take away from the belly/thickness, and remember they can taper in thickness from fade to tip. You aught to be able to use it as a one-off spear if the bear comes in for close quarters ;) >:D

Or I guess two-off, since you have two levers...

I've got it down to 27.5" on the tree, but still chasing the outer limb stiffness. It seemed to reappear every time I move down the tree.



My outer limb thickness is a little less than 3/8" and I'm losing draw weight faster now. The brace height got bigger too. I'm almost there though  :)

I already cut out the next one, it'll be hickory this time ;D

The right limb looks damn near perfect, the left still just a touch stiff in the outer third. Sure is fun tillering small working limbs, eh? ;) ;D

Tiller looks good.  If you put the left limb as the lower then you are good to go

Hey yeah, Marc's right, that could be your positive tiller.

Keep us updated on that hickory you mentioned ;)

Tillered to 28.5" with the left limb on the bottom. Drawing 44# at 28".



I might have gone a little to far taking wood off the static limbs though. There was some bend in the static limbs when on the tillering tree, but it doesn't look like much in the full draw pic.







There is still a little string vibration, but not much. No where near what it was before static limb reduction ;)

After I finish the riser, I'm considering using a nylon/cotton camo fabric as a backing. Will this negatively effect the performance?

Is that a string groove cut into the BACK of the bow?  :o That's a big no-no! Unless you glue on tip overlays. It's a serious weakening of the bow, especially with a ring porous wood like oak. I would strongly advice you to file that groove flat, glue a tip overlay on, and re-file the string grooves.

Short answer: yes, it will.
Longer answer: a fabric is typically dead weight. It may add a little bit of security in the sense that is keeps small splinters down. But since the bow is already shooting, there is no reason to suspect splinters will be raising. Since a fabric backing does not 'work', it only adds mass to the bow limbs, which will slow down the bow in principle. The question: how much? And will that bother you? You'll loose maybe a few FPS, which is nothing terrible if it is just a hunting or target bow. I can imagine that the beauty or camouflage added by the fabric backing, outweighs the loss of a few FPS. Other than loss of speed, there would be no real drawbacks.

You've made a nicely tillered mollie there! You can be proud of this one!
