Title: selfbow bowyers, need opinion on this tiller?
Post by: Tajue17 on March 08, 2007, 01:45:00 PM
i have this bow here and to me the top limb looks a little stiff at brace.  I cannot shoot this right now cause of the 50 mile an hour winds and below zero temps out side and right now I cannot have someone check it from the side at full draw.  

for now though whats your opinion based on what you see?  top limb is pointed left and brace is about 5 3/4".

the brace looks fine except for the waves about a third up from the fades.  they can throw off the way a tiller will look.  it will be hard to say for sure until you get a full draw pic.

To me the outer third of the left limb looks a little stiff.

Looks pretty good so far, but as Cade said it would be good to see a drawn or partially drawn pic on a tiller stick or tree. Matt

looks pretty good to me. You could always try drawing the outline and flipping it around to compare...Terry

Upper limb is a little flat right out of the fade and just above the dip at midlimb.Lower limb looks good but check it after any adjustments on the upper.Has the bow been shot in?

I agree with PV, the upper limb looks a little stiff/stronger then the lower one.

I agree with Jawge and PV. It looks good, but the top limb could bend a little more just out of the fade.

you're almost there.  the bottom limb looks to have a stiff spot just past midlimb.  the top needs a little more scraping just past the fade and past midlimb.

this is making me nervous if from what you see how much more wood you think needs to come off in those areas to get this to start bend,,  (ex;30 passes on the tip of the top limb and 12 passes for the bottom--> as an basic rough example) and do you have a break period with tillering or just keep going non-stop till it bends?

I'm wondering at this point if this will go to one of them back and fourth things and then I've lost 15pounds in draw weight?

Actually,I agree with 4runr and Mechslasher.The outer 1/3 needs to be worked a little.Maybe 20 scrapes and 10 scrapes near the fades.Exercise the limbs a while and check again.I wouldn't touch the bottom limb.

Depending on the poundage you are going for and where you are at,at the moment.There is also another train of thought: you can shorten the lower limb to stiffen it.Which will also increase your poundage if you are trying to play catch up.

Either way,make sure you continue to exercise.

Small adjustments are the name of the game. Like Linc said exercise a bunch after you scrape.

The thing that makes  it  hard  is  that we  don't  know  what  the  stave looked like when  you started.

I  assume those kinks  are just  naturally snakey spots  in the stave.

But was  the stave otherwise uniform,  or  were  there reflexed  or  deflexed sections?

Unless  the stave  was  straight,  while  the tips should  move evenly,  the bow  should not  have a uniform  curve. If  the stave  was snakey  and  has  a uniform curve, some wood  is stressed more  than  other.
