Something finally learned about Tillering...

[Bowjunkie]

I hope to do more to help clarify and demystify tiller soon. I have demos and experiments planned, a long list of questions to address, test bows and measuring equipment prepared.... what I don't have enough of is time. Need to retire I guess. But the wife says if I retire, she's putting me to work at her bakery so...

[Longcruise]

Difficult choices.  I didn't have a choice on retirement.  A smashed femur was the incentive.   

[Bowjunkie]

Oww geeze. I bet that didn't feel good. Sorry to hear about that. That's sure not how a guy wants to enter retirement.

   Good stuff... Thanks Junkster... 

    I am glad and relieved that I finally had that A-ha moment...  It was the last piece of the puzzle that I was missing...

No reason to go all Oprah about it.

What's Oprah??  Is that like Ocra??

Been using the dynamic method for years., but mine is set up laying on a table with a graph drawn on it . Use a boat winch to draw and place a curved section to imitate finger width on hook of scales and draw back and map limbs. Once the tips arrive at same position its mostly done. Works well

Oprah Winfrey.  She embedded "aha moment" in the American lexicon.

Shredd, Thanks for this post. Gets rid of a few more cobwebs, dang spiders anyhow.

They carved the tree into the walls of the cave:)

Hold on, let me get my boots, It's getting deep in here

I wish I paid more attention to how my dad tillered. He never had anything but a knife and I'm still shooting some of the bows he made 40 years later.

Learn how to floor tiller, when you do this and get good at it, the bow can be close to finished before you ever brace it.
Edit---Then go to the tiller tree.

Look up Clay Hays on You tube, he makes bows without a tree using only a knife. He has numerous videos on making bows.

   He is also on the tv show 'Alone'...  Just saw the first episode last night... He gets a grouse, a fish and a whole slew of mushrooms on the first day or two, like he's shopping at the grocery store...  He may end up taking this thing... There is also a chick on there that is very knowledgeable and will eat anything...  I think they all have tarps for shelter... After making a quick temporary shelter I would think my first priority is food, especially if you are skinny...  Some are going hungry, wasting valuable energy and calories building a permanent shelter first because of the fear of bears...

Water 💧 gotta have Water.

[Shredd]

 Yes indeed... But...  They are all on a lake and have a pot to boil it...

I wouldn't know,  I watched a couple episodes previously and thought that those seasoned outdoors types who were too lonesome and afraid of the bears to stay more than a couple days was kinda dumb.

The final straw was the guy who risked the loss of an arrow shooting a pine squirrel high in a tree.  He hit the squirrel alright but the squirrel coroner would have ruled it an accidental death.

[Shredd]

   Yeah, that would have been cool... But I am sure he has ol' trusty with him and can hit the mark...

   I have not watched tv forever but I am on the computer a good bit...

There are other things that can cause arrow flight to be nock high .. not just tiller. Anything a bowyer does with tiller can be negated by nock point adjustment... for better or worse.
Using only one nock point when shooting 3 under can cause a nock high arrow flight as the arrow slides down the string upon release and then ultimately bounces off the shelf... I'm told that this can also be the case with split shooters, but less likely.
Bare shafting extreme foc arrows at longer distances can cause some nock high readings as well.
Tillering for three under is a farce in a glass bow anyway... I know nothing of self bows. The thought that +- 1/16-1/8" of tillering will have any impact on a shooter willing to nock tune is ridiculous. A shooters string address isn't that accurate.
Number one rule of archery? always blame the equipment!
