Title: Tillering help
Post by: grinner on April 09, 2012, 08:38:11 pm
Hi, I am tillering my first bow and I just wanted to get someone else's opinion before I pull it back farther than I should. Do I need to take more off near the handle to get it bending more. Also anything else I need to change?
Thanks for all the help (http://i1124.photobucket.com/albums/l578/shawnbu1/DSCF2291.jpg)

What is the draw weight at this point?
Title: Re: Tillering help
Post by: grinner on April 09, 2012, 08:48:06 pm
Probably 10-15 it is on a very lose string still.

 ;) Can't really tell much at this point, but i would pull it back a bit more to get a better idea how how's tillering.

Does not look bad.....just remember don't go past your intended draw weight.....and remember to exercise it real good.

Post by: grinner on April 09, 2012, 11:02:28 pm
OK I have been exercising them good. Where is a good place to buy a scale? THanks

any stores that sell fishing gear usually carry fairly decent pull scales.... you can get a 50 lb or 100 lb one

Walmart sells luggage scales that go to 70# for about $10

I think it looks fantastic at this point.  Keep doing what your doing, one inch at a time, and don't pull more than your target draw weight and you will have one sweet bow.  :)  Good job!

It's hard to say - a long string like that tends to under report bend in the outer limbs. I'm guessing that if you put a short string on it now, it would be a bit whip tillered.

I'm with Gordon,I only do long string with a string long enough to reach tip to tip.
Seems to be bending pretty even tho. :) I try and get mine to low brace as soon as I can. :)

What Pappy and Gordon said I go to the short string as soon as I can. Ron

I think from the end of your handle area out to around 7" or so is gonna be stiff n needs some scrapes on both limbs judging by the lenght of the long string your using,and by the looks of your thickness taper in that area
Title: Re: Tillering help
Post by: Eric Krewson on April 10, 2012, 11:11:21 am
The left limb is way too stiff from the handle out about a foot or a little more. If you go to the short string now you will almost have a hinge past just past the stiff section. The right limb isn't too bad but does need the inner third scraped on a little bit.

Put a gizmo on those limbs, it will tell you where to scrape.

DId a little more tillering today. This is on a tight string now. Hows it look? THanks(http://i1124.photobucket.com/albums/l578/shawnbu1/DSCF2298.jpg)

Yep still lookin darn good to me.  Keep us posted on the draw length and weight.  Bend that puppy more!   >:D  ;)

Looking real good. Looks like you got yourself a scale also. You're going to have to move your lower pulley down a bit more or your scale's going to hit it before you get much of a draw.
Title: Re: Tillering help
Post by: Pappy on April 12, 2012, 08:55:37 am
Looking good,keep on keeping on, Maybe a little stiff at the fads at this poing but I usually save them toward the last,if you get them bending there to early you will
get set and set there really shows up with string follow. Won't be long you will need to get it to a low brace,that will give you a better look. :)

Yeah I bought a 70 pound butcher scale. I am at 30 pounds and 13 in draw with the string just touching the handle when its strung up. how many pounds will it put on a inch? It is a 72 inch bow. Thanks for all the comments
Title: Re: Tillering help
Post by: Pappy on April 12, 2012, 10:47:10 am
Probably 2 1/2 to 3 more or less a little.

In my experience Pappy is right on.  I usually calculate it at 2.5 pounds per inch and target hitting my draw weight at 1 inch short of my target draw length.  The bow always looses a few more pounds as you shoot it in, sand it, and the wood settles.  So now you are at 65# @ 27 inches for example.

Here is another pic of my tiller. Is it just me or does the left limb bend more mid limb than the right? Thanks for the help

Post by: PAHunter on April 15, 2012, 12:54:46 am
still lookin good to me.  How many inches and pounds are u at?  And what is your target draw length and pounds?  I'd pull it another inch and check it from there.  BTW draw it 30-50 times to a given inch before progressing.  It trains the wood and can change the tiller slightly at times. 
Title: Re: Tillering help
Post by: grinner on April 15, 2012, 01:05:56 am
Yeah thank i worked on it for 8 hours today. I definetly drawed it over 50 times per inch i was being really careful. I got it down to 50 pounds at 28 inches how does my tiller look here. Do i need to change anything before i shape my handle and shoot it some? Also what should the brace height be to the back of the bow.

Post by: PAHunter on April 15, 2012, 04:06:05 am
50@28 - sweet!  Keep in mind final shooting, sanding, and puttin on tru oil (or whatever) will steal a few of those pounds.  You will still have a very nice killer though!!   :laugh:  Fire at least 100 arrows through that puppy and leave it braced for an hour or two; then have at it with increasingly finer grits of sand paper.  Round the edges well.  Your kicking butt, keep us posted! ;)  I suggest looking at many handle exmples and take your time with one you like.  Here one style that I've done and like for example.

Thanks for the help. I plan on trying to get my grip and self shaped today. And am fine with it dropping a few pounds. thanks

Post by: hedgeapple on April 15, 2012, 06:12:02 pm
This is probably a stupid question, but the string looks long to me.  Have you braced this bow, yet, like with the sting 4 to 6 inches off the above the handel?

That bow has only one fault. It's perfect. Other than that, it's perfect.

Post by: grinner on April 19, 2012, 11:54:10 pm
Well i shot it a few time and then but it on the tree and exercised it real good. And the tiller was still looking good to me then SNAP it broke. But i plan on trying again it is addicting.

That sucks, man. At least you had some fun and got good practice. The more you build the better they get.  ;D

Post by: PAHunter on April 20, 2012, 01:54:45 am
 >:( >:( :(  Dagnabbit!!  If you ain't breakin bows you ain't makin bows bro.  That does suck.  Was this a board bow?  If so, how good was the gain?  I back all my board bows now, and they still sometimes break.  It was a good learning experience and that is bar far the most important thing.  Can't wait to see your next attempt!
Title: Re: Tillering help
Post by: Gordon on April 20, 2012, 02:38:02 am
Did it break at about 10" from the tip on the left side?
