Well, third time seems to be a charm. I got her to my draw weight of 45# at a length of 28" without her blowing up in my face. I think my tiller looks pretty good. Anyone see any problems?

right limb, mid to outer needs some more scrapes
-
You have a bad hinge at mid limb on the right and need to get the first 6" out of the fade working on the left limb.
-
Both fades are also too stiff
-
And I thought I had it down! :)
-
Did you use a tillering gizmo?
-

Well you're definetly getting there very close
-
Do you have a pic of a braced profile. If you look you should have a bit more set in the mid limb on the right. If you monitor the set as you tiller it will tell you if there is a spot that is a little more stressed :). You should think about getting a tillering gizmo. Congrats on getting one not to blow up. Remember it better to have a well tillered bow that is underweight than a heavy bow that is out of tiller. Keep it up you are almost there ;)

Congradulations on your shooter! That's awesome! Go out and enjoy shooting it! Next time take a six inch thin board and run it along the belly. Look at the gap between it and the bow. It should remain pretty much even as you slide it along. If you do this you will see the less than ideal areas of the current bow. But all bows have less than ideal areas. We all strive to make a better more efficient bow next time. Of course the perfect bow never comes. Congradulations, enjoy your bow! Welcome to the addiction, I mean passion. ;)

Thanks guys. I'll work on it some more tomorrow. I can see the spots that need attention now that another set of eyes have pointed them out. As far as tillering, I just used a surform rasp. I guess I'll look into one of those tillering gizmos.

Do you have a scraper? If not you should really get one of those too. It is one of my most used tool. Very easy to make and you will love how they make curls :)
-
Surform rasp is much too aggressive for tillering, I've hinged a bow with it when I was impatient. Use a knife held at a 90 degree angle as a scraper.
-
Good work for a third try - and good advice from the guys.
I cannot see the pics with full draw on tillereing sticks - that takes long seconds to take the pic and that can damage the bow ...
-
Getting close...... A 3" folding knife is all I've used as a scraper like TacFate says. You can even slightly hollow the limb (like Simson does) with the tip or use the flatter edge toward the handle - held 90 degrees to the work.
-
Fades and tips are both too stiff (especially fades). Use that tillering stick to poke your camp fire! Get rid of it! Set yourself up a tiller tree (if you haven't already) with an inline scale, like this:

Tell us what you really think about a tiller stick adb, ???[all opinions] I use a tiller stick and is very useful to get one to brace,then move on to the tree.I never use one for full draw. :) Not bad for a 3rd for sure but as other have already said /stiff fads/stiff outer,to much in the middle,it will come with time and become much easier for you to see.The gismo is a great help or a short straight edge 4 to 6 inches long to run along the belly to see where it needs to bend, especially on a clean fairy straight piece of wood, just keep the gap even between belly and straight edge,or take wood off where the pencil makes are if using the Gismo,the kinky twisted stuff you almost have to do by eye. A scrapper or knife for final tillering is also very helpful to use so you don't take to much at once. ;) :) :)

lol...we dont ALL have accomidations for a tree...stick is fine...for now...lol
-
Well I built myself a gizmo last night, and I guess I'll take a knife to it. Maybe I'll use sandpaper instead.
-
If you fix the tiller on that bow now you will be down to about 25# when finished. If the bow shoots good I would shoot it as is and make another in the meantime. How much set did it take mid limb?

Hey, Pap... you could probably also use that tiller stick thingy to kill a snake if you had to! 8)
-
Gizmo will show you the bend for sure...The draw back on it is you have to leave your bow in a full draw position for some time. It's good for beginning stages but is risky for braced full draw :o
-
gizmo is a great tool, only takes a second or two to check your tiller with it, I use a tiller stick out to 20" that's as far as I go I usually shoot them in from there
-
Yeah I use to do that a lot. Just try making mid limb and the tips the same thickness and remove more out towards the handle till its a little thicker than mid-limb. Great bow though for your third attempt. You will get It, I know its tough to always have your tiller shot down. I always hated getting tillering advice ;D
Absolutely, if you can do it, set up a tillering jig. It really helps get a great tiller?
-
Thanks for all of the help guys. I went back at it this morning, and it does look a little better, but my weight is down to about 35 pounds now so I'm going to finish it up. I shot it about 20 times today and it's not real fast, but I was also shooting an aluminum arrow so it might have been a little heavy. Either way, I'm going to put some finish on it and take the lessons learned to an new bow that I start tonight. I gotta tell you, the feeling I got from shooting a bow I made with my own hands was more than amazing. Once again, thanks for all of the help. I'll post a picture of it when it's all finished up.
-
Congratulations!
You got good advice about getting the near handle wood moving and throwing the t stick in the fire. LOL. Rope and pulleys are great.
Mark a nice heavy pencil line where you want the bending to start which is usually the end of the fades.
You can leave it strung. Take 20 or so scrapes, 20 short draws, and check tiller.
I've spent hours in that area.

Glad you got a shooter,that is always a good thing, Man this is jump on tiller stick
day,snake killer/fire wood ;) :) I have only built a few hundred and involved in a few thousand so I may need to reevaluate my way of doing things ??? and see if I can start doing it the right way, :-\ Or it may be as has been said many times,we all know how opinions are and everyone has one. :) Believe me either technique will work just fine if use properly. ;) :) :) :) Again congrats on a shooter and if you are like me when I started ,can't wait to start the next and see if I can apply what I learned. ;) :)

+1 Pappy. Tiller stick for me. Never even had a tree till I built one last weekend. Glad I have it now, but have built all my bows without one. A useful tool, but it wont replace my use of the tiller stick. Many ways to get to the finish line. It's those danged computer circles I want to trash! :)
-
;) ;D ;D ;D I love this place. :)

Pappy, no one has said anyone was doing anything wrong.
Yup, t sticks are fine. Use what you want. Life is all about decisions.
I've made about the same # of bows as you. All but 6 or so on a t tree...rope and pulley.
I'm prejudiced against mine or at least I was. I burned it when it exploded having the bow conk me on the head. I have to admit sticking that son in the fire about made my day.
I've had a few bows go on the tree. I can just imagine the damage they would have caused my face and head if I was using a t stick.
I fought many battles with my chem students getting t put on their safety glasses. Gave a zero or 2 over safety. But now that I am retired I've mellowed.
It's all about free will.
It took a hard hit to set me straight. I would not wish that on anyone. :)
On a side not, I remember my mentor cautioning me against the use of the t stick.
When I told him what happened. He just smiled.:)
And so...:)

I hear ya Jawges,no offence taken here,never had one blow on the stick but as I have said many times,I just use it until it braced.

Well, that sounds pretty safe, my friend. Thanks for clarifying. :) Jawge
