Unstrung it has very slight RD,  almost straight.   Where should I scrape on this?

Ya got a few hinges there. The fades need to move.

Could be my design or the limb's natural profile also Pearly. No way of telling without an unbraced front and side profile looksee.

This bow had a huge hinge due to a crack on the belly.  It was the bow I received for last year's bow swap and it has sat after a few rounds of shooting and trying to patch the crack.   I hate to leave it there so I'm trying to get under the crack and I have to take a LOT more wood off.  I'm hoping to get 25-35# at 29".  I'll get you some pictures when I get home.

The whole limb has to weaken down until it matches your weakest spot. Get your gizmo crackin'.

Post by: Cuban Missile on April 19, 2012, 04:52:00 PM
I figured I would tiller first and then once the tiller is good I would take off wood till I got under the crack.  What do you think?

Nothing else matters until the tiler is good. The more you bend it now the worse the frets get.

Yeah that worries me too.  Here are some pictures unstrung.

I agree with Roy's assessment as the reflex's at midlimb should be flatter-looking at full draw and everything else curving but instead its all opposite with the reflex curving and stiffness seen outward from there.
If you want a super light bow then great you are on the right track but I would sinew the thing and retiller from there and have a heavier bow in the end.

It has a boo back Steve.

I withdraw my sinew suggestion.

I would like to know how you get that oval in your pic.  I have CS5 but have no idea how to get a perfect oval like that.  It really helps you see the tiller of the bow.  I would like to try it.

John, the oval is really easy to do in MSPaint, comes with Windows. All you need to do is grab the oval shape from the box of shapes and click a spot on the tip of the bow, drag to other tip, then drag up or down to get the oval curve you need.  You can grab and move the finished oval to better line up on the bow limbs.  It only takes a few tries to get it right regularly.
You just need to make sure your pic is level.

LOL Briarjumper... Photoshop is tooooo powerful for just a simple circle!  For all those MAC users you can download paint brush to do it.

Cuban, Looks like some scrapping in those areas Roy marked should get you a good looking bow. I just hope you don't loose too much weight in the process.
Title: Re: Tiller advise
Post by: Cuban Missile on April 20, 2012, 03:25:00 PM
Yeah me too... If I do loose to much I have a couple of lams of Maple. Would that work for the belly or would that be too week in compression?
Title: Re: Tiller advise
Post by: PEARL DRUMS on April 21, 2012, 07:39:00 AM
I would use osage lam's, or Ipe.
Title: Re: Tiller advise
Post by: Pat B on April 21, 2012, 08:57:00 AM
I would work on the stiff outter sections of the limbs first. A few scrapes on each should get those areas bending better. After that work back to or into the fades.
 Adding a belly lam will get your weight back up but like Pearlie I would use osage, ipe or another strong in compression wood.

I was able to work the tiller out a little better.  I still have a little hinge on the right limb, but now there is a splinter on the back.  It looks like it was hit when it was cut.  I fear it is the end of this bow what do you think?

Wrap it with silk thread and glue. It should be fine. Your tiller is mucho' better. The fades are a touch hard yet.
Title: Re: Tiller advise
Post by: Cuban Missile on April 23, 2012, 04:02:00 PM
So my plan is to soak that splinter with CA and then touch up my tiller and then bring the weight down before wrapping.  If all goes well I'll post pics of the final product soon.

That trick with the Microsoft Paint 'oval' is too cool, I picked up a very valuble tool today!  I went back and found a picture of my first tiller and now I can see what was a contributing factor to her blowing up.  Can't wait to compare this 'oval tiller checker' with what the tillering gizmo is telling me on my next tiller.

Yeah the Oval + the Gizmo makes for easy tillering.  

Earlier today I glued the splinter with CA and took off all of the finish and darkened up the boo a bit with ebony stain.  When I get home I'll drop some of the weight and then wrap up the limb with Silk.

Ok down to 40# @ 28" (Sorry for the crooked picture), but I have the tiller to where I want even it and the splinter has been taken care of for now.  I'm going to wrap it up today with Nylon thread, maybe serving cause I can't find silk thread.

Post by: Cuban Missile on April 27, 2012, 09:10:00 AM
Ok so yesterday In the morning I wrapped and glued serving on both limbs.  When I got off work around 5 I shot about 50 arrows and I must say it shoots pretty good.   I kept the weight at 40# @28".  It shoots nice and smooth.  No shock on it at all.  After shooting I put on three coats of Tung oil.  Today I'll put on The rest and take some pictures.

Now its a tillered bow. You can always add belly lam's if you decide to make a heavier bow.

I think I will leave it where it is for know  its 45 # @ 29"  and perfect for squirrels.   I have put at least 500 arrows through her with no problems!

Ok here it is after I shot a carp.  This is my first ever skin of any kind on a bow.  I have to say that carp skin pretty much turns into a fiberglass laminate.  That stuff is SUPER tuff!  Alan last year you gave me more than a bow.  It was a fun project too!
