Progress- still working that stiffer limb but getting better. The help here is invaluable.

Don't pull it that far!
Sort out the limbs strength relative to each other.
You still have the same problems as mentioned above.

You need a tillering gizmo! Make one before it is too late, don't take any more wood off your left limb.

All the drawing packages and stuff only really help if you know what you are looking at... I've seen plenty of random ellipses draw on pictures to "show" the tiller is good. You need to get your eye accustomed to seeing the curve, an app etc is no substitute... IMO the best aid is probably video of it being flexed. The curve drawing rarely shows something I can't see already but is handy for showing it to someone else who probably couldn't draw the curves right themselves!

That simple gizmo makes a huge difference. I built one this morning and it's totally different tillering with or without it. Also drilled some holes in my tillering tree for a peg to hold at different draw lengths. HUGE help!
