Another question since I am using a 16 Strand string for tillering. Should I use a stronger string for 80+#?
--- End quote ---
That's fine for a Tillering string... most force on a bowstring is when the limbs slam home at the end of ashot... which doensn't happen with a tillering string.

William M.:
Thanks!
Still feeling anxious tillering it since the last one exploded :-\
Gonna aim for 80#, with a nice tiller to have at least one success feeling ;D
Gonna try to use a 16-18 strand B50 string
William M.:
Been tillering for the last couple of hours, bending till brace hight now at around 100#.
Can I low brace it with a 16 strand too? Or should I use a 18 strand?
willie:
you are aiming for 80# finished weight? your choice of final draw weight should not exceed whats possible based on the dimensions of your stave. your 36 mm dimension stated earlier may well be ok for the proposed 80#, but not for more. I don't know myself, as I do not know much about the ash you are using.
during tillering, a lot of guys make it a point to never pull over intended finished weight. this advice is especially prudent for beginning bowyers.
even when you reduce some more so that 80# gets the bow to brace height, that does not mean it is time to brace. early bracing often causes a bow to be overstressed. at that point, you might try to shorten the string to the "as short as possible condition" until the tips are brought back to 8 inches or so (pulling 80# of course), then up date your video. we like pics :)
now is a good time to trace an outline of the back of your rested stave. it will be useful later to compare with if the bow takes some set in the later stages of tillering.
William M.:
Thank you very much willie! I was getting "overmotivated ;D Yes I should stay at the 80# max. as planned.
Here are some pictures from today and a video tillering. This is after heattreating the belly. I was slowly taking more and more away, but still in small steps. Maybe I gonna finish tillering in a month or so haha

On the left side itīs uneven, first I thought itīs a knot but it isnīt. It seems thick from this side but on the other side its thinner because it has a light twist on this limb. Not quite sure if itīs a weak point or not.
