I think answers will be all over the place on this. Most that I have asked tiller both limbs the same or zero positive. I still can't get my brain around the why.

I do everything the same EXFEPT while on the tillering trree... I pull on the string from the three-under fulcrum point... instead of from the split-fingered fulcrum point. I have another pulley already positioned for 3 under.

Then just tiller and syncronize the limbs like any other bow, allowing brace height measurements to be whaever they end up being.

Sometimes a three under bow has negative tiller and many of my split finger bows have an even tiller.. sometimes theyre negative too... depends. I make it what it needs to be to maintain limb timing.

Ron, Jery Brumm told me he tillers both limbs the same.

My pulley will pivot so no problem on moving it over some.
Onehair, when pulling on the tree for a,split finger tiller. The hook and pulley line up with where the,arrow,shelf would be.
Or just below. For three finger,under I'll be moving it down towards center about a,finger,width.
