I work the bow slowly down the tree, an inch or two at a time for 30 pulls, correcting what need be along the way. I want the rope to come straight down the line. If it drifts to the left or right, that means one limb is stronger than the other. The rope will drift towards the stronger limb. I begin removing wood a little at a time from the strong limb, and I use the gizmo tool in conjunction with the tree.
ANYTIME I remove wood from a limb, I put the bow back on the tree and work it 30 times to however far I just worked it before. I get the limbs bending evenly within only 3 or 4 inches down the tree on a short/long string.
And remember this, Cameron.. You can always take more wood off, "BUT" once you remove too much wood, You CAN'T ever put it back on. SO go slow and have a plan/goal in mind of why and where you are removing wood.
