Lab Rat, thanks, that one worked. Yes, that is the same Thread. Please note in the Thread that of nuts&bolts and his referencing the Martin manual for timing.
Understand, timing in this Thread was set virtually by the Martin manual and timing is OP's question. Gary was seeking more speed. Understandable is changing the "timing" for a individual and it's no big secret to advance the top cam perhaps 1/2 twist of the cable. Simpler, some us want the top cam to hit a tad bit before the bottom cam. We've been doing this for years with the Hoyt cam&1/2 and I've done this with all 3 of the Martin Shadowcats I've shot and owned - 1 being a loaner from a Martin Staff shooter and 2 being my own.
Note; Gary said something of 3 pounds increase in draw weight and I have found as much as 8 pounds. This equates to about 6 to 24 fps. Changing letoff from 80% to 65% could amount to possibly 10 fps. So anywhere of 16 to 34 fps increase. BUT! If the draw weight is too much for you, then you must back off the limbs and this effects a bit of all that you've done.
If wanting more speed out of a bow, then there other means without increasing draw weight and losing letoff.
wabbit, that was AMO draw length. Mods set in the #3 holes, and the draw difference made up with the string. Might not be the right or best way to do it, but it's worked for me. lol
Ok, I gotcha. Ya last spring I played around with the chrono and everything, and settled on the 2 slot, using the draw stop to set my dl. I tried the 3 slot and didn't like the valley it left me (or lack there of) once I set the draw stop. I was seeing blistering speeds though, about 10-15fps more than I currently enjoy. ;)
Just goes to show you how adjustable these cams are! ;)
It should be possible. My bow has a 72# max draw weight, and I'm only holding back 13.68# at full draw. It just takes lot of playing with the cables and strings to get everything just right. Just make sure you don't go very far (1/8-3/16 inch) from specs for ATA and BH.
wabbit, I was wrong on my DL. I had forgotten that for some reason, a 29 DL felt best for me on the Onzas. I have no reason for this. Same anchor point, same "grip", same everything. It just feels better at 29 with the Onzas. That's AMO. Everything else I have is shorter.
