Just been outside shooting my ACS and here is what I believe.

1. My draw length is what it is for today.

2. Spine is irrelevant if your releases are dead clean and active. I am shooting 500 spine arrows at 30 inches with 125 grain points and 250 spine arrows at 30.5 inches with 180 grain glue ins and they are flying fine and going where I want them to (when I do everything right).

3. If you are not doing everything right form wise then draw length, draw weight and arrow spine are irrelevant.

I build all my bows measuring draw weight and length from the throat of the nock to the front of the riser. It may be "wrong", but Im consistently wrong that way!

It won't be wrong if your riser is 1 3/4" from throat of grip to front of riser...  :D

So what is the AMO standard for self bows, anyway?

Don't think there is one....

there are none, never could be any.

amo is all about setting business standards and has nothing to do with the real world.  make life both easy and sensible, use the front of the arrow shelf, at the back of the bow, for all bow draw length considerations ... include non-selfbows, too.

i was asking since i was going to try and find the actual wieght at 28" because a possible buyer of my bow wanted to know if it hit its wieght. after spending a little time shooting it with my new arrow i just made up (thanks for that vid and all the advice rob) its shooting bare shafts and fletched arrows right together at 20 yds. bows off the market.

anyways thanks for the help guys. deffinatly going to order a digital scale soon

.....draw lenght is measured to the back of any said bow - case closed ! Just like Rob stated in his first post on this thread .... anything else wouldn't be standard .   :D

Quote... anyhow,I recently purchased an Easton digital and have found some unusual results. I think out of 10 bows tested only 2 were on the marked weight from the Bowyer. Alot of the bows appear to be about 2 lbs heavy. I actually found one bow to be 5 lbs heavy. It is very interesting. Actually thought maybe the scale was off being several bows came in 2-lbs heavy."

all of this is the norm, not the exception.  to have a standard for measuring precise bow weights requires a standard, calibrated tool that all bowyers use.  

in the long run, a few pounds more or less isn't the end of the world, though it may be a disappointment of sorts.

then again, how was the bow weight measured?  what kind of calibrated scale was used?

I concur Rob. I measured the arrow from the valley and marked the arrow at different lengths. I used the card with a hole in it method. Seems to get things pretty close.
