Don’t ask how long it took to figure this out!! All started by trying to figure out if my tiller needs fine tuning - so please feel free to chime in!
I saw someone else had posted a GIF - so I thought I would give it a go!
I took a slow-mo video on my phone and then used the free App GIPHY to turn it into a GIF. There is a share tab - which says “Copy Link” and if you paste it here like a picture - voila!

Pretty neat Tommy.Nice bow.Sometime I'd like Robin to do that for me.Looks like the timing of your limbs slamming home is pretty good.

The harmonics are pretty fascinating ... here’s another one! Getting better at this. I think I am going to stop tweaking or I’ll loose too much weight. I’ve thinned the tips and not feeling the hand shock anymore. You can really see why a heavier arrow absorbs more energy from a bow...

I think it'd also be helpful to see a "before" video, showing the limbs' motion from brace back to full draw.

Be great help for limb timing and effects of positive or negative tiller on performance and longevity.
Can see why selfbows just don't stay the same over time and thousands of shots.
Make one shooting three under!!!
Can see the arrow paradox very well in second GIF. Why its so important to get arrow pass just right and how a good heavy arrow will save your bow harmful vibration over time.

Awesome video. Your arrow is creeping forward before your release. Good video for working on form as well as watching the bow react. and when the arrow leaves the string.

It looks like you might be nocked high with your arrow on the string and the handle does move noticeably when string slams home.
Does the arrow porpoise any when flying? or stick in target nocked end up?
Shooting really light weight arrows over time in context to it's draw weight is not good for most any bow.

So Bassman - just to clarify - my normal draw length that I shoot comfortably with is 27”! I am pulling to 29-30 there - hence the creep. It is a bow for a friend. He gave me a bunch of spearfishing gear so returning a favour. To BowEd - I have two arrows spined at 74# and 31 inches long and if I pull to the bows full(ish) draw the fly like absolute darts. The difference though in performance between a 27 and a 30 inch is incredible. I really hope my buddy draws as long as he says! The arrows are 600 grains. Bow has about 1.5 inches of “backset” unbraced. I do think you are right about the nock point. I haven’t put a nock on yet. So was guessing. But a few shots felt sweet and a few didn’t. Hard to tune someone else’s bow. I will leave Rich to tweak it I think.
I would have shown the bow from brace more but there is a limit to how long a video can be to turned into a GIF. I can do another though. It’s actually really easy now I know how! Thanks for all the comments.

Well done! Wish I had your photography ability’s. Arvin

Sounds like your bow held up good.I'm sure there's a big jump in fps speed from 27" to 30".There is from 25" to 28" here too.A good 15 to 20 fps.
