Sam, I love your site and videos. Thank you so much for all you do, truly. Your humor and information along with crafty advice make me want to complete every project on your page. Again, thank you. Your great.
this gives a far better arrow match than the Easton arrows chart going on their chart the arrows were all over the place with my measured arrows I'm getting tight groups every time.
Why not just fill a plastic water bottling till it weighs 2lbs? Drill hole in the cap for a hook. Mark the bottle for next time. No poisoning no danger. Easy material list. I dig your videos.
been wanting to do something like this, since I had received a new Mathews apex 8 compound, to replace my Older Martin Scepter II. since it would shoot faster and is a higher poundage. the Shop recommended Victory V3's 400 spine. however when shooting (fingers) the 3 yard-bare shaft paper test (with a stiffened plunger) I got 5" tear right (overly weak) strange, I thought, because when shooting my X7's 2213's I got a near perfect vertical hole ( slight nok low). The Victory's are supposed to be stiffer(.400) against the X7's (.458). but I had thought the test was done on a 29" arrow, with the support arms spaced at 28". did they change the method?
I think there's a different standard for people who shoot aluminum or carbon arrows with a compound or any kind of mechanical release. Instead of using a 2 lbs weight with the rests 26" apart, you'd use a 1.96 lbs weight with the rests 28" apart. But you might want to google around to make sure.
I'm thinking of setting up a chart behind the arrow with marks in 1/16" thru 1" increments, this initial chart will be done with a caliper and would be different for each diameter sized arrow but would be faster than messing with the caliper every time. I made a similar spine tester like you have, thanks for the vid-
Oh ok, Im in australia and we use metric but all the archery equipment is in imperial, like 5/16 11/32 etc and its difficult to find out what size i should buy. Thanks anyway.
I don't know, but if you do a google search for "stu's calculator," there's a spreadsheet where you enter all the info about your bow and your arrow, and it will estimate the spine you need. But the best way to find the spine you need is to get something close, shoot it, and see how it flies. You might also want to do a search for "paper tuning" and "bare shaft tuning."
Does your getting a spine of 52# from having measured 1/2 an inch mean that you need a 52# bow to shoot that arrow? Pardon my ignorance, pretty new at this, so what may seem self-explanatory to most is just not for me.
No, static spine is just one variable. The spine you need is also determined by other factors, like whether it's a longbow or a recurve, how close to center the shelf is cut, whether you're using B50 Dacron or some fast flight string, your actual draw length, and the weight of your tip. You can learn more about it by googling dynamic spine. The easiest way to figure out what arrow shoots best out of your bow is to shoot some that all have the same weight tip but with different spines, and see what works with. There are calculators that allow you to input all the variables, and it spits out the correct spine for your bow, but that is really tedious, and it still only gives you an estimate. You won't REALLY know until you experiment.
The nails should be 26" apart regardless of the length of the arrow. All this measures is the flexibility of the shaft. However, when you shoot the bow, the length of the arrow matters, so you have to account for that. A spine tester measures static spine, but dynamic spine is the effective spine of the arrow when it's shot, and that is affected by the length of the arrow and the weight of the tip.
Great job! This made as simple, as it should be. Thanks for your idea!
A handy little tool. The word you were looking for was "plumb" not perpendicular.
I will argue your point that imagination is a pound more than what you say, as the average brain weigh 3 lbs. :D
Great D.I.Y. I love free projects. :)
Love the Arlo Guthrie stuff.... hahaha...
Great Video.
I think every Bowyer in Germany knows an likes your Videos;)
Thank you for your great work:)
Thanks , its help full
Alice's restaurant 😂
Remember Alice's restaurant isn't called Alice restaurant 😂
Great video
;) Ah, yes, but imagination comes from the brain. But I'll have to concede, some imagination weigh more than others. ;)

I LOVE the Alice's Restaurant sequence - inspired
Very nice and simple. No frills. Thank you.
'Alice's Restaurant' ! love it !

26" for wood. All others 28".

Yeah, next folk weighing produce risk accidental lead exposure.
I love musical interlude. LOL, your imagination... Yes your imagination weighs exactly 2 pounds LOL😂🤣
what diameter shaft do you prefer to use
Genius! - and entertaining too. Thanks so much!
nice, no fuss, no muss.
liked the Alice's restaurant monologue too.
+1
Alice's Restaurant 😁
"Your imagination weighs exactly 2pounds" my wife came in to see what I was laughing about 😂classic!!

Hahahahahaha...........Arlo would be pleased with your use of humor in an otherwise dull but informative vid.

That sounds like a capital idea.

Thank you. So what would be the spine number for 29.5 " arrow 100 grain tip
With a 50 pound 60" recurve?

Wow! i really enjoy the video as well the "Alice's Restaurant" bit
camera position friend....camera postion

Probably. I guess it's all relative.
I enjoyed the brief "Alice's Restaurant" bit
will this work with a 29.5" arrow/ what distance do you set the nails?
