    Hi, newbie to the forum here. I've been shooting on and off since I was a kid (34 now) and I'm just getting into tying my own bands...and they pull much harder than purchased bandsets. Any advice on what scales will be frugal, accurate and easy to use?

    Welcome aboard, Sir Mattman!

    Enjoy jour stay on the sun deck!

    Band proportions depend on ammo weight and draw length/ desired
    stretch ratio. My 8,2mm steel balls weigh 2,25 grams; my draw is
    rd 110 cm; I cut bands (Theraband black) 28cm long, tapered from
    rd 20mm to 15mm (durability) or 20 to 13mm, for the punch/speed.
    The resulting "active" bandlength is 25cm, two bands per side.
    (pouch weight is rd. 0,3 grams - kangaroo leather, rd 10 x 70mm)

    The resulting drawweight is rd. 2.5 kg, steelballs start their flight with
    a velocity around 80meters/second - which I find prety comfortable.

    I hope this helps a bit (TBB is rd. 0,375mm thick; TBG rd 0,65mm). Transfered
    to theraband gold I´d give 23mm tapered to 15mm, one per side, a try.


    Hopefully this helps/ is what you expected..

    kind regards,

    Be

    Thank you Bemahoney! I'm looking for a commercially available archery scale. Accurate but not going to break the bank...

    What he said with all that unnecessary math is " Go Big or go home!":D

    I might get a lot of slack for this... but use thera-tube red. Stuff is fast easy to tie into bands, I even use it for target sniping from about 20 meters accurately.

    What do you mean by scales? Something to measure force or the pieces added to the sides/back of weapons.

    If you want to measure draw weight, a cheap luggage or fishing spring scales are perfect.
    Just get one with a smooth hook and a comfortable handle.

    My under $10 digital luggage scale displays the last weight.

    Scales mean a lot of things on this forum.

    Luggage weighing scales are cheap and easily obtained at a lot of stores in the USA.

    I have one like BoyntonStu and test the slingshots with them held in a vice while being pulled through the scale with a come-along.

    Sorry for that math ;) - the word scale is far from weight..

    "wiegen" mean weighing in german, here a scale (I know that word, normally..)
    is a "Waage" hence to scale sth. ("skalieren") means scaling it´s size...

    I apologize for this misunderstanding!!!

    - That luggage scale (5$?) thing is so simple and true that I simply did not
    receive the original question´s meaning...


    I shall be doomed, Super Baba will have to fix me ;)

    kind regards,

    I had the same concern since scales can mean several things.
