I'll push a couple of my tree limbs through the chrony with it after while (let it cool off a little first, my fat rear no likey heat) They weigh around 600 total. Let you know what the speeds are. While I'm doing that, see if you know where I can find about 40 blanks to make some new trad. arrows ifn ya would please. Like I said, I have the last few I had hanging for final straightening and turning.
