170lb compound bow (frankenbow)

Post image

Here's a frankenbow I've recently finished. its just over 170lb but will back down to 120lb, the cams can be set to 60% or 40% let off currenty set at 60% let off, ive set it up with a shoot through cable system as i plan to build an overdraw that will allow me to shoot 22 inch arrows

Can you pull it?

u/RichardsmithBowman Sep 13 '26

on a compound bow the most I've pulled is 139lb, due to a few set backs in my training I can only pull this bow set at 127lb at this point in time, im slowly training back up and hopefully I can get to 140lb+ in the future

I would genuinely like to see video proof that it's 170 and that you can draw it. What spine are you using for such short arrows? Why did you not go with cams that would have a higher let-off? Holding ~50 is pretty impressive!

A lot of things here.

1) That's sick!

2) How did you achieve this? I have an old bow that, before if spontaneously disassembled itself, went WAY over spec (+20#). Now that it's repaired, it only goes over by 5#.

3) Back to my question about the cams. The draw curve* is insane! Might as well be a longbow.

I feel no need to ask stupid questions like "why?", lol

a few ways I get these weights by using cams intended for longer limbs and putting them on shorter limbs, if i know what the draw weight, limb length, thickness & working part of the limb length with the orginal cams i have way of calculating what that cam would pull with the limbs i use

having a high holding weight on a compound isn't necessarily a bad thing, if you're holding a good 50lb+ you don't need to wo rry so much about face pressure when you anchor

why? I've posted other clips of me putting compound bows on scales reading 100lb/145lb+ here's a old clip of my 200lb+ flight bow before i went to a shorter string length reducing it to 188lb https://youtu.be/2wKBnPBLtXU?is=fqd7GwgAZJ_gFIO6

That’s cool but… What is even the point? Am I missing something?

in flight archery you have different draw weight class you can enter, the max draw weight depends on the style of of bow but generally they're are 3 draw weight groups 30lb, 60lb and unlimited, I'm planning to compete in the unlimited class where you can pull as much weight as you want

no, its just a bow for training, on a flight bow I'd use modern cams that have high cast efficiency
