I made one similar to this by Boo's instructions. I used a scale to see how tight the string will stretch, mine will stretch to 500 pounds if needed. I marked the bolt to show when I'm tightened into the 300 pound range.

Where did you buy your hook bolts from ? I get mine from the local Home Depot but those will start bending at around 400 pounds.

I ordered hardened steel from Ace and it took a few weeks to get them delivered. The hooks that I bought are rated to 2500 pounds. I also added a engine compression spring to the bolt that I tighten the string jig with. I knew regular hooks would bend Marty.

Yes, using that spring helps tremendously with distributing the load placed on the hook bolts very well. You definitely need those hardened steel bolts. I havnt bent a bolt since I upgraded my system.

I only reserve my Flemish strings for my Excalibur bows. Just a hobby for me. I don't do it for anyone else. I'm not that confident. Lol

It helps to keep the threads oiled also.

@Stack:

Looking good. Maybe you can do a photo from the side, so that I can see the hole and fixing point of your hooks? Thanks

Apparently, it helps to have a can of your favorite brew too!

That can contains the "thread" lube Marty mentioned. :LOL:

Marty, take your hook and beat the first bend until it is straight as in the letter J as opposed to them being in the shape of a question mark.
My design does not allow for constant tension due to the lack of flex in a 2X4. To alleviate this, install a washer, then a die spring, then a washer. Instead of a nut, use a threaded rod joiner which is essentially a super long nut. Also use MoS2 on the threads. It is far better than oil, grease or any kind of anti seize.

There’s a whole lot of frustration in not knowing so I figure I might as well show you guys the reshaping of the hook as well and how I extend the hooks for shorter strings and cables.

I've got my system hooked up pretty good now Boo, thanks. I could've used that when I first started a couple years ago when I was using the BCY Micro string stretcher and I was bending hook bolts on a weekly basis. Since I've upgraded, I don't have this problem anymore. I can see how by straightening that bolt out would disperse the load better.
