New bow hanger

[Jeremy K]

Got the idea to build some ultra light weight bow hangers . For awhile ive been wanting to get a 3d printer ,from there i wanted to use it to mold custom carbon fiber . Part of the reason for this project was to start to learn about the bonding procedures for carbon fiber . For the first one i purchased the tube ends so i could see how much clearance they use from the aluminum to the tubing for epoxy . By doing so i learned the ends are also slotted to allow for thermal expansion and not fatigue the epoxy . A few pictures of the build and the total weight is at 5.3 ounces without the tree screw . I have tubing with half the wall thickness for the next batch , i will be making all the tube ends for that build ,i'm guessing the total weight on those will be 3.5 ounces finished.

Looks amazing! I would think you'd want a deeper hook for the end?

I copied a similar version ive hunted with for a few year ,its plenty wide enough for either your cam or a hole in your riser.

Gotta love the fellow machinist brain at work.nice work!

Nice! Im impressed

Heres the difference between the two tubes ,the larger diameter is the current build and the smaller stuff is for round 2. It's crazy if you've never handled carbon fiber ,it weighs nothing ,you can try as hard as you want on a 8 inch piece but you cant even flex it let alone break it.

Great job JK.......I love it.  

What's the plan for the screw end?  Gotta be a long slow taper with a sharp point.

I dont have access to a lathe that I can cut a tapered thread on so I called in a favor from a fellow tool maker that I've worked with most of my career.

That’ll do!

I’m jealous of you machinists. Not only are you generally creative enough to come up with ideas like this but you have the ability and knowledge to pull it off!
