Bear hunt blade

[DIY_guy]

Im making a new set of single bevel broadheads the upcoming WI bear hunt. The main blade will be made from a 7 1/4" circular saw blade and aluminum broadhead adapters. Since they are aluminum I can use a micro saw and a Dremmel tool to cut the slots.









Then it was back to the saw blade





Beveling made easy with the right tool for the job. I get to use my own “Stay Sharp” product to accomplish the task. Here is a beveling video.

I will use J.B. Weld in the slot cut in the adapter to fuse the blade and I will peen over the tip of the adapter in the hole in the blade to further trap the blade on the adapter. The J.B. Weld and eventual paint will have the final broadhead around 180 grains. Here is a video of the fit up before fusing the parts.

The first head is fused to the threaded adapter with J.B. Weld and by peening the tip closed in the hole in the blade. Then it was primed and painted.

In the universe of possible colors for broadheads, Ive always felt that glossy plum has been under-utilized. I hope to rectify that. Who knows, it might catch on. I took an indoor and an outdoor photo and you would think they were two different broadheads based on how the colors seem to have changed based on the lighting.



I calculated exactly just how much J.B. Weld and how much purple paint would be needed to get the head to exactly 180 grains....................... Nah, I just got lucky. The goal was 180 grains but I didn't think I would hit it spot on. Its better to be lucky than good. Now I just need to make a few more.

Thanks for the post. You are quite good. i could never do that.

Those look good. Are you going to shoot a couple to ensure they fly straight?

 

[DIY_guy]

Most certainly. The joy is in the shooting and tuning. These will be used with a homemade longbow.

Wow. That is impressive. I am a do-it-yourself kind of guy but have never made my own broad heads.
Bears can see color and blue stands out for deer so I would pick a 'forest' color that matches the camo you will be wearing.
I might also consider rounding the tip a little so it will not bend if it contacts a bone. A lot of the cut-on-contact broad-heads have made this modification after a few years.
Really impressed. Nice work.

Well done, sir!

Holy guacamole!

First off - the work is damn fine.

More impressive? Your resourcefulness!



"Damn, those're purty... how'd ya make 'em?"

"Well, I got this Dremel and some wood blocks with some JB Weld..."

"Jeeze - If you don't want to tell me the truth, just say so!"

A very timely post and nice work. Just yesterday I was looking at places to buy some 1075 bar stock to make some arrowheads, but I wanted thinner than 1/8.

Very nice work, the dremel jig had to take some time to come up with.

Question on using the saw blade. It appears to be a worn out carbide tipped blade? Is the steel very hard?

I know before carbide tips came out, saw blades were made with pretty good steel but I have always been under the impression that they were pretty soft (and not hardenable) after carbide became popular. I tried cutting up a cheap plywood blade (non carbide) that said it was "chrome moly", but it wasn't very usable and I gave up on saw blades after that.

 

[DIY_guy]

No this is NOT a carbide tipped blade. Thats why I chose it for this project because the base metal of the blade is suitable for edge holding.

Bear wont give a hoot about the color of the broadhead. Their eyesight sucks. Besides, the bear will only get a head on view and it will be spinning and traveling towards him very quickly. ;-)

Thanks, that is some innovative craftsmanship.
