2016 archery bear hunt blog (the homemade edition)

Postby DIYguy » Mon Apr 04, 2016 3:31 pm

I'll use this space to keep a journal now that Ive drawn a WI fall bear tag. I will be hunting zone D with Northern Bayfield County Guide Service

I plan to hunt with a bow and arrow as I have no interest in hunting bear with a firearm. Im leaning towards using a traditional bow and most likely one Ive made myself. I plan to make my own broadheads and arrows as well as other homemade items for this hunt. Ive taken deer with all homemade gear but Ive not taken a bear so here's my chance. I have 6 months to prepare. I will chronicle all of that here.

Im making a new set of single bevel broadheads the upcoming WI bear hunt. Im planning on using field points and 7 1/4" circular saw blades for the main blade. Im slotting the field tip (ferrule) and can peen the tip of the ferrule onto the blade but the joint at the back end is more challenging.

Over the weekend I starting messing around with a prototype. Now Im thinking of instead, using a threaded adapter rather than a reshaped field point.

Beveling made easy with the right tool for the job. I get to use my own product. (Video below)

The field points are steel and heavy. I wanted a little lighter version for the bear hunt broadhead so I switched from the re-shaped, steel, field points to aluminum 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

I used my broadhead sharpening guide to make the single bevel.

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.

As a bowhunter and CAD designer, I have designed so many profiles Ive begun keeping a catalog of all the shapes and sizes.

I like the blade just wondering if the insert will not bend on impact because length of blade?
What do you use to cut the blades with?

I cut them out using a Dremmel tool and cut-off wheels.

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.

Image

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.

Which Dremel blades do you use to cut out the profile from the cutting disk? I can get hold of a free supply of disks and would like to try it myself, and make a knife for myself.
