Archery season open tomorrow here in WI and I am fiddling around making a new set of broadheads. Thanks to all the reading I have been doing because of the good Doctor. :mad:
Tonight I started on a third version. This is a 2.3 : 1 ratio head that should end up around 180 grains. I decided to try an epoxy joint to see how it will hold up but even though it has a 3,500 PSI rating, I decided to use a pin to prevent the blade from coming out of the ferrule slot (should I hit something hard and need to extract it)
This is the layout on the .039 thick M42 bandsaw blade. To the right is one of the first set of heads I made for this years hunt. It has a double bevel and no Tanto point.
After removing the shoulders from the 125 grain field point, I slotted it and drilled a 1/16 dia. hole for the pin.
Here is the blade after blanking it out and putting the single bevel on it. The hole was put in with a tiny diamond ball grinder in my Dremmel tool.
I even went so far as to bevel the trailing edge of the blade in hopes of providing even more spin. (Patent pending or course
)
here is the dry run prior to using the epoxy. It should be hard in the morning. I will take it from there tomorrow.
Actually , I couldn't go out bowhunting for two more weeks even if I wanted to so I am just having fun messing around.
