It’s been a while since I posted. I’ve become a lurker latelyzzz! But I’m still here and here is an example of what I’ve been up to.
Last fall I dipped into the piggy bank and bought a 60” Wong Magnum Hybrid. I had 3 Riffe MT’s before this gun and had converted all 3 to the enclosed track. I liked the Wong, but I really missed the enclosed track. My close up underwater eye sight isn’t that good and looping the shooting line over the shaft to hold the shaft in place, combined with hassles of securing a slip tip line to keep the tip from falling off, was more than I could take. Also when on the side or upside down, the weight of the shaft would cause it to sag against the shooting line and probably affected the accuracy. I felt enclosed tracks were a big improvement, and going back to sit on top rail, was just annoying to me.
So I did some research, talked to Daryl, a machinist friend, and a plastic business friend, purchased some PVDF 1” rod, and a 1” and 3/8” plunge ball bits. PVDF is a low friction plastic, but with better machining and gluing characteristics than most low friction plastics. 3 Hours of machining on a mill machine later the first friend had manipulated it into an enclosed track with a 1’ rounding on the back side to fit on the hybrid tube.
Then it was my plastics friend turn. He built a jig and glued the track to the carbon tube with PowerBond a archery glue used for gluing tip inserts into carbon arrows. It seemed to adhere well, but the only problem is the glue expands when drying which caused a small amount to leak out. It doesn’t cause any functional problems, just doesn’t look as good as it could have. The PVDF is translucent amber color. You can see the shaft and the carbon tube through it, which looks pretty cool.
Sunday I should get a chance to try it out. Dry, the shaft slides easier than it did sitting on the abs track.
I still have enough PVDF left for one more track if someone wants to pay my machinist friend to mill it. He charges $25/hour. He maybe able to do it quicker the second time.
