I've thought a lot about it. I really want to do one. Last time I checked, I couldn't locate parts to make one. I had an old Primos Can laying around and I tried to cut the call open and steal parts, and the way it was glued/assembled I couldn't do it. If I can ever locate parts to make one I will absolutely do it. I even considered making a wooden shell to slide a pre-made can call into, but looking at dimensions it was going to make the call a little too bulky.
They sound really good. I like how softly you can call with these wooden grunt tubes, but they can range pretty loud, too. This one was for a co-worker. Tough to let this beauty go but I have to keep reminding myself I already have three of these.
I've had the parts for a while to make a squirrel call and finally got around to it. I got brave and decided to try the CA glue (superglue) finish option I have seen on YouTube. I figured if I'm going to cock something up, I'd rather it be something easy like this. Good thing, because I did. My CA attempt left some milky spots over the middle of the barrel and also built up in the decorative burn rings I like on my calls.
So, I sanded it all back down and started over with what I know works for me. I used a little Danish oil on the cherry body, then finished with lacquer. The dark band across the middle is a burn band done with a butane torch. I just wanted to break up the more pale colored wood a bit.
Searching online, it looks like my oil finish could be what caused the CA to go milky. Any moisture or oils under it can apparently cause the milky color. Either way, I didn't like how it built up in my burn rings and the fumes from the CA were pretty rough. Not sure I will try it again.
How about a strip of double sided carpet tape to hold the bulb on. It isnt messy, very strong, thin, and easy to remove. i have used it to attach arrow shelves and strike plates on my trad bows for years with zero failures
