View Full Version : Need some "techy" help!

Got a small problem someone out there may have a good fix for. The Cavalier Master plunger I have in my Best Zenit riser keeps coming unscrewed. I wrapped a piece of leather around it and tried to scrunch it down with a pair of pliers. Yea, the leather slipped and now I've scared up the plunger (never was good with tools - LOL).
Anyway, went out to practice the field course today and after a couple targets the thing was loose again. Couldn't finger tighten it enough to stay. About every third or fourth shot the bow would buzz like a rattler (saw one of them today too...a Mojave) when the plunger came loose.
Thought about locktite but if I tune again I will surely screw it up even more gettin it loose. Any lock washer or gasket ideas?????

If the lock nut won't set it good enough to stay, you might want to try dripping some melted beeswax on the threads. It'll keep any moisture out and beeswax works great as a light duty loc-tite.
DA,
Another option is to put a couple of wraps of teflon sealing tape on the threads and screw it in. Sounds odd but the tape will keep it from moving on it's own. No mess either. You can get a small roll cheap at any place that has plumbing stuff. Be sure to wrap in the right direction or it will just wad up when you screw it in!
DA,
You probably already know this, but those mojave rattlers have a more potent bite than most rattlesnakes. They are hell on dogs!

Yeah, plumber's thread tape...
If that doesn't work, clamp a small pair of Vise-Grips on it... permanently. LOL

Dave, loctite makes a product for small threaded screws and bolts. Its not as strong as the regular stuff and will come undone when you want it to. Other than that, the lock washer with the multiple tangs might work, but take a real good look, maybe the theads on the nut are stripped already and that is what the real problem is.

Id weld it place if I were you. LOL
That teflon tape should do the trick. Just ask for white plumbers tape at any hardware store.

Check first to see if the threads are still ok, not buggered up or cross threaded. If they are ok it maybe just a min/max mfg tolerance thing and you'll need to fill up the sloppy gaps with something like the teflon tape or a few twists of FF bowstring thread. Wax will work too, until it gets warmer out, I use it a lot on target point threads since I have a bunch of left fletched arrows.
Any decent hardware or auto parts store should carry several grades of loctite. and the lighter grades are helpful in keeping things tight but still removable. I used it a LOT in my compound days. If neccesssary you can glue it in with one of the cheaper fast set epoxies. a small amount of the 5 or 10 min. set stuff will hold it and if it needs to be moved a little heat with a cigarette lighter will soften it enough to move it
You might also look at putting a "jam-nut" on the threaded shank of the plunger to tighten it up against the riser. It'll put tension on the threads so the threads have to be ok.
If the threads are messed up it might be possible to clean them up with a propers sized and threaded tap for the riser and a die for the plunger tube. Hopefully the plunger tube is brass or something softer than the riser material

Dave,
The Loctite 222MS threadlocker will work. Breaks loose with little effort.
Pricey stuff but a small bottle goes a long ways. Great for rifle scope mounts also.

Locktite comes in differnt types,the type for screws is removable and is what I used on my hard cam bow with no trouble.check the lable I think it,s the blue stuff but I haven,t used it in awhile and don,t have it in front of me to check.
One of the wheel shooters on my league uses string wax to keep his points tight maybe that will help with this also
Good luck!!
Shoot striaght and have FUN!!

Now why didn't I think of the teflon plumbers tape myself (laugh's on me this time). Thanks for the idea guys, and the other suggestions too. The wax would be great until summer here in the desert...bet it would be loose again (smiley face goes here).
The threads are in good shape, the scratches are on the nut that tightens against the riser. That's where the pliers slipped. Oh, and the barrel (shank?) of the Cavalier is stainless while the riser is what ever aluminum alloy Best of Italy uses.
Yea, the Mojave venom is both a hemotoxin and a neurotoxin. Not supposed to be fatal to a healthy adult, but it will make you sick enough to think you're dying. They are also the most agressive of the North American rattlers. This one was headed right for me across the opening where the shooting position is for target #8. I'm 6'3" and this little sucker was only about 2' long but he/she wasn't intimidated a bit (LOL). The desert ain't a good place for the weak of heart (or head - LOL again).
Thanks again for all the help folks. That's what I love about this place.

If I,m not being to techy-
My I suggest a spot of your wife’s finger nail polish on the threads. :D

Nope, bad idea, all of her colors clash with my riser colors. :crymeariv

regular string wax is OK, but gets mighty thin when it's hot outside. Beeswax has an extremely high melting point.
The plumbers tape should also do the trick very nicely. If not, the threads may be pretty well shot. And if that's the case, all is still not lost. Several coats of super glue (allowed to dry completely) inside the bushing will allow you to cut new "replacement threads" with an allen bolt that fits it.
The nail polish is a good idea if it's the threads of the plunger that are the problem.
Usually, the lock nuts are enough to secure it very nicely if the threads are in good shape, but it sounds like that may not be the case of for you. YOu've got some pretty economical and effective ideas to try, so let us k now how it goes?!
DA,
I grew up in Tucson, lived there 21 years. You're right, everything down there either stings, sticks or bites!! Mohaves are the only rattlers that have actually come after me. Most of them ended up marinated in BBQ sauce and baked!

String wax has worked well for me.
Got better yet when I replaced fast flight with 8125 and tuned my equipment so it did not vibrate so much... :)

DAS,
In my younger days it was SOP for folks to shoot any rattler they came across. Since I got back into archery, both in Tucson and up here, the field ranges I shoot on are in county parks. Big time restrictions on killing any wild life.
The Mojave was sneaking up on me (well, it looked that way to me) while I was shooting target #8 which is a 65 yard shot. It takes a lot of concentration for me to make those long off ones and I was trying hard to get some 4s. When I got done and just started to walk toward the target I spotted this little 2' sucker over my left shoulder. He wasn't coiled but rather stretched out for traveling, pointed right for where I had been standing. I didn't panic or anything but since you've been in the desert you know that funny feeling you get when you come upon a rattle snake unexpectedly at fairly close range. It just makes certain muscles tighten up (I ain't gonna go into details).
Actually it was a good thing. Now I will keep my eyes open every time I go shoot the course. Them suckers is everywhere (LOL)!

Figured I should tell you all, the plumbers tape worked like a charm. Finally got around to doing it (been tuning other bows in the mean time) and it is solid and secure. Not a buzz to be heard anywhere.
Thanks for all the ideas and help. I still think this is the best site on the web!
Dave
DA,
Awesome! too bad it isn't effective snakes :)

Who'd have thought plummers tape was "techy"? :) Glad you fixed her.

Does it come in camo???...LOL...warf
Nah! It's not high-tech :)

This is the first time have heard of teflon tape referred to as plumbers tape. Plumbers call perforated strap plumbers tape. :)

Wait a minute!
Isnt plumbers tape what holds their pants up and hides the "cheek" division? :shooting: Ouch!
No silly! That's plumber putty! :lol:

OK, guess I screwed up calling it "plumber's tape". I never was much for home handy man crap anyway!!! Technically (and this was a thread about "techy help") the package calls it "Teflon Pipe Thread Tape", so to make you happy...
I fixed the plunger that was vibrating loose with Teflon Pipe Thread Tape and now it stays put (shot the 60 arrow NFAA 300 today to be sure). Thanks again for the recommendation, what ever the heck the name is (smiley face goes here).
