View Full Version : Wonder if I broke a spring?
WBZsDAD 11-27-2008, 07:49 PM This evening my oldest son (The "W") and my youngest son (The "Z") where out shooting for a while (via flashlight pointed at the target), after they were out for a little bit I went out and grabbed the Recon and shot it, and it seems to be way louder (twang wise) than it was before. Do you think we broke a spring? I shot it today and i didn't notice it being that loud.
craigfperry 11-27-2008, 08:08 PM take the stock off an have a look thru the slot and see if you see whats what.
if it broke it would be near the trigger.
WBZsDAD 11-27-2008, 08:25 PM Craig, if I understand you correctly it looks like it's near the trigger to me......Broke?
I don't really want to tear it down yet cause I don't have any lube, I ordered some from JM last week.
craigfperry 11-27-2008, 08:29 PM if it were broke the coils would be touching.
recons have the habit of being twangy.
if you find you need a spring i have one.
WBZsDAD 11-27-2008, 08:36 PM OK I appreciate it, I guess I'll shoot it some more tomorrow, and hopefully my tar will be here soon,
I really want to tear this down cause I have an idea for a spring compressor that I think is going to be very simple and affective so I am anxious to try it. still gonna wait fer the lube tho.
Thanks
craigfperry 11-27-2008, 08:42 PM you can break it down being careful not to disturb the old lube and then put it back together.
it looks to me from your pic that the spring has lube to spare.
be careful with that compresseor, you don't want to be wearin any parts.
WBZsDAD 11-27-2008, 09:30 PM Roger that! It will be my first teardown on a springer so I am not experienced here but I have plenty of experience with tools, machines, recoils, and the like so I know a spring can hurt a man quick!
Thanks, I'll post some pics of the SC if it goes well and is worth sharing. I'm making it out of an old woodworking/furniture clamp. It's like a bar clamp but instead of the round pipe jobs it is a flat bar, much better clamp than those crappy pipe clamps. I don't even know if they make these anymore; they were my wife's granddaddy's.
craigfperry 11-27-2008, 09:32 PM well git to it.
craigfperry 11-28-2008, 07:02 AM how did it go?
WBZsDAD 11-28-2008, 07:57 AM Didn't do anything yet, I had some ladies from my Church use my shop for about 3 weeks for a missions project........(yes I lent my shop out), so before I can do it I have to dig my table saw out..........looks like an early day so maybe today.
craigfperry 11-28-2008, 08:10 AM once you get into it and see how easy it is your gonna wish you did it a long time ago.
i have a trick to help the twang until your tar arrives.
WBZsDAD 11-28-2008, 08:18 AM I love to learn new tricks, watcha got?
craigfperry 11-28-2008, 08:24 AM take the spring guide to the hardware store and find the nylon spacers.
find one that fits over the guide and is 1/4 or 1/2 inch tall.
slip it over the guide and reasemble, this will tighten the spring a bit and help to quiet the bad vibes your getting.
WBZsDAD 11-28-2008, 08:41 AM That makes sense, it seems like if you put 2 of them 1/4" it would allow them to rotate on each other, rather than putting one 1/2". It seems like the spring end would catch on the nylon or start to dig into the bushing over time, True? Assuming that the spring rotates when cycled. I will do that though for sure. Thanks
craigfperry 11-28-2008, 08:47 AM i don't think you will find one that is 1/4 i think you will find a 1/2 that you can cut in half.
nylon holds up well when used for this task, i have not seen any deteriation of the nylon when i have done this.
now git to it already and post some pics.
I made a set using steel washers for my recon before putting the Storm spring in there. I thought of the same thing - adding 2 to the rear but didn't feel like dremeling another one. It works great as is. As for the front, I used a tophat out of a crosman since the recon didn't have one to start with and added a washer in between the tophat and spring as well.
easy on that stacking washers stuff.you could easely make a new spring an old maid.
do the math.
craigfperry 11-28-2008, 05:38 PM how bout you give up the formula for those that know not.
WBZsDAD 11-28-2008, 07:18 PM This spring is slightly under a load or at least it has slight tension on it in the position depicted in the first picture (I was holding tension on it with a small steel rod while taking the 2nd picture).
Now back to the spacer deal, do you think it needs a spacer given the fact that it has tension on it as soon as it does? The whole spacer thing seemed very logical when you told me about it. However I had a visual in my head that the spring might be almost relaxed when fully installed, and that the twang may be a result of the slack, maybe I had it wrong.
Is the purpose of the spacer to dampen vibration or take up slack? Because as you can tell it definitely doesn't have slack when installed.
Also can you tell from the pictures if it has too much lube or?? Sorry to make a mountain out of a mole hill here but uhh.....I don't have a clue....well I have a clue but that's about it.
craigfperry 11-28-2008, 09:53 PM it's not going to hurt to try a spacer just to see, if i remember correctly my recon had 25 mm of availible spacing so i went 10 mm then after that i went to a used G1 spring and tophat.
the vibration is more the result of poor fitting spring/guide and the lack of a tophat and is probably occuring inside the piston (you may be able to see it if you look carefully.
that lube looks like ass, same as was in mine, your stuck with it until your JM lube arrives and it is little much.
try to relocate some of it to the inside of the piston.
WBZsDAD 11-28-2008, 10:57 PM As you can imagine Craig, I have a question, what do you mean by "25 mm of available spacing", I assume you mean the amount of space you had left in the tube after the spring was compressed; what i don't understand is how you knew that?
craigfperry 11-28-2008, 11:17 PM available spacing
when you cock your airgun your spring usually does not compress as much as it could so you have available spacing.
spring coil dia. x number of coils will give you compressed spring length.
now take a measurment from the inside top of the piston to the end of the compression tube while the piston is in the cocked position.
then subtract the length of the thrust washer and spring guide and tophat.
then subtract compressed spring length from this measurment and this is your available spacing.
know what i mean.
WBZsDAD 11-28-2008, 11:35 PM I think I'll just guess, wish I could get my hands on a top hat, I bet that fixes lots a twangin
craigfperry 11-28-2008, 11:43 PM yes a tophat would help.
the worst that will happen from guessin is that it won't cock and you'll have to go back in and remove some of the spacers.
njphil 11-29-2008, 05:43 AM yes a tophat would help.

Been there done that, on my Viper. I had that sucker apart 4-5 times that day. But there is a up side I got good at it.:thumb:
wbz pm me your address - I'll send you a crosman tophat...
