Interestingly enough, the non-working gun is actually older than the working one. You can tell because it has a brass trigger and hammer. It dates from the early 1960s, whereas the working gun dates from the mid 1970s.
At the time I was much more excited about the working model, so I kind of forgot about the cheap, junk one. I figured I could use it for replacement parts or something if I ever needed them. Then, as the months passed, I starting thinking about restoring it.
The seller was right. The gun cocked and the trigger released the hammer, but everything felt very weak. The spring and plunger on the magazine were not installed correctly, which let me in on the fact that someone had tried to work on this gun in the past. This embolded me, since I probably couldn't mess it up more than it already was. With my trusty screwdriver in hand, I dug in.
When I gently pulled the two halves of the gun apart, I noticed a problem right away. The main spring was broken, and the top part was missing. There was a little rubber part rattling around inside as well. The reason the action of the gun seemed weak was that it wasn't engaging the main spring that knocks the bb down the barrel...because that part was gone. 9
Google can be a wonderful thing, and it didn't take me long to find technical drawings of the gun, and a place that sells airgun parts. I ordered a new main spring from JG Airguns and hoped that would do it.
When the spring came in, I quickly opened the gun back up and installed the new spring. I also turned the magazine spring around so it was correct. With a great amount of hassle, I got the gun back together. Things didn't seem to fit well, but I finally managed. I then went to the back yard to test it.
It was a qualified success at best. The gun now felt tighter and did, indeed, fire the bb...but only if you could keep it from rolling out of the barrel first. In other words, if you cocked the gun with the barrel pointing down, the bb would simply roll out. Barrel up, it would fire. Obviously something was wrong.
Looking at the drawings I saw a spring that I hadn't noticed before, and that I didn't have. Its whole function is to keep the bb in place until the gun is fired. It seems that whoever worked on the gun before me lost it when he had it open.
Back to JG Airguns. They shipped it quickly and I was ready. I'll show you some pictures of the install...
The four screws that hold the gun together are removed. |
This is awesome, Stu! I love it when an old broken toy or tool (in this case, it's a little of both) can be made usable again. Thanks for sharing!
