Oh heck
The trigger is awful and I don't care for the safety, it has to be pulled on to and towards the trigger to make safe!
Any way, there is an antibear device preventing a user from de-cocking it, this locks the triggers travel once the barrel is broken. I ditched that mechanism so I can de-cock it. That leaves a small stub that comes off the trigger and pokes through the trigger housing. I tacked with a welder a small piece of steel in the correct location to limit the triggers travel forward and still allow the safety to function, this loses miles of first stage. Next the sears have lots of engagment with loads of weight and creep, the adjusting screw is deliberately too short and by replacing with a longer M3 screw some engagment can be lost.
Next up is with fine stones polishing the sears with a slight angle change finnished with some 1000 wet and dry wrapped around a small stone to polish the surfaces. Now we have a good base, short two stage trigger to fully adjust with untill safe and dependable without weakening springs etc.
Removal of the main spring reveals next to no preload of the piston, I don't like this in any airgun(springers). It makes the cushion of air overcome the spring and make it vibrate.
After removal the piston skirt is polished by hand with wet and dry. Any method to remove high spots and lessen friction is ok just as long as it ends up shiny. For the cylinder I make a mop for the hand drill with some wet and dry wrapping, like a honing tool and motioning the revolving drill in and out untill reasonably shiny. If the main spring will let me as in this example I add a distance/weight piece to the inside of the piston that the spring sits on thus adding some preload. Generally this stops the "boinng" and makes for a "thud" to the action. On this Crosman it was still easy to reassemble with just hand pressure!
I use a heavy weight gear oil to lube the piston, it will diesel very slight. Many don't like this as it can make for bad consistancy but most don't use heavy gear oil
It don't like exploding and I find very consistant! I smear grease on the spring, it dampens it.
I polish the crown on these cheap made guns and lap the barrel a little with some grinding paste on a patch and rod.
Was it worth it? Yes, I now have a sweet gun over the stock item. It does well with most pellets including cheap ones. I took another rabbit after the one in the photo at 30yds +, I could only see his head and neck!
