How do I lighten the trigger pull on a 'Cat? (Trigger Job)
Look at ICD 'Cat Tweaks: Trigger Work and Bolt Polishing at pRCarter's site.
The easiest things to do are cutting the trigger return spring, and polishing the top of the sear. Polishing all of the moving parts is a good move, but takes a lot more work.
The screws on my 'Cat are nasty and rusty. How can I fix/prevent this?
The best solution is to replace every screw in the 'gun with it's Stainless Steel(SS) equivalent. This is a total investment of about $3-$5 and gives you screws that won't rust or swell, and always look really cool. ;) Below is a shopping list and location for each screw.
By the way, if anyone knows where I can get 3/8"X24X1/2" SS Socket Head Set Screws in quantities smaller than a case, let me know. These things exist, I'm sure, but no one sells them in reasonable numbers.

1 8-32 x 3/8" Socket Head Set Screw Velocity Jet
1 3/8"-24 x 1/2" Socket Head Set Screw Mainspring
**This size is hard to come by. I found that it was easier to buy 3/4" long screws and cut them to match the original. Yet another reason to own a Dremel.
***These screws are held in with Red LocTite. It seems like overkill to me, but it does prevent them from EVER coming out by accident. I have replaced mine, but not yet measured them. I'll have the size and replacement procedure soon.
Recock Dial Adjuster
I stole this one off of Fun Supply's ICD Discussion.

Have you ever set your ThunderCat's recock so the gun is nice and quiet only to have it start "burping" and not recocking later on that day, right at a crucial moment in the game? Ever wish you could just turn a knob just like the 'Cocker shooters and crank it up a touch?
Well, you can! Just replace the stock recock set screw with a thumb screw with 8-32 threads. The threaded section should be about 3/8" long or even a tad longer. This works great and you can get these, in a number of different styles, at most hardware stores as cheap as $0.15 a piece. I have a number of metal ones for my gun but it's currently wearing a nylon screw with knob I bought and cut to length with an exacto knife.
There's just one thing to remember: When tuning the recock on your gun, these bolts with flat tips require you to open up your recock only about HALF as much as you would with the stock set screw (which is pointed).

Ed. Note: I've found that appropriate knurled shoulder thumb screws can be found in hardware stores under "Storm Door Fasteners." If you have a Dremel or something similar you can cut it to the right length and round the end to make it work like the stock screw.

Velocity Dial Adjust
This can be done in two ways. The first is to follow the instructions for the recock adjuster and replace your velocity jet screw with a thumb screw. It might be difficult to fund a screw long enough, though.
The other method is to get a 3/8"x24x1" socket head cap screw and replace the mainspring adjusting screw. The problem with this method is that you end up with about an inch of screw sticking out of the back of the 'gun unless you have the velocity cranked way up. Oh well.
The best combination is to replace the recock and mainspring screws, and leave the small set screw in for the velocity jet. This makes for easy tuning without a lot of junk hanging out of the gun.

Keep in mind that any of the dial adjuster mods are probably NOT tourney legal. If you plan on entering any tournaments, keep the original screws handy. If anyone has an idea for a dial adjuster with a tourney lock I'd love to hear it.
