Illudium Q-36 Explosive Space Modulator
Got my new Marlin 39a and while the lever cycles great, it could be greatly improved upon. So, I decided to take it apart to see what was up. To my surprise, there was A LOT to be improved upon. Machining marks EVERYWHERE, gritty surfaces, as well as rough grinding marks that looks like they ground the part to fit right, not taking the time to finish it up. 
Anyways, my plan was to bust out my dremel and polishing pads/compounds as well as some super fine grit sanding disks and to go to town touching up what Marlin didn't. Afterwords, my plan was to apply some cold blue to refinish what I've worn off.
So long as I don't go nuts with material removal, do you suppose I could really hurt anything by smoothing and polishing the flat surfaces that slide against each other? From my perspective, I could only improve on what I've already got.
Thoughts?
