Dissassembly of a S&W Model 36 - Should I be intimidated?
Mods, if you feel this would be more appropriately answered in "The Smithy" I won't be bothered if you chose to move this there.
This thing is pretty old, I think when I looked up dates on the serial numbers it was made around 1958 give or take a year. This thing has probably never been opened up and cleaned. If it has been, it has at least been in the terms of decades. DA pull is too hard, and I just know that the old gun has a lot more potential than it has right now. I have a desire to take it apart, give it a good cleaning and oiling, might even go as far as installing a spring kit. I have taken apart most of the firearms I have access to and they all went back together. I have been studying youtube videos on taking them apart. I would probably order the rebound spring tool from brownells because I know enough to know that the rebound spring is one of the biggest hurdles in taking one apart and putting it back together. I feel pretty confident that I can take it apart and put it back together. Any tips from people who have taken apart j-frame Smith & Wesson revolvers? |

You can probably do it, but it's not necessary.
Get a can of brake parts cleaner and just blow all the old oil and crud out of the inside. Then, spray the same areas with WD 40 to get lubrication and protection into the gun's nether regions, as the brake cleaner will remove all the oil from inside the gun. Be very careful not to get this stuff in your eyes, and rubber gloves are recommended. Dry the gun thoroughly, and use a good oil like Quick Release on/in the gun. |

Sure, give it a whirl. Below is a link that might help. There are likely some YouTube vids on the process, too.
Be aware the j-frame's spring is a coil, rather than a leaf, as shown in the link. Also, I'd remove tension in the mainspring before removing the sideplate (it's done after in the link). Read over the process beforehand so there's no surprises. A little bitty spring that launches tends to put a damper on the fun. When in doubt, do the disassembly in a shoebox or even a ziplock bag. Use a screwdriver with the proper hollow ground bits. Don't use WD40. It's designed as a Water Displacer, not as a cleaner or lubricant. Besides, there are plenty of quality gun cleaners & lubes available. If you don't want to spring for an actual gun lube, use ATF. http://www.thehighroad.org/showthread.php?t=397027 |

I taught myself how to disassemble S&W revolvers simply by observing what was going on with the sideplate off.
Regarding the sideplate... NEVER EVER attempt to remove it by prying it off! You'll bend it, bugger the frame, and it will never look right again. I use a Phillips head screwdriver for my rebound slide spring removal. Works great. The best reason to disassemble is so that you can properly lubricate the internals with a layer of gun grease. Grease is FAR better than oil in the closed environments of a Smith revolver as it stays where you put it. Oil slowly (or quickly) runs away, leaving you with a dry gun that is difficult to relubricate. And, I have to disagree with the advice to use WD-40. It is far too light an oil to provide any real long-term lubrication value, and it can (being a penetrating oil) get where you don't want it, such as the primers in rounds that are carried in the gun.

Do you have a gunsmith screwdriver?

Mike is absolutely correct about not trying to pry off the side plate. Don't do it.
However, he stopped short of telling you how to remove the side plate. With the screws removed, hold the gun in one hand with the side plate down in your palm. Smartly rap the gun on the other side with the handle of your gunsmith's screwdriver. The sideplate will start to move. Rap it again if necessary, until you can turn the gun over and lift off the side plate with your fingers. Be careful about how much the side plate moves when you tap it. Stop tapping when you can lift off the side plate. You don't want all the action parts to come out in your hand. You want to be able to see them all in place in the gun so you can observe how they inter-relate. |

Things that I have found that make the double action harder than it should be all have to do with the cylinder and "miscellaneous crap" buildup in the area around the ejector rod, on the yoke. That's a technical term, btw. Disassembly is easy, and you should not be intimidated. Reassembly can sometimes require 2.5 hands, but it's not all that hard once you get the hang of it. The most difficult part will be the smaller springs and avoiding escape velocity when reinstalling those. The mainspring is a cinch with a small pin used to capture it.
In my opinion, Smith has one easy to disassemble revolver there. I break my 637 down every time I have a long shooting session, as I shoot cast through it, but I don't yank all the guts out of the gun. It's mainly just a cylinder breakdown to get the lube, lead, and carbon out of the parts that are supposed to spin. As mentioned, the internals are best dealt with with some chlorine free cleaner of some sort and liberal finger pressure on the nozzle, also known as the "shoulder thing that goes up." Dental picks and the nylon versions are great for buildup in these areas. A couple things to remember in all of this is that smith cylinders are reverse threaded and that excessive force is not your friend in the disassembly. I have had a few Smiths that have red loc-tite on the side plate screws and yoke screw. Other than that, there are no real problems. Make sure you use a well-fitting screwdriver blade for those screws. Of course, if you bugger them up, add some more to your next Midway or Brownells order if you're worried about the unsightly appearance. Buggered screws and side plates are a good indicator of bubba-smithing and will hurt the gun value next time. Since you've gone through the trouble to take it apart, lube it up in there as well. You don't need it to be leaking oil into your pocket holster, but there are a few areas I like to add a little grease, etc. There are some good videos on youtube, as I recall, on where to apply some lube. Also, I like to have a dremel on hand with some nylon or brass brushes for certain areas for cleaning. You don't need warp speed, and an adjustable dremel is the way to go here. I use one to get the carbon from the top strap and sometimes on the yoke/crane. |

I figured since he was studying the youtube videos on how to disassemble a Smith, he already was well versed in the how of removing the sideplate, but possibly not the why.

Hi Mike,
I didn't mean any harm. Based on what you said I went and looked at a couple of YouTube videos myself. The first one pointed a revolver directly at the camera. No harm done, but it sure made me feel queasy. Another did a good job of disassembling a J-frame revolver, so you're right; the information is there. Personally, after looking at some really stupid YouTube videos on reloading, I would not recommend them to a beginner. Thanks, Tom |

No, not at all, Tatume, you were right to call it out, and I was wrong not to explain the process.
It was early, I was being lazy...

Thanks for all the advice guys.
For those that mentioned the sideplate, I am familiar with its removal by tapping on the frame with a something that will not mar the surface and the side plate should come loose. To the question of if i have a gunsmith screwdriver, not yet. I will either order something appropriate or find/make one that works. Does anyone know off the top of their head of a screwdriver that will work for me? And I will also acknowledge that some of the youtube demonstrations are not great, others are done very well, this is why I definitely watched more than one.

I know where to get a gunsmith screwdriver. There are just so many to choose from.

This is the video that taught me to disassemble a J frame, he does a really good job of walking you through the steps. I can strip a J frame bare and re-assemble now in a matter of a few minutes.

By the way while your going to have the rebound slide off, I highly recommend swapping the factory rebound spring out for a 14lb from Wolf. It really helps dramatically with lightening and smoothing out the trigger without sacrificing light primer strikers. It is not recommended to go with a lighter mainspring however as this can lead to light primer strikers. Last edited by Dragline45; January 25, 2013 at 10:22 PM. |

In 1958, the extractor rod did NOT have left hand threads. It uses regular right hand threads and if you have to remove it (don't unless you have to for repair), tighten it very tight or use blue Loctite.

Thanks James, good to know. I just looked it up the serial number seems to correspond to 1957.

Personally, I like the fixed, blue-handled Brownells screwdrivers (not tips). I also carry a Magna-Tip set when I leave the shop. But if you want a small set specifically for S&W revolvers, again, Brownells.

If you remove the extractor rod, when you go to reassemble it, don't just stick a pliars on it and crank like hell.
If you do that, you run the very real risk of screwing up the ejector star. Put empty cases in the cylinder FIRST. They help support the star when you're tightening the rod, and the chances of bending something are significantly reduced. As for screwdrivers, WalMart's sporting goods section carries (or did not too long ago) a nice multi-set that is Winchester branded. The only complaint I have about mine is that the magnet came loose and when I remove the tip from the handle as often as not the magnet comes with it.

After decades of using WD-40 as a protectant and a lubricant, I learned the hard way of another reason not to use the stuff, especially in areas of small, moving parts. Over time, WD-40, if left in the same confined area, will (or at least can) congeal into a semi-solid, hard, waxy substance that is difficult to remove. If this hardened residue finds itself in a place where tolerances are tight for small working parts to move, it can result in a malfunctioning firearm.

WD-40 is great and I use it all the time on my garage door. I don't get it anywhere near a gun. Not only will it harden but it will mildew and ruin the finish of a blued gun.

My Smith 36 I bought when they still cost $68, that's bout 50 years ago. I just about ruined it by squirting WD40 into the works at the lifter. Now it's pretty gummed up in there and it kind of sticks. I'm not taking it apart though. I just deal with it. But I'd never squirt WD40 into the guts of any gun today. It hardens and things don't work as smooth as they did when new.

I just removed the side plate and blasted the heck out of the internals with Gun Blaster (same as brake cleaner) and let it sit for a bit before hosing it out with more Gun Blaster. Did that a few times, let it dry and oiled it up. Good to go. |
