Restore Your Smith & Wesson Model 29 Through Ultrasonic Cleaning

Smith & Wesson’s Model 29 is a double-action revolver with a .44 Magnum cartridge. Its exposure in the series of Dirty Harry films, starring Clint Eastwood, made this model popular to both firearm experts and enthusiast. Being available in various lengths made the model 29 a suitable firearm for a variety of uses. A unit can come with a barrel ranging from 3’’ to 10’’. The latter became its standard and signature barrel length for a long period of time. Despite its outstanding craftsmanship and features, the Smith & Wesson Model 29’s performance can dwindle with regular use as well as exposure to dirt and dust. An ultrasonic cleaner is helpful when subjecting your S&W Model 29 to regular maintenance checks and extensive cleaning to keep it in tip-top shape.

How to Clean a Smith & Wesson Model 29 with an Ultrasonic Gun Cleaner

If you own or service Smith and Wesson Model 29 or similar handguns you will definitely appreciate how an ultrasonic gun cleaner can save time and effort when it comes to cleaning and maintaining the weapon. An ultrasonic weapons cleaner is fast, thorough and safe because unlike some solvent washers and aerosol sprays, today’s ultrasonic gun cleaning solution is biodegradable, minimizing disposal problems with spent solutions.

Here you will learn:

  • How an Ultrasonic Gun Cleaner Works
  • How to Select and Set Up your Ultrasonic Weapon Cleaner
  • How to Disassemble, Clean and Reassemble your Smith & Wesson Model 29 revolver

How an Ultrasonic Gun Cleaner Works

Ultrasonic cleaners are used in a wide range of applications to remove virtually any soil or contamination with the power of cavitation action. Cavitation action describes the implosion of billions of minute bubbles in the ultrasonic cleaning solution as they contact all components of your Smith & Wesson Model 29. The bubbles are created by generator-powered ultrasonic transducers bonded to an ultrasonic cleaning tank and typically operate at an ultrasonic frequency of 37 to 42 kHz (37,000 to 42,000 cycles per second).

The imploding bubbles quickly and safely remove grease, powder residues and other contaminants that could interfere with reliable operation of your Smith & Wesson Model 29. So tiny are the bubbles that they penetrate minute cracks, crevices and blind holes impossible to reach with conventional hand gun cleaning tools. The ultrasonic weapons cleaner will complete the job in less than 15 minutes. Meanwhile you can attend to other activities.

How to Select and Set Up your Ultrasonic Handgun Cleaner

A bench or table-top ultrasonic cleaner such as the LR617 along with its lubricating pan is ideal for sporting goods shops, servicing departments and the serious hand gun collector cleaning one or two handguns at a time. Whatever the model and size ultrasonic handgun cleaner you use there are steps to take before you start the cleaning operation by following the manufacturer’s operating instructions.

  1. Fill the ultrasonic weapons cleaner tank to the fill line (or approximately 2/3 full) with water and an ultrasonic cleaning concentrate diluted per manufacturer’s instructions. We recommend CLN-LR215 diluted 1 part to 10 parts of water.
  2. In the same way, fill the auxiliary lubricating pan with an ultrasonic gun lubricating solution and place it into the ultrasonic cleaner tank. Ready-to-use CLN-LR212 is a good choice. Make certain that the bottom of the lubricating pan is in contact with the cleaning solution.
  3. Turn on the ultrasonic cleaner and operate the unit for about 30 minutes to drive off cavitation inhibiting entrained air in both the cleaning solution and the lubricating solution. Degassing is complete when bubbles stop coming to the surface. Note that this step must be performed every time you use fresh cleaning or lubricating solutions.

How to Disassemble, Clean and Reassemble your Smith & Wesson Model 29 revolver

Disassembling the Smith & Wesson Model 29 firearm

Safety tip! Prior to taking apart your firearm, inspect whether it is loaded. Make sure that your cartridge is empty to avoid accidents. For increased safety, perform the whole procedure with the gun pointing towards an open space or wall. Do not encourage the presence of bystanders to minimize the risk of injuries. Gather the necessary tools such as screwdrivers beforehand to keep you organized throughout the procedure.

Begin by loosening the screws that fasten the grips to the frame. Once the grips are undone, flip to the right side of the gun to remove the screw under the cylinder and the two screws found on the same side plate. Note that there is a flat screw located at the rear side of your firearm. Be sure to take note of this to avoid mix-ups during reassembly.

You may now remove the cartridge by pressing on the thumb piece on the left side. Slowly slide the cylinder off to detach it completely from the main frame. Use the handle of your screwdriver to lightly tap on the right hand side of the grip frame. Doing so will push the frame away from the side cover making it easy to pull out the frame. Slightly tilt your firearm to the right to allow the hammer block to drop off.

Loosen the screw on the shorter side of the grip frame to disconnect the main spring. Separate the hammer from your firearm by first pushing the thumb piece down then pulling back the hammer. Once the hammer is in a moveable position, keep it stationary by clasping the trigger. Move the hammer from side to side to unfasten it from the main body.

For the rebound slide, take it away by lifting it up and out of the assembly. Use a screwdriver to help you with this procedure. Carry out this procedure with utmost care since the slide has a small spring attached to it. You may use a piece of cloth as a cover when performing this task to hinder the spring from flying about. Remove the trigger assembly by moving the hand backwards to create ample space between it and the frame. Gently raise the trigger to get a hold of the trigger assembly. After that, push down on the cylinder stop to lift a small spring up and out using the screwdriver. To take out the thumb piece, simply remove the screw that holds it in place.

Voila! Your Smith & Wesson Model 29 handgun has been successfully disassembled. Its parts are now ready to be cleaned using an ultrasonic cleaner.

Step 2: Cleaning the Smith & Wesson Model 29 revolver

Use the weapons kit brushes and tools to remove powder residues, bullet shavings, carbon and other loose contaminants. Tip: If the weapon is extremely dirty it should be cleaned using hot water to prepare the cleaning bath.

Put the hammer in the cocked position. Lift the star shell ejector and place a spacer between the star and cylinder to enhance cleaning action. Position your weapon parts in the mesh basket in a way to avoid air entrapment. Lower the basket into the cleaning solution and set the timer for 7-10 minutes. Cleaning time depends on the condition of the weapon.

At the end of the cycle remove the handgun components from the bath. If they are not clean replace them in the bath until the cleaning is complete. Do not reach into an operating ultrasonic bath. Remove the basket from the bath if you want to inspect or rearrange the parts.

After cleaning rinse the parts in fresh water to remove all traces of the cleaning solution, shake them to remove excess water and allow them to drain. Compressed air will aid in this process.

Return the weapon parts to the basket.

Next place the lubricating pan into the ultrasonic cleaner again making certain that the bottom of the lubricating pan is in contact with the ultrasonic cleaning solution. Put the basket into the lubricating solution and set the timer for 10 minutes. Ultrasonic waves will pass from the ultrasonic cleaning bath to the lubricating bath and thoroughly lubricate the weapon parts.

After the lubricating step remove the parts and allow them to drain. Do not blow dry. Inspect then oil the parts according to the manufacturer’s instructions before reassembly.

Step 3: Reassembling the Smith & Wesson Model 29

After restoring your firearm with the help of an ultrasonic cleaner, you may reassemble your Smith and Wesson Model 29 revolver. Begin by reinstalling the cylinder stop spring in its proper position under the cylinder case. Carefully press it in place using a screwdriver. After this, return the trigger assembly inside the main frame by pulling the hand backwards before fitting the assembly in position. Place the rebound slide inside the main frame. Make sure that springs and other small components are returned accordingly.

Screw the thumb piece back in its original location before you return the hammer. Once it is secured, press the thumb piece down to allow the hammer to get into position. You may now attach the main spring to the hammer once it is intact. Fasten the screw in the lower part of your firearms grip guide. Note that applying too much tension on the main spring can result to accidents and poor performance. Return the hammer block in its proper place between the hammer and the hand.

Cautiously cover the internal assembly of your revolver with the right hand side place. Reposition the cylinder in your firearm. Keep the plate in place by fastening it with the three screws removed earlier. Follow the same process in returning the grips in place.

Congratulations! You have just reassembled your “brand new” Smith & Wesson Model 29 revolver.

Additional Weapon Cleaning Tips

Oils that rise to the surface of the bath should be skimmed off and disposed of properly. When the ultrasonic handgun cleaner solution becomes discolored or cleaning takes longer it is time to replace it. Drain the tank and dispose of the spent solution according to local regulations. Take the time to remove sludge that settled to the bottom of the tank then clean the tank.
