Help! What now?

Sometimes muzzle-loading shooters encounter mechanical problems with their revolver, so a visit to the friendly gunsmith is necessary. But here follow a couple tricks for persons gifted with common hand tools, so small repairs cost only a little bit, and help enhance self-esteem.

Unfortunately, there are no longer any replacement parts available from former manufacturers in Spain. An informed source confirmed, neither documents nor parts linger in any drawer there. Yet the hope remains that still some parts slumber at one gunsmith shop or another. The table below once attemped to swap parts of the revolver with Santa Barbara. This table is a rough guide and parts must be fitted.there is no claim to correctness!

1. broken trigger bolt spring

A broken trigger bolt spring -- the double tongue spring also known in technical terms as the trigger spring and cylinder stop -- can be annoying at first, but it is not a major problem. A new replacement part is readily available for a few dollars from any well-supplied gunsmith.   

Only a common screwdriver of proper size is necessary to change the spring. A screwdriver having a blade either too small or too large to fit the screw slot can damage the head, and unmask an amateur from the very beginning.

Let’s begin the repair. First loosen the screw from the brass trigger guard. Gently pull the guard up and back to remove it from the frame.  Now loosen the screw holding the broken trigger bolt and remove it. Now locate the broken piece. If it has fallen into the innards of the revolver, it can damage moving parts and hinder normal operation. Often it falls through the slot in the trigger guard and goes lost. Next, install the new spring and fasten in place with a screw.  Be careful when tightening the screw. If it sheers due to over-torqueing, it can be difficult to extract the threaded portion from the frame. Now check the mechanical operation.  Install the trigger guard and secure with a screw.  Double check the operation and enjoy your handy work.

2. Replace the cylinder base pin 

Heat penetration can score a magnum groove along the length of the cylinder pin when an industrious shooter makes regular use of his revolver. The following principle pertains to all revolvers: the thinner the cylinder pin, the faster the heat penetration occurs.

These problems can arise if the base pin is not replaced in time: The pin will become so weak that it will break away from the cylinder. This sheering is dangerous because, first, the cylinder chamber can drop below the level of the bore. So firing a shot when the chamber and bore are misaligned can injure the shooter and damage the revolver beyond repair. Then too, persons standing near the shooter might be injured as well.  Second, the broken base pin and cylinder cannot be removed from the frame without taking the revolver apart.

Repair of a Remington cylinder pin   is difficult to impossible because it averages only 7mm in diameter. A skilled gunsmith might be able to help, but his fee may be expensive. So the most economical solution is a new part, either an original or one reworked from a similar part.  A special-built replacement part would be expensive and the cost might well exceed the value of the revolver. At present, the cylinder pins available from ASP and Pietta are unsuitable for the Remington. They neither fit nor work properly. Perhaps in the future some Italian firearm will contain a suitable part. Meanwhile, we will stay focused.

To replace the cylinder pin the cylinder must be removed from the frame. Using a suitable screwdriver, remove the screw which holds the cylinder in place and serves as a counter bearing for the loading lever.

Then simply remove the cylinder pin and install a new replacement. Be sure to turn the curved part of the pin to rest at the top. Insert the lever and secure the screw.  Test operation—done.

A very skilled craftsman can also try to repair the pin.  But that requires skill and sensitivity for the material. The pin should be cleaned very well. Clean out the magnum groove, being careful to avoid over temping the pin.  The pin should be completely pre-heated before the welding begins and held during the work by a heat absorbing form or iron block. Then carefully lay on new material with a welding torch. Immediately grind the weld smooth, being careful not to anneal the piece. Finally, purge the repair in cold water—finished.

3. broken main sping

Broken springs seldom present a problem for the Santa Barbara New Model Army. I have never experienced any kind of broken spring in this revolver.  Nevertheless, here follow instructions for changing the main spring. Perhaps someone will want to change the spring pressure.

First select the proper size common screw driver to fit the screw holding the grip plates. Remove this screw and take off the two grip plates.

                                                    Loosen the grip plate screw

Loosen the main spring at the lower end of the grip frame and pull it away. Note, this screw will later be used to pre-load the spring.

Now pick up the revolver in a manner to prevent the main spring from falling out. Now using a piece of wood or tool handle, press the spring or push it through with small, careful blows until it falls in your hand. Now you can replace or clean the spring.

When replacing the spring, be careful to use a tool which will not cause injury. The hands and thighs are exposed when the revolver is held on the lap.

The spring is placed under the hammer then it is pushed with a tool handle into the prescribed groove. For added support place the barrel on the lap.

4. stuck percussion nipples

Sometimes, a percussion nipple becomes over time frozen in place. Generally, this condition results from over-tightening, cross-threading, excessive heat, and inadequate cleaning.

Chemical preparation

Bath the detached cylinder in Coca Cola for several hours or overnight. The cola can be used straight or mixed with diesel fuel, mineral oil, or some combination. Caution is advised because the citric acid in the cola can attack the purging and cause ugly damage.

Gentle force

Now try to loosen the frozen percussion nipple with a suitable wrench, preferably the original tool.  The interior edges of its jaws should be unworn and straight. This is important.  Support the cylinder between two pieces of copper-edged angle iron.  For easier operation, weld a flat bar to the edge of the angle. Now place the cylinder together with the angle in a machinist vice and tighten enough to prevent the cylinder from turning in the support. Avoid over-tightening the vice. Now put the wrench on the percussion nipple and shock it once with a well-aimed blow from a small hammer. The force applied should suffice to loosen any small particles burned onto the thread. Now try to tighten the nipple a little bit, then loosen and removed it from the cylinder. Repeat the procedure until new nipples are in place.

Extracting

If a nipple fails to budge, then the main recourse is to use a screw extractor, commonly called an easy-out. The spiral fluted tool should be of good quality, such as offered in the Hazet set. Use a t-bar holder to apply a well-directed, steady, downward, twisting force. Vice grip pliers provide inadequate control, and an electric drill will not work at all. 

Hazet

 

 

Begin by tightening the cylinder with a support in a machinist vice. Determine the diameter of the nipple passage, then select an extractor sized to fit the hole. The tool should be slightly smaller than the hole so the spiral flutes can cut and lock into enough metal to support a moderate twisting force. Generally, a 4mm tool is suitable for the task.  The left-hand twist loosens the nipple without contacting the thread, easing removal.

Secure the extractor in a t-bar handle, then begin twisting the tool down into the passage until it makes good contact and becomes difficult to turn. Increase twisting pressure on the handle and back out the damaged nipple.

Brush clean the internal threads and clear the hole with compressed air. Now lubricate the new nipple with oil, insert, and rotate back and forth in the hole several turns. This preparation will make the thread passage smooth gain.

7. Who can help with advice and deed

This category seeks to help the black powder shooter with some tips and tricks to help with his Remington. Most of the time, in the larger marksman community, someone knows a source for items sought. Naturally, his advice covers only what is lawful. People referring such sources lack influence on the suitability or quality.
