More than likely, your Remington saw better days. Even though your KED grade firearm may now have lots of issues, that doesn’t mean it is beyond salvage. In fact, some basic gun repair tips and tricks will show you just how easy it is to improve the condition of this vintage firearm. Today’s how-to guide will help you become familiar with all the concepts on how to repair a Remington 1900 double barrel shotgun. We will cover what this entails and will also address a common issue with this model: fixing the fore-end latch.
Useful terms for fixing a Remington 1900 double barrel shotgun
KED grade – The K stands for the basic grade, the E for the automatic ejectors, and the D stems from the weapon’s Damascus barrels.
‘Numbers-matching’ – If you own a Remington 1900 double barrel shotgun, your firearm will have the same serial numbers inscribed on the barrels, receiver, fore-end, and on several of its smaller parts. These numbers help manufacturers hand fit these shotguns when they initially assembled it.
How to fix a Remington 1900 double barrel fore-end latch
Some of the most common issues you may come across at this stage include barrels that are off the shotgun’s face (i.e. not attached to the receiver) and a fore-end that no longer stays attached.
Step 2: Fashioning a new fore-end latch
This small spring, usually refers to a Baker-style latch. This latch was patented in the 1880s. It holds the fore-end to the barrel. First, take the fore-end apart. Unscrew the two screws and take out the cross-pin with the support of a bench block. This piece holds the wood to the barrel. Use an original working latch as a model. You must fashion a piece of spring steel flat stock into a similar shape.
Figure out how big you must make the cross-pin hole. Generally speaking, a number 35 drill will usually yield a hole that’s just big enough to allow for the latch pin to rotate as it needs to. Use a protective cover on the steel stock followed by an automatic center punch to determine where the hole needs to be drilled. Center-drill it. Then, make a number 35 hole.
Saw off the piece of steel to match the shape of the latch. With a 10-inch hand file remove the bulk of the material and establish the correct width. Then, forge the front end, which is a little wider. Torch the metal to the point where it is red hot. Next, use a 24 oz. hammer to bend the metal to the shape you need.
Step 3: Filing and shaping
Once the metal cools, you must file the latch to the appropriate taper. Then, shape the curve of the latch with the use of a torch to heat the metal. Follow this up with a big hammer. File off the remaining excess material to match the exact shape and size of the material. Just remember to add protective coating to the metal before using the file. Once the latch has taken on the correct shape, saw it off to the correct length.
Step 4: Testing and polishing
Install the new latch to make sure it holds the fore-end iron safely in place. Once you complete this test, you should use sand paper (finishing with 320 grit). The sand paper adds the finishing touches to your new latch. Back the sand paper with a small file. Remember to only polish the metal across its length. Scratching it crosswise may eventually cause breakage at the surface.
Step 5: Hardening and tempering
First, heat the metal to the point where it literally become red hot. Quickly dunk it in clenching oil. It’s better to use oil rather than water since water may cool the metal off too fast and cause cracks. Once it cools down, the metal will cease to be brittle. Before you temper the latch, file off some of the scalier bits on its surface. These parts emerged as it stood there hardening. Finally, temper it by dipping it in niter bluing salts which you heated to 600 degrees beforehand. Allow the steel to turn blue. Finally, dunk it in the water.
There you have it. You successfully repaired your Remington. Now give yourself a pat on the back for a job well done.
