If someone were to ask you which products Colt has sold over the years, would you say a .22 semiautomatic rifle? I didn’t think you would. Colt made three versions of .22 rifles, the Courier, Colteer and Stagecoach, as well as others under several private-label names for Sears, Wards and other companies. This alloy rifle shot well, but did not hold up well. Unless it was kept oiled and clean, the alloy parts wore very rapidly. In spite of this, the little Colt rifles were good enough lightweight shooters that most owners will pay to get them fixed rather than discard theirs.

Introduced in 1963, the Remington Model 1100 shotgun has been around for over 40 years now. Variations include a sporter for field shooting, a Magnum version for ducks and geese, as well as a skeet and trap model for those who enjoy breaking clay targets. In all, there have been well over 3,500,000 Model 1100s produced over this period of time so you are bound to see one (or more) come across your bench. In this article, I’ll cover some of the common problems that result in ejection failures along with a few of the possible glitches that aren’t seen very often. And, of course, I’ll examine the cures that will help you get this shotgun back in service as quickly and efficiently as possible.

Check out several videos this week: Close quarter defense requires different tactics than defense from a distance. Pillar bedding is the process of installing aluminum columns in a rifle stock to ensure there is perfect metal-to-metal contact between the action and bottom metal. Gunsite Range Master Il Ling New demonstrates the how to properly load and unload your firearm.

What's ahead for the midterms? Jeff Knox at The Firearms Coalition says, 'There might be a few Democrats who haven't been able to bring themselves to declare support for the Second Amendment, but the official party line is broad support for the constitutional right, while interpreting it in the narrowest terms, and doing all they can to undermine and dismantle it.' As for the other party, 'Republicans, on the other hand, are generally supportive of the right to arms, but few of them have any more understanding of the issue than do the Democrats. They definitely lack the resolve and the backbone to vigorously oppose the Democrats' attacks on the Constitution and the President's appointments of radical extremists to the courts and high level government positions.'

Hand-Sharpening Small Drill Bits

Sharpening drill bits by hand is a task commonly made harder than necessary. The accepted practice is to use a small gauge or a protractor to match the flutes in a perfect 59-degree (included) angle. The flutes are ground one at a time and then matched by eye to the gauge. Some gauges have length lines scribed along the gauging surface, to be used in measuring the length of each flute. These gauges are just clumsy enough to use that you are often tempted to toss the offending drill bit in the trash and get a new one.

A problem is that the gauges leave too much room for human error, something that can be compounded on each flute. There are three places you can go wrong: on flute angle, flute length, and clearance angle. Making one flute 2 degrees flat, and the other flute 2 degrees sharp results in a wide mismatch even though each mistake, when taken by itself, is small.

There is a better way. By throwing a shadow on the bit and looking closely at it in silhouette, you can quickly see the difference in the flutes and correct them at the bench grinder. The process is simple. Go to the grinder with a dull bit, put on those safety glasses and carefully touch up each flute, trying to follow the factory angles as closely as possible.

Now, hold the bit vertically in one hand and cup the other hand over the bit to put a shadow on the flutes. As long as you are facing the light—it doesn’t matter whether it’s a window, an open door or an overhead fluorescent—you should be able to see the flutes in silhouette. This is the same image you’d get on an optical comparator. Any discrepancies in the flutes are quickly noticed, and you can return to the grinding wheel to correct them.

For a drill bit to cut efficiently and on size, both flutes have to contact the work. This means the flutes need to be the same, in length and angle. Forget about that magical 59 degrees. Don’t

Above: You can check flute sharpness easily by holding them up to the light. The silhouette created will identify the differences that need to be corrected. An optical comparator would do the same thing.

Once you are satisfied with the flute angles, use the edge of the grinding wheel to thin the web of the bit. This takes a bit of practice, but there’s really nothing to it. Make sure the cutting side of the flute is close to the side of the wheel on your right and use a tiny bit of pressure to let the edge of the wheel bite into the center of the drill bit’s web. Rotate the bit 180 degrees and do the same on the other side.

When you return to the work and begin to drill, you can quickly see how well you did. If the drill produces only one shaving, that tells you that only one flute is cutting and it is time to try again. If the drill produces two shavings, note their size and shape. Hopefully, they will be similar, indicating that the drill is close to perfect.

The final test is to measure the hole. A properly sharpened drill bit will cut a hole that is within a few thousandths of nominal size. The easiest way to measure small drilled holes is to use other drill bits as go/no go gauges. Once you have a drill bit cutting on size, you can pat yourself on the back.
