Airgun lubrication — gas guns

by Tom Gaylord, a.k.a. B.B. Pelletier

Airgun lubrication — spring guns: Part 1
Airgun lubrication — spring guns: Part 2

This report addresses:

• Molecules versus atoms
• Crosman Pellgunoil
• Can’t over-oil with Pellgunoil
• “Fixing” leaking guns with Pellgunoil
• Transmission stop leak oil
• Oiling moving parts
• Ballistol

Let’s look at lubricating gas guns — and by “gas,” I mean CO2. What I’m about to say will also work on airsoft guns that operate on green and red gas, because both those gasses work similar to CO2; but there are no pellet or steel BB guns that run on any gas except CO2 (excluding air). read more

Diana 72 youth target rifle: Part 1

by Tom Gaylord, a.k.a. B.B. Pelletier

Diana 72
Diana 72 is a youth target rifle from the late 20th century.

This report addresses:

• History of the rifle
• The Giss contra-recoil system
• General description and dimensions of the Diana model 72

Today, we’ll begin looking at an air rifle that I’ve been waiting 3 years to share with you. In 2011 my friend Mac and I were looking at his vintage air rifles to see which ones would be of interest. We actually did a report on his Diana 60 target rifle that was labeled a Hy Score model 810. The rifle needed to be rebuilt, so the velocity was low, but the accuracy was right on. The report was so successful that he decided to test his Diana model 72 youth target rifle next. read more

The Colt Python BB revolver: Part 3

Part 1
Part 2

Colt Python
Colt Python from Umarex looks like the real deal!

This report addresses:

• Sighting in.
• Corrections to the manual.
• Accuracy at 16 feet, 4 inches (5 meters).
• Accuracy at 25 feet.
• Summary

Today is accuracy day for the Colt Python BB revolver. I know this is a test many readers have been waiting for, and I think it’ll be worth the wait!

I shot the revolver from a rested position, using a 2-hand hold with my hands forward of the rest and unsupported. My forearms were resting on a cushion, and the revolver was steady in my grip. The target was lit brightly, so the sights were in sharp relief. read more

2014 Toys That Shoot Airgun Show: Part 2

by Tom Gaylord, a.k.a. B.B. Pelletier

Part 1

Here’s what we’ll cover in today’s blog:

• Correction to the first report.
• Some vintage airguns.
• There were parts for sale.
• Vintage store displays and boxed BB guns from WW II.
• Ft. Worth airgun show.
• NRA Annual Meetings and Exhibits.

This is the second part of the report on the Toys That Shoot airgun show in Findlay, Ohio. In the first report, I showed you a lot of vintage collectible airguns — some commanding very high prices. Today, I’ll show the other side of the show — the one where regular people would buy and sell. Before I get to that, though, there is a correction to the first report. I mentioned seeing a muzzleloading big bore air rifle on Dennis Quackenbush’s table, and I gave you the impression that he designed it. He did not. That rifle was designed by its owner, Mike Paulus, who commissioned Dennis to build his design. Dennis told me as much at the show, but I wasn’t listening. I thought he was being modest; in fact, he was telling me that Mike designed the rifle. Dennis just made the parts for him. read more

Daisy 880: Part 4

Part 3

Daisy 880
The Daisy 880 multi-pump is a classic.

This report addresses:

• Examining a new Daisy 880S sent from Daisy for this report.
• Examining the test data Daisy sent with the rifle for pellets and BBs.
• Running the same velocity test as I did for the first two 880s tested.
• Testing this new rifle with RWS Hobby pellets.
• Testing the new rifle with BBs.

This test is unprecedented. In Parts 1 and 2, I tested my own Daisy 880; and when it failed to achieve the velocities several readers felt it should, I ordered and tested a second brand-new 880 supplied by Pyramyd Air. That rifle also failed to live up to the velocity claims. When there was a question about whether all 880s are Freimarked (the letter “F” inside a pentagram is marked on the outside of a gun to indicate it develops no more than 7.5 joules of energy at the muzzle) for the German airgun market, I asked Joe Murfin, vice president of marketing at Daisy, to clarify this for us. He assured me that all 880s and their related variants are Freimarked, but that the mid-500 f.p.s. velocities I had gotten from both airguns was on the low side. read more

Building the $100 precharged pneumatic air rifle: Part 6

Part 5

$100 PCP
The PCP is built on a Crosman 2100B chassis.

This report addresses:

• Mounting a scope on the rifle
• Shooting Air Arms Falcon pellets at 25 yards
• Grouping in smaller pressure bands
• Shooting Crosman Premier lites
• Marketing the $100 PCP

This will probably be the final report on the $100 PCP. It’s been an interesting project, and today I’m capping it off with a test at 25 yards with the rifle scoped. I selected a UTG 3-9X40 scope with illuminated reticle and a one-inch tube. This is a wonderful scope for just under $100. It’s smaller size suits the test rifle perfectly. read more

Airgun lubrication — spring guns: Part 2

by Tom Gaylord, a.k.a. B.B. Pelletier

Airgun lubrication — spring guns: Part 1

This report addresses:

• Identifing and lubricating high-stress parts
• Lubricating with moly
• Lubricating triggers
• Lubrication intervals
• Lubricating mainsprings
• General lubrication
• Preserving the airgun with oil

Well, the immediate response we got to the first installment of this report made it one of the all-time favorites. In that report, we looked just at the piston seal, which I said was half of the lubrication solution for a spring gun. Today, we’ll look at everything else.

Parts under high stress
The moving parts of a spring gun are the powerplant parts, the trigger group and either the barrel, when it’s used as to cock the gun, or the cocking mechanism if the gun isn’t a breakbarrel. When airguns were simpler and less stressed, all of these parts could be lubricated with gun oil or lithium grease. But today’s guns are stressed to higher limits and generally need something more specific and better-suited to each application. read more
