![]() He was a subscriber of The Airgun Letter who wanted to share this with all the folded-metal BB gun collectors in the world. Once again, the credit for this machine goes to the late Jerry Voich. Reprinted with permission of Daisy Manufacturing Company. You can compare the plunger assembly in the photo to the older one in the schematic. This schematic is for illustration, only. It straightens out after passing through the swaged-in plate at the front of the compression cylinder. The silver tube at the top of the assembly is the air tube or transfer port. This is representative of what’s inside most Daisy BB guns. You can see it at the bottom of the photo. On this one, the spring anchor is part of the assembly, rather than a separate part. This plunger assembly is from a modern Red Ryder. It takes a ram with forked legs to reach around the spring anchor and push the mainspring forward, and that’s what the disassembly/assembly machine provides. The tension on the mainspring is relaxed, and all the powerplant parts can be removed from the back of the gun. Forcing the mainspring forward takes pressure off the anchor so it can be removed. The way to remove the anchor is to reach around either side of the anchor and put pressure on the mainspring, which is wrapped around the plunger casing (spring guide). ![]() Then, the tension is relaxed on the mainspring, and the powerplant parts can be slid out the back. The one big secret to BB gun disassembly/assembly is to take the pressure off the spring anchor so it can be removed by simply lifting it out of the gun. 102 Model 36 is a simpler BB gun that incorporates its rear sight into the mainspring anchor. On this gun, the spring anchor is just a dedicated metal plate that sticks through the top of the gun. I don’t own a Red Ryder, but this 499 is constructed very similarly. Its backside is what the plunger (piston) rests against and in the front, it contains the screw threads that the shot tube screws into. This plate forms the front of the compression cylinder of the gun. On the front end of the plunger assembly, there’s a plate that’s swaged into the tinplate body of the gun. When the gun is assembled, the plunger casing (mainspring guide) is pressing backward on the spring anchor, which holds it in place. Daisy calls the piston a plunger and all the parts are plunger parts. That leaves us with the powerplant, which consists of the mainspring, the piston assembly and the spring guide. In the case of the trigger, there’s a return spring that also comes out with the blade. The trigger and cocking lever are then removed by removing more obvious bolts. Taking as an example the Daisy model 1938, most commonly known as the Red Ryder, we can remove the buttstock and forearm by the removal of several obvious screws and bolts. After this step, the guns become more specific, though the assembly of most of them remains the same. This is accomplished by simply unscrewing the tube and removing it from the gun. The first step is to remove the shot tube. Find an easy way to remove this one piece, and the whole job of disassembly becomes easy. The powerplant of most Daisy BB guns is held in the gun by a spring anchor, which is a flat piece of steelplate that fits through the body of the gun. The design of this machine was given to The Airgun Letter by the late Jerry Voich, who authored an article for us on BB gun disassembly. Without this machine, you need extra arms and hands at various times in the procedure. You will soon see that rather than a report on just how to disassemble BB guns, this is more a report on how to build a disassembly machine, because that’s what it takes to do the job. If slight differences are encountered, it should be easy to adjust your methods to accommodate them. However, fundamentally, most inexpensive BB guns are designed and assembled in pretty much the same way. Older and newer guns may vary a little or a lot from the ones shown with this procedure, and there are models within the same timeframe that vary because of their unique design. Therefore, this report will deal with those Daisy guns made from around 1915 to around 1970, which includes a large segment of what’s on the used market today. As we consider this operation, we must acknowledge that BB guns come in many different styles, and they don’t all come apart the same way. Today’s report is for Bob from Oz, who asked for it long ago and has been more than patient. On Thursday I’ll start the Nitro Piston review.
