This is off topic, but I wanted to add to Jay's cool factory photos above. The photos are from here: https://mmm.lib.msu.edu/results.php?search=Daisy+Manufacturing+Company
Possibly cutting out the frame blanks from sheet metal Forming frames from flat stampings
Possibly making internal frame structures
Looks like testing stock strength

I don't think the original air tube was soldered onto the 'cap' because in the patent drawing the air tube is flared on the cap end, so the cap-and-air tube assembly was probably machine-pressed together and then crimped onto the body for final use. When I mentioned soldering I meant as a possible repair.
As far as a replacement for the tube (or the whole assembled part) , I think only a salvaged part from another Daisy would be found. Good luck.

Hello Kenjo7. For this post I had an old air tube assembly already missing its air tube, so I just put the base into a vise and used a screwdriver to back the crimps off enough for removal. The cap's metal crimps had enough integrity as to not 'snap off' when straightened out. Once off I did not think another air tube could be soldered on--but more nimble members out there might think otherwise.

I
wish I could insert this info a few pages back, but I’ll settle for tacking it
on here. I stumbled across some more information on what we were calling the “capped”
style of air tube. This
style was designed in 1938, and patented (2,204,372) in 1940. These 1950 pictures
show the three Daisy air tube assembly stations. (My wife believes they could
have splurged on more comfortable seats for the ladies!) It
would appear the shafts of the air tubes, and the caps, were pre-assembled
together before reaching this point, and from here these ladies would position
the body of the air tube on the cap for the final crimping action, making the
assembly complete. Hopefully the more shop-minded among us can explain what is going
on here, as I may be totally wrong in what I am looking at. It
wasn’t many years after this picture was taken that the air tube evolved into
the neoprene washer era and an entirely new air tube design began. |

I was a bit surprised as well, but in this first Variant the shot tube itself is a brass pipe. The shot tube cap is steel, as is the magazine (soldered together into one unit), but I think the brass-on-brass contact between air tube and shot tube when firing was better for wear. I have two photos in my files which show what I believe were brass air tubes, so I was ready for anything.
The first photo is an air tube from a Markham 2236, and the second photo is from Dave Alpert's photo collage. The third photo is the brass & steel shot tube. |
