I have an Akron 107 and a 103. Both generators are plugged and I have found no source of new or OEM ones. I am going to try the soak and heat procedure but in the meantime I have gotten a 1/16 IPT tap and die and I am going to use a 55 generator, remove the flare and fitting, then using the die cut a short thread on the end of it and install it in the lantern. I think that should work for now. Not original but practical.
Please let us know if the R55 works O.K., it may be too short. Straight replacements are available from www.oldcolemanparts.com Akron S Generator - R238
Michael I’m curious what a 1/16 IPT thread is? If it’s actual 1/16 NPT that will be much larger than the diameter of the generator.
Well, I'm not sure but 1/16 is the smallest NPT tap. The diameter of the thread is the same as a 10-32 but the thread is not the same. 1/16 NPT is 27 TPI so I ordered one and we shall see. I had also thought that I could get a piece of 1/8 brass tube and put a wick inside and get a tap like the thread on a Coleman r55 generator and use the jet off one of those and form a new generator like the s type. Just playing around right now. I will find out soon enough when the tap and die come.
@Michael Brewster They are going to be to large. Generators are made from tubing not pipe. A pipe thread is a nominal size in that the 1/16" will be larger both OD (0.313" actually) and ID.
You're right. The thread is 10-40 so that takes care of the bottom end, now I need to make a jet on the lathe and thread that into the top and bend the shape and I think that will work. Do you know the number size of the orifice in a r55 jet?
Michael A Coleman R55 is marked Q, 0.008“ diameter orifice. Unless you have some high precision Lathe you are going to have some difficulty. There’s a reason why those drills are sold 10 at a time. There are fellows on the CCF making generators out of cunifer aka copper nickel tubing. Might be easiest to thread your tubing for a Coleman orifice.
You're are probably right. I have access to a good lathe but it will be difficult. Where can one buy just the r55 tip?
Ocp has the q99 gas tip(gt1) which should be the same, now you could always buy the cheap 603 generators and salvage the tip and innards.
I may have figured this out. I ordered some brass tubing that a very short piece can be used to slip over the tubing and solder a 55-generator tip to my tubing that will form my ess generator. It could also be done to an old ess generator which would allow it to be temporarily straightened and cleaned by now having a removable tip. What do you think? I hope I am clear on this. When I do it, I will post a picture.
