There remained a few soda siphons that I was unable to fix and when I visited Peter of www.kafko.nl I took these with me for him to have a look at them.
A few were easily fixed with rubber seals Peter had in his collection, but one was more difficult. To get to the tiny piston with the old used-up seals, the handle / trigger needed to come off and the little screw had no intention of letting go after being stuck in the head of the siphon for maybe fifty years.
The picture story (which ends with the soda siphon in full glory) starts when Peter uses a drill to make a hole through the screw, about as wide as the screw itself:
|Drilling out the stubborn screw|
|Getting a grip on the siphon head to create a new thread|
|Creating the new thread|
|Taking out the old worn rubber seal off the piston top|
|Slipping the piston back in|
|Still need to find a new / vintage screw that will fit the thread|
|Found one! Only the head is just a little too big.|
|Making the head just a little smaller|
|Perfect fit again!|
|Getting ready to saw off the other end of the screw.|
|Ready to test!|
|Screwing in the CO2 capsule|
|It works again, and no leaks! A 50 year old sodaa siphon reborn|
