i did some additional tests to get this tube cleaning process optimized:
the fiberglass stick with shrink-on tube is not that super effective and efficient because you need a new stick every 4 to 5 pins.
so i made sticks out of different materials:
from left to right:
- a stick filled with sand and super glue (hard as rock)
- fiberglass with super glue
- stick with moddeling clay
none of this sticks had a good cleaning effect, and also cleaning with a stick remains a sequential process so wasting time.
to come to an end, i made a toolset based on another idea i had to clean all pins at once, so here is my final solution i will use to clean my tubes:
the toolset consists of
- plain sand (from a beach volleyball field nearby)
- a foam rubber disk 2 mm thick
- a wood disk 1.1 cm thick
i dried the sand in my convection oven and used a sieve to remove little stones and other particles (the sand shown in the picture is not cleaned).
i had the wood disks 'on stock' to make y-splits for headphones, but here i used a shaping tool to shape a ring into the wood just of the size that the tube pins will fit (depth 8mm).
i pressed the tube pins onto the foam rubber disk then making small holes where the impressions of the pins were.
here is a closer view where you also can see the pins of an uncleaned tube (you will see the cleaning result - a prove of concept would be nice i thought - later):
how to use the tools:
put the foam rubber disk over the tube pins to protect the tube during the cleaning process.
fill the shaped ring of the wood disk with sand.
press the pins into the shaped ring filled with sand.
- hold the wood disk in one hand and the tube in the other hand
- slighty pressing them together the foam rubber disk also prevents the sand from falling out of the shaped ring
- rotating the wood disk by turning one hand clockwise and the other hand counter-clockwise (and vice versa) will clean all pins at once!
cleaning result (i used a stop watch here to have comparable results that can be verified):
this is the cleaning result of
- 60 seconds of cleaning with sand
- additional 60 seconds of cleaning with sand saturated with alcohol
- cleaning the pins with compressed air to remove sand particles (3 seconds )
showing the uncleaned tube posted above now cleaned:
i am sure that the result can further be improved by also using for example that cleaning powder used for stainless steel kitchen parts.
that's all! and have a nice and now short cleaning time!
P.S. the sample tube shown is a german Telefunken one, so i just used ethanole as alcohol, for uk tubes i strongly recommend Glenfiddich Single Malt Whisky Special Selection :-)
