I can't be the only one :/. A Ti Tip replacement just came in and it also gets stuck with a cap. These tips doesn't feel refined!. Got 3 different caps to try, all with the same issue
If you do not wish to send it back to Dynavap ,asking for a replacement one
then there's this quite easy fix .
Cut a strip of
xtra fine grit sandpaper (
2000 US grit /2500 EU grit ) ,
wide as the multi-threaded part ( "head" ) of the tip .
Fold it around the head of the tip. With your index and thumb fingers hold together both the strip's ends
and press your fingers against the tip's head ,"struggling " it with the sandpaper strip.
Then with your other free hand ,hold the tip from it's "neck" ( the finned part ) and start spinning back'n'forth or at one direction (whichever suits you). Do about 10 cycles and then clean the tip with
a wet soft cloth (microfiber is best ) or some cotton .Test-fit the cap .If still it gets stuck repeat the procedure as many times ,until you achieve the wished fitting.
Tips:
- Sandpaper lightly the "lip" of the tip's "head" and it's three notches.
Sometimes there are tiny burrs there.
-Wet the sandpaper tip for the last finishing passes ,
to give your tip's head a more "shinny" and smooth surface finish.
-when you finish ,use a cotton ear bud ,wet with ISO and clean both the inner and outer
surfaces and cavities of the tip.
-Caution : Do not use any other grit than
2000 US grit /2500 EU grit ,as you're going to remove more material than needed and the tolerances between the cap and the tip are pretty tight .
You want to remove as less material possible ,while reaching for your given goal.
Spend some more time and be patient and treat (sandpaper) your tip with care .
A great final result is going to be your reward .
Cheers.
