Joep,
I think you can solved the problem by adding v.s welding a distance holder , it's easy to produce .
It looks you already have a long trow CNC (bleu) cylinder.
the problem is that you now have to much free play .
when you look on Pantera place you find a sample .
Ik heb geen watts app, of internet op mijn telefoon alleen thuis een computer
waar woon je ?
gr,
Simon
