Yes, that's correct, but it's the only solution for the poor guys not having a northwaveOn your movie one can see that your solution works much better than the original setup. But the spring can't still be totaly compressed.
The RAB ist designed by Raichle to fit in the same boots that have this 4 or 5 position gliding system and not to obtain a high performance boot.
These boots have been looking more or less the same since the beginning. The RAB is really a pooooor performance of the Raichle engineers
The first version of the RAB had a smaller hole than the one you can buy now.Yes but it is not a problem of gliding or lubricant. It's a fundamental mecanical problem.
The RAB was silver and not black.
Everything was even worse with this silver RAB:
There was almost no clearance between the hole and the brass tube. Using a softer spring, I could move forward a little bit, but I couldn't move back again because it was blocked. Lubricant helped to release the blockig so that I could move back.This is why I recommended (in an other thread) to be sure to get the black RAB.
But you are right Jacques, with the new black RAB the limitations are pure mechanical and lubricant brings nothing. The smaller brass tube I used gives again a little more clearance, but the conceptual limitations remain.
Pokkis: You are right, my movie is made with much more force.
