finally I am finding some time again to work on on my machine. Basically, it’s just drawing in some cables and a few touches here and there. Just discovered the forum thread on the new center assembly, but having printed all parts, specially also toolholders for the Makita router and others, I’ll start workin with the oldschool version.
And here is my question: I just cut the z-thread rod to length. I have a long coupler nut (M8), and some springs that are all pretty stiff and pretty long. Now, if I put it all together and compress the spring just so far that there is still no realizable increase in friction, the set is too long for the nut lock, it wouldn’t even hold the bottom nut.
Would it make much difference to use just two ordinary nuts, separated by the shortest effective spring I can select here? Shortening the working thread length between nut and rod would simultaneously reduce the friction, I guess, due to the smaller surface area involved. Or am I wrong there?
So, to boil it down: Should I rather
[ ] look for a very short spring and use the long coupler nut and a short one,
[ ] combine two short nuts with an existing spring?
Thanks for your advice!
