E' possibile non utilizzare gli antiwobble, ma se le barre trapezoidali sono un pò storte come nel mio caso, conviene effettuare l'installazione degli antiwobble come in foto;
I TOP_Z e DOWN_Z utilizzano cuscinetti "688Z" ; per i TOP si potrebbero utilizzare dei cuscinetti flangiati KFL08, ma consiglio di utilizzare i cuscinetti come sopra.
Con i coupler flessibili lavora bene, e non esiste alcun segno di wobble o altro errore meccanico.
Per fissare bulloni delle trapezie, utilizzare delle viti per legno 3,5x10.
And 'you can not use antiwobble, but if trapezoidal bars are a little twisted like me, you should carry out the installation of antiwobble as in the picture;
The TOP_Z and DOWN_Z use "688Z" bearings; for TOP you might be using the KFL08 flanged bearings, but I recommend using the bearings as described above.
With flexible coupler works well, and there is no sign of wobble or other mechanical error.
To fix bolts of acme, use screws 3,5x10 for wood. Print Settings
