#1 Magnetic antiskate
It’s about 30 years since I last built a tonearm. So I have been searching the web for inspiration and came across this https://www.diyaudio.com/forums/analogu ... tions.html. Has anyone played with anything like this, I had a Decca unipivot decades ago - which I dismantled to understand it better. As the Morsiani arm is meant to be up there with the best.

I haven't but that's a great thread with Morsiani actually there in person.
I know James D put the Morsiani tonearm at the top of the tree.
I'll have a bit more of a read later.

I understand the principle... what I cannot fathom is what the structure ( looks flimsy) which goes over the tonearm is for, i thought at first it housed the magnets but clearly not, see http://www.morsiani.it/

this intrigued me years ago, albeit after I'd given up vinyl......
but I always thought the second pair of magnets were in the top of the cup, and as the arm progressed towards the centre the effect of the magnets diminished.........
but I never got the real answer

I see what you mean. Having the website still available is very decent of him - but it could do with a couple more pictures. I shall however save the pages and the diagrams he put in that thread, for future reference.

Those two columns up either side of the arm, have different capping pieces on on various guises of his arms, some are plastic some aluminium. I wonder it to align arm, or a transport thing - don’t think it’s anything to do with the antiskate or the normal function of the arm. I am trying to figure how to include this antiskate approach into what from an engineering perspective I think is the best unipivot design.... that I can hopefully clone... the audiomecana Septum. https://www.tnt-audio.com/sorgenti/belladonna3_e.html.
I already have an aluminium billet ready to machine the arm from, just need to get the 4th axis working on the cnc router.

Never heard of the septum arm, just had a look at it.
I do like the azimuth arrangement, very simple

Whilst investigating magnetic anti-skate, I came across this. Interesting bearing arrangement. Easy to replicate, the duo pivots seem to have all the advantages of a unipivot without the disadvantages. Something to consider if I decide to build a new arm.
Torn between something simple like this and the Dynavector arms... the engineer in me likes the later...
