That Altmann arm actually does have all of the requirements for a basic unipivot tonearm, as crude as it looks.
From there on up, it is just refinement.
It will play the record.
Of course, there is a world of difference between that Altmann, and a Graham 2.2, but the Altmann works and is cheap. If you are interested in tonearm design, it could be a fun project to make.
Another fun project, with an air-bearing design, is the Paul Loudegaard linear tracking air bearing tonearm design, that many tonearm "fiddlers" have tried. It also works and has some excellent design attributes. You can search it out on the web very easily with Google.
