Same problem, the Az bearing still has no support for side thrust (nor does the alt bearing). It all depends on whether you want a platform to mount a dobsonian on or build an equatorial mounted telescope out of dobsonian components.
I could build an equatorial base to mount a DOB OTA as I have a proper workshop with all the necessary facilities but it would still not be a trully practical project. In time and effort it would cost as much as Paramount.
A dobsonian mount is a great, cheap and simple method of mounting a telescope for practical viewing. But as a basis for an equatorial mounted telescope it is not practical. By the time you beef up the rotating axes you may as well have built or bought a proper mount.
