Last week I finally got around to adding an azimuth fine tuning controller to my diy equatorial wedge, which is little more than a bunch of M6 fittings fixed to both the wedge body and one of the bolts that attaches wedge to the tripod. I only just got around to it as I the original bolts I got for the tripod were not long enough (there were in fact flush to the tripod body), so I had to go to a specialist trade shop again to get the mtyhical UNC thread bolts and nuts.
When the tripod bolts are loosened I can then use the wing nuts on the side mounted azimuth control to make slight adjustments to the azimuth angle when attempting zero in on Polaris while doing a 'wedge align' as a part of the equatorial alignment setup; there is enough give on the size of the bolt holes on the wedge to allow some rotational movement.
Hopefully this works out better than the disastrous results that come with picking up the entire gear and trying to shift it slightly one way or the other!
Now I just need some clear skies... on a night that is not too cold please!
