Well done for getting it drilled out - there's always a way round these things. In a recent thread of mine regarding a 'home made record player', I had to drill out a broken off pin in the spindle of a Garrard speed change control.

I've just collected an old HMV 145 cabinet gramophone from a friend of a friend tonight. It's consigned to the garage for the time being, but I took some pictures of it when I got it out of the back of the car earlier on. Now I've looked at the pictures, I can see what model of gramophone your arm and sound box have come from. If you look, you can see how close the arm mounting point on yours is to the turntable platter compared with the greater distance on my HMV, thus accounting for that very bad tracking error on yours.
