Hello Brian,
I have the Super Major, which is the version with the dove-tailed vertical column, as opposed (I think) to the round column of the GH Major. I have been very pleased with it in general. The only issues are that the gearing can be a bit noisy (experiment with oils) and also when the fine down feed quill drive is engaged, the main hand levers at the side can tend to jump back into mesh and this causes the quill to then retract to the top. I solved this by hooking a light elastic band around the levers when in fine quill feed.
I fitted DROs to the table on X and Y travels, and also to the quill Z axis. invaluable enhancement! My machine has the powered X travel and this motor too is a bit noisy. I make sure the gearing is well greased and not too tight in mesh.
Overall, a good machine. My previous Warco Minor was a good 'un too.
Regards, Mick
