I was never completely happy with the hand setup of the router. I have become particularly frustrated with the finish of pockets. So I bought a square spindle.
Tramming the Y axis was easy (I corrected more than 1 degree of tilt) but I found the screw travel in the X axis is too limited. I am at 0.4 degrees in the X axis and I cannot tighten the screws more.
In my quick test, the finish has improved dramatically (I think the Y axis made a big difference) but I’d like to improve the X axis. I am wonder whether I should swap for longer screws.
