Why this aversion to drilling holes in machines ?
If the factory had done this then that's OK ? End of the day they are tools to be used to the best of the OWNERS ability, not worry about resale price or cosmetics.
Who's to say the factory fitted attachmnets cannot be improved on to any extent ?
Nice work Gray, I also fitted a set to my Y axis on the old POS Bridgy I had, still have to make some for this new machine even though both have DRO's fitted. It's quicker, more positive and less prone to error
