Does anyone have experience installing glass scale 2 or 3 axis dro on a BP type milling machine. My mill is a BP chinese clone by Birmingham 3hp 3ph vari speed 9x49" knee mill. I have been using this machine for about 8 years now and it performs quite well but I think all of the hype I've read about DROs has caused me to purchase one, but the instructions that came with it are not very explicit and don't give any info as to what to lookout for tips/tricks etc. for installing the dro.

Any help would be greatly appreciated. TIA, tlangy.
