Thanks,
@MountaineerMiner for your assessment. I don't typically consider machines over 4,000 lbs as that is the most that I can move without calling in the riggers. The reason this machine is so attractive is it's a half mile from my shop, and we can move it with my friends' forklift. He purchased it a number of years ago from his employer when they upgraded their shop, so he's quite familiar with its history. It also comes with a newly rebuilt spindle.
I understand that the electronics can be quite a hassle, especially with these older machines, which brings me to why my friend offered this to me in the first place. I mentioned that I was looking for a Bridgeport-type machine to do a CNC conversion, and asked if he knew of any in the area. With this in mind, I'm approaching this from the standpoint that if I can't get the current electronics to work without too much trouble, I'll be removing them and putting in aftermarket controllers, etc.
From what I've read, these Mori Seiki are 100x better than many of the current import machines of similar capability, so it seems like it would be a good candidate for a CNC 'resto-mod'.
