I actually had quite a bit of experience on Giddings and Lewis machining center back in the late 80's and early 90's, that was on a five axis metal working machine. When I started seeing the CNC stuff on the legacy I wanted one, but about the time they were modifying the manual LOM's I was in the middle of my big 3.5 year house rebuilding project.
Once the house was done I sat back for a few years and built up my wood shop, picking up some pretty nice equipment and built Murphy beds and lot's of end and night tables. I always thought about that CNC stuff, and got close to considering the Legacy Maverick CNC 4x8. $26k was a nit much, but I thought about all the things I could do with it . . . And then several trips to the Philippines kind of took on a life of its own. š Now that Teresita is here and I have a supportive wife, ( Uh, the trips to the Philippines had a benefit of epic proportions.) I am now thinking about all those fun things again, even finally putting together my New (old) model 1200 LOM. I have been doing some "stuff" on the 1200, but to be honest, my ultra technical experience on the Giddings & Lewis spoiled me. I was able to edit g code, manually entering lines into the programs directly on the machine console. Back then the computer generated code was "sent" from an old DOS 6.1 operating system program called Genesis over network lines to the machine console. From there I would pick it up and modify if and when needed, which it very often did. I could even manually produce simple programs for surfacing and making straight cuts of many types. This machine also had a 16 place tool holder, and of course, who wouldn't like to have that on a Legacy? I noted the comment on the router shifting a bit on the LOM when changing directions. I thought maybe I didn't assemble things quite right because I see that also. In addition, I see some play in the outer rails when making certain movements on the x and y axis cuts. I also have noted some drifting on the z axis, I have the upgrade, and I now am beginning to think that maybe the old plunge router sled might be more efficient for what I have been doing thus far on the 1200. JOE: you have the CNC package still in boxes? What would that go for it you sold it to someone who might think about using it? I have been thinking about modifying two LOM's to make a wide setup to flatten boards and to do cut outs on plywood sheets. Just rambling thoughts at this point. I have seen mills near here for a pretty los price that might make it feasible. Maybe. So, to CNC or not to CNC, that is A question. I too have a computer IT background. I spent 25 years in IT, first with building and implementing units and specializing in Windows operating systems, then software, then Network systems. And then 20 years of Government Public Safety System implementation and administration. During all that time, when I saw the CNC era come into play at Legacy, my heart was there. I visited John at Legacy in Utah four times during business trips, even spending an hour with Tracy as he was working on a project with the Maverick. Hmmm. I still think about it . . As I enjoy my retirement.
