just thought you all might get a kick out of my amateurish, diy DRO system. not exactly something new or revolutionary, not even really
my idea. if nothing else, ya'll might just get a few laughs out of it.
the dro on the mill is just a 4" digital scale i got from shars the other day. i think i ought to make some kind of chip guard for it. the mill was made by "northern illinois machinists" and i cant find any info on this manufacturer at all. its a pretty simple little machine, and works fairly well. kinda similar to some of the really small barker bench mills i have seen. although the work envelope on it is pretty tiny.
as you can tell, the lathe version is just a set of cheap 1" dial indicators. one mounted on a carriage stop i made, the other on a piece of 80/20 aluminum extrusion that i mounted onto the back of the carriage so that i could adjust its position of the y axis relative to the cross slide. helps compensate for the massive amount of backlash this thing has. its from 1942, and seems like it got used a bit.
thanks for reading.
