Hey guys,
I have an Easson DRO kit coming in for my Rockford MV100 tomorrow afternoon.
@Brucepts, @Asm109 can you guys take pictures of the DRO scales as installed on your mills? I'm not sure how to correct for the casting draft on the column. It's *really* steep compared to the tolerances for a DRO scale mounting... Otherwise, I expect the X and Y axes to be pretty easy, but I'd appreciate the extra information that your scale setups would provide.
I ordered enough scales to install them on both the knee and the quill in addition to the table and saddle. Does anyone have any particular tips about installing a DRO on the quill? I know that it's possible at least on Bridgeports, but it seems to be infrequently discussed at best...
I'm debating between direct installation or doing something along the lines of what @Eddyde did in his thread with the carrier bars and spherical washers (https://www.hobby-machinist.com/threads/dro-install-on-mill-updated.46586). Does anyone have strong recommendations either way? Would it be appropriate to use heavy 80/20 extrusion for the carrier?
Thanks,
Will
Sidenote: I really, really wish I could do what Robin Renzetti (of Youtube and Instagram fame) did for mounting his scales inside his bridgeport table and knee to keep the chips and crap out of them. Unfortunately, if I actually finish rebuilding the original power feed with the parts I got from Bruce, I won't be able to fit the X axis scale around the cover plate that engages the keyed drive bushing with the drive worm. I'll just have to avoid using compressed air on my mill, but I was leaning that way already, given the cramped confines of my basement shop and lack of interest in picking up chips from the far corners.
