Hi, W@ayne,

?

My pleasure... though I was down in the shop installing the lathe carriage DRO this afternoon (see pics below) and I realized that I didn't include DROs in the list of larger items.

?

Technically, you don't really need them.? But the way the ELS system works, you "tell" it where you want to go to by moving the cutting tool to that point and pressing a button to store the location.? The question is, how do you know where the desired point is?

I avoided getting DROs for the lathe for years, because I felt I didn't really need them.? I got by with a calibrated stop, or by using my compound aligned with the carriage.? With the stop, I would touch the first surface I planned to cut, lock the carriage, position the stop against the carriage, lock the body of the stop in place, back off the carriage, and then turn the calibrated portion of the stop the desired distance.? It only gave me about 3/4 of an inch (19 mm) but was accurate to around .003-.004 inches.? I used a similar technique with the compound.? But I removed the compound and replaced it with a solid plate for more rigidity, and the stop only works if the last bit of the distance is fed manually, so... DROs.

(Huh... the system gave me the error "SyntaxError: Unexpected end of JSON input" when I tried to insert the photos.? I tried the photos that I posted this morning and got the same error.? So something is hinky, but I have attached the photos instead of inserting them.)
