A DRO will pay for itself in a month or less due to increased production and improved quality, especially when center to center of dowel holes is tight. Yeah I ran mills & lathes W/O DRO's for at least that much time and ran lathes W/O a Travel Dial for years. Amazing things happen when one keeps up with technology. BTW, I rarely use HSS turning tools these days.

Anybody ever use a jog function on the mill? I've used it on my lathe but I'm not sure how useful it would be on a mill. I can eliminate a switch and the associated wiring if it' not going to be useful.

Might be handy for tapping Ed
Free advice is worth exactly what you payed for it.

I agree with Greg.

Yup, I thought of that after posting. It stays in the design.

I've had it on machines, and even my current lathe has a spindle jog button.
In sum total I have used them exactly ZERO times, and I do power tapping on both machines. A jog button for feed on a mill...indispensable.

I consider a "rapid" feed button on the mill to be indispensable to quickly re-position the table, but a jog button? I've always believed a "jog" button refers to short and/or s-l-o-w movements.  Is there an advantage of using a jog button over using the crank handles somehow for slow deliberate table movements? Or is it that "jog button" is just a generic term in the industry? I just want to know if there is a trick of the trade I'm missing here.  I actually like having the jog button on my lathe and use it often. When the spindle is in it's lower speeds it's easier to roll the chuck over with the jog button vs. fighting the gear ratios to roll the chuck by hand, or kicking it in/out of gear to get a good look at the surface of a part ALL the way round. I've used it to rewind the "clock" springs on my mill quill feed, and small engine recoil starters, spooling wire, string, etc. 101 uses...

The jog button on the mill is for the spindle, not for table movement. At least on my mill. Oh, and I use the jog button on the lathe quite often. Ed |
