I'm in the same boat as you... As for shop talk, I've finally gotten around to installing the Z-Axis DRO scale on my mill, been sitting in the box for about 5 years.

By the way, anyone have any experience in repairing a burnt out light on a digital read out? An LED in my Y-Axis is out and I'm sick of my 8's looking like 6's

Ok this is not relevant to the conversaion going on right now but of you guys who have QCTP on your lathes. how often do you adjust the post? I have been having a back and forth between my dad and I he says you spin that sucker around all the time. I say set it up dead nuts square and let the tool do the work.

at our shop, we turn ours all the time

i'd say atleast 5-10 times a week (60 shop hours)

yes there are days we set it dead nut square and dont move it for awhile, but givin a little clearance on a bore, or turning it to stretch your X for bigger tools is always an easy solution

Mine gets moved all of the time to ensure proper tool alignment - such as when cutting tapers.

Here was my argument. CNC lathes don't adjust their tools from square and the inserts are made with that in mind. Now if you do a lot of work with HSS bits that you made your self yes I can see spinning it around to get a better angle at it. I know I used to do it that way, but now that I have a "real" lathe with mostly either brazed carbide or insert tooling I just keep it square I have all my tools setup in my DRO with offsets so that if I switch from cutting a diameter to cutting an oring grove I just change to that tool number and I know what diameter I am cutting with out needing to re zero. Of course I still check it from time to time but for the most part its done. If I swung my post around all the time I would have to re zero much more often and I think that kinda takes away from the point of have a QCTP and a DRO right?

turn QCTP
touch part off, zero the DRO
cut, measure, make money

I can deal with heat... open garage door insert fan.

But cold shops... no bueno machines run odd, material gets brittle, and hands get stiff.

Got you beat. My shop you would think was a bomb shelter except for the one window telling you it wasn't. Concrete all around

Now you're talking a different animal... Your other post didn't mention CNC
