Yes Dan, got an angle grinder  that makes short work of it :-D

Hood

Ah.. OK. It just looked so good that I thought you acquired a Plasma CNC and didn't tell us Wink

Very nice, Hood! Do you cut your sheet metal parts yourself?

Looks very good, Steve!

Looks you're having great time, Hood Smiley Only drawback is setting up the jaws for each diameter is a PITA on a hydraulic chuck Sad

The disadvantage of Geneva type ATCs is them being rather slow. It drivers one crazy watching the turret stopping at each position when setting up tools.

Amazing, Tweakie! Must admit it took me a while and at first I even tried to figure what went wrong with that Gcode Grin

Yes, Steve, I was talking about the Bridgeport right angle head attachment.

Regarding the backlash in rigid tapping, compensating it in software should work great. I do rigid tapping on a lathe that has about 0.1mm backlash on the Z and compensate it in Mach and it works very well.

Like your solution! Especially the fact it turned out relatively inexpensive. There are such heads ready available, but are very expensive.

By the way, don't see a reason for preloading the bearings if all it's going to is drilling. I think there would be much more backlash in the gears that could be a problem for rigid tapping.

OK, I see now. Thanks. Although I would have to check to be sure, but I think I could get here a Delta PLC for at least half that price.

Hi Hood,

Have a question for you. I know you usually use PLCs on your machines. So it made me wonder why were you after a controller with lots of I/O and being 24V? Wouldn't an ESS/PLC combination make up a much cheaper solution? And possibly lots more I/O?

Dan
