****************** I've used them years ago, I couldn't remember the name. Thanks.

except for that pesky programming?

That seems like negative thinking to me. Positive thinking would be more like "how do I get these welds done so it isn't a bottleneck?". A weld could need only a second or two and cost only the energy it takes.

Lacking foolishness, a rarity for me, I hired a CNC company to build and program the controls. They also had a couple of my engineers in the loop from the get-go so they know the system inside and out and will be able to modify the program. It's fairly simple, with four pneumatic circuits and two hydraulic circuits. And, they did it all for $2.5k I'll post pix in a few weeks.

Good one Don - surely there must be a few small engineering shops that would be eager to do this sort of job....or has it got so bad in your country that a simple thing like this needs a CNC equipped factory to make a simple part.....

Yabut I got 9 punch presses and no projection welder.

Tap the hole and "Locktite" in a threaded rod. I just did this on a chisel sharpening fixture I built. ...lew...

Or thread it in and tack it.

Cheers! Rich

Good idea! (please no disclaimers about how it isn't really YOUR idea.)

How about a for-example? I.e., stud & hole sizes, drill press speed, how long does it take.

Thanks, Bob

I would expect that there are a few small CNC equipped engineering shops that could do this easily...
