Shuttle is a great example. Just think of its task / # of parts / complexity / budget. The risk of catastrophic failure before the first one even flew was estimated at .7% (7 out of 1000 flights) and to date, the program has met that design objective.JPG40504 wrote:Gee!

P.S. Not sure the shuttle program is a 'good' example!

But can you image the complexity of the "beta test program".mickyd wrote:Shuttle is a great example. Just think of its task / # of parts / complexity / budget.

I worked on a program (as Program Manager during the design phase and then as Engineering Manager during the manufacturing phase) that was responsible for nuclear survivability of a Satellite Communications System in orbit.
Launch day at the pad was our last chance to correct mistakes. Once that day became history, all I could do was pray that I had done my job as I had been trained to do it. There were NO do overs]entire career on that one program[/U] - carrying it from cradle to grave.

This is an extension of post #47
As said earlier, the work that Wes and Jim did to put an end to my one issue with the PowerPro didn't work as planned on my machine. I did adjust the lower belt by moving the motor away from the axillary spindle. Then re-adjusted the eccentric. Now the lower belt is very tight. I can almost play a tune on it. Gave the exact separation distance between the two motor mounts to Wes. I wanted to make sure they were exact from side to side, and they are (within 1 or 2 thousandths). (.222" separation).
Wes put the original calibration back on my machine and I will be content for a while, bandsawing with the 3 3/4" faceplate on the aux. spindle. With it - my PowerPro is perfect! Shopsmith will continue to try to duplicate my machine and find a computerized fix. Yes, mine is unique, I think!
Oh, by the way, when I was just messing with the programmed settings in the embedded chart, I found that the setting for the Pro Planer puts the motor in reverse! Wes said that is normal as users of the machine mounted model would now put the planer on the spindle side of the headstock. Wow! that's a change!

Interesting, that was one of the first things I checked in the programmed settings, I thought they might have set it to reverse direction for sharpening mode with the strip sander but no.
I'm glad you are getting the bugs ironed out and expect we will all benefit form your experience. I hope to get a little time in this weekend putting my machine through the paces.

Got the PowerPro back....
As you may know from my previous posts, my PowerPro upgrade had some Q/A problems when it went out the door. It was missing the motor mounts, had not been tapped for the ground screw, and then I had some problems with the speed sensor wires breaking. Because of the multiple problems, ShopSmith picked up the entire headstock around the 6th, checked it out and fixed all the problems, then sent it back to me. I just got it back today.
Plugged it in, turned it on, and man, does it run smooth!
I'll play with it some more over the next few days, but I wanted to let everyone know that ShopSmith took good care of me. Thanks, ShopSmith!

Breaking In
Been enjoying the saw and jointer setup for while. Smooth, quiet, etc.
Alas, in switching to disc sand modus, the jointer necessarily got disconnected, of course. On starting the disc sander, a minor rumble issued froth wile it ramped up speed. Upon touching the spinning disc to workpiece, the dreaded (and almost forgotten) ruckus from Dirty Ernies Washtub Band came bursting into the shop from the innards of the seemingly suffering PPro.
Dang.
Amazing how fast the fun runs away when "stuff" happens.

Oops.
Don't want to leave a bad impression, about the noise and all. I went ahead and used the sanding disc, cacophony be danged, and can't say-- didn't see-- that the speed/load corrections had any effect on the workpiece at all. But effect on me, well, you'd think I could deal with it a little better-- after all, I survive listening to Greta Van Sufferin on Fox every now and then, so obviously I do have a tolerance for truly horrible noises.
Anaway, the sanding went ok, and then switching to drill press mode is like therapy. I mean, when was the last time you forgot to turn off the Shopsmith when you were finished, because you couldn't hardly hear it?
Maybe this is just more "breaking in", as the PPro gets run thru it's various capabilities.
