Rotating monitor construction *Project finished*

Im sorry I think I got your project confused with the one csa3d is doing..
Thats a good idea on the plastic rollers. I think I will try that if the bearings dont work.
We have some material at work that looks like that. I might get a piece of scrap and make some rollers.
BTW, you did an excellant job on your cabinet...

If you were asking me (I was confused as well), then I used a 2" by 5/16" threads. I converted 8mm to inches using google, then turned 5/16" into a decimal, then subtracted the two numbers.. and determined the margin of difference would affect the project very little.
Now also remember my monitor will be a lot more horizontal then vertical. If I was going to mount this vertically, I think I would probably used a longer bolt and thicker wood, so that tilt would be minimized a lot more. I'm not sure my 1" bearing is a adequate enough for a vertical mount without some sort of secondary balance, be that rollers, felt pads, or whatever.

Opps.... :D

I have hooked my isolator board and H drive to my computer I plan to use for my project.
I have seen some behavior on bootup that is different from my desktop computer.
As best I can tell:
While the machine is booting, all outputs come on (I was expecting that), then all go off except for pin 2, which appears to stay on for a few more seconds.
This is highly undesirable for my project.
I am gathering parts to build a test box so I can actually see what all outputs are doing.
Right now with my isolator board I can only watch pins 2,3, 5 and 6.
Do all computers act differently with the printer port on bootup?
This could be either very interesting or very aggravating.
I have developed a small program that will allow you to turn on and off the printer port outputs, and monitor the inputs.
I also have a PWM process built in if you want to play with speed control.
Here is a screenshot, PM if you would like to try it out.

There are some registry hacks for windoews that will keep it from trying to autodetect anything on the Parallel port ( I googled them, found them, used them and lost them again) If your Bios is doing it there is little you can do, other than use some sort of timed relay that kills the outputs till the pc reaches a certain state...
