Progress
Alright folks, I finally made a little more progress! I finally sold my motorcycle (ugghh) and got some cash to build the stand and a get a few last things.
I haven't started on the stand still (I know, I know!), but I did pick up a great skimmer to replace the T5000 shorty I was going to use, and I thought I'd post some pics. I'll post this in the DIY section, too...
I picked up this custom skimmer body from dgil for $300 delivered by him personally to my doorstep. While it didn't come drilled or with a pump, I thought it was well worth it. It's a clone pretty much of a deltec, made with 1/4" cast acrylic. The inner diameter is 8", so it's 8 1/2" all around, and 28" tall from top to bottom.

I went back and forth about what pump to use, but finally settled on the OR3700 I already had instead of shelling out $300 more for an Eheim NW pump.
First I had to tackle the problem of converting the German metric fittings to NPT sizes we use here in the states. spazz has a great thread about how to do this, which can be found
HERE .
However, I did not want to cut off the fittings in case I end up wanting to use the pump for the T5000 if this skimmer doesn't work out...
So here's what I did:
The intake of the OR3700 actually threads quite nicely onto a 1" union that I had. However, I wanted to go down to 3/4" piping (because that's what my uniseals were, and I figured I could go up in size if necessary...). So I simply took the collar from a 3/4" union and widened the opening with a file here in order to accept the 1" female side of the union:

I also had to shave the female side down a bit here to fit inside the threads of the collar:

Next, I was able to simply use the male side of a 3/4" union on the other end. I drilled a whole for the venturi on this side of the union, so this part stays with the skimmer when the pump comes off:

Here is the venturi air fitting I made out of a 1/4" X 1/4" JG adaptor:

Sorry for the blurry picture. I will probably experiment with the venturi design some before I'm through, but this produced promising preliminary results.
Next, I had to use the collar of the metric fitting for the output and do the same thing to convert the male end to a 3/4" union. To do this, I had to destroy the long 90 that comes with the skimmer (but can be replaced for a few bucks). It came out nicely:

After fitting the pipes and drilling the holes and installing the uniseals and then the pump, this is what I came up with:

And finally, a fresh saltwater test:

I just ordered an airflow meter to check out its draw, and will put it on a kilowatt, too, but I think it's pretty promising! Now, on to the stand!
