Anyone know of a good way to mix blend your own gases usinga separate Argon & CO2 bottles? I really don't want to spend 1500 bucks or more for a gas mixer and would rather just make something on my own that might work well.

Don't waste your time. It will never be consistent without a mixer.
Really not worth it when Argon / CO2 mixtures are pretty much the cheapest gas there is.
Go pick up a 75/25 or whatever you want to use. Mixing without a mixer will be nothing but a headache.
Maybe you can try something like what Jody demonstrates with the "Y" fitting noted here:

Will that do it?
her is a home made one http://weldingweb.com/showthread.php?t=45450
Basically I already have the pure argon & co2 bottles and not looking to purchase another one with the combined mixed gases to save on space. Also it's a lot of trouble on changing the tanks for each type metal. It would be nice to have the adjustability to make your own mixtures so I would like to find an internal picture or diagram of a two or three gas mixer unit to make my own version. They're basically just flow control valves with regulators plumbed together from what I can tell. I don't believe the two flow control valves joint together with a Y-fitting would work too well without another flow control valve at the end line.
I wonder if they make those Western valves with three inputs for the addition of some helium mixture.
Now it is not what you are asking... but when I went in for my TIG gas... Straight Argon, I just swapped a 75/25 for straight Argon. No extra charge. I own the tanks. The guy just wanted to confirm what gas I wanted.
I know in your situation you may not want to turn in a tank or swap for a small job... Just tossing it out there.
just buy 2 valves and stack them then you end up with 3 inlets and 1 outlet or use a pex manifold with valves Attachment 7495
