Here are a couple of posts from the ArtMetal mail list plus an excellant project design supplied by George Carlson for a shop built stand.
A reference is made here about a shop built stand for a small horizontal bandsaw. George Carlson has generously allowed us to refer to his site and view these plans that he has drawn up.

This looks like a very good project that will yield excellent
results. I'm sure that it is well thought out and kinks removed.
These guys are mostly machinists and the like.
Although I have not built this stand & pump for my small saw
as of yet, I have added a coolant pump to my big saw. The
results are smoother cutting and a greatly increased blade
life. I use a water soluble oil that can be mixed as much as
20:1. (which like the $13. bi-metal blades, also comes from
Tyler Tool, 601-876-2145 )
Be sure to focus your attention on what you are doing when
using a band saw. Check & double check that your workpiece
is securely locked in the vice or vise. You can easily break teeth
off of even the very best blades if the workpiece slips. You should
always lift the blade off of the piece to be cut BEFORE turning
on the saw. If you are cutting a long drop off, you should support
the drop with an adjustable stand. Squirt some light oil on the
rollers and guides every couple of days. Keep the blade tension
quite tight. At the end of the workday be sure that the saw is in the
down position and motor is un-plugged, to keep little hands attached
to the arms to which they belong. The small saws don't have blade
guards, so be EXTREMELY careful when using them in the vertical
position. Wear gloves because the workpiece can heat up quite
unexpectedly. Hold the workpiece with vice grips, tongs, push stick,
what-have-you, whenever possible.
If you are cutting a short piece, ( i.e.: 1" off of a 3" long piece) block
the empty side of the vice (vise) with a small piece of the same
diameter stock.
The rule-of-thumb for teeth per inch (tpi) is to have two teeth in
contact with the workpiece at all times. That means don't try to cut
thin emt tubing with a 6 tpi blade. you will jam the saw and break off
teeth . Just FOCUS and be very careful and you will have a great tool.
It should go without saying, but I'll say it anyway,

May I suggest that you make another modification? If you were to add a
double jet of coolant just after the blade exits the rear set of blade
guides, you could throw away that ridiculous chip brush. I added this to
my 7x12 saw, kept the orifices at about 1/16" for more velocity, and my
blade life took a major jump. By getting rid of chips in the teeth, you
are cutting cleaner and the teeth last longer. It runs off of the same
pump and the pump has more than enough capacity.
I also added a spin-on oil filter that the coolant goes through after
leaving the pump, and before going to the nozzles.
