The thing is, that a rack-box (ala the last Tim's post) or a rolling wood-box/stand is not that complicated to build, I'd say it's somewhat on the basic skills or so

, BUT!!!!!!! it looks and is simple, while in practice it's a pain in the neck to do especially if you do not have power tools (say, you do), then you may not have space to work - it's a big mess, but , say you have space and tools, then go for it, still pain in the as&

, that is so if building is not your common activity.
What I would do , being in your shoe (well, as a thought) - is this: I'd get some currently available generic rolling studio rack and build something around it (reinforce it with extra rails or add on wood sidings etc) if you feel like you want it or maybe it seems like something has to be done so it can handle the job for the reel-to-reel machine you've got.
I've found these items on ebay:
http://cgi.ebay.com/NEW-12-9-SPACE-ROLLING-STUDIO-RACK-STAND-69-99_W0QQitemZ190066224711 - this one actually looks pretty good as is (?) what do you think? it sais up to 110lb,
the other is cheaper and looks pretty skinny ..heh heh, but can be used as base/parts for the project (maybe) - link:

I have no clue about that seller nor I took time investigating, just posting as example. those racks maybe are available somewhere else.
MF has its cheap thing too, the one we've already "dismissed" in the past ... link:
http://www.musiciansfriend.com/product/Musicians-Friend-Mixer-Rack-Stand?sku=450821 , again, it looks like it can be used for the project.
Building things from scratch? - HUH! - righteous thing to do. So, grab the ruler, pen, a napkin, your drink and start designing. Post pics then
