Matt, do u have any pics of ur rack???
I think my next project will be to build one for neonate bloods seeing that theres no way in he!! they will feel secure in the enclosures i have built....
Is it really that simple as it seems?
As for wood...im no expert but as linds said many ppl use plywood....however i think that malamine is the nicest way to go for tall slender racks....just attach a towel or something of that sort to the bottom...so u can slide it around...however..i live in an apartment with only hardwood floors...so probably wouldn't work if u have carpet.....WOW..i'm kinda gettin off topic

Uhhhh.....k..i got nothin else to say
