Nervis1,
wanna change your nick to destitute1?
Oh well, now you've spent the money, you can buy all kinds of 3 phase equipment now, and they can all share the convertor. I know, I went through that stage years ago, myself. I was glad to finally get on real 3 phase service though, because the starting characteristics of a motor on a convertor are not quite as good as "on the line", because the phase angles are not equal from a convertor.
BTW, is your electrical service beefy enough to handle the start load of that motor?
