Roger, Kelly sometimes has to "give up" his computer to a child who has a penchant for re-building them and experimenting. Sometimes it takes a day or three to answer. He is a heckuva guy, though, and you can't go wrong with him.
If need be, PM me and I'll give you his phone number.
That said, I have an "in stock" list from him as of 3/18/04 and the widest 1/4" 1084 he has is in stock is 1.25".
If all else fails, I'd try Admiral 1080 (wince). They have large sizes of 1084 listed, but most is now 1080. Buxton has tested it and it performs in his opinion equivalent to 1084, I believe. Maybe he'll chime in here.
