What sort of blades are we looking for here. If yor machine is what I think it is, (but i'm not exactly sure what it is. Is it a small bandmill??) it uses standard band resaw blades. Have a look in the yellow pages for saw blade macufacturers, give them a ring with your blade spec, and they should be able to weld something up to length for you. Resaw blades range from around 2" width and go up to over 10" width. I think your machine will take a blade around 3" width.
Let us know a bit more about your machine and we may be able to help. If youre in the Chesterfield / Sheffield area I may be able to help even more.
PS please let me know if your machine is what I think it is, or if i've dropped off the cliff completely. :lol:
