Did you ever cut anything before?

3.5hp would require at least a 2.5kVa transformer, which unless you're wiring is huge, that transformer shown in the picture is alot nearer 150Va than 2500Va.
A 150Va could probably just about spin the router up with no load, but as soon as you put a load on the router, either the fuse for the transformer should blow (if it's sized correctly), or the transformer will overheat and fail.
