Yeah, that's one way. It's the faster way and most often used in bike shops BITD.
I prefer to remove the drive side locknut and leave the axle in, so I can use a QR skewer to secure the tool. Not technically necessary with splined removers, but Phil removers are extinct, and I don't want to trash mine. I guess I should point out that if I use my Phil tool, it goes over the locknuts so none of that is necessary, but if I was using a thicker old Atom or park remover, I'd do it that way just because there's less chance of slippage. I've (knock on wood) never actually met a freewheel I couldn't get off. (and please don't send my your rusty stuck wheels, Bike forumites!!!

)
To the OP: the obvious thing to do at this point is remove locknut using either my suggestion or Kontact's, and see if the tool fits. Could be hanging up on the locknuts in a non visible way.
