Kowa SLR Mount

[Budgie]

Hi I have a Kowa TSN 602 and need to attach a DSLR

I have located a tube that has a mail T mount thread at one end which, using an adapter I have been able to mount my camera body to, what I need now is an adapter ring that would allow me to screw the female T mount thread of the tube, on to the scopes mail thread which is a slightly smaller thread.

Any help greatly received
