Unhappy with the inconvenience of the Takahashi NJP threaded counterweight shaft? Tired of weights with chipped paint? Would you prefer stainless steel counterweights with a smooth counterweight shaft? You can now replace your NJP counterweight shaft with a stainless steel shaft of the same dia. as used on the Astro-Physics 900 and 1200 mounts. This mount will allow you to use my stainless steel weights, or those from Astro-Physics.
No modification is needed on the mount. You simply unscrew the Takahashi shaft and screw mine on in its place. You can go back to the NJP shaft any time. So, no problem with selling your mount in the future.
The counterweight shaft is solid stainless steel, 1.875" dia. x 18" long. It comes with a machined stainless steel safety washer.
