I'm restoring an older Taiwanese 12x36 lathe labeled King TD-45AA that is similar in appearance to most Taiwanese lathes from the period with differences in the apron design. One of its major problem areas is the feed mechanism. The worm is completely destroyed and the worm wheel has substantial wear. In my effort to procure a replacement, I bought a worm from Grizzly G9249 lathe. Unfortunately it didn't fit. Grizzly parts website doesn't list its specs or show photos, so I'm posting the measurements and photos here on the off chance it's helpful to someone.
Measurements (taken in mm, converted to inches)
RH, approx. 7.5 turns
Outside diameter: 31.4mm (1.24")
Width: 35mm (1.38")
Bore: 19.15mm (0.753")
Key seat width: 5mm (0.197")
Key seat depth 1.75mm (0.069") - approx.
