I finally got a 12x36 Chinese lathe and i`m about to pull the trigger on a taper attachment for it.

It replaces the feed screw in the cross slide. I am hoping it replaces it with a 10 TPI .100 per revolution screw and not the funky .125 per revolution screw that this machine has. Anyone know for sure?

This is the kit i`m looking at: https://www.grizzly.com/products/Grizzly-Taper-Attachment-Kit-for-G4002-G4003-G4003G/T10556

Should work on any of these Chinese 12x36's lathes from the past 20-30 years.

I believe if it did, the instruction manual would make mention of it.

Looks like from the Grizzly photo it's 0.100" per turn or 10 tpi. The only thing I'd be worried about is the gear on the shaft that meshes with your apron for power feeding. Don't know if they are the same modular pitch and number of teeth on the gears. Push comes to shove, you may need to Frankenstein the Grizzly and stock parts to get it working. Not unheard up and naturally a lot easier to do if you have another lathe to use as the 12 x 36 will be torn down.

That makes sense, I could remake the gears if necessary.

I wasnt able to make it out in the pics, thanks.

Did you ever buy and install the Grizzly taper attachment? I bought one and am trying to install it on my G4003. I’m beginning to think the taper attachment is a complete piece of junk. I have some questions if you’re installing one. Thanks

I never did sorry, I'm leaning more toward making something instead ... but would love to see pics and know what you have encountered! We can make this thread all about it ...
