What size L is it? I still have some L chucks and I think an Jacob's Flex collet chuck for a lathe that I no longer own.
It's an L1
I believe 30 taper has the same taper angle as R8, just more of it. I'd be surprised if an Acra was anything other than those, but someone also could have swapped the spindle or had it reground.
The 30 taper has dogs on the face to take the force, correct?
This spindle doesn't have those. It literally looks like it would be an R9, if that were a thing.
