I have wondered about getting in touch with the new owners of Myford
about creating a Myford-based CNC lathe for the modern model engineer.

Andy,
I like the looks of that 300 model. I sort of feel the same way about
my new lathe. It is just big enough to get something done yet takes up less
space. That and the layout is similar to the Asian 12x36 that I used to
have. Really looking forward to having my first CNC lathe in the shop

I didn't disparage all Chinese machines, just the smallest lathes. I'm
sure there is plenty to disparage about some of the larger machines as
well. They could certainly do better, but at the pri

Without a doubt. They can land Jade Rabbits on the Moon after all.
However, that doesn't mean that they always do. Any more than the
likes of Portass and Zyto, makers of cheap lathes in the UK used to
do.

I agree here.
Connect to a solid base causing the base to become a part of the machine.
Don't disparage the Chinese machines. My experience is as follows.
Machine is a Mighty Viper 5BC bridge mill.
She Hong in Taiwan built the machine. Mighty imported the machine without a
