I need a square lock nut for my Rikon mini lathe 70-100. The last post for these was in 2009 and I was unable to reply so I sent a PM and have not received answer.
I will try and contact Johnnycnc. The original locknut is not bad, I just want to upgrade to the square type. BTW, Rikon has very good customer support. They actually have a live person you can talk to and understand.
I'm sorry I have been out of these..
time has just not permitted me to get more made.
There are plans for more later, but I know that doesn't help you now.
Wait for Johnny to have more. I have the Rikon and the one for the Jet works great. It is certainly better locking then the round original that comes with the lathe.
