    Thanks, John! I like that follow rest (traveling steady rest). Carriage really does always seem to speed up when close to the end of the thread! Nice tip on setting drive gear clearance.

    Happy New Year. I enjoy seeing all your videos. In this I really drew attention, that contrary to what my dad taught me, you tools to thread the counterpoint and not towards the head around. Just wanted to share this with you. Congratulations on your talent and thanks for sharing. A hug from Mexico.

    Nicely done! I picked up that you have a handle on the nut that holds down your tool post. That is a great idea (no wrench needed). Sounds like a project I will be making. Thanks for the tip....

    Don't know what all the fuss is about, seems perfectly understandable to me... Thanks for showing this. That insert with the "depth stop" built in is very clever. I'd not seen one before. I wonder if ball screws could be done similarly, but with a different insert?

    Nice video, what material are you using in the acme rod?

    Hi All I know about the material is that it was 316 stainless I was given it so that is what I used EN8 would have been my choice if I was buying it You should give it a go on your myford some fantastic work has been turned out on "old myfords" regards John

    Hello There, noticed you have a frequency converter on this lathe. Are you aware of the related cooling problems ?. I mean at low speed the cooling fan on the motor gets less efficient while heat production goes up. To avoid that you remove the normal fan and put on a constant running electric cooling fan, you can get those made for the purpose but some ducting and a normal fan will do as well.

    Really depends on how long the motor's running for. You may be thinking in this video the motor is running slow. It is not. Motor is running a reasonably normal speed and lathe gearing is giving the slow spindle RPM - which also means there's very little load on the motor to generate heat.

    Thats an insert tool, wouldnt that wanna go faster so the heat leaves with the chips and dont go into the insert and thus making it expand, catch and break it...

    I would think in a production enviroment it would be run much faster Just playing at home nice and slow is my method John

    Could do with that 626 at the moment for the P800, need to raise the vice up 9 1/2" off bed so head clears when swung 90 degrees. Doin me ed in.

    he'll be fine with light cuts like that. I am surprised the machine is rigid enough to run inserts. I am surprised to see that insert too. Light cuts and slow speeds I guess it will last forever. In production the cuts would be much deeper and much faster and yes would have issues at that speed-or so I am told.
