Machining a 4mm radius on the 9x20 lathe

[tjbaggins]

Depends on the rad of the tool it's double the the rad in pos

the "titty" on the face is eliminated by machining .125 past the X0, and of course the tool needs to be on the center-line or .01 below.

you need a new insert and a higher feed that stud in the middle is beacause the height of your tool is wrong

Hey Good work! I find this amusing.  I work with two lathes; one has a 50" chuck diameter and the other has a 78" diameter.

Hi, awesome, what's the Lathe ?

[satyvirjasra]

That machine....it spins around like 20-21 times a second!

Nice, the 9x20 was my other choice when I bought my little Sherline lathe. That spindle motor sounds... authoritative. Thanks for sharing.

[plutominusone]

im thinking about getting that lathe is it a decent buy?

How are you controlling the spindle speed? I can hear it ramping up and down, are you using a big servo motor or a VFD? Looks good!
