Hi, I’m writing from Italy. Is there a way to talk to you more directly, like on Instagram or by email? I just bought the Hitachi P20SA2 planer and I have a couple of questions. Let me know if that’s possible. My email is francescorepele773@gmail.com — please help me! 
Hello and thanks so much for all the info. In the shopping list doesn’t take me to the correct measurements in Ali express. Question ? In the spacing screw what M did u set (m3 or M4 ). How long can it be ? Such as M3 15 +6 ?
I got the shaft collar 10x16x8 but I don’t know if the thread is m3 or m4 ?
The ball what is the outside diameter and inner ?
I got the second hand p20sa2 today in the mail .
Thanks again for the great work to modify the planer
AliExpress as mentioned.
