各位前備 謝謝大伙的指教 及 Minnow的回達
看過了很多舊的文張 及討論 But still do not understand, especially the words in all the discussion are so small, and I have a very difficult hard time reading it.
I believee we all have the same intereting, when we all see something new or beautiful DIY equipment, we all want to make one. don't we? and this is my intention why I want to make one.
thank you all
