This was a well written and very thorough how to guide that tool a lot of dedication and I commend you for it. I am contemplating taking on this endeavor on behalf of my adult son who was gracious enough to allow me to use his machine and I am now a huge fan, just in time for the battery to wear out. Still debating if I will attempt but know for sure I would not even begin.to consider it without your guide. Thank you for such a selfless endeavor!
