  • Hi svdr, thanks for your comment! I was on vacation, so I totally missed out on it, sorry.

    In another post on my blog I described in detail (with pictures), how I rebuild the stand of my drill to fit the mirror. Unfortunately YouTube does not accept Links in comments, but you can find it on my blog in category "Werkzeug".

  • Very instructive! We had this problem on how to dril a central hole with a small drill stand. You solved this most 'elegant' by simply putting the drill stand on top of the blank!
