I found it quite easy to resize the drawings after a little while, just open the files in autocad and select everything and scale it 25.4 bigger and take some measurements from the eDrawings files to be sure everything is corrected.
Im making some other modifications like taking away the holes and things made to make the machine to weigh less. More weight more stabillity and it will save some time cutting and making the parts.
