Last week I got the staircase up and rolling. I needed to lengthen the base at the arrow just like the handle earlier. 8 Bar Xylophone Bars A great source of Xylophone Bars for the Marble Machine! Only $7.99 8 Bar Xylophone Bars
	The 6 pages of plans were a great aid however I found that much improvising is necessary to to get from point "A" to point "B"! My parimeter gutter was too low so I had to change the entrance to the staircase.
	The upper track is the end of the parameter gutter.I needed to remove stock "gracefully" so the marbles could get to the staircase. I used a 3/4" drum sander in my elec. drill and worked very slowly! The fix came out ok. I also changed the entrance to the stairs, attaching it with dowels at both ends.
