Kitchen step stool

First off, I would like to thank Tony for the inspiration for this project (http://lumberjocks.com/projects/2176). Tony, I unashamedly copied you :)
I wanted to make a step stool that my wife could use to get to our upper kitchen cabinet shelves, and I felt this design fit the bill. I also wanted to do this without using any mechanical fasteners, so it is all mortise and tenon joints, except for the steps that I used biscuits on. The frame is poplar, and the seat and steps are maple. The challenge for me was cutting the mortises and tenons on the 7 degree slant for the two back legs. I cut a 7 degree wedge that I used on my tenoning jig to get the angle right for the top seat tenon, and then used the same wedge under the leg while I mortised for the side braces. Worked pretty well. (Any tips on how to do this differently would be appreciated)
I fashioned a paint “tent” out of a simple frame and plastic that set on my router table. I hooked up my dust collector to a large collection attachment that I taped some furnace filter material on to capture the paint. This seemed to work very well, and allowed me to spray both the latex on the frame, and the water based poly on the seat and steps. I purchased a low volume, low pressure sprayer from HF specifically for this project, and have to say it worked very well. It is made for handling latex paint, and operates at 30 psi, which kept the over spray to a minimum. I used my HPLV sprayer for the poly.
Comments and suggestions always appreciated. Thanks for looking.
