As in a lot of plans I made them to fit my needs. This one was no different. I love Anna and her site. Sometimes things are not always clear. With simple knowledge you can solve most of the problems. I made this version for my 5 year old niece for Christmas. I decided to use 1x12 in place of the plywood . It was easier to work with and made it much stronger With the solid wood I think I lost 1/4 inch in height. I also had extra 1x3 boards I used them for bottom shelf. For the dials I used what I had. I used my hole saw and filled in center with filler. It was cheaper than buying a dowel. I think it is easier to mount the shelf before you put the sides on. Top grill I stayed with 1x2 I thought it looked much vetter that 1x4 board. I finished it off with castors I think that put the icing on the cate and made it even better. She loved it.
