I modified the width of the shelves and as you can see from the variable height of my garage one side was made higher.
I used some scrap wook so I was able to cut expenses by about 25 dollars. The total cost was 50 dollars not including the nails. Although time is money. It took me one day to draw up the modified design, get prices and get the wood and then another day to put it together. With what I saved by doing it myself I could have made more working and buying a premade unit. However with this said, it would not be my personal accomplishment and modified to my unique needs. Besides, I had fun doing it.
Thanks for your info. It was very clear and simple. Debbie
