I don't agree with trashing somebody's ingenuity. There is a thread on this web site (referenced from another site) where a couple of people trash some kids radiator cover that his father made for his quad and it seemed a little mean spirited. However, if, when you post pictures of your work, you are expecting a bunch of that-a-boys and no criticism, then you might not want to post pictures.
I will now step down from my soap box and except all criticism for what I have just posted.
Tahnk you and good day!
