Thanks for ideas and the praise guys
I would be hesitant to make it a static fixture like a flower pot. I spent quite a bit of design effort to make this a functional cart that can actually be used. I suspect, being pine it would not survive long exposed outdoors anyway.
Scott's idea with the tradeshow cart is interesting. So far I have not participated in such shows but may do that later when I retire.
Have not thought about that yet. I suspect even being "used" I won't make that many miles and if needed the 1" oak dowel that serves as an axle can be replaced.
I used the Teak Oil (Watco brand) because I ran out of the Danish Oil and the clear stain. But AFAIK Teak Oil is anyway only a marketing name for slightly different formulated Danish Oil. It is however more amber colored which was O.K. for this purpose since the pine will darken yellow/amber anyway in short time.
