Thanks for the compliments guys.
The planter has now been stained a cedar colour as per my dear wife's wishes. It looks a bit better but shows the errors more clearly because of contrasting pieces. No pictures yet as the weather turned sour and it is more like fall today than summer so the planter is drying in the garage.
Interestingly, one of the problems was by design though not intended to be a problem. I found that the holes for the axle were unusually large and not really attractive so I decided to make them smaller and fit more closely with the diameter of the axle. It all looked good until I started to assemble the frame at the front. As I drew the frame into a "V" in the front, the axle became tighter in the holes. I then realized why the original holes were so large. Fortunately the wheel still turns but it is a tighter fit than I would like. Smaller holes should have been drilled at an angle so that the axle goes straight through, not at an angle to the frame holes. I never was good with angles

and that was the reason for some of my other frustrations.
I kept one of each piece from the original planter to make more as I'm told again that my daughters might want one. Hopefully the next one will go more smoothly, but I'm not counting on it.
If anyone is interested, I might be able to draw the pieces and measurements on paper but I'm not sure if I would have time before we leave on our two week anniversary trip next Thursday. I still have to make a bird house before then.
Have fun
John
