Just popped in to read through your thread and do what I do best. Harrangue people! (Yeah, I realize you do not know me but will let you know that it appears we have a similar sense of humor. Mine may be darker or you may simply hide yours better. :p )
Everything is quute aesthetically pleasing, well, except the guy in your user pic! Seriosuly, though, it all turned out very nice. It will be interesting to follow along and see how well the painted MDF holds up. Speaking of that, what primer/paint did you use?
I'm not surprised that you changed the "final" canopy design. How do you access the tank? (Maybe the dumb queation of the day.) Is the far side panel on a long piano hinge? Or will you just break out the sledgehammer every time you need access!
How about snapping some pics of the control(s) section? Also some of the sump. I'm curious to see what all is "under the hood" and how it is run. Plus, since you self-admittedly said you would have liked to have documented the build better, this will give you good reason to start doing that now.
That is all for now but I may have more requests in the near future!
Wishing you and your wife a New Year filled with good health and happiness!
