bigboij very nice, love the shelves on the doors, i think i might "borrow" your idea, and attach a basket/shelve to my stand's door will help clean up the mess of chems/foods/etc off the floor of my stand

Hoppy That really looks great! Obviously you have done lots of woodworking projects before. Now, I can't wait to see how it looks with the finish coats on it, as well as with the light hood.

lauraleellbp That's gorgeous!

jesse7876 Latest update:

I got the "skins" put on the doors, and have started installing the trim. The outside of the doors is 1/4" birch plywood, as it seemed the most flexible of the plywoods, and I chose a couple pieces that were already slightly bowed.
I had to soak the trim boards for a while to get them a little more pliable to bend. Those pieces on the top are glued with liquid nails.

jesse7876 Well, I got the basics of the first door complete and got it to fitup correctly on the stand. I put a couple "stops" on the two bottom ribs so that they can be used as shelves for storage.

That doesn't let you easily raise and lower the light to adjust the light intensity, but it would be relatively easy to make.
Thanks!

That's a great idea, although I want to build a system that's very sleek, and looks basically like a curved box with a tank in the middle. Also, I want all the light contained so that it doesn't shine out the back or out the top during the evening. This way the tank itself will really glow.

I do appreciate your feedback, Hoppy.

WeedCali Whoa thats sick! My dad wanted to do this with my stand when we built it.

jesse7876 I've got some more progress...

Added the vertical front support and put the two sides on. I also built one of the curved doors.
I think it's mostly self-explanatory from the pics.

You could solve the twisting problem with an axle connecting one of the rear pivots, so both linkages have to move together. In any case, it is a very interesting device to design and build, even if it doesn't work quite as well as you want. I hope you try it, because I want to see someone succeed with this better than I did.
Great idea Hoppy! As I'm not real good with working on steel, and mostly have wood tools, I'm going to try to use parts available.

I'm thinking of having the back of the hood supported by slides (drawer slides) so that it can move vertically up and down. Then, I'll have two struts mounted at an angle from the back of the stand towards the center of the hood. This way, it would move vertically, but have the struts supporting the weight.

Of course, I need to do some tests to make sure something like this will work correctly.

jesse7876 I took a class in college on designing four-bar linkages. Basically, you dictate the motion you desire, and go from there to create the specific links.
I may have to go look through my old material.

Thanks for the comments! I'm going to skim the stand with a flexible thin plywood and paint it with a darker textured spraypaint. My goal is to capture the eye at the tank, and not at the stand.

I was considering using a spring-loaded stay hinge similar to what you would see on a toy chest.
I do really like your idea though! Is there anything like that available or pictures of something someone has done?
I could create a 4-bar linkage as you suggest that would lift out, up, and back so that it is raised directly above the tank when I need to do maintenance.

ryndisher I agree stand looks great so far.
