NasoHutt's 180 build

After a 7 year break from the hobby I'm jumping back in. I have finally settled on an AGA 180 with corner overflows. I'm going to have a basement sump located in a small fish-room I've built under the stairs leading down to the basement. In order to save room down there, I'll probably have the tank drain into a 40B under the stand that houses the skimmer, from there it will drain down into the sump.

I've elected to build my own stand as none of the commercially built ones meet my taste. Woodworking being another hobby of mine I decided it shouldn't be a problem. After reviewing the many 2x DIY stands here and looking over the commercially built ones I became conflicted. I have a tendency to overbuild and thus the DIY stands made from 2x fit the bill over the seemingly sparse construction of the commercial stands. I rarely use anything but solid wood for my various projects. Solid lumber has one specific flaw though with regard to its dementional instability. In furniture construction this is compensated for in various ways. In an application such as this, where the immediate environment is humid and warm this problem is important to recognize. So I've decided to combine the two worlds and use plywood like the commercial stands and sufficiently overbuild like most DIY's. The process I'm using also 'skins' the stand in one step, and the lack of 2x legs and supports intruding vertically into the inside on the stand yields a clean final product.

I'm using 3 sheets of 3/4" ply. 2 Birch and 1 QuarterSawn White Oak. The plan is to laminate three pieces of ply together to yield a thickness of 2.25". I will incorporate woodworking's strongest joint in the process, the mortise and tenon. I cut all pieces ahead of time to their final length except the outer portion of the legs, which were left oversize for ease during glue-up. The top rails and legs will essentially be 2.25"x6" and the bottom rails and vertical supports will be 2.25"x3".

Here is all the wood milled up and laid out for the front.

Here I have laid the oak face down and the birch over the bottom rail, you can see the gaps that will become the mortises.

The overhang on the end will become the tenons going into the legs.

Here is a shot with the longer middle piece for one of the braces that is acting as a tenon.

And a shot of the inside bottom rail completing the joinery.

Here is the inside of the completed back, the screws are strictly for ease of assembly and not structural at all. By using them I did not have to worry about clamping, and could go from one piece to the next.

Here's the bottom edge showing the completed through mortise and tenon on one of the supports on the bottom rail.

Here's a bottom corner, this is one of the legs still a little oversize that I will cut flush later. This is a blend of a lap joint and a mortise and tenon.

And the customary FTS.

180g is size. Great size.


I think so too. When I left the hobby I had a 360G and a 120G. The 360 was just to big. I enjoyed the 120, but always thought another 2' would be perfect.


I finished gluing up 4 sides last night, once I get them all cleaned up I can join them together. I'll post pics once that is done.

Making Progress....

Got the squeeze-out on the 4 sizes moderately cleaned up and then joined them together. I decided early on that I'd like to add depth on the corners so the doors will not seem to protrude out from the cabinet. I just joined the 4 sides together using butt joints which I will cover with solid quarter sawn white oak. I applied glue and then used three 5" lag bolts to fasten each of the sides together. I will add horizontal braces and a solid 3/4" ply bottom to keep it from racking. I have yet to decide about adding a ply top, if I do not I will add corner blocks near the top to further counter any tendency it may have to rack while moving. I need to decide this because I want to add a 3-4" ledge around the top of the stand with corbels supporting it. I'd like the plastic trim to sit under the grade of the ledge so that it is at least partially hidden. My reservation about doing so is the difficulty it will create in lowering the tank into the stand. Hopefully someone will chime in on how that can be done without simply 'dropping' the tank into the hole.

Here are more progress pics...

For my last glass tank that had trim I cut out the trim +1/4" on the lip of the stand and slid the tank in from the back. Make sense? I made a channel for the plastic to sit in but when the tank was in place you couldn't look down and see it. Just make sure to add a bit for ease and warp. Nothing worse than a big tank stuck to a stand.

I had thought about sliding it in from the back, but making a channel so the trim couldn't even be seen from the top would be really clean. Getting it in there would be intense as the tank weighs somewhere around 300lbs.

That leads me to another question. Has anyone that has their tank over hardwood flooring put felt feet or felt strips on the bottom of the stand or just set it directly on the floor? If I slide the aquarium in from the back, I'll need to either slide the tank and stand back against the wall or pick the entire assembly up and move it against the wall......:eek1:
 
I would just use some sort of rubber casters so that you can somewhat slide the tank on the floor safely. I would just use old fashion man power for the placement and install sense you should only have to do it once. Beers and BBQ are popular around here for getting people to show up.
 
Some progress....

Some progress....

I have been chipping away at this slowly but surely. I've trimmed the stand and finished the doors. I'm ready to give everything a once over with the sander and start finishing. Here's some pics with the doors on closed and open.

Great work on the stand!
I went for a 180g and I am very satisfied, however IF I could do everything again I would have gone for something a little bit deeper such as 24" tall, 30" deep (back to front) and 72" long. I keep a lot of tangs and they really enjoy a lot of swimming space so it is important to have space behind the rock work as well as the front so they can swim all around and through the rock caves. The 24" deep did not leave a lot of sand space in the front. An extra 6" to a foot would have been perfect.

Keep on coming with more pictures!

Thats is some beautiful work! More pic!!

Thanks. I've been derailed a little, there's been some house work I've been neglecting that I've had to start so the tank is going sooooo slowly... I have made progress though. I've got the stand moved up stairs and should be putting the last coat of finish on the doors this coming week. Might have more pics next weekend.
 
Which glue did u use for the glue up?

I used 2 different glues. Where I needed a long open time I used a plastic resin glue like Gorilla Glue. For the pieces that go together quicker I used Tightbond III. I try to stick with Tightbond in everything I do because cleaning up squeeze-out is much easier! Just a tooth brush and water. The resin glue requires Acetone or Denatured Alcohol and it doesn't seen to come off completely so will then need to be sanded carefully before finishing.

Thanks! I wish I had the room. This one's going to TIGHT as it is!!!
 
Very impressive stand your workmanship is top notch. i recently put up a 180 and have been subscribing to 180 builds lately. tagging along. good luck!
 
Plus you already have the "beast" in your hand. It was just a consideration. I'll be tagging along, I really enjoy seeing people "ideas at work" and yours, I feel, is going to be a good build.
 
Update...

Update...

The tank is progressing slowly and is currently on hold until next spring. (hopefully) We are expecting our second child so between time and money the tank gets whatever is left over. No problem, I want this to be a quality build all the way so its necessary. I'm about 1/2 through a DIY 25H AIO that I decided to tinker with in the meantime, mainly to test some DIY LED lighting I'm working on. Here's a pic of the completed stand and tank minus hardware. Sorry for the weird angle, the room is my home office and the layout doesn't lend itself to a FTS with the stand in it head on. Anyway, with any luck I'll get the nursery finished in time to work on the canopy before the due date. So my spring target can be realized.
