#Aquarium stand weight support - ideas for design appricated too.

I'm currently making a stand for two 70 liters aquariums probably 100kg each. The beams for the table will be 4.5x9.5 cm of pine tree wood. What do you think? any ideas? My idea is to build drawers in the left side of the table, where the distance between the beams are shorter and the bigger hole would be doors.

Also ideas on to how to make it all look nice and rustic, is appreciated.

I might put some cross bracing in the back to help support the weight better.

Other than that. Sounds like it'll look pretty diy, which isn't a look many people arround this discord care for. But someone else might have some ideas for making it look rustic

here's another version

I’m not sure how to extrapolate how you’re assembling from the model

quaint canopy
#

this new image is two wood rectangles supported by 6 beams

storm shell
#

How pieces are joined is critical to assessment

quaint canopy
#

I would do it with screws

storm shell
#

If it’s assembled with butted pieces that are screwed together I would be concerned about it’s load potential

quaint canopy
#

How would I go on about making it more safe ?

storm shell
#

Mechanical wooden connections. Laps, mortise and tenon, dadoes

I believe half laps are largely considered to be the most approachable

quaint canopy
#

Okay I assume this is what half laps are

storm shell
#

That is one example, yes

quaint canopy
#

How would you recommend to set this up with half laps

storm shell
#

You use them where your pieces meet at 90 degree angles

quaint canopy
#

so here for an example ?

#

cut an indent

#

that the rectancle can rest on

#

Something this important to hold a huge amount of water might be a bit ambitious if your knowledge level needs explanation on the application of a lap joint

quaint canopy
#

That's how I roll lol

#

Learning by doing

#

Take the time to add all the joints into your 3D model so you can visualize and think about the direction of force applied to them

quaint canopy
#

good idea

hidden kernel
#

And when you actually make the thing, test its strength thoroughly with something that has less catastrophic potential than life-form filled water and glass

quaint canopy
#

Some people do it like this too

hidden kernel
#

Yea those look like half lap joints connecting the legs to the bottom and top assemblies

storm shell
#

That’s functionally a lap joint

quaint canopy
#

i see

#

alright going to try a new 3d model

#

think those details out, then i will be back

stark nimbus
#

That right there is your half lap, see how the wood is supported by more wood and not just with screws

#

I would be concerned with this if horizontal force were to ever be applied

#

Though if we're placed in a corner of a room it would probably be fine

storm shell
#

This version would also be unforgiving to gaps

quaint canopy
#

unforgiving to gaps ?

#

currently refhinking the design

stark nimbus
quaint canopy
#

so let's take the joint under the table at one of the corners

#

this would be how they should be assembled

#

with half a peice sticking out so the middle part can be pushed between ?

#

Poorly cut is more of a execution thing then a plan thing

quaint canopy
#

yeah i'm probably going to poorly cut everything lol

#

which is why i want to make simple cuts haha

stark nimbus
#

Yeah lol.

I'd say. Make some things that will have less weight on them First to get a feel for how this construction style works.

A Night stand and or computer desk for example.

Then come back to this project with the lessons you've learned

quaint canopy
#

i did make this one

stark nimbus
#

I'm not familiar with those plates your using instead of traditional joinery. So I don't know how well they would work as you increase the weight from a bigger aquarium.

From what I see here there's very little stopping it from falling sideways if anything gets off of 90° because the whole thing will lever apart.

That being said a few peices of plywood screwed onto the back and sides would probably be enough to keep the whole thing rigid.

quaint canopy
#

so a big piece of plywood behind my current project would be a good idea

#

the stand i made there is very sturdy

#

not moving

#

also i fastened it to the wall

#

for extra security

stark nimbus
#

Yes because it would resist "racking" or horizontal force that would cause a collapse.

Securing the stand to the studs of the house would probably also be good enough (but I'd be dubious about just the drywall though)

this ended up being the final design
