A while back I bought a computer hutch that I am using as an electronics hutch. My plans for it involve raising the whole thing up about 25 inches or so, and using a high bar stool with it so I can stand and work if I wanted to.
I thought it would be best if I ‘put it together’ using Google Sketchup. The joints are a little more complex then they need to be, as I like to build things where the fasteners don’t bear the load, they just hold everything together. Idealy, the screws and such just keep it from wobbling around, and the project sits together by itself.
Here is my pile of cut wood. I realized after I had cut everything, I read a demension out of sketchup as 16 inches, when it really said 1.6 feet. Oohps. Now I have to go get a new 2×4 and recut those 4 peices. Bummer.
As promised, here are some more details on the construction of my Home Made CO2 Reactor. This CO2 Reactor is made from a couple of aquarium siphons, and an airline tubing splice connector.
I drilled a hole in the top Siphon Cap the same size as the airline tubing splice connector. I chose to drill the hole as close to the edge of the ridged plastic in hopes that I can give the connection some mechanical strength. I left as much room as I could so there would be enough surface area to make a watertight connection.
Here I am drilling a hole through the plastic siphon hose after I had slipped it back onto the end of the siphon cap. This hole is the same size as the inside of the plastic airline splice peice. I wanted the rubbery hose to form a tight seal around the airline splice.
After a lot of cleaning of the burs in the hose and pushing hard, I finally got the splice to fit inside the hole.
I made an improvised clamp system out of 3 nylon zip ties to hold this whole area toghether. This area leaked a little bit, so I ended up wrapping another zip tie around the elbow of the airline tubing and the siphon tube, to press the airline tubing more tightly against the rubbery hose in hopes of creating a better seal. The water leak seems to have stopped.
In looking at how the completed arrangement thing functions, I may move the airline tubing down into the larger part of the siphon tube. With the airline tubing fitting where it currently is in the hose, a lot of water preasure is trying to make the whole thing leak. I think by moving the airline fitting out of the hose, and into the larger tube, where there is mostly gas as opposed to moving water, I can eleminate the chance of this fitting creating a leak. I also think that I would be able be able to change out one of my Yeast & Sugar CO2 bottles without water trying to flow down the airline tubes when the whole thing is mounted higher then the water level on the fish tank.
