Ha, ha, nice work. You guys are killing me. Go big or stay at home! You could be on Tim Taylor's home improvement show if it was still on. My little two and a half footer with 8 watt air pump and AquaClear 301 powerhead is not worthy...

Nice dark nog, wait a couple weeks for that baby to really get going, I get that much in about 4 hours on the 750, waste collector gets emptied daily and the smell is horrible.
|
we found the type of wood (lime-tree) in a lumber place and is really cheaper making them yourself...
We can make 12 air stone with a 4$ plank!!!! |
2 months since the skimmer is in action!
We really think it's working great! our hait algae problems seems to end, the algae is dying and disolving! The polyps extension is amazing! I think this old technology is quit "soft" on the water... compare to using a needle wheel or other pomp that are hard on water... |
I don't know how I missed this thread when it came up but I make my own wooden airstones out of basswood. They are 2"X2"X7" with a 7/8" dia. bore.
I screw in a nylon fitting from TSC stores with a 3/8" barb for the air line which is supplied with some of the air from a Pondmaster AP100 linear compressor. The main skimmer has a foot cube receptor at the top but the other four just have a cereal container for the receptor. MY SKIMMER PAGE |
Nice work there rayjay, I like your take on the collection cup, a little different than the conventional setup around the outside of the reaction chamber. Since you've resurrected this thread, it might be a good time to present a few photos of my DIY basswood air stones.
Here's my first attempt after being in use for many months (lost track but it was still working quite well). I put a rock inside before assembly to weigh it down. http://public.blu.livefilestore.com/...42e.JPG?psid=1 Assembly of the new one, in service now. Since the basswood plank I have is relatively thin, I need to fuse two sections together for each of the four sides to get a good sized diffuser out of the deal http://public.blu.livefilestore.com/...49e.JPG?psid=1 As you can see here, I don't use precision tools, just a hand saw & miter box, so I don't always get an even cut. A bit of sanding takes care of that and it's really not that critical due to the large surface area you get from the box design http://public.blu.livefilestore.com/...50e.JPG?psid=1 And the new one, ready to go. Not quite as clunky at the top & bottom as my first effort and I used basswood for the ends, whereas with the first one I just used some pine I had laying around. I find there's a bit of a break in period with these DIY diffusers and they actually get better with age, to a point... http://public.blu.livefilestore.com/...51e.JPG?psid=1 |
My stones are solid.
I use a 7/8" boring bit with extension on it for depth. I ground a little off each side to make the hole just under the 7/8". Then I tap the top part using a piece of pipe with 7/8" OD thread, I think it's 3/4" pipe where I cut long narrow "v" groves along the length of the threading and then squeezed the ends together so now the threads have a slight taper but still have a gap. I screwed the other end of the pipe into a "t" for the same dia. pipe and shove a large screwdriver through the "t" when using it as a tap for the hole in the basswood. I use 3/8" nylon firm tubing inside the skimmer, fastened to the stone with 3/8" vinyl type air line, and the same vinyl air line from the top end of the skimmer to the linear compressor. I tried to get mileage out of trimmings left over after making a batch of stones, gluing together like yours appears to be, but it came apart in only a few days. I guess I didn't use the right glue. |
