redtop03's 360 gallon plywood adventure

I been experimenting with making these nozzles,I tried 2 different designs,here are some pics

the strait out ones work best but the others were easier to make,I tried to use air line tubing to show the suction on the vents,but it's not to clear,they are pulling air through the tubing and I'm guessing they are pulling water as well.....

they probably don't compare to the store bought accelerators,but they do disperse the flow some :D

here's how I made them,first I used my bench grinder to cut the slots

after I cut the slots,I used a round file and cleaned them up some
 
here's how I made the other nozzles

I first started my drill into the pipe straight until it went through,then I slanted the drill until the holes were slanted like in the pic....this was an old scrap 90 degree elbow that I'd cut out of a previous plumbing job,I first took my miter saw and cut the elbow in half,creating a 45 degree cut,there is enough lip left on it to direct the flow and I think thats why it's not working as good as the other design
 
have you tried doing (2) large openings like the DIY loc-line penductors thread i showed ya??

i think the problem you might be having is those small holes can't suck in as much water. the water flowing thru the pvc will create a lower pressure, so water will be forced into the holes & out the end. maybe take a large drill bit near where the end fitting mates up to the pvc pipe & drill (4) large holes straight thru (the bigger the better) & see what it does that way

there was a thread on RC on building them out of a few pvc fittings, but finding the search function on here is a joke. it was similar to this link i found on the interwebz:

I think you are right...I'm gonna try a few other ideas,I ran out of extra fittings,and don't feel like running to Lowes right now :D
 
i always seem to buy too many fittings when i goto lowes & then have a box of crap to take back, but always forget to do so LOL

i think you can take a bigger drill bit to the angled drilled ones to see how they work & then get new fittings for final mock-up :D

thats a good idea,I'll try that next....I've got a headache right now,I've stared at this screen for too long :lol:

been sitting here listening to Melev's Reefcast all day,thats some funny stuff,might be why my head hurts :lol:
 
staring a fishies seems to clear my head.....guess it would be nice to have a tank right now. i took down & sold all mine & have found the eerie sound of silence i don't care for.....i need the sound of trickling water :(

if I'm sitting in front of the tank,I'm usually very relaxed,I spend too much time on the 'puter though.....but I learn something new just about every time I'm on RC :D

you could set up 1 of those table fountains,you'd get the trickle sound,but it wouldn't be the same :)

you live close enough to glass cages you could have a super nice tank anytime you want it,money providing....I was gonna drive down there and get my glass,but found a glass co. a lot closer to me and they were only $12 more than glass cages...I couldn't drive that distance for the difference :D
 
yeah, having GC so close is great. the 29 in my build thread was from them. also several cut pieces of glass & acrylic for various projects came from them. i broke down & sold everything cause i'm probably moving before the end of the year & didn't feel like putting it all in storage.....just gives me a reason to plan my next one perfectly in my head. even thought i'd LOVE to have something like you or matt's monsters, i don't forsee it anytime soon

if I'd had a full basement,I'd built mine bigger but I really didn't have enough room for what I did build,I was planning mine smaller,I screwed up on my measuring and made it bigger :D....I had it planned to be 30" front to back I made it 36",I had it over half way built before I realized that I mess up,it was too late then :lol:
 
on those fittings that your trying....try a 1" to 1.25" slip fitting on the end....your flow will be broader i bet...those holes on the back will add flow from behind the fitting so you 1000 or so gph out of one will be....now this is a guess...any where from 1500 to 2000 from that one area....so wider the better! i think those fittings are less than a buck...worth a shot!?!?

yep,that was my next idea,I was thinking 1" to 1.5"but I'll try both,the 1.25" would look better :D

that would be nice if it increases that much,I like to tinker with stuff like this,but if I had an original to look at up close,it would be easier to figure out a better plan of attack :lol:
 
That's some pretty creative plumbing. I think you're on the right track. If it is sucking air through the tube, the it's definitely sucking water through.

I think customcolor might be on to something. Maybe use a larger than your pipe size coupling to build the the area that you've been drilling. It might give you more area to suck water in.
 
the great thing about these is that there is no real input needed. the flowing water creates a pressure differential (lower on the inside) & the higher pressure outside is "forcing" the water in to the lower pressure...where it meats the flowing water that forces it out w/ the water already flowing.

the reason water doesn't come shooting out the sides where the holes are is cause once water "joins" together, water tension helps to keep it together until something breaks it apart....think water coming out a garden hose. the water at the end is still together for a distance till it is broken apart....in this case by a combination of gravity & the air it is hitting

the narrowing of the water inside can be done to create even more pressure differential (since it increases the internal flow)....but it's not absolutely necessary. that is why just cutting the sides out as in the loc-line DIY thread do what they do.....uses the existing pressure differential created inside the loc-line by the flowing water & just gives a point of input for the lower pressure water outside the loc-line

i got another one for ya but i have to wait till the lights come on....i dont know why i didnt think of this one when i took the other pic....i have had it on my tank for a few months and its working well and there is only like 400-500gph going through it (i have 2 out puts to the tank and this is on only one) but acts like 2 times more flow atleast...
 
Man, I am so lost with this plumbing crap...I dont even look forward to working on my plumbing...hey, way to go Willie, thanks! :lol:
