Marc`s DIY 900g Inwall System

Wow, thanks Guys!


Typhon,
yes, lets hope for everyone one`s safety... that the reactor keeps up ;).

Tigger,
Yes the base was mdf coated with the same epoxies as the skimmer...just tinted black.
The end result for the windows ,(not the first one) was 1/2 clear plexi.
Plexi was the best for this because i was able to build the window to actually hug the channel on the body of the skimmer and strengthen it all up at its weakest points.
This gave me over 2" total of silicone seam width, and gave this windowed area the strength it needed.

I would change it up abit on my next one....(DOH! did i just say that?)

Matt, Sorry, i just grasped your question properly now i think.
Yes, the base was built 3/4" taller than the lowest fittings, so none was being pushed on.
Actually, i have pretty short, and most unflexible arms...lol.
But all i did was tack it together, than place it back in the mold, cut out the windows so i could do the final interior lay up`s of fiberglass.

Like so,

Chris, well i guess im a machine that bleeds a hella lot when doing DIY. ;)

The body wall thickness were an unknown for me when building...i would guess at an average of 4 ml. with the base and edges 5-6.
The body flange was actually poured with fiberglass shavings to a 1/2", to match an upper pvc flange of the same thickness.
I carefully watched for any flex during wet testing, the poor spot was the window area where a lighter fiberglass was needed to conform to the shapes.
This is why the windows needed the extra work.

But i would build the next thicker, to be a bit more forgiving of any damage.(doh..i said it again! )

All in all i used 2.8 gallons of epoxies.

I feel like i'm watching a Mcgavier episode!

Do you keep how handy you are under wraps?

Because if my wife knew I could build things the way you do, trust me when I say that I would never have time to work on my tanks-

Absolutely stunning tank! I would love to see some video!
 
your diy tank, aquascaping (!), sump, fish room, skimmer has been a very big inspiration for me. a very large thanks for taking the time to share with everyone! your ideas will be infulental in my personal tanks, and equipment rooms.
 
I bow down to you! That s hands down thebest DIY Skimmer I have ever seen! Two big thumbs up..:thumbsup: :thumbsup:
 
A small update,

The skimmer is performing admirably, and now consistantly pulls atleast 3 liters a day of Nog.
I do have to adress the heat however, mostly due to the air pump...aswell the GG wheel makes the darts run fairly hot.

I did have time throw together a self cleaning squeege type head.

I just have to cotter pin the wheel that rotates the head, as it slowly slides down the shaft, and comes of the plate that spins the head itself.
But heres a small vid i did with the camera, so please excuse the quality here.



Also if anyone is interested, i have a little more detailed build thread on a local board, it has many pic`s of the whole project that werent shown here.
It provides a little more detail of individual equipment builds, but as yet still needs more to get up to date....

I had played with some more Aquascaping, and had a chance to actually take a photo of the glassed side of the tank ! :rolleyes:

Pretty soon, i might even be satisfied enouph to show a FTS..lol.

Marc,
You could go one step further and add a third wiper to the arm and scrub the inside of the cup too:)
 
Thanks guys,

Chris,

I could too !, i also think you might have contracted the same disease i have for simply thinking such a thought. :P

BTW, outstanding job on those skimmers in the other thread...i wish i could get seams to look like that.
Maybe you could teach me that, and how the hell you pull the methylene chloride applicator out of the project without squirting a streak of it all up the side on its way out !...

Marc.

Thanks Marc! Didnt realize you were talking about my stuff:)

Oh, yes I have that disease. My wife gets PO'd because I wont hire anyone to do anything. "I can do that!"

It took a lot of practice and getting stubborn old acrylic guys to reveal their secrets. Then James (Acrylics) comes along and dumps his brain out for everyone here- A true gentleman in my book.

The seams- the stuff needs to be baby butt smooth and NO gaps. I will even scrape any router marks out with a new razor blade held at 90deg to the edge. Then use shims if you have to to make an even gap along the whole edge. If your tools are good, you usually dont have to shim.

The Weld On bottle-
(I never use syringes for solvent, just the needle tipped bottle)
Only fill it halfway. Squeeze the air out and keep squeeze pressure on the bottle just enough so that you can invert it without losing a drop. The vacuum formed inside the bottle will hold it in there. With bigger needles, you will have to allow some air in slowly to keep the solvent from leaking out.

When you get ready to glue, squeeze the bottle, invert, then slowly ease up on your squeeze so the glue wont flow out. Now lightly squeeze the glue out til you come to the end of the joint, then let up so the bottle will not squirt out. I usually immediately squirt some glue out of the needle onto the ground or in the trash to be sure no melted acrylic clogs the needle.

Long winded, but hope you guys see what I mean:D

Looks like you of all people dont need a tutorial from me:cool:, but hopefully it will help somebody.
HTH

I am a newbie and it all helps me. I am really wanting to play with acrylic. Soon it is on my list. Thanks for all the info guys. I as all of you share Carma..

Thanks for sharing
 
NP Eric:)
Be sure and sift through the Chapter threads about acrylic-
"Acrylic fabrication questions", "DIY Tank step by step", "Pins method of acrylic fabrication"

Those have a ton of info. It'd be nice to take all of it and put it in one Tutorial thread that doesnt get clogged. Not that peoples questions are bad, its just they get asked over and over.

Ooops, sorry for the hijack Marc!
