how can fix these holes

[sammfk]

can any one give me some advise
i have several holes drilled on the back of this acrylic tank.

tank thickness is 1 inch all the way round, these holes are 10mm thick and have cracks between each hole joining them..

do i need to piece in a hole new piece of 1 inch acrylic or is there anougher way..

sorry for the poor photos

thanks

Buy a piece of acrylic (best if you can find a local acrylic or plastic supplier rather than the this stuff they sell at local hardware stores) that is just the right size to fit inside the tank lengthwise and to go from the bottom up high enough to make the row of holes be in the middle of the new piece. Get the right kind of acrylic glue and glue it in place inside the tank.

The glue will actually melt the surfaces of the acrylic so the merge rather than stick to each other. And if I were doing it I make the new repair piece black or blue so you can't see through to the row of holes. If cost isn't an issue, get the new piece so it just fits inside the tank and goes all the way left to right and top to bottom and it will look better.

Good luck.

thanks for the advise really helpful..

what thickness of acrylic would you advise to cover the back

I didn't realize how big that tank was until I saw the kid in there .

Was someone using it as a work bench or something?

I would go close as possible on thickness for the new piece and run a full piece inside like Ron has recommended. Solid colored.

I would also add a couple vertical strips on the back of it. You pretty much have a piano hinge type scenario going on with it now.

Out of curiosity what is the purpose of the holes? My interest is peaked.

And don't tell me they're air holes for your daughter!

hi thanks for the response

the wholes were drilled by a tank manufacture i bought this off them thought i could do somethung with it...
so i need to get at least 15mm sheet solid colour the inside ?

If I had that tank and added a full piece inside the back, I would have no issues using it. The only part that concerns me is they turned the one panel into 2 with the holes running across it. I wouldn't think the exact thickness is needed, but wouldn't go thin either.

They original corner structure is still solid, just trying to enforce the load bearing area they compromised.

Half sheet or strip on the inside will not off load the stress load of the full back panel.

You could also do the wood fiberglass that others do on here. Seen some amazing builds on huge tanks with people doing it that way. Or maybe just fiber glass.

Might want to post up in the diy section, some real rocket scientists in that area.

As small as those holes are.. if you use a thinker weld like 16 you can likly fill those in wo needing to cover them. Acrylic glue has some melted acrylic in it already. I’d try that first as if done right you could make them invisible..

I’d use silicon to glue a small piece of glass to the outside and lay tank down.. then use a thicker weldon16 and just try to fill only the holes.. might even need to go thicker then 16. The glass and silicon will keep the glue in the hole and from just falling out allowing it to puddle and sit. Once dry remove the glass and silicon and water test it..

I know for sure you can do this.. the issue is what thickness Weldon do you need and depending on the size of the hole you may need to add a little bit of shavings with the glue to properly fill.. but these in the picture like super small like 1/8” so a thick Weldon should be good enough to fill.

Another option you can try.. get a cheap piece of 1/8” from HD use a saw and sit it into a bunch of pieces to get a lot of small shavings.. place in a container and pour in acetone little by litttle till you get a superglue gel type consistency.. all acrylic glue is is acetone and acrylic melted in.. you can make your own and control the consistency this way to get thick enough to stick and thin enough to till the hole at same time..

Or you could use Weldon 4 and shavings .. put a few shavings in the hole on inside of the tank.. filling it.. make sure it’s flush with panel. Stick thin needle of glue from outside in and seal.. this now gives you a start.. from outside insert more shavings then glue.. the more shavings then glue.. over and over till flush inside and out..

All different ideas.. delending in the size of the hole you’ll have to play with it to get the right fill. The bigger the hold the more fill you will need for binding the glue and keeping strenth up. Of hole is too big and glue to thin you’ll have a weak repair that could fail..

The idea is to fill with as much acrylic as possible and then use glue to bind it back.. thicker slower drying like 16 or even 32 will be better then the thin water type 4 as it has more acrylic in it which is why it’s thicker.. (better structurally for filling gaps) Weldon 4 as common in acrylic building is for tight seams..

If the tank is glass I would recommend having the entire front section replaced.

Whats the measurements on this beast?

 

[Darth.Daddy12]

Did some more research into what size gaps people are filling with what thickness Weldon.. somewhere around Weldon 16 or Weldon 40 should be able to fill those in no problem if they are 1/8” to 3/16” size..
All you need is a way to keep the glue from falling out one side or the other and something that it will not stick to.. I think even painters tape will work. Then fill from other side and let it dry.. the thicker the fill the longer the dry so even weldon16 might need say 2-3 days to cure be the normal few minutes. If it doesn’t work you can always get a full sheet and backface the entire panel as mentioned.. it won’t need to be as thick cause you’re structure is intact you just need to block those holes.

Issue with it being the front of tank it’s going to look horrible if a patch is out across the bottom, and if you put a full pain over top the clarity will not be the best. I would recommend going to a local acrylic place to have them replace the panel.

If done right it will look the same as if they were never there..

Adding another pane still leaves visible holes so I don’t see the difference here lol. A little buffing might be needed when done but this is no different then not seeing the seems on the ends. I also don’t think the OP was as concerned about appearance as he was function as he did buy a tank full of holes in the front viewing pain lol. Filling the holes is the single best , cheapest and visually appealing option.. it might be slightly cloudy when done but won’t be an eye sore unless you’re looking for it and know it’s there. There’s a lot of things that you can’t see when you’re not specifically looking for them. No one who comes over is going to be looking for 100 holes patched in someone’s tank..

Tank is arcylic

Holes are in the back, not the front

It has 46-47 3/8th holes in it.

Holes are connected by cracks.

Initial post was 1 question, a whopping 3 sentences of info that were separated, a apology and a thank you.
