A place to discuss aquaponics

I just did mine with an angle grinder and a 1mm cutting disc for stainless steel, they cost 0.99€ thats just over $1 each. Nice clean cut too

May be this is the tool we are looking for

Backyard Aquaponics has some great instructional videos on youtube which show what they would use and how they would do it:

Do not use the tungsten hole saws if you are going to use uniseals. They drill over size so be careful

way late here, but this.
i dont know why anyone would say "dont use this blade or that blade"..... its plastic, you could use a hot butter knife.....

I also bought one of those nice metal discs, have had it on the grinder for over 2 years now, it gets used for everything, literally everything.... metal, concrete, plastic, anything else there is that needs to be cut..... it hasnt been removed since it was put on and have saved many, many dollars on those silly wearable discs....

Also once the guide hole is drilled, run the holesaw backwards on plastic if you want any sort of clean finish - they grab really easily otherwise.

This was helpful was thinking I might have to buy a jigsaw but will give my grinder a whirl.. Once I find a suitable IBC!

Jigsaws are cheap and so useful, and the ducks guts for this job

hmm pronbably handy.. but it means im a grownup if I have my own array of powertools. I've gone this long with handtools, welder and a grinder.

ow no one mentioned det cord???
You wrap it around at the height you want to cut it at, connect it to the plunger and in a puff of smoke you have a nice clean cut ibc cage and all .
Seriousness aside now angle grinder1 mm cutting disc for both cage and liner.
Although sounds like the circular saw is an easier way, cheaper than det cord as well.

reciprocating saw or jigsaw... both work.. reciprocating if you are going to buy only one and need to cut the cage too.

I have been using a battery powered angle grinder with great results, deburring tool to clean up the edge afterwards.

I just cut the top out of mine and I used a NiCad Ryobi jigsaw with a 6tpi blade. More like ripped through it instead of sliced but very easy to control on slow speed. The blade on a pair of scissors cleaned the edges up quickly. Layout cut and clean took maybe 20 minutes.

6tpi is pretty aggressive, sounds like a soft timber blade?

im a big fan of my jigsaw, but i would try a blade a little less aggressive personally.

I use a cutout tool. Its like a fine router. Easy to handle and did a neat job. But the jigsaw with a suitable blade is probably what mist people have at home.
