[TherealplexiG]

Really?
Then its bang for them bucks..
I got this complementary though!
Waiting for some cool projects to use it..This kit so dang xaxy that i aint got the heart to use it. I have put it on the shelf for a while to get over it. :p

Magnet holders!!!!!!!!

Do you have a finished pic of those magnets?
What about air entrapment? are you gonna use any sorta epoxy inside?

Tackling that project this weekend. no, air inside won't really matter.

@cromag08
What magnets to use?
I really hate the math to figure that out, are you using those for frag racks?

 

[cromag27 Verified Sponsor]

Neodymium. they can be used for a lot of things, frag racks, acclimation boxes, float switches...

@cromag08
Yeah i know neos to be used, but specifically what type or size to be used for different glass/acrylic thicknesses?

 

[cromag27 Verified Sponsor]

A lot of expensive r&d. I just different magnets until I find the right ones for my project. you have to think about the strength raring of the magnet and the distance the magnets will be apart from each other.

Ordered about a 100 of 1 x 1/2 x 1/4 thick neos n52 or something. Do you think that's gonna work out for 1/2 thick glass/acrylic ???
Or do i have to stack them?

Eyo cromieboy those little things cost a fortune. But i ain't trippin this diy thang is ma drug!
I'm really exicited how this is gonna work out for me..

Maybe a small float switch bracket? you still need to encapsulate them in plastic so they're water proof.

Whoa. Interesting.

Yeah my plastics supplier grilled me today when I went to buy sg 4. luckily I also work out of a shop. lol.

Mix your own it works better long term in my experiance. I do not use TCE at all in my mix.

 

[Turbo's Aquatics Verified Sponsor]

Yeah, didn't even know what that was...I'll stick to my MC & AA :p but it sucks for the general hobbyist who wants to build something, what are they gonna do now?

Flexural strength σbB MPa
Polycarbonate - 90
Acrylic - 115

Takes more strength to flex acrylic? so it's more rigid than polycarbonate?

Yes, acrylic is more rigid

Dang! So if I am reading this right there will be no "legal" way for a consumer to get and use "weld on 3 and 4?"

 

[cromag27 Verified Sponsor]

Only 3 and 4.

I'm pretty sure this is why you can't get it in the UK or most of the EU very easily either...

This is going to make it just that much more difficult for anyone to DIY a tank the right way, at a reasonable expense. Fortunately, Methylene Chloride is found in a lot of cleaning products (solvents) and so it's readily available through all kinds of sources. You just have to find one that is high purity for a reasonable volume, and in a good package, and it'll never go bad (like WO3 or WO4 can)

Then just get a really small amount of glacial AA and a mixing bottle, good to go. But, just one more thing.......
