Bracing My Tank

[chr15_8]

lol

thanks momo, wouldv bit your hand off if you were closer lol

also, cheers jay, good advice.

Do you think I should think about perspex or just search harder for glass?

as said before perspex wont stick well using silicon. when you glue perspex the 'glue' you use melts the 2 pieces together.

when bracing the tank you want it to be as strong as possible. £15 for abit of glass is excessive though imo.

the glue i have used b4 to do my pipe work is the same (solvent glue ) like you said it melts the plestic together making it as hard as the plastic itself.

The glass itself is very strong in the way it will be used its not got up or downwards pressure on it its got a pulling pressure on it or outward force which even normal A4 paper is extremly stong if you try and pull it apart

if this makes sense lol not too good at explaining things lol

The joint isn't as strong as pur plastic as the carbon chains aren't fully fused it will be more brittle at the point of compact. You don't have to use silicone as the glue you can use others such as epoxy resins then coat in pond sealant or aquarium silcone

I upset Tesco's the other day MJ, I told their chemist that their acetone 40ml for a £1. was a con and I could get it on ebay for about £9 a litre or so, he wasn't amused and tried to tell me his was purer so I got the 500ml bottle out of my coat pocket and said"oh really, this says 99.9%, what on your bottle then" he got the hump.

lol no im not . not acetone 100% thinners lol no not around with me in my shed mate

Thats why I wondered why they carried acetone with them. It will get you high but is especially effective at cleaning glass as it doesn't leave a residue

i do abit of car body repair and spraying thats why i have 100% thinners

My post was directed at momo hence why the statement in question was in bold .

 

[mixmaster jay]

Sorry

No I dont normally carry acetone with me, I was on my way to tesco's with the wife when i caught the posty who had an order from a certain company I get it from. I never leave things in the car if I can help it and so took it in with me is all.

 

[saltynay]

Those teenage vandals now a days do anything for 500mls of acetone

 

[momo33]

S*D the vandals, I would be horrified if they stole my tank kit, they could keep the car though.

the stuff you use for pipe work is different. i tried using it as im planning on building a perspex sump and i easily broke the joint. The proper perspex stuff needs to be applied by a small syringe/needle i believe.

i know perspex is strong i wernt saying it wasn't. all i was saying is that using silicone isn't the best way to join it and it would be hard to get a descent joint between the two different materials.

its just applied different for acrylic (perspex) its in a mixer system that mixes the 2 chemichals together solvent glue and a hardener and it causes a chemical reaction between the two.or you buy thinner solvent glue and use a syringe. the stuff ive got on my solvent weld pipes is the same but a all in one mixture with a shorter shelf life

there is many different aplicators to use the main one for tank building is a syringe or simular to, with a thinner more concentated version
