ryanjury Posted April 16, 2007 Report Share Posted April 16, 2007 When I moved from Auckland to Bulls ages and ages ago the movers chipped my tank and I assumed it was too badly chipped to fill.. Have had a few people around since then and they've all told me it should be sweet and to fill it which I was going to do today im still a bit worried about it all though so ive taken some pics which should show the extent of the damage and ill ask around here.. There are 2 chips on the front RH corner (well 3 but ones really tiny so pictured the worst 2) And 2 on the bottom RHS. Quote Link to comment Share on other sites More sharing options...
Bluetom Posted April 16, 2007 Report Share Posted April 16, 2007 I'd say it would be fine. how big is the tank though? could you fill it outside first? I doubt it would effect it really, my sump tank has quite a few chips in it. Quote Link to comment Share on other sites More sharing options...
ryanjury Posted April 16, 2007 Author Report Share Posted April 16, 2007 Its 5 x 2 x 2 ft so pretty big holds around 540litres.. A bit more difficult for me to take it ouside and find somewhere suitable to test fill it.. Also a potentail for a nice mess in the house if it were to let go..

Bluetom Posted April 16, 2007 Report Share Posted April 16, 2007 are the first two photos of the same chip? I can't really tell what size the first one is if they're not. Quote Link to comment Share on other sites More sharing options...
Faran Posted April 16, 2007 Report Share Posted April 16, 2007 Get an oilstone and wear down any sharp edges. This will strengthen the affected areas. Then, get some silicone and fill in the gaps. The silicone will be purely cosmetic, but blunting the edges makes glass much stronger. Quote Link to comment Share on other sites More sharing options...
Bluetom Posted April 17, 2007 Report Share Posted April 17, 2007 the sharp edges shouldn't matter too much should they? Considering the chip is alreay on the edge? I would think it would disperse stress concentrations from the edge rather than create more. Not sure if resin sticks to float glass but may give a more transparent look than silicone. (it should stick considering fibre glass) Quote Link to comment Share on other sites More sharing options...
ryanjury Posted April 17, 2007 Author Report Share Posted April 17, 2007 I dont really care about how it looks it wont look that bad, the 2 chips pictured are different ones on the front edge but the same depth so the one that shows the depth is the same for both.. Should I even do anything to them or just leave them alone and fill it? Quote Link to comment Share on other sites More sharing options...
Bluetom Posted April 17, 2007 Report Share Posted April 17, 2007 My vote is leave them alone and fill it. as it is a chip rather than a crack it is unlikely to create stress concentrations and propagate causing a large crack. And the thickness loss is pretty insignificant so as long as your tank hasn't been designed with no safety factor (highly unlikely) the strength shouldn't be effected really. I do however take no responsablity if somethings happens. but I'm sure it won't Quote Link to comment Share on other sites More sharing options...
Faran Posted April 17, 2007 Report Share Posted April 17, 2007 Lemme put it this way. You have a rust spot on your car. It's not really that bad and it's in a place you don't see everyday. Do you just leave it or do a little maintenance to clean it up and keep it from spreading? A small chip may not propogate, but the chips I see here are caused by sliding and are actually a few chips on top of each other. Seriously, it'll take just a second to round off any corners and dull the sharp edges. Just remember to move the stone only towards the edge of the glass and you'll be sweet.

quack Posted April 17, 2007 Report Share Posted April 17, 2007 yeah i think it would be sweet. havnt heard of the method that B&K is talking about(dosnt mean its wrong tho) but at the end of the day as he said its only going to take 2min to do. oh and yeah it will be a weak spot, and i would fill out side first.

ryanjury Posted April 17, 2007 Author Report Share Posted April 17, 2007 I think you looked at them when you were out blue and thoguht they should be fine but yeah might try the sand stone.. Quote Link to comment Share on other sites More sharing options...
