I will sand the front frame with a speed file which takes a long thin sheet of sand paper. Good for getting surfaces nice and even. Sometimes Joe the old ways are the best ways. Compare how furniture was made 50 yrs ago to the stuff you buy today........My house is furnished with antiques, most well over a hundred years old, some made from american oak and its all still going strong. Not that I have the talent for work of that standard but I do respect what a decent craftsmen can accomplish.
I'm a stock trader Joe so I work from home and have ample time to indulge in what happens to interest me. My GF complains I have way to many interests and now she is worried that the ground floor of our house will be covered in fish tanks
As for our weather, you could easily compare it to Florida, same yearly temperatures only diffence we are now in mid summer.......
I also live within about half and hours boat ride of the great barrier reef, the biggest coral reef in the world. Plenty of nice fish out there
Back to the tank, I now have 95% of the ply cut just need to drill a whole bunch of pilot holes for the screws. I have this idea to use some inch by inch to strengthen the the tank along the ply joins internally. Also thinking on a product called pond tite which I would say is similar to your previously mentioned sanitred. It comes in a nice blue colour. If I use it on the tank I still won't paint the front frame with it as I definitely want the silicone to bond to the resine/glass. I have a few more ideas to but best I post some pix of what I'm going to do cause my way of explaining is probably not clear enough
Some will probably think I'm not building this tank strong enough but after looking at what those that have went before me have done I think what I have in mind will work fine. It won't be massive overkill, just solid and reliable ...........I hope
Yeah Chris I ll keep putting up pix long as you guys are interested.
