alcove shelving

by **paulturner1974** » Thu May 15, 2008 12:02 pm

im thinking about putting a shelf up to put my fishtank on in one of my alcoves. the gap is about 1.2m how much weight could three 47mm x 75mm battons across this width take? (worked out the weight to around 450kg) any help would be much appreciated

the weight is all wrong it should be around 100kg (converted gallons not litres into kg DEEERR)

each batten will carry one third the weight, or 35kg give or take. shouldn't be a problem though they may bow over time, i'd be inclined to use 4x2 or 50x100 instead. but the shelf will still only be as strong as the fixings in the wall.

I would be wanting to support the shelf with a simple frame at either end that takes the load down to the floor and not directly into the wall as you will need substantial fixings to get it to stay in the wall otherwise.
