I realize that this is probably a very basic question but I'm not hugely experienced with DIY so I'd appreciate some help with it. I want to put up a 1M book shelf using 2 x 25cm mitred brackets with 3 x 5mm screw holes down each length. The wall is brick with plaster on top and 15cm thick. The bracket designs go from a point at the ends to a wider point where the two lengths meet so the 3 holes are 1cm, 1.5cm and 2cm away from where it will meet the wall. I want to use this for fairly heavy books so I am looking at something like 60Kg maximum. I was looking for advice about exactly which screws and wall plugs I need to buy to ensure it is a secure fit for a fairly heavy load? Thanks

Hello I have sold a few LED floor lamps that look like this: [attach]98223[/attach] There are three layers, with the middle layer being a kind of skeleton with the LED lights mounted there. The outer layers are solid lumber. I'd like to expose no fasteners of any kind. Up to now I've been joining the skeleton to one layer with screws from the inside, and gluing the third layer to the skeleton. But ideally I'd like a way to be able to undo everything in case repairs are required, or at some future time when the LED's expire and I could replace them. I suppose I could screw and countersink the outside of the third layer and plug, but that's not ideal. Can anyone suggest some kind of fasteners that would be used between the layers and could be undone when needed? I hope I have made this clear. Thanks for reading. Paul
