Hi all & particularly Jasonb if his brains are around to be picked so to speak....
O.K. I have a customer that wants 2 x 3600mm shelves at almost ceiling height either side of her hallway. 25mm MDF, paperback deep and no brackets on show. One wall is brick, the other studwork. The shelves are just to take paperback books.
Have read several threads, particularly from Jasonb, outlining his method of bedding M12 threaded rod say 4" to 6" into a 14mm hole in the wall and say 2/3rd's into the shelf itself....eh voila, floating shelves. They look great & I've made floating shelves for alcove spaces, but not using threaded rod & not 3.6m long before.....
My questions are :
1/ for 25mm MDF would you recommend 8, 10 or 12mm steel rods ? I don't have a drill press but have a drill guide.....and errr....my super chippy skills to ensure the holes are drilled square !?
2/ what resin do you recommend to bond the rods in with.....? how long does it take to go off ?
3/ for ease of fitting them and machining them to size, I was thinking of 3 x 1200mm shelves (to make the 3600mm). Would 2 x rods per shelf suffice ? Also, am concerned about getting all 3 perfectly flush in a row, with no gaps. Any advice there (apart from making sure all holes are drilled spot on square / level and the rods are bedded in perfectly level ?) Was thinking of a simple 2x4 jig with 2 holes for the drilling, but if the hole in the wall is to be made 2mm bigger than the rod (presumably for the resin), would that not make it more difficult to get the rods perfectly level ? Would I be better going for a 2.4m & 1.2m length together ?
Would this be safe enough for the studwall too ?
Questions, questions.....
All methods and advice appreciated !
Cheers....Mike
