one of our fellow jocks asked me to help him thru the process of makeing a shelf similar to one i had posted , i ageed and he called me . well over the phone wasnt going that well so i told him id try to do a blog . this will be the first time so ill give it my best shot !
the one im going to do has the sides flared back to the wall at 30 degrees instead of returned back on a 45. like a mantle top would be if you prefer its the same process just cut 45 s instead of the 30s
first ill make the bottom piece . i made mine about 2 in. wide and about 24 in. long i cut a 30 deg. angle on both ends . and i routed a small profile on the front and sides
next ill cut the crown moulding . when cutting this on a mitre saw you would lay it on the saw upside down
and make sure the back side is flat against the fence ( see arrow )
you can check to see that you had it bedded right by laying the piece on its face and with your square check the cut at the bottom edge it should be sq. .
cut the front piece at the proper length with an outside corner cut on 30 deg. on both ends . and then the side pieces get cut the same with outside corner cuts at both ends as well and both 30 deg.
now ill apply the crown mldg. to the bottom piece with a little glue and a few brads . i usually put the front piece on first
then i apply the two sides . youll want these to be exactly the proper length any discrepancy will show up when you mount it to the wall . again i use glue on the crown joint and the to the bottom and a couple brads
next i make the top . i allow a 1/2 or so overhang on the front and two sides . and make sure the back is flush . notice the two holes i drilled and counter sunk . these want to be 3/8 in from the back edge and 4 or 5 in. twords the center . i now router a small profile on the front and sides . personally i usually do the bottom edge where the top meets the crown . but thats what ever you like better , you can do the top instead or even both
then i attach the top with brads up thru the crown into the top
next i make a piece of deadwood for mounting to the wall from the back i measure the with of the cavity, and cut a pice of scrap that width and short enough to fit in the cavity
this piece will get mounted on your wall with screws and hopefilly catching a couple studs then the shelf slides over it and two screws in the holes that were drilled thru the top down into the deadwood . and thats about it hope it was understandable and not too ugly ! thanks
