Building Shelves!!!
I agree. MUCH BETTER than anything you can buy. Yes, lt. Bob is correct, records are HEAVY and shelving will need adequate support, will rip screws right outta dry wall if you're not careful.
Best bet for adequate support. Go to Home Depot and pick up a 'stud finder'. Electronic is best, can get a good one for $21 bucks. Go to a corner of the wall you want to place your shelves on and glide stud finder in a 2 ft. section from left to right until it beeps. Mark the wall, then measure 16 in". from first stud to center of wall, check with stud finder and you should be dead on another stud. Continue finding stud location for the desired length of your shelving. With your studs found, you can then screw 'heavy duty' shelving brackets in, using a level and or 'snap line' to ensure even height. The 1x12" are perfect although you may have to do a bit of research to find the appropriate size brackets. With all said and done, you should have nice shelves, fastened securely and a lot of money left in your pocket!!!
Note: for additional support you can 'notch' 2x4's and strategically place them on front ends and center of your shelf wall. Tools needed: Hand Held Skill Saw, $30-$50 at Home Depot, patience and a tape measure.
Good Luck.
Sounds like a great collection!!!
