!!!FINAL DESIGN !!!
This is a simple 8 inch shelf bracket that i designed for a 10-12 inch shelf. This shelf bracket is crazy strong I'm even surprised at how strong this is myself. It's even able to hold about 70 lbs by itself and 40 lbs at the very tip of the shelf bracket itself!!! And yes it's holding 2 cinder blocks and 2 fire bricks and it still could handle more!
After a stress weight test, I've found out that the current design can hold over 120-130+ lbs, The brackets failed at 170+ lbs.
Changes:
Moved the screw holds to allow for stronger hold to the wall and shelf.
Complete redesign of the structural supports and no holes going through any structure.
Supports are thinner than the rest of the bracket allowing for a screwdriver/drill to pass by while installing bracket.
Lowered one of the wall mounting screw holes to allow for easier install and to keep screws from potentially colliding.
removed a top shelf holddown screw hole for added strength
**removed a wall mount screw for added strength
** added a small taper at the top corner for added strength
Please leave any feedback you might have as I appreciate any suggestions for future designs.
