Mark 5mm in from the edge of a slot and using your drop saw cut straight down (0°).
Now adjust drop saw angle to 45° (right hand side) and lock into place. Line up the blade of your saw to the bottom right hand corner of the grate and secure grate before cutting.
Once angle has been cut, remove the top grate and replace with bottom tray. Cut again at a 45° angle and set aside.
Repeat steps 1 through 3 with new top grate and bottom tray flipped
Once all pieces are cut, line up together to see how the slots line up.
NOTE (Top tray only): You may need to trim a little more off one grate to achieve an even heart shape look. Once cut, to trim the grate
further you will need to flip the grate over to avoid blade catching. (This relates mainly to 100mm wide grate).
Cut grate to desired length.
Tip: Cut angles first before you cut the grate to the length you need.
