How to Cut an Opening in Lap Siding Part 2 How to Cut an Opening in Lap Siding Part 2
In Part 1 of this series on how to create an opening in lap siding, you learned how to choose a location for the opening, measure and mark the opening with a chalk line and cut out the outline of the opening with a chisel and circular saw. You are almost finished and don't have a whole lot left to do. In Part 2, you will learn how to create curved cuts in the siding,o use a jigsaw to cut out the corners and remove the section of lap siding from the opening area.
Step 1 - Cutting Curved Lines in the Opening
If you need to cut a curved line in the opening of your lap siding, you can use a pencil to create a curved lines or draw one freehand. However, regardless of the method you use, you should use your tape measure to measure and mark the outer dimensions of the curved line or arch.
Once you have created the curved line drawing on the wall, you can use a jigsaw or reciprocating saw to carefully cut along the line in order to create the curve or arch. To do this, you'll need to create a pilot hole so that you can insert the blade of the reciprocating or jigsaw. Align a drill and drill bit just beneath the line you created with your pencil or marker. Then, drill one or two holes so that you can insert the blade of the jigsaw. Once you have created your pilot hole, simply cut along the curved line to create the curve or arch.
(Tip - If you are cutting metal or vinyl siding, you can use the same process to cut curved lines in lap siding. Just be sure to use the appropriate blade for your jigsaw or reciprocating saw.)
Step 2 - Cutting Out the Corners of the Opening
In part one of this series, you were advised not to use a circular saw to cut the corners of the lap siding. This is because it is extremely difficult to create precise corner cuts with a circular saw. For this type of cut, a jigsaw or reciprocating saw is a much better choice. Therefore, you could simply cut from the end of the line you created with a circular saw all the way to the corner of the opening.
(Tip - Try to set the depth of the blade so that you don't cut too much into studs that may be behind the lap siding.)
Step 3 - Removing the Piece of Lap Siding from the Opening
Once you have finished cutting out the piece of lap siding, used the pry bar to gently remove the piece from the opening. If there are nails that are holding the wooden lap siding to studs, use a claw hammer or nail puller to remove them.
Step 4 - Cut through the Sheathing
Once you remove the lap siding, you can use your circular saw, with a wood cutting blade, to cut to the wood sheathing beneath the lap siding. You can also use the circular saw to cut through nonstructural wooden studs as well.
