I need to replace sections of some rotted red pine, tongue and groove flooring boards in a Victorian house built in 1888. The flooring is bone dry and had been covered with subflooring many, many decades ago.
We are going to have the flooring sanded and refinished but have to fix this condition before we do. As I have to replace about 10 boards about 24 -30 inches long, I want to stagger the joints every other piece so it will be less noticeable compared with cutting it all over one joist.
How do I cut the existing boards so that the circular saw blade kerf does not cut the adjoining boards? The boards are random width, ranging from 2-3/8 to about 6".
Thank you for your consideration.
