A finish guy in Sacramento said my miters would never close because I was rushing the cut, not the glue up
I was trimming out a house in Sacramento last month and complained to the finish guy about my miters opening up on some prefinished maple. He watched me for two minutes and said my problem was I was cutting too fast, not clamping too slow. I slowed my chop saw down to maybe half speed and started letting the blade stop in the cut instead of pulling it out hot, and honestly the joints closed up tight with just glue and tape. Never thought about how much heat and tear out a fast cut puts on the end grain. Anyone else have a saw trick that fixed something you blamed on something else?

Wait, he let the blade stop in the cut? That blew my mind a little. I always pull the saw out while it's still spinning because I'm trying to be fast, and now I'm sitting here thinking about all the burn marks and fuzzy end grain I've been blaming on my glue up this whole time. The heat thing makes so much sense too, like the wood is basically getting cooked right at the cut line. I bet that maple was tearing out and closing back up just enough to fool you until the glue dried. Gonna try the slow pull thing tomorrow for sure.
