Guys, just an update. I've got all the skirt boards on and risers, 2 treads left to install on these stairs. I made templetes for all the winder stairs, and it is going great. We are using 3'' wide by 1'' thick tongue and groove pine for the treads. I know about the longevity of pine, but believe me there was no talking the homeowner out of it you know what I mean. I finally said, you want pine, lets install pine. I will post pics we had to get some flex trim to cap the skirtboards. I am having one issue. When I scribe in the winder treads my old Milwaukee jigsaw blade is allowing my blade to flex and causing a front bevel on the tread material. I am having to go back and back bevel on the miter saw. I am looking at possible upgrading jigsaws, has anyone had any experience with this. I am thinking about getting the Bosch JS5, but i don't know if that is the issue.
