I came up with this idea for a power tool while watching a professional framer blaze through some cuts. He would rest the board across his foot so it was angled towards him and finish the cut with a circular saw. I use this method as well, but I am a remodel guy so while I do a little framing, I don't do it 24/7. I would need a speed square to make those cuts, this guy on the other hand had linear guide rails for arms. Scary fast, scary accurate.
This is a tool for the rest of us that don't have linear guide rails for arms,one that you can drop down anywhere on the jobsite and knock out those cuts with speed and accuracy. Check it out and if you like it, I would really appreciate it if you posted a response at the end of the article. hopefully if there is enough positive feedback a tool manufacture will pick it up.
