Coped the design almost to the "T." I loved this design because I only have a small shed to work out of and this stand for my miter saw was much needed.
The major difference between the original and my design are the folding arms. I was working within a very small budget and couldn't afford the fancy folding arms so I was able to do a little creative thinking and decided to go with a removable piece of 1x3 that is wedged under the arms with a block installed on the "leaf" and the main table. I used the old pythagorean theorem to figure out how to make it a level 45 degrees. With a little playing around I have both arms completely level and the stand is perfect!! I am excited to get some other projects on the way now that I have somewhere other than the ground to work with my miter saw.
I didn't use any pocket holes, but am picking up a Kreg jig set from someone this upcoming week and am looking forward to putting that into some use on my next projects!
