Good morning! Saw in final stages of assembly. Passed leak-down test last evening took over 1m32s to get from 80 kPa to 62 kPa and just sat there at 62 until I got tired of watching it. Will have new complete draft version of tutorial document posted for review in a couple of days.
WOOOOOHOOOOO!!!!

Has been a lot of work, perhaps it will help some folks out.
Next, we will be adding an addendum to the base document covering the experiment using a 365 SPecial piston in place of the 262XP piston. We will be doing this on another 261 so that we can publish a comparison video of the two saws. If I can figure out how to make and post a video!
