Hell yeah wish you’d come to northern Arizona.
Thank you 🙏
I have been using and explaining these principles constantly. And if i have to hear " i have been doing this for 30 or 40 years and you arent gonna tell me" i swear im gonna throw a wrench. I routinely demonstarte sub 100 micron pulls that only decay to mid 100s. Inside 20 mins. And still i catch static feom all the guys in this industry. Biggest difficulty in this trade is the other "tradesman" and the exoectations set by employers
24:32 - Are you saying, here, that N2 in the system starts to mess with your head? Mind boggling the difference it makes!
Wait if you can only pull around 1/2 a cfm through a CRT tool (with standard hose sizes. Assuming 1/4”). Then how else are you removing the Schrader, pulling the Vacuum, and then doing anything else(like removing your vacuum hose) without losing your vacuum? Lol
A shrader removal tool.
@@jmank121 he says when you pull through a removal tool your only pulling 1/2 cfm max.. that’s my point though, im wondering if he meant to say if your pulling a vacuum through the schrader (as in “if you try to pull a vacuum with the schrader in your pulling 1/2 a cfm max vs without the schrader when you can pull 6-10 cfm with bigger hoses like the Navac “Big Boy”)
