How come you stopped making videos brother? I see this was your last and it’s 7 months ago? are you loving the grapple? You made the install of the 3rd function for the grapple look easy. You should keep making videos, you’re good at things and filming it too.
Sch 40 PVC is not a good idea. Fittings and Pipe cost a little more but the pressure rating and Burst strength of Sch 80 is MUCH Higher and safer. Sch 40 = 480 PSI Water Pressure max Sch 80 - 690 PSI Water Pressure Max. Air Pressure should never exceed 1/4 of Water Pressure Max rating as "Working Pressure" ie; sch 40 = 120# Max (ultimate max too, any more is grenade territory) sch 80 = 173# max ( comfortable margin of common 125# line pressure, 150# is still close ) All ratings @ 73* F - De-rated 12% per 10* rise. ex; 62% of rating @ 100*F, 22% of rating @ 140* That means only 43# working/line pressure at 140* PVC is not good for higher pressure. CPVC has Similar ratings, only about 10% higher
