Could the pinhole improve the ball bearing valve behavior ?

Re: Entropy

I presume there are shapes inside that trap air. A design mistake or a convenience about something else. Centrifugal pumps I am well familiar with don't have such vent. They do need pipes, at the outlet side, without any air trapping shapes. That is a must for easy priming. At cold start there is al...

Re: Entropy

I used a 555 on a weird project. That was for a crack pot guy who was curing all sorts of diseases with pulsed magnetic fields. He was making coils of all sizes, for arms, legs heads, bellies even XXL for obese people. I visited his place, saw his winding machine and the equipment to pulse the coils...

Re: Entropy

it starts from pretty low, only a couple, inches from the impeller level. Looks like I have a like good spare sump pump. It is a low tech design using a 555 and a few discrete components. JR I am curious about sum pumps priming. Impeller....inches from under or above water level ? What is the 555 t...

Re: Gentle persuasion over time

I understand the relief when the last one is down.
I lived this at a place of mine and the place of a son.
One uses to keep the most difficult tree, last.
As you had, nobody hurt ( and a chain saw blade bent ).

Re: Gentle persuasion over time

The troubles with steering lines: Nylon lines are too stretchy to pull hard when the tree starts to fall following gravity. Steel lines are stiffer, but damn dangerous, if it breaks, the backlash is deadly. I know a way they use in Australia. They use a steering line that goes at a pulley at some lo...

Re: Gentle persuasion over time

Tree is down.
Great. Job done.
I understand the steering line had no effect.
I doubt more tension would have make it effective, this rarely works. A steering line can make things more dangerous.

Re: Entropy

I have a power meter and see a difference between pulling air and pulling water This could be a nice way to detect water low enough to turn the pump off. Nice because this is free from float switch issues and keeps pumping at the lowest possible water level. The float assembly actually has two floa...

Re: Entropy

The ground water level down in the crawl space was finally high enough to turn on the sump pump... I may revisit this weekend to reconsider the float threshold level a little lower. [/update] JR The lower the better. But.... 1 When set too low, the pump might never stop because of loosing priming w...

Re: Entropy

I purchased a stainless steel strainer to use as a basket to sit it in and keep major debris from clogging it up. A nice hillbilly stainless steel strainer is a washing machine drum. I have started dismantling a washing machine, a work for rainy days. The starting motor AC capacitor is another nice...
