Retired,
A 3/8 inch diameter magnet with a 1/8 inch hole in it and 1/4 inch thick has less than 5 pounds of pull (with a thin gasket). The magnet I am using is 1/2 inch in diameter, with and 1/8 inch hole and is 1/2 inch thick. It has a 16 pound pull. I think that's the difference between what you are doing and what I have done here.
P.S. I'm working on my second million.....my first one didn't work out worth a $#@*.....
Oh man we need to ALL work on this in the coming Winter (you know right after hunting season when we're all cabin feverish and stir crazy and posting to/starting endless loop threads*) and decide exactly (
and uniformly like any good herd of cats)
the following details:
magnet-shape, density, diameter
gasket- material, thickness, and durometer reading.
per flash hole construction--yes there's going to be more pull from any serious magnet where the hole is a simple thru-bore than where coning has removed bbl steel by insert or actual internal relief. Of course the internal relief type won't lose as much pull as the drilled and tapped insert. Also there's the carbon steel insert to consider. Smaller bbls are going to give less pull too, but smaller bores might generate less internal pressure. Hmmm.
What if we make an
electro magnet for the purpose? Then: voltage, voltage source, windings, core materials, polarization, etc.
So much to consider. I'll be ready for that in February or January.
*endless loop threads that come to mind:
-
patching (thickness, material, sources, lubrication, shape)
-
cleaning (solvent
, material, after oiling)
-
softening fouling by breath-
caps vs. rocks-
P-word is the Devil -
where to get BP-
how they did it BITD. again
