Magnets to pick up grills

Phil,There are different types of stainless steel. Some are more stainless than others. Some of them are martensitic which means they can be solution heat treated and then quenched where the Austenite transforms almost instantaneously into untempered martensite. A tempering operation is then performed to achieve the desired hardness of the material. Stainless like AISI 410 series is this type. This is magnetic and if the MAgma grills are made from this then your magnet idea will work. Unfortunately these will corrode and rust very quickly unless plated or otherwise treated.Most likely the grills are a 300 series stainless like 316 or 304 which is non magnetic and so your magnet idea will not work and you will have to scuba dive to find your missing grill. Happy diving Phil.Dave

Lost anchors

About 10 or so years back the I-90 floating bridge sank. A buddy of mine worked for a company that did some work on the repair and was on a boat that raised one of the many stabilizing cables that anchored the birdge to the bottom. Their one cable came up with something like 100 anchors attached to it! In fact, he took home a rather nice Fortress, as I recall.

WOW!

I was gonna put my 2 cents worth in, but this has gooten WAY TOO HEAVY for me!

2 cents worth

Sorry Jim, pennies are non magnetic since the old ones are copper and the new ones are something else like nickel or aluminum plated with copper. So your 2 cents will not be able to be retrieved by Phil's 150 pound magnet.Now in the interest of safety OSHA does not allow workers to lift 150 pounds of anything, so I urge all my fellow website readers to use the utmost caution and get help when trying to manhandle this device.Best regards,dave

New pennies are 90% zinc and non-magnetic

John Withrow....

...have we answered your oiriginal question?

 

[Dave]

Pennies are Zinc!!!

This is a tremendous revelation.When I buy a zinc for my boat it costs about 12 bucks. If I get 12 bucks worth of pennies i will have a lot more zinc than that!!! It sounds like we can all use pennies for our galvanic corrosion protection and save a lot of money in the process.Thank youdave

How can we stick the pennies to the prop shaft?

Velcro? Scotch tape? Hot glue? ...(To paraphrase Monty Python: "This thread has become very silly!" Spring fever?)

 

[Dave]

Strategy

What we need is a strategy. No need to attach pennies to the shaft. Here is a possible alternative. Put a bunch of pennies in a brass c-clamp and clamp them. Attach a wire to the c-clamp and the other end to the shaft. Now take an aluminum can and attach a wire to the ground wire of your system and the other end to the can. Insert (suspend) the c-clamp in a brine solution in the can but don't let it touch the sides. Over time the zinc from the pennies will plate onto the can where it will be retained and then you can re-melt it and have a lifetime supply of zinc for no additional cost. Of course all process are non-reversable due to entropy so you will lose a little over time but this will be much cheaper than purchasing zincs every year.dave
