« Part 4: Initial Glue Up Part 5 of Weather Station series Part 6: Finished & Critique »

So here’s a little advice. When you are working with matching sets of magnets, great care should be taken to make sure to set them in place so that the poles do not… Oooooops! Dag-nab-it! #$%^$#&*! Yup, you guessed it. How embarassing is that? I glued the magnets in backwards so they repelled each other. What to do? What to do? How am I going to fix this mess? Should I throw it away and, gulp, make a new part? Is there a way to reverse polarity? Turns out there is, sort of. Here’s the solution I came up with. How would you have solved this?

First the problem. The top is designed to pivot to allow access to the hole that receives the Galileo Thermometer. It is supposed to be aligned and held in place by two sets of magnets. The magnets are supposed to attract each other, but what happens if they repel each other? A funny thing happened when I went to close the top.

So here’s my solution. I happened to have a plug cutter that was just big enough to circle the magnet.

I also happened to have some 1” diameter dowel stock so after popping out the plug and magnets with a screw driver I enlarged the hole to 1” using a Forstner bit.

Then I sliced a couple of disks off the end of the dowel, applied some glue and tapped them in to place. Then sanded them flush.

I realigned the drilling template using the pivot hole and re-drilled for the magents. Before making the same mistake twice, actually four times, I attached the magnets in the proper order and marked the glue side with an X before glueing them back in place with gap filling CA glue. Since the patch is on the bottom of the top it will not show unless it is removed and flipped over. But nobody will think to do that, right? :)

Nice save! Great tip on making the side of the magnet that you want to glue.

Here it is Monday morning and I’m still laughing about this. I had made a point of telling myself to make sure the magnets are aligned to attract each other and had given it some thought. There’s always a simple way to do something but first I had to think reverse and backwards and mess it up before it hit me. This was another great learning opportunity. Trial and success…
