Need Electromagnet help for table saw jig hold down. Answered
I'm making a table saw feed kit, that also required that I make a fence for it. I decided to make a fence out of wood, that I jointed square. So you folks can get an Idea, I have pictures, at least for the feed kit. And yes it does feed wood across the top of the table, like it should. I just haven't tested it with the blade running yet, but I'm sure it will work fine. It's likely I will write a comprehensive guide on how I did in the future.
The issue I have is with the fence. When I clamp it on the end of the table saw it lifts up in the middle where I mounted the power feed. It's essential it remains flat to the table.
Today, I made an electromagnet with a 5/8 bolt and 2 washers using 26 gauge winding wire, It GOT WAY TO HOT!
I have seen door electromagnets, which leads to my question. If I use this type of magnet, will it still get extremely hot? I'm referring to the ones that have about 100lbs of hold down force, and are about 25 dollars.
I'm aware that twist lock magnets are available, but they are way more expensive, plus the same power supply that drives the steppors can power the magnet.
If someone can get me in the know I'd appreciate it.
