I have more than one scar as testimony to my carelessness with wire wheels. They have less than zero forgiveness....

Or a diamond wheel recently while cutting tile.. with no guard. while shutting off the grinder my finger slipped.. we all have stories.

It was an electric 4.5” grinder with a metal cutting wheel. It has a stay on switch. We watched the video from house cameras. You see him jump up and check his leg. Then he goes back to the grinder to turn it off and only then realizes blood is pouring out of his arm. He jumps up and runs into the house. Blood everywhere. No one else was home. He called me thinking he severed an artery. I called 911 as I drove home. I beat fire by two minutes. Kid had his arm bandaged and a tourniquet set out in case the pressure bandage didn’t work. Fire said they were busy and the ambulance was still a few minutes out. I transported him because he was stable and it was quicker.

Lately i've been very busy and i've been doing lots of repairs on machinery and vehicles but haven't had the time to share it. That said today with only few hours to spare i did bought me couple of wrench sets, i've been doing lot of work in the small garage over the inspection pit and all my tools are in the big garage, so i'll have to get more tools. The wrenches i bought are cheap chinese no name and the plastic holders they came with that i thought i'll use are horrible. The rest of the day i spent in the big garage organizing and checking rims, winter is coming and i know espacily the cars my brother is driving have square rims that need to be changed before the season, its astonishing how much a rim can be bent and the car won't have any effects if it has 65 series or higher tire sidewall. From those two stack only one really bent rim, that one is going for scrap.

I finally got the wood shop tools I need to build a table for a family member. (Re-sawing band saw blades, etc). It was time to try a small project to make sure it was all going to work. I had a small gardening chair I made in junior high school that had followed me around for decades, and I had some 2x4's (you know the 1.5"x3.5" pieces of wood that are dimensionly inaccurate). A little table saw work to cut seat slats out, jig saws for curved seats (my butt is round), miter saw to cut the feet angles, and a drill press later :

It works like a champ, though I probably out to have sanded the inside of the holes first for a less "tight" fit. I have to switch mindsets on "close enough" and stop thinking in thousandths of an inch.

Made a demagnetizer based on the suggestion from @woodchucker . Mine has 6 12mm diameter x 3mm thick rare earth magnets sunk into some 2" OD delrin. Used my dividing head vertically and nearly ran out of Z on my PM24. Used delrin rod as a plug for the magnets and made it a press fit to the holes. I then turned off the plugs. Installing the magnets was interesting. At first I tried installing one N up, then installing 2 holes away N up. This didn't work. By the time the magnet got to the bottom of the hole it had flipped over to S up. So the technique is to install the magnet the next hole over, the opposite pole. The fields will keep the magnet in the correct place.

I will make the "chuck" out of some aluminum tomorrow. Making the plugs took a lot longer than I thought it would. First couple took a while, but the last 3 took no time once I got the hang of it. Although totally unnecessary, I bought a brass washer and brass SHCS in 10-32.

I swear magnets have a mind of their own! (and smarter than a few folks I know too!

Wobbly great mind think alike! Just finished mine an hour ago. My was inspired by winegrowers recent post. I will be making this available as a kit at my store

Started to look at how to machine down to size the backplate for the 4-jaw chuck... This one will be one dirty task... Just testing the setup and figuring out the speed and cutter to use, there was iron dust everywhere! I will need to use a respirator, face shield, cover everything around the area...

One project I wished I could just move the lathe outside to do it
