Here is another little project I've been meaning to do. When bucking up larger logs to be split I sometimes misjudge the length. That and when called upon to do firewood for others who need it shorter I mess up. Got a magnet from HF for around $7.00.
The way they made this is that the nut is trapped inside. Instead of sticking a screwdriver in there to tighten it, I'll just make a self locking strap with a 1/4" 20 thread.
Found a piece of scrap with a threaded hole all ready in it. Just cut and ground it so it would slide in the slot.
Got a length of stainless rod from the steel pile and spun it down to put some 1/4" 20 threads on it. I premeasured the length to 22" to the edge of the magnet(far side)
Took it out and threaded it. I'll put a nut on the outside to act as a lock nut.
Here it is all together and locked in place. I also spun a relief and marked it in red at 15 inches. This way I can get that length right with the same tool. You can mark what ever length you need this way.
Here is a close up of the cut in relief and painted red marker.
Magnet is plenty strong and just snap it on and you have a quick length guide.
Quick and easy and have really like how this has worked so far.
