Thanks for stopping by. Enjoy my site.
Log Cars
I wanted some log cars for my Shay to haul around.
I found some log skeleton kits from Don Winter and built a half dozen of them.
They are nice kits with great castings and neatly cut wood for the frame, plus they came with trucks and wheels!
I originally glued the logs in place using silicone cement.
However, I also wanted to pull some empty log cars, so I really needed a way to make the logs easily removable, yet also be secure when running loaded.
I purchased some diametrically magnetized cylinders ( 1/8” diameter by 1/4” long) from KJ Magnetics.
Diametrically magnetized means they stick to the sides, not the ends.
I discovered that the brass chain I used was not pure brass at all - in fact the magnets stuck to it so I could use the chain itself to help secure the loads.
I cut some 1/8” inside diameter aluminum tubing to act as a holder for the magnet.
I punched an end of the tube to not only compress it, but act as an attachment point for the chain.
