Hi Naveen.
I was playing with them earlier this month. I epoxied some .032” diameter steel rod into the keys to make them operate magnetically. They operate pretty good with the steel inside. Since I know they work magnetically, I think I’ll solder the steel rod into them. I also tried some mini ball bearings instead of steel rod, but the rod was a better solution.
I dipped the couplers in the photos above in blacken-it. I also used neo-lube on the operating parts to blacken and lube them.
The only tool I used to assemble them was a sanding stick to burnish some parts. Assembly was pretty easy. There are 4 parts and pretty much only one way to put them together.
The double shelf E couplers I assembled worked great on the bench, but I haven’t installed them onto a car. The coupler draft gear pockets work well also. The opening in the coupler pocket is pretty narrow, so these will probably only work on broader radius turns.
I experimented the F couplers and the lower shelf E couplers, but had trouble keeping those together. I’ll have to work some more on those varieties to figure them out.
Overall, I like them, but honestly haven’t really put them to practice with any real installation and real use.
