This is the infamous Walthers 90’ turntable kit I am currently constructing. I like a challenge and this kit had such a bad reputation I just had to build one.
At this point the bridge rotates freely and evenly, so 99% of the problems are solved. I had to turn the plastic bogey wheels between centers (using special tooling I made) on my lathe. It worked well but if I do another one I will use 1.5 x 6 x 2mm bearings for bogey wheels and cut shafts.
I have discarded the plastic deck and using real wood. You will see some printed circuit board ties installed to solder rail to. I will paint these black later to make then *disappear*.
See bottom photo for closer look at turned bogey wheels.
