Chris, where in Germany are you? I frequently go to Leipzig for work as I do flying for DHL, would love to see your work up close. Also, I know you’ve mentioned it before, the way you mount the drivers to the axles, what’s that called?

Hello Steamchris,
Some important progress with your J, congratulation! The day of it's initial first run on air is in sight now, isn't it.
For better understanding the construction of that Timken crosshead for both the A and the J, there are some more photos.
Maybe some other modelers are interested in that careful and proven construction of that Timken crosshead with (clamped) ball bearings?
Both easy to mount and disassamble without any backlash. Grease my be pressed between the bearings by means of a small chanal once a year.
