@Johnbeere posted:Overall, your best route will probably be to cut the axles to length, and fit new 3D printed wheels onto them, using the standard Lego axles. You might be able to contact Cale or Glenn at BMR to buy wheelsets without wheels fitted to them, I think they'll probably help you out.
That's an interesting thought! BMR is already putting bushings in technic bricks, but their axle diameter is much smaller. The are set up for 4 wide between the wheels. If I change the width that no longer works. I would have to come up with a new brick spacing that does not result in excessive lateral play.
Also, I talked to the good folks at Kadee this afternoon. I got a nice education that the 805 or 806 is the coupler that I want for the best chance of coupling with existing o gauge lobster claws. Kadee even recommended playing with 1 gauge 821 couplers since the toy train couplers are so big. I should be able to take the BMR coupling boxes and switch the 743 size they came with to the 806. Then I can build truck assemblies that will interchange with traditional toy o gauge.
This is shaping up to be quite the interesting challenge.
