Sinds i made piece with my printer again after some heavy discussions and threads....
I am making some bogies, i was not pleased with the bogies i could find on thingyverse so i used 4 donor stls.
The wheels are completely remade/redesigned/makeover to achieve the g1mra standard.
Well:
Lets start with the axles.

In the mean time the printer was done, 4 times a 8 hour print:

One print was with axles and one print was without axles to maintain quality..

Yes nobody have to mention that i must clean up my working benches

I made the hole in the wheel just tight enough that the axle is true and must be forced into it, for obvious reasons of course.
It is a simple 500 kg arbor press, a vice could do the trick as well(least preferable a hammer)

Was cutting some simple copper wire for fastening:

Again a very tight fit.

The couplers must move freely that why the extra bus.

.There are 6 more bogies in the making so i have enough for now to experiment with the frames on top of them
I hope you enjoy all this.
Will be continued....
With best regards Igor

why did you put the extra pivot to the coupler? Also are you going to add a coupler centering spring?

The axle tips look pointed, did you make a conical depression in the sideframes?
