I've been plugging away at the axles of my third truck. I've been tinkering with the two axles over the course of the last month .

Anyway I tried several variations of bevel gears in my work to get these axles in order. First was the spiral bevel gears I had on hand but there was too much I needed to do to/with them
to get them to work and when that was done they didn't run in a manner I wished. Next I purchased spiral gears for a Axial truck variation and again and
more so there was too much to do to get them to work the way I wanted and the results were not satisfactory. So I broke down and purchased
appropriate bevel gear pair sets from Maedler in Germany. Gads I love their stuff! And their prices to my mind are very reasonable but they always insist on
DHL rocket mail and while it's great to get them in a few days it costs... Not being in the mood to write a lot (see above) I'll let the photos do the talking but this is a work in progress. You can see the bevel gears, meaty pieces,
the reduction gears and the keyed sliding lock that will lock left and right half shafts on demand when finished. According to the documentation this is a mechanism in theory similar to
one used by NAG-Bussing until the mid 1960s for heavy trucks. In the two rear axles only two outer wheel pairs are to be driven under normal driving conditions: the left side on one axle and the right
pair on the other. Once locked all four pairs are driven. Turning must be problematic but the wheels are also to be driven by a planetary gear set in the inner hub. Jerry
