Machining Axles - Tracked Amphibious Vehicle Build Ep. 6

Machining & threading custom axles and turning flanges in the lathe from 47 mm / ~2" solid round bar and 12 mm / 1/2" steel sheet so I'm able to attach the 4x108 mm bolt pattern 14" steel rims / drive wheels to the tub of the tracked amphibious vehicle. Again, the plasma cutter is still on hold and thus I'm stuck using angle grinders again. The custom made wheel hubs I turned and MIG welded in this powertrain are sealed from the outside environment and preventing water from entering the hull / tub of the all terrain vehicle. The other wheel hubs are bought ready-made and already waterproof from a local trailer shop and will have six 4x100 mm bolt pattern Opel steel rims & tires as idler wheels. These however will not penetrate the hull of the tracked vehicle. To transmit the power from the skid steering unit I fabricated and shortened from a LADA 2101 / Fiat rear axle with disc brakes on it I'm using tractor PTO parts and joints so I can lift the unit up and move forward in relation to the center of the rear wheel hubs. This will increase the clearance of the vehicle and makes it possible to remove and repair / or replace the entire differential steering unit completely if needed. This project will continue with fabricating the undercarriage, idler wheel axles and the tub itself. Stay tuned for more next week, make sure to watch the previous episodes in this series, subscribe to be up to date with new videos, comment and share your thoughts and ideas, also share the video if you liked it. Thanks for watching! Oh yeah, I completely forgot about the rough 3D model I sketched up in a CAD program I wanted to include in this video so if anybody wants to know what I am actually building feel free to Google the title "Tracked Amphibious Vehicle" and you'll see what I have in mind. See you next time!
