Houndbot progresses

All four new shocks are now fitted! The tires are still deflated so they look a little wobbly. I ended up using a pillow mount with a 1/4 inch channel below it. The pillow is bolted to the channel from below and the channel is then bolted from the sides through the alloy beams. The glory here is that the pillows will never come off. If the bolts start to vibrate loose they will hit the beam and be stopped. They can not force the pillow mount up to get more room because of the bolts securing the 1/4 inch channel to the alloy beams coming in from the sides.


I'm not overly happy with the motor hub mount to wheel connection which will be one of the next points of update. Hopefully soon I will have access to a cnc with a high power spindle and can machine some alloy crossover parts for the wheel assembly. It has been great to use a dual vice drill and other basic power and hand tools to make alloy things so far. But the powerful CNC will open the door to much 2.5D stuff using cheapish sheet alloy.

But for now, the houndbot is on the move again. No longer to the wheels just extend outward under load. Though I don't know if I want to test the 40km/h top speed without updating some of the mountings and making some bushings first.
