  • great video...specially how you explained caster ...

  • @minibulldesign How did that little inverter welder work for you? Your welds look good.

  • gr8 work bro. u r a true engineer

  • I wish I could go to the dump and fetch stuff, but its illegal :/

  • A key comment should be mentioned with regard to true Ackerman steering. You welded a short tab that the tie rod end bolts to, on each of the recycled crank arms (now serving as steering levers). How did you determine how long that tab should be? Well, for True Ackerman (not near Ackerman, where tires scrub), it's length should be so that if you draw a line from where the crank arm is welded to the hub, thru the tie rod end bolt hole in the tab, it must intersect the center of the rear axle.

  • I knew all these principles in theory, but it was nice to see them in practice. I want to design a two-seater quad, and so I'm working through issues for both the front-end and dual-drivetrain/back end. By the way, I really like the kingpin-based steering handle.

  • Great Video! It's going to help me alot when I weld my steering components together for the trike I'm building. Thanks Tinny your videos are great!

  • camber,caster and toe-in etc!if you dont know what you are doing you better make those adjustable or you will cus a lot!(grin)is this made to go to irak ?it look like it could stand 2 bomb in a row!good job by the way doing this project!

  • Hi Mary! Hi Tinny! I had a 'bent trike at one time. The one thing I ran into with it was "torque steer". Very unnerving at high speeds! As you put pressure on one pedal or the other, the rear wheel would camber over causing the trike to suddenly turn resulting in the machine wobbling back and forth, opposite the pedal pressure. With the single seat boom and no panhard bar, you're probably going to experience this issue with your trike if you intend to go very fast.

  • High Mary, nice homebuilt bike, excellent class on  design principles of steering mechanisms
