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.
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.
"All kinds of Huffys in the dump, there's a reason for that" I used to own a Huffy when I was 6...The Huffy Bandit. Black & Gold. Quite possibly the ugliest bike ever produced. I did love my Green Machine though. That was fun!
Thanks for making my custom poison Pot with copper top and the small Bongo. Now all I need is a 8X10 photo signed by you my friend...this will go up in my shop.
you are correct that caster directly affects the tendency for a steered wheel to return to center, but you may also find that changes in the toe in/out will also have a direct effect on the steerings stability (with the affect noticed more as speed increases). just a little something else for you to consider.
dialing in the spring makes the shock stiffer it doesnt change much of the caster. i used to race bikes for to sponsers growing up and never had adjusting the spring tension change the pitch of the front end unless you made it so loose that the bike warped. I dont doubt it help the steering but its because you took out the excess bounce.
Tinny, you have that steering geometry down pat. I'm impressed with the fact you applied Ackerman's law. More caster will give you more stability. Hi Mary!
Tinny ..if you need to change the caster more without lowering it you can heat the beam that goes from tire to tire and twist it i used to bend I beams on trucks to aline them and the only way was to bend them..Dave
great video...specially how you explained caster ...

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!

Can't you connect 2 chains together to get the length you need?
