Well, the last two parts I needed have arrived from Bill Cozzi so I now have zero excuses not to work on the hack I bought over a year ago (November 2016.) Question for the group: I know there is a formula that the car wheel needs to "toe in" in order to turn safely. What I was thinking of doing was making a kind of inexpensive "jig." The jig would consist of two long furring strips or 2 x 2 pieces of lumber, as straight as I could find them. One would be laid along the left (outside) of the bike wheels and the other would be laid along the outside of the chair wheel. The wood strips would be attached to each other by pieces of string. The string at the front would be slightly shorter than the string at the back so as to "toe in" the wheel on the car. My question to the group, then, would be how much, in degrees, should the toe-in be? And then how do I translate that angle into linear measurements for the strings? I'm assuming I'm not the first person who's thought of this so any help would be appreciated. FWIW the pusher is a 2002 Triumph Bonneville 790. As for the car, well, it looks exactly like a Kozy to me but according to Bill Cozzi, it's actually an Inder. As far as actually assembling, I will probably have some help as I assume I'll need to hold the bike vertically off the side stand in order to attach the brackets. Any input as to how tight to torque the bolts? Two of the four attachments are going to "wrap around" parts of the tubular frame (one on the front above the oil cooler and one on the rear next to the side cover.) The other two attachments (the low front and low rear) were custom made, one goes onto the flat bracket between the front frame rails and the other attaches to both center stand attachment points.
