A photo showing the beginning of
the rear peg and brake lever mounting for the right side of the bike. Metal is 1/2"
thick 6061 aluminum plate. This is the raw shape before finishing of any kind. I
experimented with 1/4" 6061 and it just wasn't going to be rigid enough after it was
drilled full of holes. I also can use the extra thickness to support the pivot for the
rear brake lever. The way this piece will be bolted to the frame will also add some
rigidity to a crucial area of the chassis. This will become clear as additional photos are
added to this section. |

Stage two, the mounts are drilled
and mounted to the frame. Small tabs of 1/8" thick steel sheet are welded to the
frame tubes and tapped to accept 1/4-20 mounting screws that pass through the peg mounts.
Peg mount screws are counter sunk into the mount so the riders foot does not get hung up
on them, it also makes for a neat appearance. Notice matching peg mount on opposite side
of bike. In the photo the three smallest holes are the mounting screw locations. (Notice
the design change from the photo above, this was necessary to lower the position of the
rear pegs) |

This shows the basic right side
peg mount. The arrow shows the hole in the brake pedal pivot shaft that takes a cotter
pin. This pin keeps the shaft from sliding out of the bushing that is pressed into the
mounting plate. The bushing is 3/4" inside dia. and 7/8" outside dia., it's a
nice press fit into a hole drilled with a 7/8" bit. Holes for plate mounting are
counter sunk to keep the riders foot from hanging up on them. The brake pedal in the upper
left has yet to have the actual foot pedal added, which will be just be a 1 1/2"
section of 1/2" dia tube, just enough to get a toe on as the back brake is seldom
used on most bikes. |
