HD Knucklehead (11)
LEGO Harley Davidson ”Knucklehead” motorbike, a Technic and System combination model.
About this creation:
As you may know I have a soft spot for vintage motorbikes, so to add a new model to my collection of bikes, I decided to see how a LEGO Harley Davidson “Knuckle head would turn out.
Drawings for this model simply consist of a sideview picture, scaled so that each 5mm equals one stud. Calculations starts with the available wheels, which actually dictates the final size of the bike, but I haven`t calculated the exact scale of the bike, but it`s somewhere between 1:7 and 1:8. Both front and rear wheels are the same configuration as with my LEGO V-Rod; The wheels consist of a 61.6mm Rim (# 2903), with 81,6mm Tyre (# 2902), outside this is another Tyre 94,2mm (# 88516).
Next step was designing the engine and frame. My biggest concern about the engine was the exhaust pipes. Flexible pipes are a nightmare to handle in LDD, so I omitted the pipes in the LDD design phase, but left a suitable space for the pipes to be fitted later in the building process. LDD is a grateful media, where everything stays neatly in place, no matter how many times you turn things upside down and back again. It was quite different when I tried to attach the exhaust pipes to the engine. The cylinders consist of various wheels/round plates stacked on a 4L bar which allowed them to turn. This was a huge problem when I tried to add the exhaust-pipes. It was fixed by tying the two cylinders together by the use of some plates with clip thus at the same time forming the carburetor. In order to keep the shape of the corrugated pipe forming the front exhaust pipe, a peace of copper-wire is inserted into the pipe. The frame came quite easy together because there`s no suspension on the rear axle.
The front fork has no working suspension either, but a “look alike” springer system formed by rods and corrugated pipes for springs.
Front and rear fenders are a further development of the fenders used on my previous bikes. Now with sides made of plates attached to the fender-arch with Minifig back plates. Hope you like them, I do!
The bike has quite a lot of shiny bits and pieces. A lot of these parts are spay-painted, mainly to keep costs low, but this time I have also used chromed parts from one of the chrome brick dealers, and they certainly add a lot bling to the bike. One of the best parts I`ve bought are the black-chromed Technic wheels forming the cylinder tops. The wheels are in fact Black but the peripheral edge of the wheel is shiny chromed, looking like shiny cooling ribs. A few other pieces have been painted, red and black.
Comments and criticism are more than welcome!
Hope you enjoy the pictures.
