Introduction: Wood Trike

Started in April of this year, the construction lasted for half a year until the end of October. It is not possible to list all the work steps that were necessary during this time. Therefore I am allowed to present my project in a few and hopefully meaningful steps.

Step 1: Cutting

The construction began with a waterproof glued 9 mm thick birch plywood board. I divided the plate along the middle and put the halves on top of each other and fixed them. On painter's crepe then recorded the contours of the straps and sawn with a jigsaw with a slight excess. Then ground to a finished size with a slowly controlled angle grinder.

Step 2: Assembling Chassis

Next, I've dealt with the load-bearing blocks. From the sawing waste of the belts coarse blocks glued together and milled on a Einhell MBF with cross table in shape. The
size of the blocks, I have chosen emotionally so that the safe force entry is guaranteed by the blocks in the straps purely on the glue surfaces. Exception: The two blocks for the front wheels are additionally connected at the bottom with carriage bolts with the reinforced cross strut. The holes in the blocks serve to reduce weight.

Step 3: Next

The next steps
were the installation of the frames, evenly distributed between the blocks every 200 to 250 mm, placing the bottom bracket block with glued-BSA sleeve, the conduit installation for lighting system and cables and finally gluing the Seitenbeplankung from 1.5 mm thick Aircraft plywood with the upper and lower belt.

Step 4: Sanding and Final Body Works

After sanding the surplus 2 times glazing the frame and
Attachment of the first components such as wheels, steering linkage, tie rod and crankset. In the rear area, I've cut two openings to create storage space. Unfortunately, I have not documented the production of the seat and the seat suspension with photos, but also the seat cheeks are sawn from the remains of the 9mm plywood board. The seat cover consists of crossbars, 10x10 wood, embedded in the cheeks. Finally, the whole seat unit painted black for optical reasons.

Step 5: Steering, Brakes, ...

Here is a detail of the front suspension. Made of M12 threaded rod, 12 and 8 ball joint and aluminum knuckle. The 12-ball joint is designed as a fixed bearing and the 8-joint as a floating bearing.
During the test drives, it quickly became apparent that this suspension was not stable on track. Therefore, the stub axles have been connected at the bottom later with a pull rod.

Step 6: Lightning, Etc

Laying the drive train, lighting system, brakes and seat mat are the crowning glory to make the trike ready to drive.

Step 7: Tires

Wooden wheel discs were not missing at the end of the project. As material I decided for birch veneer, just to get some practice in veneer processing.
Black reflector film on the edges of the wheel discs complete the above title photo.

Step 8: Finish
