Step 1: Transfer the sign template to wood

Step 1.1

Transfer using a copying wheel (Sewing supplies) or with copy paper the outer contours of the curved parts from the drawing to the plywood.

Then saw out the individual parts using the jigsaw in conjunction with a curve saw blade. Regrind inaccurate or wavy areas in the contour.

Step 1.2

Broadcast for the individual parts that are required twice, the outer contour with the first part on plywood.

The same parts are clamped together and still once with a hand sanding block and coarse sandpaper, P80 grit, sanded on the edges.

Step 1.3

Be for the seat four equal arches made of 18 mm thick birch plywood cut out and glued together in width. When the glue has dried, you can bring the seat into its final shape with a rasp and file or an edge grinder.

Step 2: Saw out the frame from the wheel

Step 2.1

The positions of the drill holes are marked on the frame and fork parts and the positions of the steering attachment and struts of the fork are marked on the inner surfaces.

Drill into the individual parts of the frame and fork the holes for the screws (ø = 3.5 mm) and for the axles and seat mounting (ø = 8 mm).

Step 2.2

Saw the struts of the fork and that of the frame with a table or circular saw on the multifunction table. Mark the drill holes on the struts and drill the mounting holes (ø = 8 mm) for the fork.

A slot must be cut in the seat post for height adjustment. To do this, mark the slot on the board and drill a hole (ø = 8 mm) at the top and bottom.

Step 2.3

The The gap is sawed out with a jigsaw. There is a cover on the front of the fork. A decorative hole is either drilled in the middle of this cover or a cat’s eye can be attached to it. A hole (ø = 25 mm) is drilled for the handlebars at the upper ends of the fork.

3rd step: sanding and gluing

Step 3.1

Round off all edges with a hand sanding block or an edge router. Sand the surfaces with an orbital sander, final sanding grit P 180. Glue the struts of the fork to the front cover.

The individual parts for mounting the frame are ready for assembly. Specify wood glue on the connecting surfaces.

Step 3.2

First brace one side of the frame with the struts and screw the connections (Spax 3.5 x 30). The second page is clamped, aligned and screwed.

The frame is now assembled and can be set aside to dry. The two boards of the fork are connected to the struts in the same way.

Step 3.3

Three holes for wooden dowels (8 x 40) are drilled in the upper narrow surface of the seat post. Insert dowel tips into these holes, align the saddle and push it down. On the underside of the saddle you now have the impressions where you have to drill the dowel holes.

4th step: Mount saddle

Step 4.1

First glue the dowels into the seat post. Enter enough glue in the dowel holes in the saddle and on the connecting surface and clamp everything with a clamp. In order to be able to paint the individual parts better, the surfaces are painted in color or transparent before assembly.

Step 4.2

Make sure that with every screw connection, always where the machine screw meets the wood, a washer comes in between. Put the fork and frame together and push the two fastening screws through the holes. First put a washer on the screw and then unscrew the stop nut.

Step 4.3

Cut the spacers for fastening the seat post with an iron saw. Either an iron pipe or a spacer sleeve (M10 X 30) can be used as spacers. Install the seat post as shown in the drawing.
