可重复的木制自行车

The idea of this project is to make a wooden bike that you can download and assemble like an IKEA chair. There is already a lot of wooden bikes on the web but if you are not a professional woodworker or you don't want to spend month refining the parts until they would fit together, then the result will not look like the wooden bikes in design magazines...

It took me 7 days to make this bike (without the design) but I never used a CNC router or a hand router before. InFablab Moscowwe have all these machines and I was looking forward to having an opportunity to use it. So now if you wand yours, find a place with a CNC router (fablab or makerspace), cut the parts according to the files, cut also some lumbers and assemble it.

工具

• CNC router
• 手路由器(25毫米球头立铣刀和倒角或射线on mill)
• Jigsaw
• Pressdrill
• Laser cutter (optional)
• Chisel 12mm

Material

• Plywood (15 and 18 mm)
• 木材（40 x 20 mm：200,480,490,556,556,620,620 mm）和（30 x 20 mm：500,500,400,400 mm）
• Cylindric lumber, diameter: 28mm length: 260
• Aluminum 5mm 20 x 40 mm
• 叉轴承
• Pedals with bearings and axle length: 68 mm diameter: 34mm
• HTD 8M 1440皮带
• Tire tubular 22mm
• 车轮轴和轴承长度：140mm
• M4螺钉和螺栓（40,50,70 mm）
• 5 times M6 x 100

Download the file and cut the parts. For the lumber, cut the length:

• 40 x 20 mm：200,480,490,556,556,620,620 mm（斜切以90度切割）
• 30 x 20 mm: 500, 500, 400, 400 mm (complicated cut: see the files named "baseArriereBas" and "baseArriereHaut". Detailed explanation later)

我决定逐一粘在一起，而不是堆叠一切，因为它更容易控制对齐。

然后我打了街区并在每个边缘制作人造丝。

不幸的是，我必须用胶合板调节木材厚度。我用框架和凿子去除每张脸上的1mm。

The back lumbers have complicated cut so the simplest way to do it fast is to laser cut the shape from the files named "baseArriereBas" and "baseArriereHaut" and report it on the lumbers. Then I cut with the jigsaw and finally sanded the last imperfections.

I doubled the down lumber to increase rigidity, it is now 40 x 40 mm. I recommend to do it also on the horizontal lumber.

For the wheels I used a 3d printed shape to ensure alignment. All these discs have 15 mm thickness except the rear right ones who have 18mm (pulley side).

I did it with the jigsaw but you can probably mill it with the router.

您需要钻阀门孔并制作轮胎槽。槽的深度必须为3.5毫米，以适合622毫米轮胎。我使用了25毫米钻头（球端），因为我找不到22毫米，但它似乎是完美的。我用两个通过的插槽点击：一个从一侧和另一侧的另一侧。我用了一个“空白”泵来膨胀轮胎。

Finally drilll the rear wheel at 6 mm (use the shape "chablonTrou" as a guide) and add 5 M6 x 100 screws.

用34mm钻头钻叉孔。该位置距离前部30mm的中心。

Then drill all the screw holes at 4mm and assemble the frame with glue and M4 screws. Then add the bearings.

我用激光切割机制作滑轮，但您也可以在15毫米的胶合板中铣削它。我把三个5毫米的层粘在一起。然后将它们安装在踏板和后轮上。

You also need to add rings on each side of the front pulley to guide the belt (not on the image!).

将下降部分切割为图像。胶合圆形木材和两个40 x 20木材。用车把高度调节轴承的间距。

以70度角在所需长度下切割40 x 20木材。制作三角钢筋并粘合它。最后在马鞍和木材之间添加木螺钉。您还可以将马鞍塑造给您的形态。

Add coating (pain, lacquer or epoxy) to make it waterproof.

我还没有这样做，因为我希望能够在这个早期的测试阶段修改我的设计。如果完成了一些重大更改，我当然会在本文中通知它。
