Attaching mudguard and making seat

To fix the position of seat, it's needed attaching mudguard.

Before that,  I added some washer between bended crank and middle rectangular.
By that, the crank doesn't touch to the rectangular, So the form of the rectangular is kept.

To attach mudguard, a female screw is maked, the guid hole's diameter is 5 mm. The tap is for 6 mm.

The other side, just hole which diameter is 6 mm was made

The other side, Just hole the diameter 6 mm. The front wheel was assembled again.

Rear wheel also got a fender.

The front side of rear fender is screwed from underside. I think this part may be changed more thicker one.

Next, making seat ! These measurements for parts of seat are larger, so I used hand saw for that.

 I cut them roughly.

 Then finished with japanese traditional plane.

 The above photo is rough. Then following photos were planed.

 It may be hard to see the line drawn by pencil.

Good job. Then cramped smaller one and a rectangular for seat.

 Then boring, the diameter is 5 mm. these are screwed and cramped to upper crank for boring.

 Like this, The center hole of veneer works as guide to drill upper crank.

 Almost center ! perfect job. Then taking off only the veneer.

 Check the angle 90 degrees ! then masking fender and welding.

 Done.

 Assembling the veneer again. and mark the position for the belt. The position is more 10 mm front of rectangular for seat.

First, I tried making holes and cut with string saw. But the saw's blade is too wider.

 I needed the other way.

 This drill isn't drill. it's the end mill for milling machine.

Making long wide hole is easy with it !

At last hammock seat can be sawn. The distance of belt of bottom side is better more near. But this position can work support my hip,too.

The position of hub for seat may be too back.

Sitting shot. 26 inch folk is bigger. The head rest may not needed.

No, It's needed.
Fine.
