Before, I made the frame of seat from iron sheet which thickness is 1.0 mm. But after riding 1600 km, I got first its breaking. Then after 3700 km, I got it again. Thin iron sheet is repaired easily, but such problem often happens.
So I decided changing the construction of the sheet.
I bent iron tubes which diameter is 12 mm.
I used pipe bender.
I made large curve by bending a little at many points.
I have to wait left material arriving.
I made two spacer for front part.
Then I observed my second python. I found two things to improve.
This is one of the edge of handle. It easy to get the rust. The shift lever should be moved.
This is stay for seat. I don't know what's the white staff. It can be sawn only here. It isn't easy to make this part. I better change the construction.
