Thank you Jonule, I saw your achievement. Indeed it is not bad especially the idea of ​​using a galvanized tube of extraction already curved it is brilliant. I already bought flat steel sheet I do not know how to bend it so that it is homogeneous. Regarding the sprockets I have already looked at the bike side but the simple sprockets are rare if not you have to find an old bike which is not easy. At used bike dealers they want a fortune. I don't know if it still exists simple rear and front gables (bikes without gears) to buy. I'm going to look at decathlon but in my opinion they will take me for a fool. I already realized the axis with the bearings and it is 30 mm so I have to find either pulleys or toothed gables with a center distance of 30. If qq an idea or find them .. Thank you

as you feel!
but it is done on any bike in fact, it is everywhere, at the decehtterie etc ... it is necessary to extract the pinions and dislocate them!
so you have several!
I played with several axle / pinion parts from several bikes ;-)

for blades there is more simple: with PVC tube!
