today I put together the sprocket wheel.
I used the following items in addition to the alu cut wheels:
- piece of M2 threaded rod
- M2,5 bolt 8mm long
- M6 to 4mm part to connect the sprocket wheel to the motor
- M2 nut
detail of the connection piece
with a 6mm drill bit I started to make the holes bigger
then i used a 5,5mm drill bit to make the other holes bigger. I used a M6 steel bolt to thread the 5,5mm holes of the round plates so they would fit on the connection piece
then i drilled a 2mm hole in the middle of the connection piece so I could fit the M2,5 bolt in it to hold the last 3 round plates
thats how the front looks
the back side, after cutting of the excess of the M2 rod and adding the nut.
i decided to add 16 bolts M2 of 6mm to finish off the front
still 13 bolts to go
