makig rear part 4

To connect rear folk and middle rectangulr, Attaching Brass plates are needed.]
At first, I drew 36 x 70 mm square on graph sheet and cutted them then grewed on Brass plate and sawed.

 To adjust ment the width fit inside of the middle rectagular, hand grinder and hand file were used. The angles of inside are a little round, So to fit more perfect, The edges of the brass plates were filed.

 Basicaly, rear part fits on under face of inside the middle rectangular, So the seam joined face is used to upper side.
Then, to lost brass plates, The hooks were made by welding.

 

 They were grinded to the same height with the thickness of brass plates.

 The brass plates were grinded to fit the hooks, however, when the rear part and middle part are connected, the rear part should move smoothly.

 The rear parts putted in the middle rectangular.

This is nutral position. The next photo is most heavy weight position.

 The next task is boring for suspention.

Fine.
