Connecting middle and rear part

To connect middle and rear part, It's needed boring for screw.
When I started making my python, I had mistake about it.
This time, I make smaller hole and widen with hand file.
At first making.
Next cramping and drilling.
 Then widen with file and adjust the diameter and the position.
 For suspension screw, the upper side hole is larger. It's about 20 mm.
Side view of the suspension.
 The rubber and circle iron plate are used.
2 washer are welded both sides.
Then grinding the surface to be smooth.
 Assembling.
The screw was used for rear before. then cutted the screw.
Ofcourse filing.
 done.
Over view.
The next task is welding the other front folk for seat.
 The front hub was welded on the edge of middle rectangular.
 The welded looks niecest ! However,I cleaned the flux.
Actually It wasn't enough. I repeated welding for sometimes to both front and back side. I had mistake which is bored the hub and I covered the hole with welding.
When 2 parts which is defference of the thickness, It's important to get it which is thicker or thinner, I think.
 Done. Side view.
Front View, Fine.
