HEHEHE.. Finally an little update!!
Had found some sparetime on second christmasday (before the family-stuff begun).
At 10am got the drill and angle grinder together to start working, with the following result:
First begun to make al the welds of the napoleonhead and the chassishead "clear". Than noteded soem measurements.
After that drilled some spotwelds and cut the napoleonhead of.
Then cut away the other pieces and that givese this result.
After some grinding it looked like this.
The underplate of the chassishead is temperwarely on this place, as "mold" for the napoleonhead. After the napoleonhead is welded the hole underplate will be changed.
