Project Silver Fern, Malossi 210, cylinder and piston milling part 1

Today we are preparing the Malossi 210 for installation.

So that the full depth of the original overcurrent ducts in the motor housing can be used, the windows in the cylinder base are expanded.

Remove the depth of the channels and transfer it to the cylinder base.

The window is first roughly cut out with a cutting disc.

It is important not to go to the final size, there should not be any sharp edges and corners. In the cylinder base in particular, it is important that the windows have a radius, otherwise cracks can quickly form out of the corners.

The coating in the corners of the raceway is now removed so that the coating in the raceway is not damaged in the next step.

For those of you who are tenderly strung please do not look at the next picture.

Here the cutout is removed with a slight * tick * of the hammer.

The resulting window is then made pretty.

The whole thing all around.

Tomorrow we will tackle the ducts as such together with the motor housing.

That leaves the piston.

All black marked areas are removed and then smoothed.

now about 20gr. the piston looks lighter like this.
