Finishing the frame head

Now the big hole in the frame head it ready, it's time to clean up the rest. There is (of course) a lot of rust. It looks like there has been a lot of water in this area. A lot of rust pits can be seen at the picture below.

The first thing I did was welding a few small holes (after sandblasting them). Next came a lot of sandblasting, grinding with the angle grinder and using a wire-brush. Here is the work in progress

You can see an old repair at the left of the pictures. I gave it a fair beating and it didn't budge, so I guess it's good enough. Not all the rust in the pits could be removed (within a reasonable amount of time) but I hope the zinc spray will neutralize for the coming years. After cleaning all the dust and using thinner to remove some compressor oil spray it was time for the zinc.
