BMW 'Go to Work' Special

My friend Martin is up to his old tricks again building a BMW Boxer up mostly for use as his commuting to work bike (he's put his Morris Minor project on hold for the time being) As he uses the bike all year round he wants a element of practicality about it using three spoke wheels for ease of cleaning. I'm not sure about the rest of it,but already due to the wheel arrangement he's had make up a disc carrier. The rear wheel would have been a long way out of line with the front so he's had a load of weld put into the centre so as to be able machine it to suit and then bringing everything back into line.
