How do you know you get a good seal at the exhaust port?
The only way to really know is to take down the heaterbox and look for soot on the copper gaskets. But by then you will need to anneal the gasket again and hope that you get a good seal the next time you mount the heater box too.... Tips and tricks are most welcome.... |

I flattened the stub pipes last summer using a piece of thick milled flat piece of steel and 1200 grit sandpaper. With one stub completely flat against the steel piece the other had a max deviation of 0,1 mm so they should be ok. My sealing issues seem to be from the the fact that the centre of the stubs are too closer together.
Will have to see what I can figure out to fix it today. This is how I solved the leakfinding. Made up a 3 mm plate and brazed two male compressor fittings to it. Set the pressure to 0,5-1 bar and just connect the hose to the cylinder I want to test.... |
