Thanks John, Abraham, Don, David D, John B, Shipto Next job is to work out what to mount the bits to. David D - it's a TVR Vixen - currently in bits. I took the body off at New Year so the body is alongside the chassis so I have very little space to work. There's more pictures on a rather outdated website at http://www.hockerley.freeserve.co.uk/ Russell |

Stripped the galvanizing off of some thinner tube, and flattened a piece: |

I drilled and filed a hole slightly larger than the cylinder bore in the bottom head piece, then super-glued it down in correct position on the cylinder temporarily. I then drilled the valve opening from underneath using the valve sleeve as a guide. Then I ground a steam port between the valve hole and cylinder hole. Finally I marked and drilled the cover screw holes through the head and into the cylinder flange, using a tap size drill for 4-40 screws. I did all this to make sure everything would line up after I brazed the second layer of the head on. It would otherwse be hard to locate the cylinder bore hole correctly once brazing was finished. |

I rapped the lower head piece on edge with a hammer to shock-break the super-glue and removed the piece from the cylinder. Then filed off the glue. Super glue can release cyanide if heated -- as when brazing, so I'm quite careful to remove it whenever I use it as a temporary clamp on metal. Then I cut the thinner flattened sheet to rough shape with a hacksaw and filed it down until it was just a little smaller than the bottom head piece. The small step allows easier brazing. I clamped both clean pieces together: |
