Not hot enough Or burner not big enough, you really do need propane butain is ok for small jobs For the low melt SS you need a good 650 deg C or a dull red but it must be all up to temp. Remember the SS will flow towards the heat , therefor you controll the flow As a final point flux I use T5 it stays active longer in the heat and is more aggressive as a result when the joint is hot enough the flux will go clear and the joint will look clean, yes it's a bit harder to clean up but a soak in citric acid sorts it out Stuart |

A bit more time in the garage this afternoon, making the cam washer and two flywheel hubs. I will have to wait for the die to arrive before I thread them. A good chance to try out my new collet chuck. Don't know how I managed without one before. |

More work on the crank. Assembled with green threadlock yesterday. That stuff doesn't give you much of a handling time does it! My plan today was to drill through and threadlock in some 1mm pins. Confident this would be okay after doing a test piece, I managed to snap a drill off in third hole. :doh: Managed to drill/bash the broken bit out, but it all looked a mess once I had finished. A change of plan. The holes were opened out to 2mm and the both ends were countersunk by a small amount. Panel pins were cut to length and peened to fill the holes. The sides were then flattened off using a diamond stone. Not perfect, but disaster avoided. A shame I am a poor shot with the hammer as I have left some small marks on the edges. |

Ian At the risk of telling you how to suck eggs , when you cross pin webs do not countersink or do any work on the hole edges that way when you press in the pin and dress it off it will not be seen . Stuart |

That is the sort of advice I am on here for Stuart. Too late for this one, but I will know next time. Thanks. Centre now cut out and filed flush. I think I have got away with it. |
