I thought if I put the wick in there I would know where to find it in the future. :). |

Disaster looming! Not much done the last couple of weeks as it has been too cold in the garage. Had a look at it today and noticed the threads tapped into the cylinder to attach it to the standard appear to be breaking up. The bolts that were originally all a good tight fit are now very lose. I have been very careful not to overtighten the bolts so am not sure the cause. The plans call for an imperial thread, but I used metric. Maybe the thread is too fine to hold in cast iron? It is happening on all 4 tapped holes. I can not drill out and go up a thread size as there is not enough metal, so need another solution. I thought maybe rather than using bolts, I threadlock some studs in, but suspect that threadlock may not withstand the heat. Anyone else with any suggestions as to why this has happened, and the best way I could overcome it? I really do not want to have to build the cylinder and piston again, especially as I do not know how to avoid the same thing happening again. |
