| Darren:
Excellent thread, really nice to see the successful casting there :clap: |
| Artie:
I have intentions of building another twin at some stage so I ened up casting 5 brass cylinders (1 reject)... Take a look at the cylinder on the left, this is one month after polishing.... gee that was wasted effort... actually no it wasnt.. I had a blast... To get to this level I made a mandrel to hold the cylinder, the cylinder was roughly chucked up in the 3 jay, one end faced off and the bore taken to 24.9mm and then mounted on the mandrel. It wasnt taken off the mandrel until its finished. The mandrel was simply taken from lathe to RT in the mill and back when required. |
| Darren:
Couldn't you drill and plug the dimple? Be a shame to loose it .. |
| Artie:
Hi Darren yeah its been a fun project, more to go though..... I have one cylinder finished and have left the others in a semi finished state until I have all the components to seal them up (end plates pistons etc). |
| Artie:
Do you mean the sink back area? If so that was only a test piece in ali, it was always meant to go back into the pot. It didnt happen in brass which was the whole reason for doing a few test pieces in ali... casting that is really easy (in comparison..)... |
