Nice clean solid looking castings

I have done a bit more casting with the yellow brass this time it went much better, and I also made a proper pouring holder for the crucible. It seems the second time there isn't as much panic!  :scratch: Although I did picked up a spoon type ladle from the dollar store for the dross it lasted about 4 dip's. :Doh: so I'll have to find a cast iron one or weld something up thats thicker.

I made two castings but carved out the gating fairly wide more than I really needed but I figured each piece needed a passage. The one on the left has two risers one on each end with a central sprue for pouring I think this may have pushed any loose sand towards the risers. The gating and risers weighed more than the castind did! :palm:

 

Here is one getting faced off.


The castings so far have not shown any real signs of blowholes or any other abnormalities.


I'm quite happy with how it turned our and had no problems with the zink fumes but I'm still looking around for a air system and some foundery gloves to take the heat.

just a quick update I ordered the piston rings and gland material from Stuart turner, they say it was shipped sept 3 via the post office almost 5  :palm: weeks now! I'm saying this hoping there is a packet in the box! Geordies do know about airplanes and how they are faster than a slow boat to china?  :D
