Hi Lads :wave: Well :proj: has struck again ,,,,,,,,, Now that most of my machines are sort of done and the furnace is up and running , i thought i better start yet another engine project , well i wanted some excuse to do some casting , I bought the plans for the R&B Gas engine a few years back because its a nice big-un ,,,,,,Then when i looked at the plans i found out i could not cast the parts due to the size of my old furnace :bang: :bang: :bang:. So this afternoon i made a start on the patterns for the bed casting , The bed plate as drawn is some what plain ,so i re drew the bed adding a bit more detail , it should look like dis , i hope Progress so far ,,,,,,,,,i only use the straightest / close grained MDF for my patterns . Regards Rob |

Im watchin ... Im watchin..... mdf is crap to work with isnt it.... 'specially that 'straight grain stuff'.... Thats a complex plug mate, you gonna pull it apart for us so we can see up under its skirts? I find this part fascinating... visualising something so you can make it removeable from the sand is not always easy. In essence you are working to create a reverse image.... I think you have to be a bit of a nutter to be able to do it well.... sort of twisted and axxse about. Hurry up n fire up the furnace... :clap: :bow: :beer: |
