[SEL] Patterns #5

[Curt]

Well guys, this is the last of the 5 patterns on the Stickney conversion 
project. This documents the pattern making work to create a new funnel 
that sits on top of the water hopper on a 5HP Stickney.

You'll see I only created the portion of the funnel that is visible. I 
choose not to cast the intricate details that extend down inside the 
hopper below the waterline. In my opinion that part was over engineered. 
Anyone really know what that was for? I can only assume it was intended 
to get cooler water down low when refilling the hopper?

This was the first poured core box I did. Knowing the low volume of 
cores to be made (perhaps 1 part) I tried to keep the cost low by using 
plaster. Don't think I'll try that again! There was more damage than I 
liked when removing the core plug. This meant a good deal of patch work 
after to ready it for the foundry. The good news was that the core plug 
came out in one piece. At least it can be reused if another core box is 
needed.

The complete series of 5 parts can be found on this page:

Hope you've enjoyed them.
