[SEL] 3HP Hercules Jaeger Economy pattern and core box.

[Curt]

Tommy,
As promised here is a page on another pattern and corebox to make a 
piston for the 3HP Herc/Econ/Jaeger engines. The 2 photos at the bottom 
show the removable pieces that can be swapped, that make the rib that 
runs across the top of the piston. The pieces are held in with wood 
screws into the side of the corebox. After ramming they are slid out the 
side of the corebox.
You also asked about the gluing of the pattern halves. There is a 
picture of this in here as well.

Hope this helps.
