[SEL] Re: [HerculesEnginesGroup] J mixer for 5 hp herc / posted to SEL.

Rich,
One hell of a project you have just finished! I am going to copy this 
over to the Stationary Engine List because many will find this project 
very interesting. I hope you would consider joining the SEL in addition 
to the Herc List you are already on. You can join with this link.

I'm assuming you used the steriolithography technology or something 
similiar to make your mixer from the solid model you drew in CAD. By 
having this capability you are in an excellent position to go ahead and 
make a pattern and core box and cast yourself a brand new cast iron 
mixer. You'll just need to scale your pattern 1.0104 X and add about a 
2" extension of the ID of the mixer for your core to be held in.

Having this technology available puts you in the enviable position to 
easily make patterns for your replacement parts for your antique gas 
engines. Core boxes are particularly difficult and this technology would 
greatly simplify the process.
Hope to see you on the SEL soon.
