Hi Chad,

My name is Dan Bush and I represent Sanders Prototype in the central
U.S. I am familiar with Cummins (my favorite Diesel engine!) and can see
how an Actua would be a very good RP tool given the size of some of your
parts. But I would think you would also have some parts where you might
need better precision which is where the Model Maker II fits. A side
benefit is the castability of our material. It works great in the
traditional lost wax process.

Thanks for your consideration. If you aren't familiar with Sanders we
have a web site If you have questions please
give me a call at 940-383-9428.

Best regards,

Dan Bush
