 when it came time to manufacture the 80"" diamter boxpok wheel for the PRR T1 #5550, gemini spent countless hours managing contractors to ensure the highest quality. much time was spent doing metalurgy to ensure exact match to original steel. These wheels had not been poured in more than 60 years.

 Here is an example of custom rough boxpok castings for a custom locomotive. we did final machining and added steel tires. patterns were 3d printed and wheels were cast from gray iron.

 We often manage a project from beginning to end. Here is an example of a brake shoe for a custom locomotive. we engineered a 3d printed mold, created wax pattern and had hard bronze shoe cast and machined/delivered to customer.
