RIMAC Valve Spring Tester

 

 

Manufactured by: Rinck McIlwaine Company.  I can test valve springs for pressure at installed spring height, and cam-open position.  The arm can be locked to test spring fade over time.  Tested....it works perfect !  The heavy cast iron base keeps it put when testing springs.  It looks to be made in the 1930s or 40s???  I'll clean it up and paint a sturdy cast gray shop color . . . Vintage tools.  Made in USA.  Restoring vintage engines with vintage equipment.
