Re: PO 16124 Brass Scales

We received the rules today. Thanks to you, your staff and Whittam Precision Rules plant for your help and excellent service.

Dear Sir,
     As mentioned we received your "great rules" earlier this week.  I started working with them last eve.  I was very impressed with the overall "quality control"  I mic'd them all to see if the thickness was even, then we set them up for "warp and twist" with a dial gauge attached to a sine bar.  This was remarkable!
     ...Many members were very impressed with the "OHIO BAMBOO ROD MACHINIST org." engraved.  Your company did a fantastic job.   ...

Thank you,
Timothy M. Cartwright

...Thank you for enhancing our Tenth Anniversary of the Heritage Society of Swedish Covenant Hospital - Galter Life Center.  Your ruler gifts stole the show  - by any measure!
     Jim joins me in congratulating you for a job well done. We wish you all the very best in your future endeavors.

Please pass on my greatest appreciation for a job well done on the fabrication of the two CNC gears.  They worked out very well.  Schlenker really helped us avoid true disaster.  The gears arrived just in time as advertised.  My compliments to all involved in the project.
Best regards,
John Diebel
Vice President
