Engineering notes
Notes for buyers and design engineers: tolerances, materials, finishes and getting parts made on time.
Choosing a material grade that is easy to buy
Common grades arrive in days; unusual ones can add weeks to a lead time (sample note).
Why we deburr every part by hand
Sharp edges cut fitters and damage seals; the bench op on every route card is there for a reason (sample note).
