				To anyone building the Zenith CH 640 from plans:
 
 After trying roller-type lightening hole flange tools with limited success, I decided to make my own flanging dies.  I made a 95mm set out of steel because the inboard wing spar web material is so thick.  I made a 115mm set out of aluminum because aluminum is easier to machine, and the rib material is relatively thin.
 
 I am willing to lend out these dies to anyone else who can use them and is willing to pay for shipping.  I am posting this message here for anyone who may be searching the archives at some point in the future.
 
 Happy Building!
