Glastar - 2020

We just riveted the flange to the firewall that is used to attached it to the fiberglass frame.  The rivets used are monel rivets.  These are extremely hard and are used to secure the two stainless pieces together. Bucking them tends to be a frustrating process at best to make it work.  Dennis Vanatta to the rescue.  Denis designed a tool he called “the ugly machine”.  In the pictures he shows Regie Roorda and Andy Johnson how to use it to hydraulically put up to 20,000 lbs of force needed to set these very hard rivets. The result are perfectly set and consistent monel rivets, thanks to Dennis Vanetta.  The Glastar is being built at Jerry Schiroo’s Shop, Tuesday evenings 6:00 pm – 9:00 pm; Thursdays 1:00 pm – 5:00 pm; Saturday’s 9:00 am – noon.  Ch. 25 members are invited to attend.  All members and friends are welcome.  Contact Jerry Schiroo: with any questions and location information.
