Doug, I always enjoy your stories! I suppose much like 3D printing of today, gluing was a technological advancement way back then. Montreal’s “Big O” Olympic stadium had major sections of the concrete pillars glued together... Back in the early ‘90s, parts were falling off, but that was more of the mafia-sourced concrete than the glue’s fault. Ferrari got the glue issue early on. Next up on the list, their brake master cylinders. Peter Sent from Mail for Windows From: Douglas Anderson Cool story about your dad gluing everything together Peter. In 1966 and on I worked as a machinist at Northrop (airframe) Corporation in Hawthorn CA to get me thru school. Northrop buildings and hangers were right next
to the 1940’s flying wing Hawthorne Airport runway. One mile long. The street parallel to it, 120th, was a GREAT, uh, auto engine testing and acceleration site. Um, a drag strip. I lived on 119th. The Beach Boys lived down the street from me on 119th. Never met them although in the late 50’s and early 60’s I did run against Brian Wilson in
cross country. My shift at Northrop was 4:10 to 12:10. Ten after the hour?? Guess there was a reason. Anyhow I’d get a job, execute it, and then, after work, I’d look around
to see where that part fit. Many of my gigs were for the F5A or T38 Talon, but there were also Boeing parts. As I poked about I found F5A stabilators .. . glued together on the leading
and trailing edge (both?) but it was glued. The whole mess was quite thin too. So were the wings . . . 2 or 3 inches, maybe 4, at the root. And on one day before starting my shift I saw a gaggle of guys carrying a huge circle made of wood – well, actually it looked like a 30 foot round theta. They
roll it up to a building and place it against certain parts of the building. Hmmmm – never to let weird stuff alone I ask . . . so, what are you guys doing? We’re measuring each building to see where we can build the parts for the new airplane for Boeing.
Ahhhh. Well I knew we made parts and cabins for 727’s for Boeing but these guys and their 30 foot theta are pulling my leg. Righhhht - I smiled, wished them good
luck and bid them adieu. Several years later . . . I found out Northrop may have been making fuselage parts for the 747. If they did – I never saw the line nor do I have any idea how
they transported the parts to Seattle. SuperGiganticHumongousPregnat Guppy? Yeah – Northrop – cool time had by all. Saaay, wasn’t it a faulty glue in the 458 Italia that allowed the inner engine bay cover to fall onto the exhaust system?
I seem to recall a recall for that. Was that little picadillo ever solved? Doug From: Ferrari <ferrari-bounces+dnt=dock.net [at] ferrarilist.com>
On Behalf Of Peter Rychel I’ve been fascinated with 3D printing since it came out. I think if I was a kid now, I’d have a blast. Despite having just the basic blocks, playing with Lego taught me so much about how to be creative, dexterous and imaginative. With 3D
printing, I would’ve been in another universe. I know you’re so well-versed in this, but, when I look at basic 3D printing, I see the limitless potential as a tool for prototyping and to a certain extent, limited production. I also see it’s natural use in being the master for casting
molds. What I have a problem understanding is how some people are making items directly out of metal and using it in physical applications. I think Jay Leno was 3D printing engine parts (I believe some critical). What filler material is being
used that makes this possible? Obviously the metal is in power form and the plastic carrier has certain properties to be used as such, but just how durable/strong could it be? Many years ago, my Dad had a reputation for gluing everything together. He had started his career working with chemicals in labs, before moving on to photography (even more use of chemicals!), but his fondness for binding anything and everything
together with glues/epoxies are legendary in our family. My memories include success and, lots of failure. I suppose in ways, it’s the failures that stick out in my mind and I can’t help but equate that with today’s “metal 3D printing”. Is it advanced to the
point where it can be substituted for actual metal castings? I chose welding as a career because I was always fascinated with how a person could take two pieces of metal and join them by melting them together. I’ve been doing this for almost 30 years and it still blows my mind – the process and my
ability to do so. Dad could do brazing, but was very limited to the size of the object. When I became a welder, and he had items that broke, It was my absolute honor to weld it back together for him. Peter P.S. I don’t want to hijack Rob’s thread, but I’ve made tools for Rob before and I welded them so this counts as on topic
😉 P.S.S. Rob, did you ever get the timing belts sorted out? Did you get 101s? Sent from
