What type of aluminum?

You'll want to reinforce zero temper aluminum since it is very soft and any non-supported areas could sag over time. Soda pop cans are typically made from a AA 3004 or 3104, which is aluminum containing manganese and some magnesium. The 3XXX alloys are not heat treatable, and have excellent formability and corrosion resistance.

Here are your parts buddy, we wound up manufacturing them from .025" thick 6061-T6 because that is what is in stock at the moment. They are both light and rigid in this configuration and should work well for you should you decide to use them. I provided the shop floor with a drawing and posted bend data to the CNC brake press to make things simple, I also went ahead and had the guys run two of them 20" long because I figure you may be able to use them on another project down the line and it is literally only another minute to bend a second piece while setup. All I need is a PM with your address and I will get them shipped out to you next week and provide you with a tracking number.
Merry Christmas Robert,

Fantastic, and don't worry, they will get used. I need a set for my current build and have two more in the works, another S1-S and a Challenger II. Yes, I love Pitts!!

If your talking of the rolled aluminum flashing, so do I. But it is not sufficient for this application, these frame rail mounts are structural in that they hold the canopy on the roller slides.

Sensei, normally, I look at titles as just that, a title. I've found that many people that hold a title are hired by a company due to the piece of paper they hang on the wall that says they know something. Where I work, there are many people that are "managers" that have no background or knowledge in the industry and they were hired just due to that piece of paper saying they finished a few years in school, regardless of what the field they studied was. It's really bad when someone with no experience comes into a shop as a manager and starts throwing his title around to show his authority over those that know what they're doing and have decades on the job.
I'm surprised that some say not to use 6061-T6. Many of the parts used in the construction of full sized and scale hydroplanes are made of 6061 due to it's machining characteristics and strength over other types of aluminum.

Hydro Junkie,
Well you can rest assured, I did not get my title that way, I actually came up through the school of hard knocks and a million dollar education shoved up my ***** a nickels worth at a time over the last 4 decades.
You stated: I'm surprised that some say not to use 6061-T6. Many of the parts used in the construction of full sized and scale hydroplanes are made of 6061 due to its machining characteristics and strength over other types of aluminum.
Probably the main reasons for the use of 6061-T6 is the cost is by far much cheaper compared to 2024-T3 or 7075-T6, 6061-T6 possesses a little better corrosion resistance over 2024-T3 and 7075-T6, and finally 6061-T6 can be welded, the others cannot.
For the record, I never stated that 6061-T6 cannot be machined, I stated it just doesn't machine as well as the other materials I listed due to its softer and gummier nature. Finally your assumption of 6061-T6 being a stronger alloy over the other alloys I mentioned earlier in this thread is just that, an assumption only. The truth is 2024-T3 is notably stronger than 6061-T6 and 7075-T6 is way over the top in terms of strength compared to 6061-T6. These are the facts, they are not mine but still the facts.

These are two exceptional people and a good example of those "who know" helping and sharing. Thank you to both of you, I will put all of them to good use. I will also add you guys to the list on my poster of contributors of the build, that is if you don't mind.
Merry Christmas and God bless!

Hello Robert,
They are packaged up and ready for UPS pickup and ground delivery to your home, I will PM you the tracking number in hopefully just a few minutes or as soon as I get it from our shipping department. FYI the tracking number may not work until after the pickup scan this evening.
Talk to you later,
Bob

[h=3]Main Navigation[/h]
[h=1]About Us[/h]
M & M Precision was started in 1996 as a part time venture, by owners Mike & Marcia Burg. Mike has over 40 years experience as a Journeyman Tool & Die Maker/Manufacturing Engineer. In 2004, Mike decided to expand from a part time venture to full time. Midway through 2005, Mike purchased the company's first CNC machining center, a used 1988 Millport. Through the help of his friend, who had many years fixing and maintaining CNC equipment, they were able to get it up and running. It was at this time Mike brought on his son, Jeff, who is also a Journeyman Tool & Die Maker, as a consultant. Mike & Jeff went to IMTS, for the first time, in 2006 to purchase a new Fadal 4020. The business was doing well and they were able to keep both spindles constantly running. In 2008, Mike and Jeff once again attended IMTS, with a radical idea. They wanted to separate themselves from the pack and purchased a Johnford DMC-3100SH twin column machining center. The economical downturn of 2008-2009 was tough for a lot of shops, but M & M was able to stay extremely busy and have the best year for gross sales up to that point. M & M has continued to grow and purchase new equipment and their sales have grown exponentially.
Plans are completed for putting in a large horizontal boring mill with travels of 197" x 118". The machine is up and running now.
M & M's current success is due, in part, to their great work ethic, old school personalized customer service, and a great team of employees who always get the jobs done with customer satisfaction in mind.
For more information, send us a request on our Contact Us page, or call 716-434-6525

This reminds me of my Wife's last birthday party. While exiting the restaurant a huge Ford F-350 pulls up to the front door. This thing was raised, big wheels and tires, lots of graphics and loud. My sister looks at the driver and shouts " NICE TRUCK!, sorry about your p***s"

I love this... It really got under your skin that we were actually able to help a fellow modeler out in the real world using know aerospace processess and materials. I must be honest with you, I expected more than this from you and your NY buddy. Anyway what is that large what appears to be S/S structure from the color of the metal and welds? It doesn't look like it can fly. Oh well...

And help you two did. Both sets are fantastic and will make for an easier finish job on the canopy. I would post some pics but I am at home and don't have my camera. Next trip to the shop I will post on my thread for those interested in seeing them. Again, thank you to Sensei and Speedracerntrixie, very much appreciated.

I must be confused. Isn't vacuum simply removing atmospheric pressure? If it is then to the best of my knowledge the best one can accomplish is about 30" at sea level and it decreases the higher your altitude. Unless it's some sort of autoclave and then it works on pressure.

So, if I find myself in Fl. Then Imget a flight right? LOL glad you like the parts, it was fun coming up with an easy way to make them. In all I had about an hour into them. BTW, the resin system I used is Tap Plastics Marine grade with medium hardener. I actually like it better then West Systems. The cure time was only 2 hours at 125 degrees and it makes for a fairly stiff part.
