Duct tape mess

Jay Scheevel <scheevel@...>
 

Hi Guys,



I have just unearthed my long-stored tail cone sections and I had long ago
cut, fit, and joined "temporarily" with duct tape. I have just removed the
tape and the predictable stickum is left there. I am looking for a safe way
to remove the stickum without damaging the shell layups or the urethane foam
underneath. Any good ideas before I try something wicked like MEK?



Cheers,

Jay Scheevel - Tri-Q, still building

My description of EPS was wrong. You do need XPS. The EPS will work for my unique purpose. To find lots of XPS suppliers google "extruded polystyrene". Clark Foam, among others is there.

Here is a link to some information on "extruded polystyrene foam" as
characterized by the following web site.

This thread seems to be drifting around and I'm not quite sure who is
actually looking for foam. The type of foam we use in the wings, vertical
fin, and control surfaces is Dow Styrofoam brand buoyancy billets. Over
the
years I have purchased it from Aircraft Spruce, Wicks, Cope Plastics, and
once even Sears. It normally comes in blocks 96" long x 10" or 12" thick
and is either orange or blue. A quick check seems to reveal that Aircraft
Spruce no longer carries it. My last purchase was from Wicks and they had
to order it for me.

Expanded polystyrene is absolutely the wrong stuff and will probably lead
to
death. It is recognizable by the characteristic little white beads that
are
formed as you break it apart. Also, the 1" thick Styrofoam seen at lumber
yards is also the wrong stuff and should not be used.

Re: Local foam source

Based on David Gall's lurk, I googled "insulated foam warehouses". I got
http://univfoam.com/ as a source. I contacted them and was told that
they can not only supply what you need, but can also supply the foam pre
cut to shapes when they have CAD templates. Their minimum order is $250.

In my part of the world I have discovered that the foam can also be ordered as "pipe insulation billets". Exactly the same stuff. The oil field and refineries seem to use lots of it.

That looks reasonable. Maybe you are right and accepting a bulky trailer is the way to go.

No offense, but I think you're just plain wrong about this. The Q1 when it is cut to make it trailerable is less than 96 inches long. Check this out:

You do understand that the airframe is NOT towed facing forward right? It is towed sideways. Here's a website that shows a Q2 on a trailer:

Just for my own curiosity I did a VERY quick CAD of a Quickie with the stock cut fit inside a trailer within a 94 inch internal width and a 4 meter height.

I posted - european trailer.jpg - in the files section to show how it would fit. It does. It would require a pitch up of about 44 degrees from 3 point attitude. A trailer only about 2.5m tall would be required.

Re: CNC Hot Wire travel for Q1

Seeadler18 <marko.rocznik@...>
 

I know the Cri-Cri and I know the BD5. Both very attractive designs, I just belief that the high wing load isn't save. The accident statistics also is very different from the one the Q1 has. In addition I'm pretty good with fiber glass (I own the license for big repairs on fiber glass except spars) but I do not like metal airframes. And most important: I'm a big fan of Burt Rutan!

I belief that being an engineer I can do the math for load carrying structures. But I do not have expierience in overall aircraft design (and even several books didn't change this). So taking the Q1 aerodynamic and weights as it is and not changing it sounds like a good idea. So the weight panelty has to stay within an acceptable range.

As I said - it will take several weeks Solid Works time, designing, analysing, putting things into the bin, and starting over again. I'm not going to build any parts before the FE analysis doesn't look promising.

Thinking about the technology and tools is also important. Since the airframe otherwise should be exactly as the plans tell me, I beliefed that putting together a CNC hot wire cutter in the meanwhile is a good idea. You might be right an focusing onto the final goal might be more worth.

For now you answered tons of questions and I just need some time for modeling and FE simulations. I will upload results on my webpage and post the link, asking for your opinion. (www.Rocznik.de/Marko)

Thanks for now!

Hi Leon, Bruce, Jon & Mike,

Working in research, I'm used to hear "that will never work". And you might be right and the analysis of my Solid Works model will tell me, that the weight penalty is to high for the small Q1.

Whenever I fly my DG400, I have to put the wings on, hook up all controls (aileron, dive brakes, water ballast, fuel tanks, bug wipers) and I admit - it costs me at least 10 minutes of flying every weekend!

Here in California I could imagine to have the wings fixed attached to the fuselage, since there are these US typical small hangars, which you could even share with somebody. But my wife wishes that our kids go to school in Germany and so in a couple of years I will not be able to use a hangar. An enclosed Q1 monster trailer wouldn't get an road worthiness certificate in Germany since is is by far wider than what is allowed for a trailer. So the only chance really is to store it like a glider in an small enclosed trailer.

And you are right - the project might take 10 years to finish - exactly the time that my children do not see their farther sitting in front of a computer, but building something with the own hands - a skill which nowadays it totally undervalued.

And you are right - I might never fly it, but even if so - that's OK as long as the dream of finishing it one day makes my life better.

I even belief that the air frame isn't really the biggest challenge, since everything is well defined. Coming up with an engine solution which will satisfy the high German noise requirements will be even harder! The Onan is an absolute NO-NO and also the Rotax can't be flown everywhere. The same problem is addressed by by e-Go (http://web.me.com/tony.bishop/e-Go/welcome.html), because noise is an big issue over there in Europe.

So I try to life the dream of an state of the art Q1, which is featuring Rutan's genius design, using 21st century technology.

The original kits used foam blocks that were 10" x 14" x 52". So a table 60 inches long with an Z axis of 20" and an X axis of 12" would be sufficient....IMHO Keep in mind that the longer the table is the more capacity you will need on the other axis for "over-run" to cut the tapers.

But - I'd not bother for what you want to do. I have the CAD files, the software and a box of linear bearings, steppers, ball screws, and electronics to do exactly what you are thinking about. For a one of a kind I'd do it by hand.

Loft the templates in CAD, print them, past them to some template material and hot-wire by hand. It will be MUCH quicker and the finished product will be within fractions of a percent of the quality of the CNC cut ones - if you take your time and have a good hot-wire partner.

The original kits came with templates that were copies of hand lofted airfoils that were then cut out by builders of varying skills. The vast majority of these produced usable cores.

While we may have "better" methods available today sometimes the old ways work just as well.

If you like making CNC machines, like many of us that also build planes do, then have fun!

For now I would like to get your opinion about the spec for the X and Z travel needed.

Re: CNC Hot Wire travel for Q1

German trailer rools:
Maximum width 2.55 m (about 100 inch)
Maximum hight 4.00 m

No way to get a Q1 with removed tail into these dimensions. A glider like design will have a nice little trailer.

Sorry, only just started to see this thread.
My trailer means that I can remove the tail on my TriQ and have the fuselage at 90 degrees. Complies with UK transportation by trailer rules plus 3 inches and the cops wont know the regs methinks. I think you can transport higher widths with flashing yellow lights and "Wide Load" as a sign.

If this is what you want to do I say "go for it". I'm of the opinion that if we always listened to those that say "it will never work" we'd still be chasing our next meal with a sharp stick :-)

Rather than making the wings removable have you considered breaking the fuselage between the wings? You could then stack the 3 large pieces in a European legal trailer. Only the engine/canard section would weigh much.
