Re: fitting the cowl

Joseph M Snow <1flashq@...>
 

Jon,
 
I do not have any photos of my process to acquire "straight" lines at the cowl/fusalage junction.  I created a straight edge on the cowl; then, wrapped the cowl edges with duct tape as a release.  The cowl was installed onto the airframe.  A matching straight edge was created by packing flox into the gap between the cowl and fuselage.  When cured, the resulting edge is the width of the duct tape and matches the cowl edge.  Here is a link to my cowl photos enclosing the corvair engine:  http://www.corvairq.info/Cowl.htm

Actually, when you really think about, skinning the cores does nothing.
JMHO.

If skinning were to actually help, the inside of the foam would have to move
- to settle into a new position. I just don't think that really happens.

Have we confused you enough, Dan?

Thanks Charlie,
I do understand all of that. My question is whether the template
"level lines" need to be placed at the same distance verically
above/below a predefined "water line"

Let's say the table you are about to cut your foam cores on is level in
all directions.

You place one template on the end of the foam block with the "Level
Line" say 5 inches off the table.

On the other end of the foam block, do you need to put the other
template's "Level Line" 5 inches off of the table?

Or is there some other reference to align the templates vertically on
the foam blocks?

This is hard to describe without a picture, maybe I'll skectch
something quickly if my question still doesn't make sense. Please let

LS1 Foam Layout. . .

Rick Hole
 

I would not agree. If the table is not level the cut ends will not be
square with the bottom edge and you will have to do some extra work to line
up the cores on the jigging fixture. Take a couple minutes and level the
table.

As far as the note that you can line up the eventual trim lines at the edge of the block, you have the option to do that, but you must do the same at both ends of the foam block. I'd use the whole template unless there is no extra foam for the whole thing.

Thanks Rick,
The problem is that the LS1 plans aren't very precise. They seem to be
an addendum to an addendum, with various references to the Q2 plans.
The Q2 plans say that you line the T.E. of the templates to the Squared
off foam block, but it also says that you can leave the trim lines
dangling off the end of the foam if you want. So that leaves some
wiggle room fore and aft.

Then it doesn't really say how to align the templates vertically from
end to end. Except an obscure reference to "Water Lines" in the
Education Chapter (3). There are no offsets or exceptions listed on the
templates, and no vertical dimensions given. Just a rough sketch of the
GU canard templates tacked to the ends of the foam, with no precise
locations given.

If the templates cut the foam perpendicular to the wing, and then the
wing is swept back, and anhedral is added, doesn't this change the shape
of the airfoil to the relative wind (Along BL0).

I know that the templates seem to have worked fine for many of you, and
they resulted in several beautifully flying airplanes. I'm just
wondering how people actually cut out their canards, and get my head

For the wings, the cores are cut in such a way that the joints are
perpendicular to the wing itself, not parallel to the axes of the
plane. At the center joint, where left and right wings join, this cut
is not perpendicular to the flat bottom edge of the foam. The foam
block has is cut to make the junction angle come out right, or very
close to right. The only joint which is does not "fit like a glove"

The level lines on the hot wire templates turn out to be the same

My wing and canard fits were essentially perfect in alignment.

Yes, you are correct that the shape of the wing is altered doing this, but the core templates are shaped to compensate.

Dan,



The height of the template level lines from the table should be the same.



I recommend making two templates for the BL-100 elevator template. One
oversized and the other to plans spec. Hotwire, using the oversized
template and then use the plans spec template for sanding the core to the
proper size. Give me a call if you need further information.

In complete deference to my friend John, whom I know is an expert in
urethane and knows more about the subject than the bare inkling that I will
ever have, I have been using urethane tubing with great success for most of
the life of my Q-200. Maybe it's the formulation that makes the difference.

I started out with Tygon, which was better then the original vinyl tubing
that QAC supplied. The Tygon was okay, then I stumbled across this stuff
called *Tygothane, *which is much better.

I get it here:

http://www.mcmaster.com/#tygothane-c-544-a-i.b.-tubing-and-tygothane-hose/=d22kke
I
think Wicks and Spruce carries it, also.

I like it because is has a smaller OD than the rubber, is easy to work
with,
and I can see the fuel inside. This stuff is really tough and abrasive
resistant and holds up to 100LL for a long time. I seem to change it out
every 5-7 years for no other reason than to be on the safe side.

Just my experience.

As I recall (it’s been 25+ years!), yes, you put the

blocks together without a big gap to fill.

I agree with Charlie’s comment about perfect cores, but don’t
overdo it. A lot of us built wings long before digital levels and
laser sighting devices. We measured with a ruler and checked level
with a bubble in a tube. When you jig everything together, you’ll

I appreciate your input.

Hi Dan,

When doing the hot wires, it is important to lay up the templates on
the foam precisely as shown in the plans. That way they will fit
together with a very minimum of effort.

For the wings, the cores are cut in such a way that the joints are
perpendicular to the wing itself, not parallel to the axes of the
plane. At the center joint, where left and right wings join, this cut
is not perpendicular to the flat bottom edge of the foam. The foam
block has is cut to make the junction angle come out right, or very
close to right. The only joint which is does not "fit like a glove"
may be that central joint. You will place a rib there anyway.

The level lines on the hot wire templates turn out to be the same
level on both ends of the foam block EXCEPT when noted specifically on
the plans and an offset distance will be given.

My wing and canard fits were essentially perfect in alignment.

Re: LS1 Foam Layout. . .

Thanks Charlie,
I do understand all of that. My question is whether the template "level lines" need to be placed at the same distance verically above/below a predefined "water line"

Let's say the table you are about to cut your foam cores on is level in all directions.

You place one template on the end of the foam block with the "Level Line" say 5 inches off the table.

On the other end of the foam block, do you need to put the other template's "Level Line" 5 inches off of the table?

Or is there some other reference to align the templates vertically on the foam blocks?

This is hard to describe without a picture, maybe I'll skectch something quickly if my question still doesn't make sense. Please let me know. I appreciate all of your input.

Thanks guys,
-Dan

"Level Lines" - to me this means that you level a template on one
end
of the foam block. (L.E. to T.E.)

"Water Lines" - to me this means that two separate templates are at
the
same height on opposite ends of the foam block.

I was just wondering if the "Level Lines" indicated on the
templates,
were also "Water Lines." (Or if it matters.)

Does that make sense? Please let me know. Again, I'm guessing that
you had to sand and futz with the cores to get them to all fit

Water lines/level lines, I believe we are talking about the same thing.

Hey Sam,
I noticed they have braided/reinforced Tygothane. Would that work any better than clear (except for sight gauge)?

In complete deference to my friend John, whom I know is an expert in
urethane and knows more about the subject than the bare inkling that I will
ever have, I have been using urethane tubing with great success for most of
the life of my Q-200. Maybe it's the formulation that makes the difference.

I started out with Tygon, which was better then the original vinyl tubing
that QAC supplied. The Tygon was okay, then I stumbled across this stuff
called *Tygothane, *which is much better.

I get it here:
http://www.mcmaster.com/#tygothane-c-544-a-i.b.-tubing-and-tygothane-hose/=d22kke
I
think Wicks and Spruce carries it, also.

I like it because is has a smaller OD than the rubber, is easy to work with,
and I can see the fuel inside. This stuff is really tough and abrasive
resistant and holds up to 100LL for a long time. I seem to change it out
every 5-7 years for no other reason than to be on the safe side.

Just my experience.

Sam

You've got to love QAC. . .

I have been working with a set of LS1 templates and trying to figure
out how they get lined up on the ends of the foam blocks.

The LS1 instructions say to use the same block sizes called out in the
Q2 plans, but the angles generated don't really match the sweep of the
LS1 canard. So how do you know where to place the templates
horizontally on the blocks.

Also, on page 3-6 of the Q2 plans it calls the "level Lines" drawn on
the templates "Water Lines" does this mean that the "Level Lines" on the
templates are placed at the same level vertically on the ends of the
foam blocks as well as being "level"? Or is this just an artifact from
the VariEZ plans that got copied and pasted into the Q2 plans?

I'm guessing that you Q-200 (and Q1 LS1) guys had a lot of futzing
around to do in order to get your cores to fit on the spars. Let me
know how you did it! I appreciate your experience.

Re: fitting the cowl

Bruce Crain
 

I built a fake firewall out of 3/4" plywood and then glued 1/2 tongue depressor to the outside of the fake firewall. I then fit the cowl to the inside of the tongue depressors. Then I duct taped the inside of the cowl and the fake firewall for a mold release so then I could lay up a flange inside. When it set up the flange was ready to move and coleco to the firewall and pop rivet.Bruce

Hi Jon,

I just made the edge of the cowl straight. With cowl screwed in place,
Duct taped the cowl edge for paint clearance and release then filled the gap
with filler. Guaranteed perfect gap.

Re: Jim Patillo fuel system

Clive Clapham
 

Hi

G-BXOY has the top mounted flush filler, works great. Jims idea good too. Mine has a stand pipe directly below the filler cap with hole cut at top to work as standard standpipe (overflow) all within the header. Only thing I would change be to make the stand pipe from top to entery into main lager diameter or split to allow air to escape quicker to speed up filling. NB the fuel system is ram air presurised so must be leak free. There is an advantage of top mounted filler if the cap is left of it's you know on climb out. I sure would love to see the picks of Jims( Sam or Jim any chance of posting then or sennding off line?) If any one asks I can post pic of header tank before glassinig in.

It has been a few years since I saw your plane. I was looking at the
