Zack - 31 Jul 2005 17:22 GMT
I'm building a Testors 1/72 B-2 and have decided that I've never had a model
that fit worse than this one.  Nothing even fits close.  Having said that,
how can I fill and sand around the clear windscreen and the fuse without
goofing up the clear windows?  I need to fit the windows early so I can
smooth around the edges.  So, how do I smooth the gaps and still have nice
clear windows?  Do I just sand the windows and then somehow polish them back
smooth?  Any help would be great.

Thanks
Zack

Fit the windows, sand smooth, and then use progressively finer grades of
wet and dry (www.little-cars.com do a great set that goes up to 12000
grit) to achieve a clear finish.  Any window framing will have to be
reproduced using tape or paint.

You can also get very fine sanding sticks from a
spouse/girlfriend/partner (?) - they use them on their fingernails and
they go to about 6000 grit which is also pretty good.

(Not sure why they need smooth fingernails to do the washing up but
there you go - women, can't live with them, can't live with them.)

Good luck.

At that fine of grit, do I have to polish after using or will it leave the
windows clear?  Should I still cover with Future?  Will the Future fill in
some of the imperfections of the sanding?

Micro Mesh is the brand name of the product - I don't polish or use
Future/Klear, as the plastic looks pretty clear after using the
micro-mesh.  Many recommend the stuff but I can't get it to dry very
well for some reason.

I would superglue the window in place and fill in all gaps. It would help if
you dipped the canopy in future to prevent the CA from fogging you canopy.
Then block sand to blend it into the fuselage. Polish out the glass portions
then give the glass a swipe with a cotton swap dipped in future! let cure
for a few days and then mask with Tamiya tape and paint as normal

Yeah....what Scott said.

The only thing I could add....is to make very sure that the cockpit
interior is 150% sealed against *any* traces of sanding dust (or
sanding "sludge", when wet-sanding) getting inside.  Once such dust enters
the cockpit, it has a nasty tendency to be attracted to the inside face of
the clear plastic, and is next to impossible to get rid of.

Very important point this one...as I had to find out the hard way with
my Hunting Percival Pembroke...(lots of filling & sanding on this one)
I masked the outside with Tamiya masking tape, filled, sanded...but
when I removed the tape the mess was on the inside....a nice coat of
dried sanding dust... no f. way to get at it.
May be in addition to sealing the cockpit from the inside it could be
helpful to do all other sanding operations prior to the installation
of the windows so that there is less dust to threaten the inside.

I used Microscale Clear to make the side windows; that worked well.

Just an idea, possibly for a last ditch attempt: the windows on a B2
appear to be relatively small. Maybe you could simply ignore the windows
initially, then, when everything is smooth, drill and file away all clear
plastic that is window instead of window frame. Fill up the holes with a
membrane of clearfix, micro kristal clear, or any other instant window
material. I shouldn't need to say this, but if you choose this path test
on a similar sized hole in some scrap plastic to see if the material will
cover a hole this size..

Fit the windows and then cover them with masking tape to protect them.
Then go ahead and fill, sand to your heart's content being careful not
to sand through the masking tape.  Remeve and replace the tape from time
to time to check your progress.

Once you're close, you may want to switch to a thinner tape - like
Scotch tape - to get a smoother transition.  Just remember that if
you're using Scotch tape you don't want to leave it on the clear parts
much more than overnight - it's high tack tends to make it stick better
the longer you leave it on.  (I often use it to represent raised panels,
if I can get it to follow the contour of the area.)

In addition to the others comments;
Toothpaste makes a good inexpensive polish for clear parts, and
Don't apply a lot of pressure when sanding or polishing. After a while you
will get tiny little stress cracks in the clear parts.
Just use some patience and your windscreen will look great.

Make sure you use the "cream" type toothpaste. The "gel" type won't do
you a lot of good.

Ok Guys:

Here is where I stand now.  (other than on my feet..  hah)

Sorry, any way, when I installed to windscreen the clear windsheild needed
to be sanded down to be flat.  I had to do this so other places would not be
recessed.  I dipped to clear windscreen in Future to protect it from the
glue, and have used the lightest touch possible to sand/file the area.  I
raided my wife's bathroom and came up with some nail files that are rather
usefull, but the clear part will still have to be poished back to clear.  I
have been fairly lucky and only have a few specs of dust on the inside of
the screen.  As for making new clear areas these windows will be too large
for the liquid window ideas.  How do I now go about polishing these areas?
Do I use a motor tool like a Dremel?  What compounds?  Where do I get them?

Thanks for all the help.  This thing is starting to look like a B-2.  (
granted on that is stuck in a bodyshop)

Any one want to see some pics?

I tried to post some pics under B-2 construction, but its my first attempt
at posting pics. So if you all don't find them let me know and I'll try
again.

Obviously, you do.  That's quite a struggle you're waging with that kit.
I recommend that anyone interested look in on Zack's accomplishments so
far.

Believe it or not, this is the project I moved to when I got too frustrated
with My B-52 D to H conversion.  It's actually going better.

What I do is use baremetal foil as a super masking tape. I mask the
actual transparency area with that.  Then I add putty and sand.  After
painting, I remove the foil. You CAN sand it away so you need to be
careful when sanding the puttied area.  I sometimes use fine needle
files for smoothing around window areas rather than sandpaper.
