hey YouTube today I want to talk to you
about the LX 50 deforking and
modernization restoration project I've
decided to take on in the last video I
went ahead and deforked my telescope and
said that I was going to put some
dovetails on here in preparing to do the
dovetails I had to remove a set of
screws from the telescope here and here
and some of these screws were so rough
that they had siezed to the tube and I
had to drill them out to avoid getting
filings into the telescope that would
scratch up my optics I had remove the
optics so I went ahead and did that
pulled the screws out with the drill and a
tap and decided since I'm this far let's
go ahead and repaint and flock the
inside so I set out to do the paint job
I stripped all the paint off I primed it
with primer gray hit it with a flat
black because that I'm supposed to use
for this color shifting blue that we
decided to go with and it turned out
looking like shit as you can tell it's
kind of scuffed up it's a little hazy
there's a slight color shift to it and
the biggest annoyance of it all are
these black lines these black lines are
where none of the color shifting paint
stuck to the black primer and the reason
why it wasn't going to stick was even
though I tried to spray at the coldest
part of the day it was still 85 degrees
and the paint dried between the can and
the tube and I had to spray from just a
few inches away to get anything to stick
and that didn't give me a broad coat
uh a broad spray and it was incredibly narrow
so I ended up with these uneven spray
lines and I did my best to minimize them
but as you can see they're still there
and it just doesn't look right so what
I'm going to do is admit defeat I
don't know what I'm doing and I'm going
to take this any get it done
professionally and I'm hoping it's going
to turn out really cool what I did do
however and I
as well is I got a lot of video of how I
went from the original Meade blue to this
point and so what I want to do is show
those of you who are thinking about
taking our project like this but haven't
done it before what it took to get to
this point and I'm sure 90% of you 95%
of you out there have better paint skills
than I do I'm terrible at it
if you can do better paint jobs than I
can then I'm sure that you'll be able to
do a telescope that just looks beautiful
I suck my paint job sucks my telescope
looks like crap so why don't I show you
how I went from the Meade original blue
down to the bare metal and then built it
back up with the primer the black base
coat and in the color shifting paint and
what it took me to get to this stage
first off I needed to remove the paint
from the telescope tube to do this
I used a pretty strong paint remover
what I didn't realize when I was using
this at first is that in direct sunlight
on a black telescope or dark blue
telescope like my Meade is the spirits
inside of the paint stripper actually
boil away which you can see going on
right here now I did my best to kind of
spread it around so it could work at the
time I didn't realize I was kind of
defeating myself the more I spread it
around the faster that the volatile
chemicals inside of the paint thinner
would evaporate and the less time it was
actually effectively able to work and as
I began to try and scour it down through
the paint it just peeled off kind of
like a rubber cement or rubber
would and none of the paint ever
actually came off so after I got wise to
what was happening to the Sun I moved
into my garage and allowed the telescope
to kind of cool down before I tried
again this time I waited and saw that
the paint never actually boiled away so
I was able to spread it around over a
larger area and get it to react with the
paint a little bit unfortunately it was
not very reactive to this kind of paint
and it took an awful lot of scrubbing
just to get a little bit to flake off
but eventually I was able to get down to
some bare metal all in all it's taken me
about an hour just to get to this point
but I was about to have a little bit of
a breakthrough it turns out that this
paint really wasn't paint at all this
telescope had been powder coated and my
paint stripper did soften it up enough
to where I could get under and peel it
off and it peeled away almost like a
latex balloon or heat shrink wrap that
was shrank over the telescope tube so I
set about running paint thinner all over
the telescope tube letting it sit for
about 10 minutes and then peel away what
I could and this went on for about three
hours once I had to paint removed
I needed to fill the original screw
holes leftover from the deforking
process I used automotive body filler to
do this and an index card just to kinda
scrape it smooth with the surface once
filled I then went ahead and grabbed
some 100 grit sandpaper and attempted to
sand down all the remaining specks of
paint that the paint remover could not
get off
there were about a dozen or so spots all
over the tube and some of them were a
bitch to stand down I ended up actually
having to stand them flush with the
metal rather than just sand them off which
is what I was kind of hoping to do the
majority of the spots that I would had
to work on were around the rim now I'm
doing some priming on the optical tube
primer was needed for the paint that I
was going to put on as it was not a
primer and first coat all in one so I
opted for a sandable gray primer that I
could spray all over the tube to kind of
fill in some of the scratches that were
left over for my sanding of the paint
flecks also I was hoping it could kind
of fill in any of the unevenness from
the body filler I put in to the two
screw hole next I needed a better way to
paint putting it on a lazy susan just
wasn't working
I decided I could create a horizontal
roller by using a couple of wheels
screwed into two-by-fours like this I
picked these up at the Home Depot they
were only about 2 bucks each
I used leftover decking screws from when
I built the observatory deck to secure
these to a few spare two-by-fours
leftover also from other construction
projects we've had around the house with
the roller assembly done I was able to
mount the telescope tube to the rollers
and it worked out pretty well once I
actually got the wheels onto the black
metal part and not the piece that I was
trying to paint I could just roll it
around like this and I was able to then
paint left to right instead up and
down after doing a second priming I went
ahead
sanded it down to get rid of any orange
peel in the primer this is it after I
was done sanding for some reason the
video did not record when I was trying
to do the sanding so you can see what it
took it's glossy because it's still wet
from the wet sanding after I had
everything wet sanded and dried I went
ahead and removed the old plastic
masking that I had taped on it was
beginning to peel away from all the
moisture that was in there
and it was becoming a problem and I was
afraid that's a black paint and the
color shift paint would eventually get
into the places I didn't want it to so I
swapped out the old masking for some new
masking after the old masking was
removed I put on a pair of latex gloves
and wash them off to make sure there
wasn't any oil on them and then I went
ahead and used a few drops of dish soap
and warm soapy water to spray down the
optical tube and get any remaining dust
and finger oils left over from the
previous sanding I didn't want any of
this stuff to contaminate the black
paint job that I was about to put on
once I wiped it down with a towel to
kind of dry off any of the soapy water I
then hit it with just regular hose tap
water to get any remaining soapy residue
off the tube again I didn't want to need
that soapy residue to interfere with the
next color of black just to make sure it
dried fast and not to allow any moisture
to soak into the primer I went ahead and
towled it off with a few shop towels just
to make sure that the moisture would
stay on there then I moved it out to an
area where I can get a little bit better
visibility my garage was a little dark
and opted for the deck of my observatory
to re mask the optical tube now it was
about 9:30 or 10 o'clock in the morning
and it was already hot you can see sweat
dripping down my arm from in type to
those latex gloves there's also a bit
windy although on a hot Texas summer day
the wind is more like a hair dryer it
doesn't really do anything to make it
more comfortable it's a major hindrance
and it kept blowing this new masking
paper I was trying out everywhere and it
was a real bitch to get taped to the
optical tube but eventually I was able
to get a grip with the new tape and
secure it to the optical tube and tape
around this frog tape I have it
actually does not stick very well to the
Scotch blue painters tape nor does it
want to tear very easily if you're doing
this with latex gloves like I am doing
and you're already using some other form
of painters tape stick with whatever
painters tape you've got don't try this
frog tape it doesn't like it so what the
back of the optical tube assembly taped
up it's time to tape the front of the
tube and this time I got a little wise
and decided to just roll the tube along
the deck and allow the wind to maybe
push the paper into the telescope
instead of trying to blow it off of the
telescope this seemed to work a little
bit better
it took me about 20 minutes to tape the
top of the telescope tube this part only
took me about five minutes to do with
the masking all taped off I went ahead
and got the new black base coat applied
I was using a color shift paint from
rust-oleum and the color shift paint from
rust-oleum requires that I use a black
base coat I opted to go with a
semi-gloss based codes hoping that the
semi-gloss would allow for a better
color shift the rust-oleum did say that
I could just use black primer which is
it really gloss at all but I figured if
it's going to shine through to the black
and then be reflected off of that
a semi-gloss would give a more dramatic
effect I applied probably two or three
coats of the black paint it's kind of
hard to tell exactly how many coats I
put on because I would rotate the
telescope around sometimes two or three
times during a single coat and I was
going so light I don't know if it
actually counted as the single coat or
maybe two coats in one application
however for this last application I was
going for a little bit more of the gloss
coat and so I did spray it on a little
thicker and I took my time applying it
making it a little more wet and I
sprayed it on and I do think that this
really did help give it a good black
color with this final coat of black
paint added I then allowed it to dry
overnight and then I quickly sanded it
down just to remove any of the dry
overspray that had cured to the tube
biggest problem I had when applying the
color shift paint with how fast it dried
I was running into a few compounding
issues one was the paint would dry so
fast it wouldn't actually even adhere to
the telescope it would dry in midair the
second problem was that dry overspray
would land back on the tube as I was
spraying and get caught in anything that
was still wet the result was a milky
appearance of anything that did stick
and dried to the tube and I do believe
that this was a contributing factor
among my own stupidity and mistakes that
led to the black stripes being all over
the telescope also the white milky
looking appearance was the result of
tiny air bubbles trapped in the paint
and it dried I did my best to stand them
out and clean the tube up the best I
could
the reason the telescope looks so shiny
and actually has that purple color shift
here is because I had already been
sanding it for about three hours
it started at 320 grit sandpaper and
sanded for about an hour or two and then
eventually worked my way to 400 and
ultimately 600 grit sandpaper trying to
smooth this out eventually I had had
enough
and decided to call this telescope
project a lost cause with the help of a
local powder coater I'm going to be able
to get the color shift that I want by
using professional help I hope you have
