HI
Tonight I wanted to clean up my garage for the next steps.
I also need to prep the car for the epoxy step
the car should not be damaged
so I have to remove the hardtop
to then carefully cover everything with foil
was a bit nervous
but
it was so easy
I got a scale to measure the weight
exactly 4 kg
and see what I could do with it

i will make the first 2. layers on the outside
with the hardtop on the car,
for the 3. layer i will take the hardtop off the car

if I have a driver's license in winter, I could take the car for a drive arond the corner with the hardtop on it
i hope i will get the epoxy on tuesday or wendsday

[Franz Tenbrock]

Hello
Waiting for the epoxy, some small steps forward
Here are a few more steps
The weight is now 4kg
easily removable

The first step was to cut the carbon fiber to size
I used 5mm wide adhesive tape for this
then cut in the middle so that the carbon stays as it is and does not fray
as the carbon is 150 cm wide, I first cut off 125 cm, which is the width I need
so I can see how it works on the roof
as you can see the roof is a bit curved, good for stability
first I will paint it with epoxy, when it gets sticky you can fix the first carbon layer well, only then soak it with epoxy, that's how I saw it in videos

i hope you have fun to see the pictures,

[Franz Tenbrock]

Hi
got just in the moment the information that the epoxy will come tomorrow
so i can start on friday ???
nervous

Daumen drücken!

this we would say here

[Steve Simmons]

Good luck!

[Franz Tenbrock]

Last night when i went to bed
about 110220 counts
So i thought i coud get the
111111 Post
here in Germany we say "Schnapszahl"
but here are so much people reading the thread ..
seems to be interesting all stuff Here
So i can start today with the epoxy

first i have to heat up my garage

Sorry for the mistakes

[Franz Tenbrock]

outside its done

i started in the morning with heating up my garage to 15 degrees

first step one layer with carbon from the front to the edge in the back
both sides the carbon goes around to the plywood
i will cut it away when it is hard and i have to do the inside

before i layed the carbon 200 g/m2 on the roof i painted 30 cm in the front
then i layed the carbon in the bakc of the roof and took it to the edge in the front
step by step i controlled both sides then i painted the back of the roof with epoxy and put it on it

the garage had 17 degrees now

after 2 hours i put on the second layer as i have done the first

then i made both sides, first some epoxy to the xps the the carbon on it after this i fixed it with a special rolling tool
in the back the window was a little bit tricky
as you see i hold it in position with a part xps
now i have to wait until it is hard, i think it will take 2 days
all the time i will heat the garage

had a good run i think...

when it is hard outside i will grind inside in the back where the corner is
we will see how it works

the xps is only 3 kg so i will make a sandwich from it
i can sit in the car this i have tested some dasy ago

I worked absolutely correctly with the weight of the epoxy, stirred it for a very long time. so it should also become hard
we will see

[Franz Tenbrock]

at the moment I'm thinking about using something like this here
Thixotropic powder with epoxy
seen a video there he used Epoxy Thiotropic and Microballons
i have the Thio but not the microballons
have to order them or i use ready epoxy filler
and then fill the roof surface with it
so I could smooth out the fibers,
I have to grind later
no question
but I don't want to damage the fibers in the process

what do you think about ?

at the moment I have an infrared panel near the car to cure the resin faster
and it works great ;-) as i saw in the moment

[jddevel]

Hi Franz, Have you a yacht or power boat builder you could speak to. They may be able to advise you on the "gelcoat" they use to cover their glass fibre boats with.

[Franz Tenbrock]

here is the weight in the moment
fantastic
only 7,3 kg
and i can put it on the car without the help of someone else
for stability i don t need the inside carbon, but i wil do it because it prevents the inside xps
only one layer and i will paint it clear so you can see what it is
i grind the xps inside the hardtop outside in the garden
with a mask on my face
it was a job of three hours
the corners left and right was difficult
have to make some changes next days?? with a different tool

all following work i can do without the car
that s the best for the moment

i have enough epoxy to make the inside layer and the cream just have to wait for the microballons
also i found some parts i need for the next steps
always you have to know thee right worde to search the web
Scheuerleiste, Prallleiste
and so on

some synthetic leather outside , i will find a way -

i was really afraid how hard the carbon epoxy mix will be
now i know it is so hard !!

[Franz Tenbrock]

in the afternoon i grind a little bit+inside and outside
500 gr epoxy cream will be enough i hope for the finish


after dinner I went into my garage for a few minutes
cut the carbon for tomorrow
inside I will make a layer
and I hope I can make it so good that I can paint it clear
so you can see what it is

now boaring TV
so i looked around on the internet

found this
https://www.plprofile.de/scheuerleisten ... farbe-grau

and the chrome ends

with this it is possible to make the bottom edge like my template

I removed the fastening of the fabric roof in the rear area, it was screwed on,
if I now replace the screws with snap fasteners
and then put some artificial leather with snap fasteners under the rubbing strip of the hardtop, I can quickly remove the fabric roof and additionally secure the hardtop

a step forward in my head nearly ready

[Franz Tenbrock]

this morning I did the inside of the hardtop, one coat will be enough
more time today to take some pictures ;-)

I always made 200 gr and 120 gr together
mixed carefully
you can also see all my tools I worked with

the roller i used was not perfect
"varnish roller fine foam 10 cm"
the roller was damaged at the end after 10 minutes
and small pieces were on the carbon
next time I do something like this I will use a different roller
like this one
"Paint roller velour paint roller"

First, I filled the holes under the right-hand side where you can see the collets
after I applied the epoxy I rolled with the special roller several times over the inside

[Franz Tenbrock]

here are some pictures from the inside
first i rolled some epoxy on the xps, then i folded back the carbon
Step by step until completion
in the evening i will paint last epoxy on the inside

also i made a stainless steel 3D part for the laser cutter with freecad
happy that i have learned it over the last years
so it is easy to get such a part
it will be the surroung for the window in the back

[Franz Tenbrock]

last step for weekend ;-)
one coating with 120 gr Epoxy
with a short hair roller
much better then the other one

really happy with the result
3 days work and a lot of fun seeing my dream come true

now i know how to make the back window
for the sidewindows i have an idea how to make it
some welding with steel
will make it like my spartan sidewindows with a sliding screen
only one little part i have to think about
this was the 14. day i worked on the hardtop
happy with the result for the moment

[Franz Tenbrock]

Last night i had a dream how can i make the Side-Windows
first i wanted to slide back the rear sidewwindows in the back of the hardtop
but there i have the b pillar fixing points
so ist will not work like this

now i have a different solution
for the front sidewindows i will take aluminium U Profil

i will put in this here:

https://www.ebay.de/itm/154730013276?_t ... 1506.m1851

now the Glas can slide
for the backwindows i will make a cut so the windows can slide through backwards
I will take a knob to push the window back

This knob ist also the Stop Point

I don t understand the picture from the template
how is the Front Windows fixed, look to the A pillar, there is something missing ???

In my solution i can slide Back the front windows to reach the mirror or push the rear windows to the front to Open the door

cut it from paper to test it, was the fasted way

WE will see

[Franz Tenbrock]

Hello everyone
4 days ago we had 111xxx counts here now 144xxx
seems to be really interesting
Unfortunately no pictures today
no time for garage today
only time to take the weight of the hardtop with the carbon in it
8,2 kg and it is so stable

last days of my real work in office before i have christmas holidays

the problem for the next days
christmas new year, a lot of stores closed
difficult to get parts for the next steps
a lot of time to think about how i can design the side windows
the fixing of the hardtop at the b pillar
and so on

so you have to read the books you get on christmas
or you can think how you can make your own hardtop

The instructions are now available

[Franz Tenbrock]

I came back from work today and the dishwasher was damaged.
my wife was a little bit angry
a damaged dishwasher some days before christmas
I hate this kind of work.
but it's so expensive to call a specialist
so I took a screwdriver and removed some parts to have a look under the dishwasher
there's some water dripping down
at first I couldn't see the problem as I had little room to see anything.
then I found this pipe in the picture, the dishwasher is only 5 years old ...
same problem with the rubbers we can buy for our cars ;-)
ordered a new one , will come on Friday

I put the hardtop back on the car
it's easy to do yourself
I took off my side windows and put them on the car
you can see the difference, a bit more space for my head
the red line shows the line for my sliding windows,
I will try the back line to make the back window a little smaller
I have some aluminum U-profiles 10-20-10 and a plastic profile for the windows
months ago I had bought a special aluminum solder at a trade show, maybe it will work with it

so again no experience but a plan how it could work

[Franz Tenbrock]

Hi just tried the special Alu soldering
it works easy but would it be strong enough
in my hands it is ok
but now i have a template with the right angles

it is 28cm high 1,5 cm less will be better
at the a pillar it could hit the car and damage the paint,

i have a welding maschin for aluminium but never tested and the parts are really thin
have aske some friends.
but with a template it is much easyer to ask them
also i can see where i have to make some changes

got the microballons today for the epoxy cream

if i don t find anyone who can weld it i thought just in the moment i could take this here
https://shop.hp-textiles.com/shop/de/17 ... c-050.html
put it around the window to fix it
should be stable enough
i would paint all in black as i would do it with the alu so no difference
will ask the shop tomorrow what they think about


started with my projekt 16 days ago, so a good run until today
more then 100000 hits to my blog here
some traffic for this side ;-)

[Franz Tenbrock]

Hello
last day of work today
a few days vacation

drove around to find someone who can weld aluminum
all stores are closed

so i will solder it and in the corners i will make a gusset plate inside and outside under the gusset plate i will make some epoxy
the red point are 3mm screws
that will probably be strong enough

the dishwasher runs again ;-= horrible work

maybe I'll do the brown leatherette on the outside of the roof, like on the classic pre-war cars
or better black, or only paint it ?????

[Franz Tenbrock]

first side window on a good way
made it a little bit smaller not 28 cm high now 26 cm high
now it wood not damage the car in the front
also i can solder it now perfectly
but
i have made some gusset outside,
should i make some gussets inside too??

also i have an idea how so fix all togehter so i can put it to the door
have too buy some aluminium first for the next steps

[Franz Tenbrock]

in the pictures it was paper before

now one side is made of aluminum
20x5mm 40x3mm and 10mm with a thread

sp I found a really robust construction and also really light
at the moment everything is assembled with screws
I'm going to epoxy it underneath so it's indestructible
I hope I can fit everything in the back of the car.
doesn't matter
I'm very happy with the result
all the other work is just a bit of work now
the way I have done it will work
