DAF torpedo front truck and front steer truck

[PetervR]

Hi
I've just got me a new project.
this time it has a deadline. normaly it takes years for me to finish a truck.
Now I'm going to finish 2 trucks befor october.
one tractor trailer, and a 4x4 tipper. both are from the 60s.
the cab's are going to be build from cartboard with PU-resin, I like the way that works for me.
The picture's made by charles burki, used in the official daf advertising are going to be my inspiration.
I'll add those pictures later.

the build is going to be posted on internet. but thats something I need te learn to make.

The cardboard process is not often seen for a master. I have seen it on other euro forums. Nice vid of the early stages. I am big fan of your bus build.

[PetervR]

Thanks for beeing a fan of the bus. It's sadly not finished yet.
I'm trying to post a few pictures but i'm having a hard Time with it.

This cab I had laying around. From an earier project that had ended before IT realy started. The reason was I couldend find the right parts. Now I think I found those.

Interesting looking trucks! Will be fun to follow :)

[PetervR]

Hi
just had some more work done on the torpedocab.
I closed the roof. and made it into 3 layers
http://www.mtc-techteam.nl/DD16961.JPG

also made the seats.

with the batterybox. als some room for electronics

and I have done some work on the outside.

I have to keep going on the truck. I Think I want a "Time correct" trailer build and rolling for the same event. luckely those trailers were simpel.
and it's going to look like the one in the picture. only the "long" version. thats looks a bit nicer in the layout of the sideboards.
I'll show the drawings next time

grtz PetervR

[PetervR]

it seems I've deleted the "short" trailer already.

this is the longe version. the difference for the sale model's was less than an inch. but the shorter one had 4 side boards on the site the longer one has 5 side boards.

That looks like an interesting way of building model trucks!

So if I understand it correctly, you are saturating the cardboard with resin and then sand it smooth?

As for the trailer, I know it is still beginning stages. Are you going to re-inforce with metal beams or is it going to be all wood?

[PetervR]

Hi.
yes the cardboard is saturated with resin. actually PU-lacker. it works just fine om the rounder cab models. and don't forget to saturate from the outside and the inside. or it will be curvey.

the strength is better dan a cab build up from sheets of plastic. lighter that resin casts. and it's sheap. (the calculated butget for this model tracktor and trailer. ready to roll. including radio and battery. under €300,-)

After sanding and putty. it will be spraypainted with car paint. is chould look just fine.

the trailer will I'm not going to use is as a skateboard. the load that will be on it will not be more than a few kilo. so for the loads it will not be nessary to be re-inforced.
from experianse I will re-inforce the pivet-point in the suspension. and the kingpin will be in the center of an aluminium plate. large enough for the fith-wheel.
the side's will have a brass strip, there just for some soldering to be able to have the sideboard's on.

[Rakthi]

Thanks for the info on the resin etc. Peter! Looking forward to further updates of this very interesting build!

Groeten nog!

[Finster]

Peter,

This will be a very unique truck and you are doing an awesome job making it. I am also interested in this technique of building cabs with cardboard. You've answered a few of my questions already with your posts but I have a lot more. So here goes:

Based on the photos are you using wood glue to initially glue the cardboard together?

PU-lacker is that the standard polyurethane that is used to cover wood items and you are brushing it on? How many coatings?

You said the roof is 3 layers, do you try to make the cab a certain number of layers or thickness?

Do you wet the cardboard at all to aid in bending/shaping?

What putty or filler do you use?

Thanks in advance. Sorry for so many questions...

[PetervR]

Hi.
I'll try to anser al those quesions. The first idea to build like this was an accident. I was casting a cab with resin in a silicone mold. And some of it dropped onto some peaces of cardboard. After a few minutes it was set and it was much stronger than the drops of resin that dropped next to the cardboard. So the idea was born. I first atempted to use the 2 component resin. At the " daf 33 small van" post here I used the 2 component resin. The idea worked. But it sets to fast. Also that cardboard I used there was bought. 1mm thick. And not that absorbent. Then my wife wanded me to take the trash out. And I saved some of the stuff I use now from the trash. It's 0,5mm thick. And more absorbent that the cardboard I used first.

Woodglue. Yes, why, no special reason. I even use it as treadlock.for the nuts and bolts.

The specs of the PU lacker I have to look it up. It's a PU that reacts to the air to set. And if i'm right it's also used for yachtdeks.

I apply it with a qtip. And as must as it can take. Up to the point it stays on top. A second coat will stay on top.
The inside is done in a later time. But must not be forgotten.

The 3 layers are for stability during handeling. 1,5mm togetter
Where I need to sand the shape more layers are put on.

I don't wet the cardboard for bending it. I use my nails to bend it into shape. If the fibers of the cardboard get loose. The soke up the lacker even better. So thats not a bad thing.

After the lacker I first use "plastic primer" than primer filler. Like the one I used on my car. Than its time for the car putty. I use a one component. From a dutch brand. When thats set and sanded. I use sprayputty from the same brand. Last sanding with grand 600. And after that car spray paint.
If there are more questions I'll be happy to anser them

Hat off! Hard to believe this truck started out as scrap cardboard! :jaw:

[PetervR]

well it is "a piece of scarp"
even the stuff I used for the indicator lights lay on the ground next to a pole on a parkinglot

and I havend done anything on one of the two trucks the topic is about. zo nothing new about that

[PetervR]

HI.
just had a good weekend of modeling. just not that good in taking picture's
I had put the resin over the otherparts of the cab. and it needed to set.
in the dryingtime. I started the tipperbox of the 4x4.

http://www.mtc-techteam.nl/daf16002061.JPG
http://www.mtc-techteam.nl/daf16002062.JPG
made uit of aluminium and some wood.

the semitrailer got some work to

http://www.mtc-techteam.nl/daf162061.JPG
basecally ready for the axles and wheels.

the cab after the resin was dry. got his plastic primer, primer/filler, putty, primer, and some sanding
http://www.mtc-techteam.nl/dd162062.JPG

I also decided on the "look" of the 2 trucks. the tractor trailer is supposed to look like it's just at the end of restauration. the 4x4 is going to look like its in use for some years, but maintained, and not completly worn. so flat paint. some rust. maybe a cracked window. no big dents, strait fenderd. maybe a torn mudflap. that kind of stuff.

[Rakthi]

Great job on that tipper box! Will look great "used" - Still hard to believe that cab is made of cardboard. :)

[PetervR]

this project just hit a hugh speedbump. my car broke down, and I need another one. so the finances reseved for this project are needed somewhere else.
now I have 2 choises or 3 actually, 1 sit and wait till I have enough to buy the parts I need. 2 built all the parts I can and buy the rearaxle and wheels later. 3 build some other cabs to sell. and buy the parts I planned. I could mix option 2 and 3, but in the time needed to build the parts I can build a cab.

grtz PetervR

[PetervR]

just a little update. I decided on builing a cab to sell. and buy the parts I can't build.
so just dividing my time on the projects at hand.
I have the torpedo chassis at the right lenght. and the sparewheelmounth on.
http://www.mtc-techteam.nl/dd161571.JPG

the 4x4 had a little work in the tipperbox.
the mechanics will be insired on the carson tipper system. with the motor for the system under the cab, and the drive motor will be mounted between the chassis. like the original asiatam chassis. there will not be a problem there

http://www.mtc-techteam.nl/daf16001571.JPG

http://www.mtc-techteam.nl/daf16001572.JPG

the frame rail of the tipperbody is just put on there with double sided stickytape. it needs some adjustment

[Doggy]

You got skilz! What do you use to smooth the cab? I tried o play with some putty for plastic models, but didnt really like it. I dont know If I did something wrong, or there is something more that needs to go on top. When I sanded the putty, it would smooth out, but I would always have a line where the putty stops and plastic begins. I couldnt smooth that transition.
Am I just lazy or do I need more different stuff to put on?

[PetervR]

hi. getting it smooth is not that hard. the way I treat my models. is like it are real trucks.
the stuff I use comes form the carparts store not the modelstore.
an other thing is the line between putty and metal wood or plastic will show. the simpelest way to prevent that is to cover it all with putty. and have "the line" on a spot where it's oke to have a "line".
I have multiple layers of primer, filler, putty and sprayputty. if you want a brand. Motip paint and primer, and Alabastine carputty and sprayputty

grtz PetervR

[Rvjimd]

Very interesting!

About the resin, is it a single component? Not two parts with hardener? How long or how slow does it finally get hard to sanding stage?

Thanks for all the info!

Jim

[PetervR]

the resin is a 1 component. the setting time is a few ours in the "cold and dark" and about half an our on a warm sunny day. I usually apply it last thing in the evening. and next morning it's set. to make it compleet
the putty I use takes about 10 to 15 minutes to be hard enough to sand.
the sprayputty takes about 5 to 10 minutes to set.
at this stage I use 180 grain dry sandpaper. just befor the colorpaint. I use wet sandpaper 280 of 400grain.
just as importand. let the sandpaper do the job. don't push to hard.
and this is for the torpedo.
the 4x4. I'm going to experiment with it. so failure is an option. it will get acrilic paint, form a tube. and I'll brush it on. It will also get some 2 component rush in some places. this way it's easiers to weather the truck.

[PetervR]

HI.
just last week your dogs chaised my daughters cat though the house.
with a predictable end result. the dogs still chaise the cat. and the 4x4 droped of the table.

http://www.mtc-techteam.nl/DAF160027071.JPG
http://www.mtc-techteam.nl/DAF160027072.JPG

it looks bad. but this is a cab originaly build to be a positive mold. not to be the cab on the truck. and it had a few weak spots I just didn't know to find out this way.

it's glued back in place, and I took some time to think if I was going to use the accidend to wheater the truck and put some rust around the crack, or make it smooth with putty.

yesterday I made it smooth. and I'll weather it in the spots I want

[PetervR]

just didn't put a picture of the rebuild cab here.
http://www.mtc-techteam.nl/daf160028072.jpg

and I was talking about weahtering this truck just a little.
I found this picture on the web and I like the way it rusted. it might be like this one. but in red.

http://www.mtc-techteam.nl/daf160028071.jpg

just started planning the rust. up to now I was working to get a smooth surface. with a neutral color. because the red I'm going to use is a bit transparant. zo next up is braun. than salt, than the neutral color, than the red. and than let magic to it's thing ;-)

[Finster]

I'm glad you were able to repair it. It would be a shame to put all that hard work into it and not be able to use it at all.

[PetervR]

A little color on the torpedo

[Roundabout]

You do some really nice work, amasing what you can make out of cardboard.

[PetervR]

Cardboard works so much easier than plastic. Just bending without heating it
Sanding the basic shape is just a minutes work. And after the quick and easy build fixate is all with the resin. Well basecally the same way Formula 1 cars are build. I just use cardboard instead of carbon. And my resin doesn't need to go into an autoclave ;-)

The crashed cab just got some rust

The salt technique doesn't work without the airbrush. Luckely rust comes in more shapes than one

[egronvold]

It's turning out great!

[PetervR]

well I'm back online.
the two trucks made it to the show they were build for. but not completed.
and even unfinished they where noticed.
having been side tracked by the fleu, a cab build for a clubmember and another daf truck. I will tell all about in an other tread.

now to get them going again. the first to get finished is the torpedo truck and trailer.
I had figured a way to make the rear fenders. ofcourse made uit of cardboard. just when I was happy with them, to take pictures of them. the cat though some hairballs allover it. and the cardboard socked with all the jussy bits. So there was just one thing to do. No not kill the cat. thow out the fenders and start over. the starting over bit will happen in a few days.

[frizzen]

That's really impressive! i had no idea cardboard worked that well for building. Those bodies looks great.

It sounds like Cats are bad.

[PetervR]

just got myselve a rear axle from china. it's just to wide.
the discription stated it would have a diff.
narrowing down an axle I can manage. making a diff. is just out of my leage.
after resieving the axle it appiers to be a locked diff.
after getting it apart it actualy has a diff. after putting it together again. it is not completly locked. but it needs to gain some "play".
also orderd a motor and other driveline parts.
also found someone to make me some tyres for e nice price. this one can get going again.

[markturbo]

I've never seen a build from card board before, very nice work there. Good to see you're back to building.
