Brockway 459

[Jürgen M.]

Hi everyone,

long before I had begun the IH Transtar II which I finished a while ago I had started to design a Brockway cabover. Since I try to have at least one conventional and a cabover of one brand I thought it might look nice. 

These are the 3D drawings I made:

 Just the cab

and a virtual mock-up of the chassis with drive train and engine.

I put in a V8 since the 459 was the high powered V8 version. 

Now I have to design the interior, the tanks with mounts, rims, exhaust, air cleaner, ...

I already printed some cab parts and the fenders. I decided to split it up, sort of Italeri style, to get better print results.

They're not as good as I hoped but OK. 

I might try to hide the print lines a bit by painting multiple pin stripes or something! 

Sanding is merely impossible cause that stuff is much too hard. The parts would break rather than becoming smooth.

Primer only works a bit and putting on too many coats I would cover up details.

We'll see how it comes out!

Have fun watching!

[Gary Chastain]

Great subject matter, will be watching.

This will be cool. And you answered a question I had about how brittle the prints were. Also another wonderment is what kind of glue do you have to use? CA , I would assume. And thinking about the print lines, what about a very thin application of putty , that could be easily sanded and give a smooth surface ? Some water soluable stuff might work well….🤔🤔 just a thought.  This is going to be a great addition of a rare truck to your collection, I will be following closely.  Very interesting.  

[Jürgen M.]

Thanks Jeff!

The problem with putty is that it also covers details. I've tried it before and even a thin layer fills up door seems and other fine details and you hardly see rivets and prepared holes for mirror brackets and stuff.

For printed parts I generally use super glue. I've tried modelling glue but it only works on really smooth surfaces like sanded edges or to glue windows in place.

I hope this turns out nice. I painted the cab parts in the mean time. When they've cured I'll post some pics. 

[Jürgen M.]

The cab parts are painted. The stripes do actually distract a bit from the print lines. I also put a few coats of primer on and sanded in between. 

The surface could be better but due to the not really flat parts with a lot of radiuses it wasn't possible to make it smoother.

You can see the print lines in the pics above. Especially on the front part of the cab the lines are very dominant but if I had printed the cab in one piece or the parts standing up the window struts and seems would have looked terrible and would also have broken off while removing the support structures!

Hope it looks OK when it's assembled.

First I still have to design the dash. Parts of the interior are in print.

That’s an awesome paint scheme, Jürgen.  I hope Weihnachtsmann brings you a resin printer for Christmas - your wonderful designs deserve it!

[gotnitro?]

You beat me to a paint scheme! The annual Brockway homecoming parade and show is this wknd, their 25th anniversary, and planning on going. So far there's 100+ registered Huskies attending. 

[Jürgen M.]

Thanks guys!

I'm not sure if I really want a resin printer. I know of course how much better the print results are but I don't want all the mess and stuff. I'm not 100% off the idea yet but still sceptical.

Did I get that right? Is that homecoming parade a truck parade with Brockways? 

I'd be happy about some pics. Maybe you could share some? I'd really appreciate it!

Glad you like the paint scheme. I wanted something that distracts from the print lines!

[Gary Chastain]

Now that’s a cool paint job, love it. 

[Biggu]

I’m with the other guys JM, that paint job is stunning ! I love that. VERY well done.  That paint job would work well for one of your IH cabs too.  The cab looks great. I agree , it would be cool to go to a Brockway truck show. I hope we get pics as well …. Great thread, pal. 

[Jürgen M.]

Thanks Jeff!

Glad you like it. Hope it still looks good when it's assembled!

[Jürgen M.]

A mock-up of the cab front, fenders and interior. 

Still a lot of fine tuning to do. Straighten out paint lines, touch ups, sand edges, ....

The dash is in print. Hope it fits as well as the virtual one! 

[Jürgen M.]

Got a bit of the interior done.

Steering wheel, steering column and pedals are in print.

Tomorrow I'll get my window foil. I couldn't find the link where I used to order it so I risked Amazon. Found a 0.2mm foil. Hope it works! 

[Biggu]

Lookin good pal.  I really like the way you carried the orange trim into the interior. Nice touch. 

[Randy D]

Always enjoy watching you bring new and different trucks to life Jurgen!!!!

 

Randy

[Jürgen M.]

Thanks Randy! 

Never thought I'd get this much attention for this build!

It's not my cleanest build at that but I thought I'd build it anyway. It's also the first time that I build the cab first before even starting the chassis and drive train but I think I might keep doing that in future.

I believe it's of advantage concerning the precise connection of cab and chassis.

Some more progress in the interior:

The instruments on the Dog House are screenshots of original pics but from different trucks so they don't look as good as I hoped. Maybe I'll have to work on that!

The central instrument panel is self designed.

Next will be the cab sides with the inside door panels. Then the windows (if the foil arrives today as announced).

I over worked the instrument panels on the dog house. 

They're actually dark brown but they look red in the pic!

The right side cab wall fits!

Roof mock-up shows that it also fits!

Dunno what kind of printer you have, but I have a Creality Ender V2 and when I print stuff like that I switch my nozzle to a .02. It takes twice as long but a significantly smoother finish.
I did this KG a couple of years ago with a 0.2 nozzle. I did a little bit of sanding but not finish work. I don't have any pics fresh off the printer tho.

[BK9300]

Making great progress, Jurgen!

I have a Creality Ender 3 V3.

I've tried using a 0.2 nozzle but the results weren't better.

Thanks though for the tip! When I'm finished with this build I might do some more experimenting! 

[Biggu]

Your use of colors is amazing and well executed. I love the way you carried throughout the build. It all ties together nicely and great choices ! This is a really cool build. I think the instrument panel looks perfect to me.  I am really looking forward to your next update 

[Scott Eriksen]

I'm not a 3D printer guy but isn't the print line issue a calibration or how the piece is situated in the printer or how the supports are laid out? Anyway for the couple of 3D print builds I've done with blems ,usually just slight print lines in some areas I've used Mr Surfacer ,,,brush on and sand 

[Gary Chastain]

Great progress, love the color combination 

[meechum68]

Great colors! Like where this is going!
