1930 Bentley Blower by Aifix 1/12 build log [COMPLETED BUILD]

[François]

When I started this project, one of my goals was to have working brakes. To achieve this, I needed working brake segments. So I drew them up and printed them with the only printer I had at the time (a filament printer). So I had my brake segments which eventually gave me working brakes. The thing is, I now have a resin printer. Sooo, me being me, I had to redo them. Here are a few pictures.

First, here's what the kit proposes


These are the segments I printed first


This is what I really wanted


And this is what I now have. Still need to make the return spring.


it's really nice to be able to do praticaly any parts at will!!

 

[François]

I made the micro springs for the brake segments using a. 003in dia rod.

I reprinted the brake drums




And finished wiring the head lights and the gearmotor. All the wires run inside the frame and all come out on the left side of the gas tank to form a neet wire harness that will eventualy go to a control panel mounted on the display case. I also wired and installed the battery.

Hi Francois, since you started the build, every new post tells me that you are the real craftsman, however, every new post continues to wonder me how far you can go with showing details on your model, and trust me, I wouldn't surprise if one day, you turn the ignition key and the engine will start!

 

[François]

I did the exhaust system. I wrapped the down pipe, added tube clamps with expension springs before and after the silencer and added the correct tail pipe mounting bracket.

The real thing


Tube clamps and springs



Tail pipe bracket


The real thing


I also decided to try my hand at printed the wheel rims instead of drilling a zillion holes in the kit rims. First try is promissing.



And lastly, here are some general shots of the car with the body on

Like mentionned on my previous post, I tried printing the wheel rims instead of drilling the ones from the kit. Well after a few printing interrations, I'm very happy to say that I was able to print a very nice rim. The prototype rim (all the pictures that fallow are of that wheel) was printed at an angle, the finished rims are printed flat and the result is even better. So here are some pictures from start to finish with, as always, a few pictures of the real thing.

The rim fresh off the printer, printed at a slight angle


I made an assembly jig to aid the alignment of the first row of spokes



First row done


Second row


Wheel completed next to the kit's wheel


Primed


And painted. The prototype was painted after lasing but the proper wheels will be painted in sections, the hubs and rims will get a coat before lasing and a final coat over the finished wheel. I believe that the result should be better this way.


i also printed a valve


And a bunch of wheel weights



The finished prototype wheel




The real thing




again the real thing


And for fun,
the model

Vs the cad model

That’s a great work, François. The spoked wheels with all the details looks beautiful.
Regards, Peter

 

[Uwek]

Great details on the wheels - I love this model (and your work)

 

[Corsair]

wonderful job ! It somewhat reminds me of the Pocher kits.

Hello Francois!

Happy New Year. It is very nice to catch up with you on this forum. I will follow your build. It looks great.

 

[François]

Happy new year Rick!
Thank you, I'm very pleased with it so far. I decided to go all out on this one, working engine, working brakes, working head lights, and many more features still to come.

 

[François]

Had a bit of bad luck with the head lights assembly. The 'U' shaped bracket that holds the head lights is so fragile that it keeps braking. So I did what I should have done in the first place, I made it out of a brass rod. I had to slightly modify the horn bracket to have a more sturdy assembly.

The new 'U' shaped bracket that is now more a 'Y' is made of soldered brass rod, round and square brass tubing. The lower rod will go thru the modified horn bracket and also thru the frame.



I also made the spare wheel mount with a screwed on center spigot for easy spare removal


And the real thing


And lastly, l made the step. I might need to rework the shape a bit but it pretty close.
This is the kit's step

Mine

And the real thing


I'm also slowly advancing the lacing of the wheels. I've pre-painted all the hubs and rims

Your work is really fascinating. As you probably know, I have been selling Pocher models for almost twenty-five years now, and I always considered them a sort-of guide to creating the model. Of course, when the brand was started in the 1960's there was no thought of 3D printers but I wonder if your work here is a preview of what modellers will be doing in the future.

Do you think there will be companies that will sell some rough CAD files to a model, and include a zillion pictures? That way, the modeller would have the fun of finishing off the CAD, and then printing on their own machine.

Being a model designer, and retailer, I am always anticipating where the industry will go next.

Best Regards,

Rick

 

[François]

Thanks Rick, coming from someone with as much experience as you means a lot.
There has to be a market for this, especially with the increasing quantity of affordable 3d printers out there. The problem is that not everyone who owns a printer has the ability to model complex parts on a cad system. That's where I come in, I've started offering my 3d cad modeling services to anyone wishing to further customize with a level of detail that scratch building is often not capable of giving.
Naturally, I can also fo the printing.

Hi Francois,

If you are interested, we should take this off-line here and discuss over a coffee. I have the website where we could market what you design. I think the folks on this forum might benefit from such a collaboration.

Cheers,

Rick

Finished reenforcing the head lights assy, shouldn't brake anymore.


Now that that's done, I decided to tackle the radiator.
The kit's radiator is composed of 3 parts:

1-the inner part that represents the core (right), I'll completly replace this part because it not very detailed and it doesn't fit with the twin fans and water pump.

The kit's core with the grill removed


A real core

My core so far



2-The outter shell (center). I'll keep the kit's part but will replace the poor excuse for mounting brackets that are there by more accurate looking brackets.

The kit's bracket

Real thing

First test print


I know that many say that the bentley badge location is incorrect but personnaly, I don't find it too bad. I think that playing with it would only make it worst since this part will be chromed.


3- the grill, I will also redo this completly


As a side note, I was recently asked to 3d model and print a model T tire in 1/25 scale complete with the firestone logo and a specific thread.
This is what it looks like


And a vintage light. Again in 1/25 scale. The post holding it is a toothpick!! This was a mis printed part that I painted real quick just to see the color scheme

 

[rshousha]

Hi Francois,

How do you do this? It seems you work 48 hours out of every 24! Well done!

 

[François]

First test print of radiator core, not half bad. I'm still missing some details but at least I know it prints ok. I'll be using a very fine flexible wire mesh that as an aperture of .02 which should simulate the core's mesh pretty good. For the front grill, I'll use the same metal mesh used for the head lights.

 

[François]

I had pretty much finished printed the different components for the radiator assembly when I noticed I made a mistake. Here's what I did wrong. There is a type of webbing inserted in small slots that goes all around the core's outter flange.

Here's what I'm talking about.

When designing the core, I missed one of the slots for the webbing, the result is a broken pattern.



I'll reprint it. The rest of the parts are ok.
