Default My first home made model engine The Boll Aero 1,8

Hallo Model engine friends from all over the world.

I will start this new thread with a couple of words to thank Mr.Chris Boll from
England for all is help and advice when needed during the making from my engine and of course for his nice design from a simply constructed model engine which the Boll Aero 18 is.
This model engine can also be built by people who have n't lots of experience in working with "High-Tec" maschinery and constructions in metal and aloy.
I hope that the photo's made during the production from my Boll Aero 1.8 will
give the readers/visitors of this website the enthousiasm of making such an engine themselves.


Greetings from Modelmotor-Europe.

Hallo Model Engine Friends,

Enclosed i send some photo's made during the production from my Boll Aero 1.8 cc model diesel engine.A Glow version was made as well,but this version performed not OK enough so some of the Glow parts need to be tested some better.The photo's made from my Glow Boll Aero 1.8 can be seen in this thread as well only to give you an idea what's looking like.I made a couple of Boll Aero 1.8 model engines so i did make some more engine parts as well.

many greetings from modelmotor--Gerard-The Netherlands-Europe.

Hallo Model Engine Friends,

Enclosed as promised some photos made from the parts and complete Boll Aero 1.8 Glow Engine!
As already said the engine is in a stage of development so this is just a try out because i am not so very familar in building my own model engines.The 2 Boll Aero 1.8 engines,Boll Major 4,4 and B.J.Cicada 1,4 engine are my first steps into the magic world which is named/called "the self made model engine world" and i like it very much i can honestly say.

Many greetings from modelmotor-Gerard-The Netherlands-Europe.

Pic or ten says alot, this is the engine I try to my first actual fuel going engine. Really appreciate these pics, somehow i missed bronze bearing and was wondering how will it cope all the revs. Still doing just preparations and some maintenansing to my mill and lathe, but after all dro's and rotating tables are final done, I'll get there. (currently building some sort of diy bandsaw)

Hi Gerard,
You are my inspiration and ''Hero''.
Will finish up my half-baked Bolero done 10 years ago. I sort chickened out because,I lacked some of the skills.
The Bolero is a very simple and yet very skill demanding and very unforgiving engine.
Now about to finish up and run the Nemett-Lynx Engine after successfully built and ran Webster and Rupnow Engines.These engines are very forgiving.
The Bolero will be next after I recover from ""Lynx'' Burnt-Out.

Default Boll Aero 18

Hi Gus,

Thanks for the compliments about my Boll Aero 1.8 home built engine(s).
These engines were the first steps to home model engine making.
I am sure with all your experience that you will succeed in finishing your
Boll Aero project also with sucess.
I ran the Boll Aero for several weeks ago now ,but it did n't perform as good
as i suspected.
I must admit that my Diesel fuel was far from OK because of the fact that
factory made model engines also had big problems to start and run a little bit decend on that old fuel.
I will make some new fuel in a while unhappily i do live in a part of the small
town with many houses so also many people living together which will give big problems with the engine noise.
I will let you know when i have run the engine again.I hope to hear from you when you start finishing your Boll Aero engine and in the meanwhile lots of sucess with your today's engine projects.

many greetings from modelmotor-Gerard-The Netherlands-Europe.

Default Boll Aero home made model engines.

Hallo Gail and Hallo James,

I apologize for my delay in sending a reply.
I thank both of you very much for the compliments i received on my Boll Aero 1.8 home made model engines.
The Boll Aero 1.8 was my first step in selfmade model engines and i was
very happy that i suceed in building them
I have made after the Boll Aero(s) 1.8 the B.J.Cicada in a kind of old school style
and the Boll Major 4,4 cc which is a very powerfull model diesel engine with much torque at a low RPM.
The last time i have done some research after a new small model engine project.
I think that my choice this time will be a also symple to construct model glow
engine.I choose this the Little Dragon 1 cc a model glow engine with rear rotary disk valve induction.
The engine is a design from Mr.Roy L.Clough JR'S who did a very nice job by
designing that little model glow engine with a cilinder displacement of only
1 cc.
I hope that this engine gives me the chance to continuate model engine making after a year of illness in which i nearly could n't do a thing.

many greetings from: modelmotor-Gerard-The Netherlands-
Europe.

Gerard,
I built a Little Dragon some time back. It was a fun engine. For readers not familiar with it here is a photo of mine.


And a link to the build log on Model Engine News.

http://modelenginenews.org/lildragon/index.html

It was not a brilliant performer but has great historical interest as it is one of the first designs using the recently developed glow plugs.

Another engine of similar size and using similar construction methods is the PMC IMP. It is a side port compression ignition engine however.



Very glad you are able to get back in the shop.
Gail in NM

Default Little Dragon

Hallo Gail,

Thank you very much for your post Gail with photo's from your "Little Dragon" model engine and the other IC model engines you made during the time as well for the very sympatic words that you wrote down.
I must say that your self made engines looking great and show a high grade of craftmanship which i mis at this time,but hopefully time will teach me enough to reach a higher standard in metal working.I train myself each time in taking enough time to make engine parts on a higher quality level.
Unhappily i do n't have the possibility to make use of CNC metal equipment
which would work much more presicely,but the mainpoint is getting
enough experience and patience to do the job properly.
I should like to have some more contact with you by e.mail in the nearby
future when i have questions on which might have a much better answer
or advice than i have.
Thanks as so far for the very good contact Gail and in the nearby future
we will contact each other by e.mail.

Many greetings from: modelmotor-Gerard-The Netherlands-Europe.
