Aichi "Hansa"


Recommended Posts

Thanks for the info Hubert. Maybe no secrets, but excellent advice all the same.

 

I have a guillotine-type chopper for cuts, with the the same rasor blades, but could not use it for these parts as I cannot set the length properly for very thin parts. The shortest I can do using the chopper is about 1 mm. It's a wonderful tool however for multiple parts, with consistent lengths and square cuts (or angles ...). I cannot recommend it enough if you do not have one. It really changed my modelling life for these kinds of cuts...

 

Where did you get it from Hubert? Sounds like something I need too!

outstanding work on the engine and carb. Your attention to the detail is amazing.

 

Im glad you are back from your holidays, i was starting to go into withdrawal for lack of Hansa fixes. :lol:

Sabre

 

Thanks Sabre.

 

How about a Wal cure to fix your withdrawal syndrome ? That would also fix my wthrawal syndrome ! :lol: :lol: :lol:

 

Take care.

Thanks a lot gentlemen. To receive appraisal from such masters as you is truly heart-warming B) ...

 

OK, time for the daily update... :)

 

Been spending most of the day on this engine. Does not seem much has progressed, but doing the paint touch-ups and the tiny bits was time-consuming...So I now have two exhausts-collectors. The Hansa seemed to have an exhaust collector with the gas exhaust at the front. I did interpret the very hazy and black phoos I had, and this looks a reasonable reprodcution of the real thing to me... :rolleyes:

I have aslo done the 16 sparks. They were made out of 0,085 " EG rod, turned to a proper conical shape into the mini-drill at slow speed. Ensuring they are all aligned and the same protruding lengthe was a concentration exercise..

 

Finally the "pièce de résistance" was the assembly of the carb over the engine, with its four protruding pies connecting to the cylinder heads. sometimes I wish I had more than two (clusy on top of it) hands. <_<

And I could not resist a blank trial of the engine in the fuselage...just to find out I had positoned the engine craddle too high, with a consequent wrong propeller line thrust. :angry: :angry: After some carful dismantling of the already glued bulkheads, and mods, everything is now back in order...And the engine fits just right bteween the bulkheads ! (YES ! :P :P :P I'm glad I id my plans correctly because I never thught of checking this one out whne building the engine ... ;) :lol: :( )

Need to add the piping to the engine now, and the spark wires, and then I can move on to the radiator and the fuselage !

 

More tomorrow.

PS: as this is about sharing experiences, I forgot to mention my (very) happy experience with Prince August / Vallejo acrylics. I used to brush-paint enamels, and always sturggled with Tamiya or Gunze acrylics with a brush, and did not like the dilution process of any kind of paints for the airbrush...

 

Well all of this is behind me, now that I found Vallejo: it brushes very well, airbrushes like a dream without dilution (al least in my gravity-fed Paasche Talon), gives a very fine and smooth finish, has great metallic colors, and finally dilutes and cleans with tap water ! Add to that a convenient soft-vinyl "squeeze" bottle which gives you very precise control of pouring (remember the PITA of pouring paint in the airbrush cup ?), and I am now sold on this range ! I might even start liking painting my models :rolleyes: <_< :lol:

 

Where I am living the range is held by a small shop specialising in "Dungeons and Dragons" games, so the paint range they hold is somewaht limited and biased towards elves and knights, but I have found mail-order shops in France with a very comprehensive range of Prince August / Vallejo acrylics.

Time for the new update...Days are really short, or I am very slow ;) Somehaow, I always expect I'll do more during the day Than I actually achieve...

 

Anyway, finished the engine today (well almost as I need to add an oil tanks with its pipes, plus the fuel line and the gas wire, but to do this I need to install the engine in its cradle in the fuselage....)

 

Like I guess everyone of you detailing an engine with its spark plugs, I found this exercise pretty painful. :lol:; any building that requires using CA glue for an assembly is actully a real PITA for me :angry: :D :angry: ;) , even more today, when the air was so dry the CA glue took ages to set :angry: . My wires were a bit thin, but these are the only ones I found in my box...The good thing about old engines, is that they used materials like brass or copper or steel for the pipes that can be replicated using wire of the same color, avoiding the dreadful painting exercise....All in the Hisso looks good I feel :P

Talking of painting, even though this is not my favorite exercise (what an understatement :lol: !), I had to really tackle some of it if I want to move to the end of this build. I have thus finished the bottom part of the fuselage, and painted the three parts trying to replicate a wood texture. The paint on the photos is barely dry...Let me know whatt you think of the result.

And finally, my shot with thee dry fit of the fuselage and wings, this time with painteds insides and a bottom fuselage ...

:P :lol: .......... ;) Uh yeah, Hubert......I do believe that will do? :huh: Whoah, outstandingly awesome craftmanship dude. Whoa. Sheesh, you don't even mark or mess up your cutting board! How do you do that? heh heh. Can't wait to see the next progress pics,and it's good to see that you're enjoying your time off! ;)

Thanks for the comments, Russ. I am learning and taking inspiration from your work ... :lol:

 

OK, time for a new update...I have not been idle in the last three days, far from it, but I have to admit I am a slow builder, and also that I just love trying to go as far as possible in detailing, which takes time...

 

So what's the output of those last days? I worked on the innards of the beast, mostly the cockpit components. The WB29 was fairly spartan, and so was the Hansa I guess, but there are still penty of small interesting details to add, like :

 

...the manual priming pump for the engine. teh WB29 had one. I am not sure for the Hisso-fitted Hansas, but that makes for a nice and origibal detail...

 

2009_0824AF.jpg

 

...the control wheel ...It's a lot more interesting than today's HOTAS' sticks, isn't it ?

 

2009_0824AD.jpg

 

...the rudder pedals. I corrected my initial arrangement for the wing spars, which was functional, but had nothing to do with the reality. The problem is that at least the front spar is visible through the pilot opening. I had found while roaming the net, three marvellous pics of norwegian Hansas, stripped down to their basic structure, which have proved invaluable in the detail work of the inside. The silver box behind the rudder pedals is thus close to the real aircraft, and housed, just like my kit, the front spar.

 

The pedals and their stirrups, and the mounting of the rudder bar, conform to the original, even though I suspect not much will be seen when the fuselage is finished.... :rolleyes:

 

2009_0824AI.jpg

 

...the petrol tank and the pilot seat. The pilot was seating right on top od the petrol tank, with a system to set it lengthwise. Clearly engineers did not fear the dangers of combat fire at that time ...the seat is yellow, as this is the base for subsequent wood texture work...Other areas are also yellow for the same reason...The petrol tank will hide the structure for the rear spars.

 

...the observer's seat, which was was a foldable fabric thing on a tubular structure...

 

2009_0824AG.jpg

 

There was an observation window in the bottom of the observer's pit (you can see it in the bottom fuselga pics). I was wondering how he could stand up and use his machine gun in the WB29 without falling through. I iniially thought that there was a kind of foldable wood shutter, until I took a further look at the above mentioned norwegian piccies. There it was, visible through the "window" : a grid structure, which was a fairly neat solution to ensure a solid foot base for the standing observer / gunner, and yet maintain a capacity to see through...So here is my rendition of this grid...

 

2009_0824AH.jpg

 

Finally, the photo in the first post of this thread, which the A/C I am aiming for, shows that there was a windmill electricity generator on the left wing. I suppose that was for a radio, especially as the the MG were dismounted at the time when the Hansas had their 4-bladed props. I therefore imagined a radio to be plced in front of the observer. My rendition is purely conjectural, but based on some radio gears of the Dornier WAL I had, knowing the WAL was almost contemporary to the Hansa, and there were significant exchanges between Germany and Japan already at that time. Anyway this the radio I imagined, a fairly hefty pice of gear (another good reason to dismount the machine gun), with a morse transmitter, and a an old fashioned microphone, and a reel-up antenna...The dials on the radio are part of the work I did to design dials and instruments for the dashboard, using piccies from the funatsu site, and a vectorial-drwing software...it took a few hours to achieve, but the effect is nice... :P

 

2009_0824AE.jpg

 

You can't see the dashboard on the pics, because it is still down to basic components, but the dials are ready to install as soon as the dashboard is painted in wood...

 

So that is all my work of the last three days, including the not visible lights for the control cables in the bulkheads. I am back to work tomorrow morning, and will probably have no time for modelling in the evenings. Even though the fuselage assembly should go pretty quickly when the inside is done, I doubt I will be able to meet the deadline, but I will be close !

More to come ! Thanks for looking.
