ENGEL VII42/C Build report

Hello all,

After building the Engel Gato I have chosen as the next project the Master scale Type VII /c the most used German U-Boot.

After building the Gato with all his triumphs and difficulties I trust that I can coop with the building demands this Sub needs to make her looks and working nice.
There not that many Boulder reports as far I know off, and mainly the sailing part is missing in most reports.

Well this one must sail.

After buying by Internet the waiting begins for the packets arrives.

And after four days they came

BIG BIGGER BIGGEST


In the little Box are the resin and brass parts nicely sorted.



Look at this,,

The stanchions all ready.



The Guns,



Tower,


With Brass exactly fitting deck





The nose cone and electro motors unit waterproof tested till 12,5 meter
And ready to run.



And a lot more of all this nice pieces.

Then I opened the BIG box with the Hull inside.

And Engel knows how to pack his stuff.







And in close-up really very nice craftsmanship,






So you understand that I was very happy to see this high quality because its not a cheap kit so I expected a lot and it worth the money but its not a easy kit to built.

But it looks easily and there a lot of work being done already, but all the flood holes must be done by myself.


There are more than 1000 so I'm busy for a wile.

However I started with the Techrek.

The plates with CNC abs



First I put together the Motor section.





And it fit perfect.

Than the section on the top of the aft dive tank.




Then I made the revolver section were the battery's must fit in.

And on top of that the second dive tank will be fitted.
And than its look like this,


And it really looks great and its tall also



It fits almost without any flaws, But there was a problem with the frame extension and one of the switches of the front dive tank.



And I can not find any reason why this frame are located there, so I take it away to make room for the switch..

So far the beginning of this report,

Greetings from Holland,

Jan,

Looks like a really nice kit, should be much easier to build than the Gato. Are you going to cut out those drainage holes by hand, rotary tool or do you have a mill? Any special features planned for this kit, like the mast and radar on the Gato?

Hello HelloMoto,

It looks easier indeed to build her but the real challenge will be mounting the WTC into the Hull at the exact spot so the fixing points fore and aft are at the same spot and I'm indeed using a Dremel moto tool with a 1mm tool to cut out the drainage holes and the rest by hand. I put in some photo's to let you see the progress.


And some details,



And some deck details,



I do about 20 holes a day to keep it funny and when it go's very good I do 50 holes and then I stopped because my focus will be lost then

I continues also with the WTC and build the Nose cone together.



And the assembly completed with the energy-coupling.


You can nicely see how the electrical pcb boards fits together.
There one board with spring loaded runners.



And the second board that accepts the runners,



And here the completed assembly,



So I'm going strong

Greetings,

Jan.

Hello all,

I have finised the WTC and its now inside it's tube
And its fits beautiful however all the electronics are not fit yet.

The nose cone without the O-Ring



The WTC insite the tupe,



And the backside of the drive unit with the water inlets for the two water pressure sensors and dive tanks. And the holes for the two steering arm's. And of course the two main shafts.




Then I did some grinding and carving with the moto tool.

The front main deck is DONE




And some detail of the Gun support ,




And the front Resin deck latch and they are softer than Epoxy so it go's faster but also faster wrong
But not a problem when you take your time.



And the finished aria behind the Tower,



I use a proxon 18volts moto tool and a Dremel 220volts moto tool and its a good combination for this kind of job.

The Hull looks just wonderful with all his holes and shapes......

I'm a happy man, but there's still a lot of work to do.

I'm started with the stern hull now.

Will be continued,

Looking good! How long did it take you do all those holes? I always thought it would take absolutely ages to do by hand without a PE deck and that has always put me off these sort of boats.

Hello HelloMoto,

It's hard to tell how long it has takes so far, and I started this project in January so its not done in a few days. only the last days its going fast now

But if a man was able to maintain his accurateness then expect I that this job can be done in less than 30 hours.
But you will hate this hobby for always after done that I guess

Best regards,

Jan,

Interesting way that hull is moulded, the lower hull is clearly two pieces, which it would have to be to clear the undercut. The deck looks like a one piece mould though, that perhaps is glassed in afterwards?

Is the hull polyester or epoxy resin?
