The carriage is now ready and moves as it should be .

Obrázek

Then came today finally the post with the support of the visor cover , and ....... well ........

Obrázek

So I can not build a movable sighting device as Ralf wants. So I tried very carefully a little to turn everything straight.

Obrázek

It almost I succeeded , but it should not be.

Obrázek

Since I will probably have to build the bracket as well as the visor plate new.

Before I begin , I had but that the support level and adjust the visor cover of rounding . The cover was also slightly bent and lay diagonally on the cover, so yes what should not be. So the surface ground flat , directed the lid and adapted to the curvature of the lid vorsicjhtig with a polishing wheel .

Obrázek

And so it should look like ...

Since I do not trust the visor cover if I wanted to make them straight , I make a New 0.8mm aluminum.

Since my front guide is indeed broken when straightening I do the New also made of aluminum , which is not so easy in the filigree part .

And now glued .

Obrázek

And now I 'm going to design and build the mechanical and internals for Kannonenefolation . Since I now use my 3D printer.

Obrázek

Morning the parts should be ready ready.

Now that the print overnight was done I had these parts in front of me .

Obrázek

The support that is built to support the prints in the implementation of the joint was removed quickly and easily.

Obrázek

When ball joint I've cut off the screw and ground over something . So I could pipe the rocker after I had this even minimally reworked simply push on .

Obrázek

The driver for the gun barrel I have also included.

Obrázek

On the rocker I immediately suitable mounts for the servos provided what it looks like this .

Obrázek

But anyway , I have something I must change .

For the lateral direction , which operates simultaneously as a twist I have to make the bracket for the deflection again again and then also equal to a suitable servo mount . By the way me a very simple mechanism is still remembered so that it rotates to fit the visor in lateral alignment of the cannon. For that I have the drawing again supplemented and print the up again tomorrow from .

Obrázek

Obrázek

So I have when required , or if it is to have someone complete a print file of all parts always have .

Nice and slow one end of my work on the Ferdinand is foreseeable.

I 've now designed and printed a simple driver for the visor .
In addition I have glued a long hole tab on the side of the rocker .

Obrázek

A stamp on the underside of the visor then later glued and this takes the visor then the lateral straightening.

Obrázek

But it goes on first with the redirection page for straightening. The I also have a little improved.

Obrázek

The lever of the deflection do I feature a brass profile I drill identical for all three levers.

Obrázek

Obrázek

Fully assembled it looks then like this. Here already the ball heads.

Obrázek

I also screw each at the top and underside of the rocker a ball , since the articulation of rotation is the same .

Obrázek

And so it is then assembled later.

Obrázek

Obrázek

Then I have the power for the recoil and mounted for lifting and lowering.

Obrázek

Now that 's missing is the articulation on the fighting compartment roof for pipe evolation and two brackets on the roof top for the visor .

The holders of the visor are now glued . But this I first had to drill through the mounting points and also set a new one , as the Intended is the wrong place .
In addition I have pierced the roof with a 1.2 mm drill and freehand extremely carefully milled with a 1.2 mm tungsten carbide bur the slots . If it has no feeling but should rather be , since it can be an expensive quickly with broken cutters.

Obrázek

Obrázek

So I had to cut only two small brass strip , bend and push through the long holes . At the bottom I have then also bent and glued .

Obrázek

Obrázek

Obrázek

When, after the adhesive has cured everything was nice too smoothly , I can now start to assemble the mechanism.
