V2 rocket

[fledermaus]

Hi my friends!
Work on the Meilerwagen continues, more details added on different areas.

the rear air tanks for the brakes received some details

the air valve is 3D printed

the valve is glued to the frame, brass wire is used to make the air lines

next the rear wheels boogie received brake lines details

I wanted the rear boogie to turn so I cut the shaft and replaced it with a longer one made from styrene rod.

the brake line tee is added

next I tested the locking bar for the rear boogie and found it to be shorter than needed for it to work, also constructed the channel were the locking bar "locks"

the kits locking bar

the original bar and the styrene channel

the channel is glued in place

the new 3D printed locking bar

the bar is drilled and a piece of brass wire used as the pivot bolt
also made the bases for it from styrene

the locking bar is glued in place, here the new styrene shaft can be seen

a handle bar is made from brass wire, it moves!

another view of the channel location

here the bar can be seen in its unlock position

and in locked position to prevent it to rotate

side view of the locked bar

Now the front locking bar is also modified so it works
I started by cutting the bar from the lock frame

the pivot ball is drilled to accept the new styrene shaft

the molded on lock pin for the shaft is removed and replaced with a piece of wire

the new shaft is glued to the frame

here you can see how it works
the shaft is inserted on the pin so the boogie can turn

here the locking bar is lowered and secured to the front of the boogie so it cant turn, this is used when you want to pull the trailer from the back. the bar pivot lock pin isnt attached yet.

some of the reference photos
here the front locking bar in locked position, note the bar pin

and in unlock position, the pin keeps the bar straight in up position

the rear air tanks and connection lines with valve

rear lock bar in locked position

the rear lock bar can be seen in unlocked position

thats all for today, still lots to do

thanks!

More work on the V2 trailer has being done, so here it is

after figuring out was this part is for I started to modify it to make it work

the kits part

I started by cutting the round pivot base

next I drilled the sides and reattached the base with cooper wire pins

now the base can pivot

the other end of the rod is also drilled so a securing pin can be used
on this side

finally the pivot base is drilled to 2mm so it can be attached to the trailer with a styrene pin

the pin is made with styrene rod

the completed pin and modified part

the trailer hole for the pin is enlarged to 2mm to accept the pin

the molded on pins on the back of the trailer are carefully shaved and the area drilled out to accept a pin made with 1mm styrene rod

the molded on pins are removed

new holes for the styrene pins are drilled

the shaved handles from the molded pins are glued to the new pins

the brackets for the stabilizer arm rods are drilled

the parts ready to install

the pin is ready to install

the molded hook that holds the end of the stabilizer rod is replaced with a piece of cooper wire

the rod can now be turned to the interior and locked in place

it looks like this in place, the rods are used to reinforce the frame when the stabilizer arms are deployed, when the trailer is pulled from the back the rods are closed to the sides so the towing arm can move side to side

new locking pins are 3d printed to hold the stabilizer arms rods in open or closed position

pin used in closed position

pin in open arm position

and some reference photos

thanks for watching!

So, at the end of all things, is this trailer a launch vehicle or is it just for transporting the rocket? It's really cool that you made the outriggers poseable! It hurt my bwain until I understood what you were up to! Ach du meine Gute!

Lovely work!

@Rhino The trailer was only for transport and I believe it tilted the rocket up to place on the small pad. Then it was removed to a safe distance

Looking really good there Abdin! It is always interesting to see how the assemblies actually work.

Guys thanks! Rhino the trailer served as transport to the launching site, then it is used to erect the rocket and place it on the launching table, as a service platform before the launch, and it also can supply fuel to the rocket if needed.
