Second Dragon 1/35 Heuschrecke IVb "Grasshopper" w/10.5cm leFH18 Gun
 
So I thought it maybe be a good time to publish these pics I took months ago, ostensibly or another "article" for the infamous Military Miniature in Review.:p
I apologize for the quality of the photographs- I went ahead without having the time or energy to get it set up better- oh well at least there is some sort of record. These photos take us through the construction of Voyager's ammo boxes. The first two attempts show me using the Voyager provided hinges, soldered on with two differing philosophies on how to go about it and the third attempt is using Aber's far superior hinges after i was found the Voyager set's were inferior.

Here is a group shot showing the planned aftermarket items to be installed into this build up.

The CMK kit for a Stug III will be scavenged for the front driver/transmission section, a detail not provided in the kit.

This is going to be soldering heaven, and here are my tools of war.

The main shell box parts cut from the brass sheet.

First I folded up one side's tiny lip with the Etchmate

Now the other side

http://panzerfaust.sslpowered.com/pl...rt%201-013.jpg

Next I used an etching tool to emboss the strengthening crosses on a piece of MDF.

http://panzerfaust.sslpowered.com/pl...rt%201-018.jpg

Some deformation occurred well I did this but it can all be smoothed out.

Good luck for the rest James...I like Grasshopper and watching your project...:)

Ruud 07-04-2009 05:28 PM

It looks like the PE train has left the station and your taking up the whole darn thing. Using any of the kit part in this build ;-)

later

nice, I have been waiting for this beast to be built

Well I'll post what I have so far- not much time these days for modelling...
Here the surface is smoothed out somewhat,
http://panzerfaust.sslpowered.com/pl...rt%201-020.jpg

Using an old Letraset dry transfer tool to hand machine the surface smoother.
http://panzerfaust.sslpowered.com/pl...rt%201-021.jpg

the reverse angle
http://panzerfaust.sslpowered.com/pl...rt%201-022.jpg

the big sides can be folded without the Etchmate with your hands.

http://panzerfaust.sslpowered.com/pl...rt%201-024.jpg

http://panzerfaust.sslpowered.com/pl...rt%201-025.jpg

http://panzerfaust.sslpowered.com/pl...rt%201-026.jpg

http://panzerfaust.sslpowered.com/pl...rt%201-027.jpg

Next time- I'm going to get a manicure. You have to know- as I work in the film industry here in Vancouver- my hands get covered in all sorts of paint and material. I paint sets for movies and TV. The last gig I was on was Stargate Universe and then recently I've been working on a feature called Percy Jackson. I apologize for the horrendous look my hands have in these pics.
http://panzerfaust.sslpowered.com/pl...rt%201-028.jpg

Here I am cutting off some hinge parts. At first I thought these would be alright- but in the end they weren't strong enough for much "hinging" if that can be a verb?
http://panzerfaust.sslpowered.com/pl...rt%201-029.jpg

As you can see there are two types of hinge part- a male and female as it were.
http://panzerfaust.sslpowered.com/pl...rt%201-030.jpg

Before I do any soldering the iron needs to be tinned.
http://panzerfaust.sslpowered.com/pl...rt%201-031.jpg

http://panzerfaust.sslpowered.com/pl...rt%201-032.jpg

http://panzerfaust.sslpowered.com/pl...rt%201-033.jpg

steel wool
http://panzerfaust.sslpowered.com/pl...rt%201-034.jpg

next dipping a brush into the flux paste I prepare one side of the hinge for soldering. It will have a little solder pre applied to it before it goes into position and then reheated, forming the bond.
http://panzerfaust.sslpowered.com/pl...rt%201-035.jpg

http://panzerfaust.sslpowered.com/pl...rt%201-036.jpg

some flux goes on the box. I shouldn't have done this this way, but you will see I devised a better method. The hinges should be attached to the doors separately from the box and then the doors added.

James Tainton 07-04-2009 10:24 PM

one part attached . Like I say I developed a better way of doing this- as will be revealed. For now, this seemed the best way.
http://panzerfaust.sslpowered.com/pl...rt%201-041.jpg

I use a combination of heat and tweezers to slide my parts into place, one of my secrets revealed
http://panzerfaust.sslpowered.com/pl...rt%201-042.jpg

http://panzerfaust.sslpowered.com/pl...rt%201-043.jpg

three female parts in place
http://panzerfaust.sslpowered.com/pl...rt%201-044.jpg

more pre-tinning of male parts...

http://panzerfaust.sslpowered.com/pl...rt%201-049.jpg

trying out some metal rod for use as the hinge pin.
http://panzerfaust.sslpowered.com/pl...rt%201-050.jpg

curling the male parts and the female parts into place over the rod. This is only a roughing out size- slightly larger than the final circumference that is the kit included metal.

rod removed
http://panzerfaust.sslpowered.com/pl...rt%201-054.jpg

tightening up and checking the fit with tweezers sans rod.
http://panzerfaust.sslpowered.com/pl...rt%201-055.jpg

here I am using the Voyager metal rod that is included - I found it to be really tough to work with, too hard to cut! I was abandoned.

http://panzerfaust.sslpowered.com/pl...rt%201-059.jpg

Here in the upper left you can see the hinge becoming un hinged. Back to the drawing board.

Here I am adding the ammo rack to the box,first adding flux to the area to be soldered and then dropping a tiny piece of solder into the spot. This will be heated from the backside which melts the solder into the seam.
http://panzerfaust.sslpowered.com/pl...rt%201-061.jpg

http://panzerfaust.sslpowered.com/pl...rt%201-063.jpg

http://panzerfaust.sslpowered.com/pl...rt%201-064.jpg

Now I've stripped the defective hinge parts off the box.

Separating the doors from the rest of the box.
http://panzerfaust.sslpowered.com/pl...rt%201-066.jpg

I used the other set of hinges from the set to try again-this time adding the hinge parts to the doors and box separately.
http://panzerfaust.sslpowered.com/pl...rt%201-068.jpg

Ready for mating
http://panzerfaust.sslpowered.com/pl...rt%201-069.jpg

http://panzerfaust.sslpowered.com/pl...rt%201-070.jpg

This time- I used stretched sprue as a hinge pin.
http://panzerfaust.sslpowered.com/pl...rt%201-071.jpg

http://panzerfaust.sslpowered.com/pl...rt%201-072.jpg

A pre roll on a larger diameter brass rod. You can see the very spring and hard to cut kit wire in the for ground. See the dent? This stuff is useless- Voyager needs to give their head a shake and provide something more useful!
http://panzerfaust.sslpowered.com/pl...rt%201-073.jpg

Cutting a piece off some stretched sprue.
http://panzerfaust.sslpowered.com/pl...rt%201-074.jpg

The sprue pins in place.
http://panzerfaust.sslpowered.com/pl...rt%201-075.jpg

Using the hot soldering gun to melt back the excess ends bit to for a rivet which retains the pin in place within the two opposing hinge parts.
http://panzerfaust.sslpowered.com/pl...rt%201-076.jpg

Here I am doing a better job with some incense...
http://panzerfaust.sslpowered.com/pl...rt%201-077.jpg

Okay- a working door, fragile but operational.
http://panzerfaust.sslpowered.com/pl...rt%201-078.jpg

A heat sink clipped to the door. This was done so I could add the part that represents the hook part of the clasp mechanism without melting the plastic pins.

awesome james! simply awesome and very helpful! thanks for this detailed explanation! :thumb:

Another ecsellent SBS and very helpfully for all ! Great topic for this sunday.

Positioning the tiny piece by hand onto some flux.
http://panzerfaust.sslpowered.com/pl...rt%201-080.jpg

http://panzerfaust.sslpowered.com/pl...rt%201-081.jpg

http://panzerfaust.sslpowered.com/pl...rt%201-082.jpg

here you can see the clasp part also inn place and the plastic hinge pin being introduced.
http://panzerfaust.sslpowered.com/pl...rt%201-083.jpg

http://panzerfaust.sslpowered.com/pl...rt%201-084.jpg

Here I have started another box -this time, separating the doors right off the bat.
https://panzerfaust.sslpowered.com/p...art%201-08.jpg

Box soldered up.
http://panzerfaust.sslpowered.com/pl...rt%201-086.jpg

This time I'm going to use some ABER hinge parts- far superior in design and practical strength. Also I bought some thin brass rod from LionRoar. for the pins.
https://panzerfaust.sslpowered.com/p...rt%201-087.jpg

Also I am trying a tool from Griffon that is very useful in forming the hinge parts.
http://panzerfaust.sslpowered.com/pl...rt%201-088.jpg

http://panzerfaust.sslpowered.com/pl...rt%201-090.jpg

http://panzerfaust.sslpowered.com/pl...rt%201-091.jpg

One way is to use tweezers- but there are different ways to get this done- even just your fingers.
