Wargames and Railroads: Sledgehammer Project; Preparation Pt XVIII

Trying to move forward from the rather disastrous UE build I pulled out the Sledgehammer BFG itself and resolved to at least get the sub assemblies together so I could start planning how the extra detail parts are going to be added.

I took a bunch of assembly shots figuring that it might help others that are working on this little beauty at some point. First thing to remember is that I did a lot of filing and filling before this. Since some of the filling required is for gaps and injection marks that are very visible I would really recommend going through the filing/filling exercise before you begin any of the assembly.

Starting with the gun carriage, this is pretty straight forward.

glued up and ready to go.

I have opted to go with the tracks from Victoria Miniatures, rather than the kit supplied wheels. Again these are pretty straight forward and are conveniently labeled left and right on the back side.

Some cleanup is required. The mold line goes right down the middle of the tracks.

And of course on the bottom you will have to deal with the resin blocks.

Ran into some issues with the left tread. Look at the bottom enter and you can see a whole link looks like its missing. This casting is probably bad enough that I could get a replacement, but I'm not going to bother with that, especially since I have had the tracks for at least 4 months now. Remember to check your resin parts right away in case this happens to you.

From the bottom, its evident that this is definitely a miscast, the mold was filled enough or may have slipped slightly during the casting process.

The ladder attached quite nicely, although I did have to shorten the locater pins on the ladder a bit.

The tracks all ready the extra detailing that will come later.

Back to the carriage the wheel/track axel. This is a single piece and because the pins for the wheels and/or tracks are so evenly spaced its easy to put on backwards. The center axle mounts into the tabs underneath the carriage, the other axle goes to the front of the carriage.

Like this (looking from the bottom where the tabs are located)

This is how it looks from the top

In theory, all of this should just slip together now. Remember when you need to glue the tracks in place you will have to use super glue. The tracks are resin the gun carriage is, essentially, polystyrene (which means you should be using plastic model glue, not super glue for most of the construction).

Whew, it all fits together quite nicely. Note that I have not glued the tracks on at this point.

So directly above the axles is this stupid little gear, it drops into place and then that large plate is glue over it. It spins very nicely. In the context of the model its completely useless, so don't worry about getting glue on it, no one will ever know. In real life its part of the gun elevation system.

Here I'm starting on the barrel assembly

The hydraulics to the recoil. Note that the end cap needs a fair amount of filing and filling and its very visible on top of the gun.

Getting it together, its a very large gun

Putting together the breech block. the first piece is already glued in place to the barrel. The breech block needs to be attached to the door and since I'm going to have the door open, I'll need to fill in that very large hole in it.

The front side of the breech block. I may scrape off the molded on handle, its very soft looking.

I think these would be counterweights and what others have called "the Fin" for lack of a better term (and I'm sure there is one) I'll go with that. You will note that the curve on the Fin is smooth if this was a real artillery piece this would be geared, its part of the gun elevation system and would engage with the small gear from a couple of steps ago. I'll be modifing this piece to have a geared edge so that it at least looks right, although you may not be able to see it when the build is done.

Getting ready to do a little gluing. At this point just the counterweights since I need to work on the Fin.

These are the cable reels with cable molded on.

And the reels glued in place.

The components for the crane

You can glue this piece but I didn't. I wanted a little bit of swing to it since the diorama will feature the gun being loaded.

All glued up.

The upper piece for the shell carrier is glued to the the ring. I have not glued the base plate on yet, I'm not sure what position I will need to have it in so I can make it swivel appropriately.

Mounting up the gun. Again, this has not been glued into place yet as it will be receiving a bit of extra detail.

Test fitting the platforms. Again no glue, my intent is to use the supports underneath the three planks and replace it with a metal walkway on both sides.
