I'ts been 10 years since I started my last scratchbuild shell and I thought it would be a great anniversary to start my final build that I've been talking myself in and out of for the past several years. My previous shell is something I'm very proud of and grateful for but has a few quirks I wanted to re-adjust. I probably could of more or less just pulled a cast from my mold and hacked into it and made the adjustments necessary but I thought it would be more fun to just start from the ground up and document my progress as it might help some future scratchbuilders that are eager to start their own builds.

I've got some new measurements from MBurkit (Thank you) in addition to some previous ones I've had that might help fill in some gaps in the areas I more or less had to guess. I know Mack Factory is releasing a direct cast Sony Lobby Hero/Spengler shell that will put an end to all the measurement speculation but until then I thought it would be more fun and perhaps nostalgic to be like the old days and try to get as close as I can without having it on hand.

As for the materials I will be using .080 styrene for most of the structure and of course will be using .125 (1/8 inch) for the various ribs, cyclotron rings, and syncgen plates. Looking back in hindsight I can't believe I finished my first shell in roughly 2 months. This shell might take a little longer then that as I plan to be a lot more tedious with the measurements.

Of course I started with the powercell like my last build. This probably took me 7 hours plus to build, I thought I completely nailed it then I went back did some various double checking of measurements from different angles and I was off a hair....partially tore it down and rebuilt it to spec.

Here is the styrene workspace to start with. I usually start by measuring all my templates/faces out on some styrene. I always cut a tad more so I have material to work with in case I was off or undercut.
Image
Start gluing all my faces together and sand smooth. At this point I start dremeling with a sand drum all the curves and corners to match the screen used packs before I start placing on the ribs. I also do another check of measurements to make sure I'm good on all angles in case I'm not I could easily readjust.
Image
Starting measuring and sketching where the ribs will go. The sketch on the box is just a rough draft of where the ribs will go. As I'm putting each rib on I'm using my ruler to make sure each rib goes in its precise spot.
Image
Hours later were finished :cool:
Image
Image
All the angles and tapers are to spec and I'm happy with it!
Image

On a side note the powercell on the screen shells has a taper where the base of the power cell is wider then the front which causes this slight angle.
Image

Now were moving on to the crank gen. The crank gen is an absolute beast to build and probably one of the hardest parts of the shell to build especially when trying to match the screen used shells. There is so many uneven measurements, tapers, and wonkiness to it. So far I've slayed the beast and wounded it to my liking but it's still half way alive and need to further slay it to my liking. On to putting the finishing touches on it and getting all the corners rounded off, sculpted and smoothed out.

Thanks for looking and all comments are welcome!

Do you prefer styrene for mold reasons.
Thanks Q. I thought about it but really just wanted to keep the same material it's much easier and I don't want to run into adhesion issues with the wood vs styrene mix. It probably would have been fine but I could easily give a faux wood grain look to the styrene similar to how I did on my last shell.

Made some progress over the last couple weeks and thought I'd share some photos..

So of course we start with the base a lot of odd and wonky measurements going on this looks like the easy part but it took me a day or two to just get this far
Image
Image
Then of course I start to cut out all the ribs on a sheet of .125 Styrene. I overcut the ribs to make adjustments in case I don't place the the rib down right the extra excess makes it easier to snap off and readjust.
Image

I ran into an issue with the powercell which I thought I got perfectly right but I got a text from my buddy Burkit and he helped out and pointed out that the bottom powercell rib on the screen used packs doesn't enlarge towards the motherboard like seen in this picture
Image
Burkit shared a reference photo showing that the rib stays the same size all the way through. I was baffled for a day and it drove me crazy because I didn't understand what went wrong. After many hours I finally wrapped my mind around it and figured out the mystery and realized that on the screen used packs instead of the bottom plate of the powercell being square like I had it that it actually is angled with the bottom powercell rib so that it runs the same size all the way through like so
Image
Image
I made the adjustment and now it looks right. I looked on MacksFactory Idealized Hero Shell and he had the same artifact and that's probably because he used the HMS Production shell as reference.

I start taking a dremel tool and getting all the corners and crevices rounded off and looking like the screen used crank gen
Image
Had to make sure the top ribs are crooked like the screen used shell
Image

Add a fresh coat of filler primer and were done for now. I will definitely go back and add in all the faux woodgrain/nails marks/texture when I'm closer to being finish. This crankgen is much more accurate then my original and I'm extremely happy with it!

Were moving on to the gunmount now. Stay Tuned! All comments welcome.

Amazing to see this! Really brings back some memories and I´m going to be watching the progression on this shell for sure :)

Love the shapes of the generator, super nice job.

On the powercell i was wondering more or less recently if theres a second taper which is only on the fins about an inch or so away from the motherboard. In some pictures it looks like the fins on the side of the powercell get thinner from there towards the motherboard. I thought i would add this to my shell as well so i just wanted to point it out and ask if im seeing things or it looks so to anyone else too.

Good luck with the build, looking forward to see more!

So good to see you back Bjorn! Just seeing you post again is pure nostalgia for me and brings back memories of the good ol' days of the board. If it wasn't for you I'm sure none of us here would probably even know what styrene is :cool: . Your the OG master styrene builder. Newcomers out there take note Bigi71 is the man.

For the powercell ribs your absolutely right...it looks like the top 3 side ribs have a small taper going towards the motherboard. The fourth rib has a very small taper but barily noticeable. Looks like the artifact came from sanding or grinding down. This is a detail that I'll probably add last but good eye for noticing that! I don't think it's a detail that has been replicated at this point.
Image
Image
In this last photo it doesn't really look like much was grinded down...maybe half or quarter of 1/16th a inch I'm guessing.
Image
Thanks James and Burkit for the support and comments. More coming soon!

We are still rocking and rolling guys got another update I wanted to share. I moved on to the gunmount, EDA, and spacer. Here some pics of my progress.....

Image
I'm super proud of this EDA as it's much more accurate then my original. This was one area that always kind of bothered me on my original shell and I was glad I got to rework it and get it right! I added the proper curves and tapers this time around. 10 years ago I thought the left corner taper ran all the down but it doesn't on the screen used shells and it's pretty much like so.
Image
Image
This gunmount is also far more accurate then my original shell. I missed a couple angles on the mount box on my first go -round and was able to correct it this time.
Image
Image
Image
Built the corner above the gunmount. On my original shell I had the width of bevel much too narrow on the screen used packs the bevel is 3/8 and flares out to about 1/2 towards the gunmount and crankgen....Thanks Burkit for tip on this one my man!
Image
Image
Image
Started work on the cyclotron....I wanted to get this out of the way as it's probably the hardest part of building a pack. If I could get this out of the way it should be smoother sailing. I built the cyclotron much better this go around and thought I'd share what I got so far. The cyclotron on the screen used packs is roughly 2 inches high including the half inch frame around it. I added a channel around the edge so I could sculpt the rounded edge with putty and sand smooth.
Image
Image
Image

So that's where were at so far. I'm going to finish off this cyclotron the next coming days and get the cyclotron rings cut out then move on to the syncgen. All is going well! Thanks everyone for the support and as always any comments welcome.

Hello Abaka.......I'm still making progress and plan on finishing the shell sometime soon. I got a bit sidetracked with a few other projects as I'm preparing for Dallas Comic Con next month and I plan on giving the shell my undivided attention after that.

I have made some more progress since my last post and I started building the Syncgen and finishing up the cyclotron trying to get everything within the parameters of the Spengler Hero Shell outline someone was kind enough to send me. This is pretty much where I stand at the moment....
Image

I've posted a couple updates on my Youtube channel discussing a few areas that were reworked or problems I've encountered https://www.youtube.com/watch?v=zJOh2E1_wkM I'm so excited to get back to it and trying to recreate all the screen used details. I've got a few ideas and so far this is coming out so much better then my first shell.
