Thanks! Really missed working on this the past few weeks. I need to keep making regular progress if I am going to get this done before Halloween.

Don't feel too bad, I squished mine too. But it bends apart easy enough. :) Would not have been a problem except for the fact that it was causing a wobble when spinning the knob.

The Gun Mount backplate has been bothering me. The inside shell was not level in this spot and was causing an issue with the plate alignment. I mixed up some green Milliput to smooth this out. Once it cured, I epoxied the plate and it aligned perfectly. I will be reinforcing a few other areas of the shell in the next few days.

The Injectors were not aligning well with the bottom of the Power Cell. With the addition of the L-bracket connected to the pack, this probably would have been fine but I wanted a nice connection here so I mixed up some more green Milliput.

Image

While I was at it, I hit the Attenuator Discs to smooth the rivets into the shell. I was at this point I realized I would rather use black Milliput instead of the green, so I put a hold on the effort and placed an Amazon Prime order.

It's cool to see what you're doing with the EDA discs. I want to do some rivets on mine but I'm curious as to how they'll turn out. Looking forward to seeing yours.

While I wait for the black Milliput to arrive, I had an opportunity to reinforce the mounting for the Booster Tube. I ordered the aluminum tube from OnlineMetals along with a smaller one to use with the TC thrower. I cut it to size and it installed easily with two tapped bolts through the back... but it wobbled slightly. To correct this, I created a plug using (2) 2x4 wooden blocks glued together then roughly shaped and sanded into a cylinder.

Image
Image
Image


After the epoxy cured, I trimmed off the exposed plug and sanded until even with the tube.

Image


A 1/4-inch lag screw through a new hole in the shell tightened up the tube nicely. No more wobble!

The black Milliput arrived and I reinforced a few thin areas inside the shell. Milliput is easy to work with and is tough stuff once cured. This may not be the proper way to strengthen the thin spots, but it was easy and I hope it will be effective. Will use the Milliput again to even out the Power Cell window and to fix a few cosmetic areas on the outside.


Around the Tube Clamp opening and L-brackets mount points...

Image
Image


The Synchronous Generator where the tubes enter was very thin...

Image


Additional reinforcement for the Injector mount under the Power Cell...

I have been very happy with the GBFans shell. It's a great piece and I highly recommend it. One cosmetic issue has been bothering me, however. The raised "fins" around the Power Cell, Crank Generator and Gun Mount all have a slight but noticeable concave dip. To fix this to my satisfaction, something which is completely unnecessary and me just being... well, just being me I suppose... I needed to build a few guides that will shape a Milliput topcoat. I fashioned these from the tree known as popsicle stick. Each is double thick and then sanded down to size...

Image


I wrapped & positioned the guides using painters tape so I could easily remove before the Milliput set...

Image
Image


I worked the Milliput until it was reasonably smooth & flat. One trick with Milliput, a little water and a flat tool really help with final shaping. Another helpful tool... patience...

Image


To remove the guides, a razor knife dipped in water easily breaks the bond. Once this cures overnight, will follow-up with sanding...

Thanks. I'm following a lot of others original ideas but trying to be open minded at each step. Hope I don't screw it all up!

After the Milliput cured, I cleaned it up with some sandpaper. As opposed to some other builds, I'm going with rough grit sandpaper on some areas. Hoping to simulate woodgrain but unsure if it will show through the paint. I'm much happier with the "fins" now. The concave is much less evident and the Gun Mount will now sit flush for a secure fit.

Looks good! Where were you when I was at this stage! Haha! I would have done that too, my fins chipped out a lot on the edges and had to do a lot of repair work to it.

Thanks, Jay. You are much younger and more energetic. I just can't keep up with the pace you and the other builders set!

The uneven thickness behind the Power Cell Window was another small issue needing some attention. The first step required another donation from the popsicle stick tree. I glued several together to get the desired thickness. After sanding down to the same size as the window, I soaked in water for a minute or so to prevent the Milliput from sticking during the moulding.

Image
Image
Image


Using the leftover block, I shaped a piece roughly as wide as the transparent blue acrylic. After working the Milliput into place, I used this block to ensure the acrylic would sit flush behind the window. Again, a few drops of water help smooth out the top finish of the Milliput.

In addition to the simulated woodgrain, I wanted to add a few details to shell to make it look more authentic. Not trying to replicate a specific pack, just include similar reference points.

One of those things is nail heads showing through putty on the "fins." To accomplish this, I cut down several small nails and drilled shallow holes in a few spots. Don't forget to add the faux countersink.

Image
Image
Image
Image


Mix up a small amount of epoxy and set those nails in place.

Image
Image
Image


And follow that up with a bit of black Milliput to simulate wood putty.

Thanks Phil. This is a fun stage in the build. Lots of opportunities to experiment & customize.
#4805784
While I was in the mood to experiment, I added some additional faux damage courtesy of flat and round files. Will be interesting to see how well this shows through the paint and weathering. Should know soon enough. Believe this shell is just about ready for priming and texturing. Hope I didn't forget anything important :-?

Thanks! I know what you mean about taking notes. If you find an efficient method, let me know cause I seem to lose track of most of the notes I took. I keep saying to myself, "now I know I saw someone do this thingy but can't find the damn post now that I need it!" ;)

PssdffJay wrote:What method are you going to use for the texture?
Still undecided on texture. Hammered seems hit-and-miss. I'm not sure I trust the durability of the ceiling texture, really just wall paste in a spray can. I have another idea I am going to test shortly but it's unproven.

And one more thread. http://www.gbfans.com/community/viewtop ... =2&t=36515 I know I've seen more builds with them and I'm smacking my forehead for forgetting to put them on mine.

Well hot damn. Never seen that before. Those are going on for sure. If for no other reason than to further delay my texture decision!

Also noticed something else I had not seen previously. A hole in the bottom of the PPD.

Big thanks to Jay for helping me out here by recommending that I drill the Cyclotron holes. First, I cleaned up the inside using a power sander to ensure the Cyclotron lenses would sit flush. For the holes, I wasn't sure of the accepted measurements and I ended up just drilling freestyle after drawing a few grid lines. Not perfect but I am pleased.

These are just under 1/8-inch. Do you think these look okay or should I go a tad larger?
