Detailing has begun

i started off with the canopy and the windscreen. I use varying widths of masking tape for any parallel panel lines. I use a 4mm vinyl masking tape for the outlines of the clear portions. Panel lines themselves are either 1/32” or 1/16” chart pak tape. I also marked canopy and windscreen frames for all of the drill positions for the screws.

i also wanted to see how the vinyl cut hatches would do, so i put the ones on the top of the fuselage behind the cooling vents on

i also started drawing the panel line locations on the nose section.

I got the bottom fuselage details put in place. The ones that are left are the ones that transition to the fuselage sides as well. There are right around 700 screws on the botom of the fuselage.

Continued on today. I got all of the panels on the right side of the fuselage installed minus two. There’s about a dozen panels in total left to do. I also have about a dozen panel lines to add. There are also 3 pairs of overlapping panels that need added.


Total screw count: 1200 and counting

Thomas,

Some amazing progress recently! Looking forward to seeing all the details completed and the first pull from the mold. Would still love to have one if you decide to do a limited run of kits.

Today progress. I got all of the panels done, the vinyl spine doubler installed, the overlapping windscreen frame done and started the flite metaling of the exhaust area and its rivets.

Todays progress was finishing the flite metal and riveted lower panel of the exhaust. I also got the surface details that as more prominent put in place. This is mostly the panels directly over the wing and a few screw lines above the horizontal stab. Everything else fastener wise on the fuselage is filled over during painting and largely invisible.

i also changed the panel line piece for the lower engine access door hinges to a version that is more like the real ones.

Last time i was home i got the remaining surface details put on. When i got home yesterday, some of my chartpak tape had arrived so i got the last of the panel line tapes put on and then primed over the entire fuselage with a few good heavy coats of primer, especially where the panel line tapes were. Once this has dryed overnight, i’ll get to sanding all of the texture into the proper places of the plug.

all 1,662 screws have been drilled and countersunk as well.

Well…. the T38 detailing has progressed. The skin texture “waves” around the rear of the fuselage has been sanded in. I also got 1000 of the screws put in and picked all of the rivets and panel lines out.

My hands are now killing me, so tomorrow may be a recoup day for the hands after all those screws.

Amazing work Thomas - makes me want to start a new project.

What are you using for the gray paint over the Duratec? Will it polish up to a high-gloss finish for molding?

Thanks Paul.

its just Rustoleum automotive rattle can primer. Used the same stuff on the tail and it made a nice mold surface once waxed. This stuff sprayed on really nicely, so it has a nice surface as it is, i probly wont even do much sanding, if any, just go straight to the mold release wax.


got any idea’s for the next project?

Main hatch and canopy parting plane cad modeling is done. I have decided go do a “flared” parting plane for these. Reason being is i am hoping these flared planes will make it simpler by having each hatch be a 2 part mold. This will make trimming the layups at the corners easier and allow a more consistent and better quality corner. That is the hope atleast.

The fuselage detailing is complete with the fuselage spine texture now sanded in. The 3d printed parting planes will be done today. When i get back home next, i’ll finish drawing the remainder of the fuselage parting planes so they can be cut on the laser.

if all goes to plan, the two hatches and nose will be ready to mold by the end of the year.

There has been substantial progress made the past few weeks.

The hatches and nose were parting planed off. The hatches getting 3D printed ones and the nose a combination of printed and laser cut white board material ones.












The hatch tops were then molded.











The hatch bottoms got a similar 3d printing parting planes. These parting plans are placed on the trim edge of the hatch flanges an will hopefully make it easier to trim the flanges consistently.







Next up, the fuselage top was molded. This was a nine hour layup from start to finish.





Two days later, it got rolled over, pva’d and then the bottom was molded.








currently ive got some fuel tank molds printing so i can get those prepped and ready for layups when the time comes.

all of the main fuselage parting planes are also all laser cut or printed, so i will start prepping the fuselage for molding soon.
Vacation begins mid Feb. so I am currently on schedule to have all of the major components of the airframe molded by the end of Feb. the only items that will be left to do are gear door and speed brake molds.
