the 3D printed parting planes are going to be an amazing help with some of the parts that have a bunch of curves.. way nicer than trying to make those by hand. Even the brackets to hold the stuff helps a bunch, the contoured stuff is was just me wanting to see how well it would actually work.

I wish I had a fraction of the design skills it takes to attempt something like this. Truly impressive.

Photo dumps are nice
The printed parting board idea is going to save me some hair.

we all start somewhere. I’ve been self teaching myself solidworks for almost 15 years now, doing something like this even 10 years ago.

there are a bunch of solid model projects i have done in cad that will likely never be built just because i wanted to use them as learning tools.

I started doing some bodywork on my starship, so i did some on the T38 nose where i printed the correction pieces previously. After filling and sanding it, i was still not happy with the look of the nose. It still had “chipmunk cheeks” under the windscreen and the nose infront of the windscreen still looked off.
After help from friends sending me pictures and telling me to bite the bullet and just redraw and repring the nose, i decided that was really the only option to fix the nose.

*seems there is an issue with uploading photos, so i’ll try again later.

Here are a couple more pics, somewhat head-on. Not to muddy the waters... :-/
An A model, at Pima air museum (Tucson).




No - it wasn't me that bent the probe!...

I bet that probe gives some reliable readings.. hahaha


Don't worry about making the water more muddy, it couldn't get any worse. haha. I was pretty sure the nose was a bit to squared off, i still have a bit of refining to do. I'm printing off a small portion of it now to get a physical sample to look at.

I did some work in Solidworks on the nose gear assembly to get it positioned within the nose. Im planning on using Electron gear and a 95* nose unit just works, with some odd mounting angles. I need to verify the nose gear door dimensions as it appears it may be a weee bit short.







I also 3D printed a main wheel and a mold for a main tire. I used some leftover material from my Starship project to make a tire. Its 90% there, it just needs a few small adjustments.

I'm sure the probe would work well - just make sure you're turning to the right...

After a countless number of changes to the nose of the Cad model and printing it 4 times before finally getting one i was happy with, some progress is being made.

Couple photo’s of the cad model evaluation.





Here are a few photos of the latest nose print. Its as close as i can get if i believe, plus im tired printing these things. Lol








I also started working on the CAD files for all of the access hatch’s for the fuselage detailing. Im planning on cutting all of these on my vinyl cutter. The round dots are the locations for screw holes to be drilled.

the new printed nose has been getting some body work to blend it into the main fuselage. Most of this was concentrated between the canopy and the main engine hatch. All that body work is now done and the Duratec polyester primer has arrived. I am hoping to get the primer sprayed tomorrow or saturday so detailing can begin soon.

Glad to see some work on the T38. I like the new nose. Sanding filling sanding filling sanding did I mention sanding and filling. That is tedious part of building for sure. Looking great!!!!

I got most all of the fuselage hatch details drawn in cad and then cut from vinyl. I tried to draw large sections of hatches in batches to keep the physical relations between them together. This mean almost 18’ of vinyl to be cut.

Here is a group of panels between the horizontal stab. There are panel line pieces around the perimeter than will be used for the typical tape and paint panel lines, the inside of the panels are also there to act as drill templates for the majority of the 2200 screws in the fuselage.
