Hi Eric (@eb801): I just realized that I kept dropping a decimal when we were talking about 3D printing the other day. The time to print each layer is 3.0 to 4.0 seconds, not 30-40 seconds. It would really take a long time if it took 40 seconds per layer.

I had some minor success today printing small parts for the model. The parts have been painted and added to the cockpit. I am still working on getting a good print for the seats, but I am getting closer to having something usable. I also want to print some radios and a tank for the hydraulic fluid, both of which are visible in the cockpit. Cheers everyone.
4 attached images. Click to enlarge.
1. Throttles painted and installed. The large knob is supposed to be black, but it would be invisible, so I painted it gray. Still not great.
1. Painted the large knob on the throttles white to make it more visible.
1. Assembled rudder pedal linkage and rudder pedals.
1. Rudder pedals added to the cockpit. The troughs are a little wider than the pedals. If I had planned ahead, I could have moved the troughs closer together.

2. Rear troughs accidentally worked out better.

Tat cockpit is looking good @gblair.

Thanks, Tom (@tcinla). I am using the model as a canvas to try out these 3D printed parts.

Looking real good!

Looks absolutely fine, George @gblair
Good choice to paint that knob white.

The cockpit looks superb, my friend @gblair!

Thanks, John (j-healy), John (@johnb), and Spiros (@fiveten). I think things are moving in the right direction now.

The name of the game today is finding the right size seat. I have been printing several seats, one of which is from the T-6. I found what I thought was the right-sized seat and then went about trying to get a reliably good print. I solved the reliability problem, but then I discovered that the seat was too small. The measurements of the bottom of the seat match the bottom of the kit seat, so I assumed the back of the seat would be OK. When I put Freddy (my crash test dummy from the kit) into the resin seat, the back only came up to a point below his shoulder blades. That was really too short. So I have been scaling the 3D print of the seat to keep the seat reasonable, but have a seat back that would work. The scaling works on a percentage of the initial file, so I was working with scaling from 6% of the original print to 10% of the original print. I finally settled on a 9% scaling of the original file, and I have 2 good prints done. Now all I need to do is paint the seats and attach the seat belts without destroying the seats. We will do that tomorrow. Cheers.

1. What a mess! This is why I lose stuff. :o)
1. Various size trials for seats. The difference in scaling from the large one to the small one is only 3%.
1. These are seats I printed for an F7F. Only 3% difference in scaling.
1. This is Freddy, my crash-test dummy that I am using to check the seat size. It looks like he is still on the phone.
1. His bottom fits fine, but the seat back is obviously too low.

Looks like you finally found the correct dimensions, George @gblair
Will look great inside the interior.
Spiros Pendedekas said 1 year, 2 months ago:

Great that you found the correct scaling, my friend @gblair! Looking forward to see the seats completed!
Tom Cleaver said 1 year, 2 months ago:

Hey @gblair - what would it cost to get a set of those seats to use in my T-6?
John Healy said 1 year, 2 months ago:

Those seats are really cool, George.

Hi John (@johnb), Spiros (@fiveten), Tom (@tcinla), and John (@j-healy):

I have officially given up on the resin seats. They look great, but by the time you reduce the print size by 93%, the entire structure is so fragile that it is impossible to use. I got some good prints, but many of them broke when I removed the supports. Only one seat survived both removal of the supports and assembly, and I tried supergluing some plastic to the seat to keep it in one piece. It broke when I tried to add the seatbelts. I may try again sometime in the future, but for now I want to get this kit moving forward.
1. This is the last seat I tried. The plastic support I glued to the seat is clearly visible through the very thin resin. The seat shattered when the seat belt touched it.
My plan is to modify the kit's forward seat and scratchbuild the rear seat. I got the forward seat done and got most of the rear seat done. After spending the last week fooling around with printed seats, it felt good to finally get something done.
1. Modified kit seat, mostly done.
1. Getting started on the rear seat with plastic sheet and half-round tube.
1. Rear seat moving along nicely. I cut the yellow piece from the kit seat which I will glue to the bottom of the new seat to get the correct height.
The SNJ-4 had a tall antenna mast in front of the windscreen that wasn't present on the later versions. Although this kit is for the T-6G which does not have the tall mast, I was pleasantly surprised to find this mast in the kit. Apparently the armed version that you can also build from this kit had the tall mast. The kit has two forward fuselage sections, one for the trainer version and one for the armed version. The section for the armed version has a hole for the antenna mast. It was a simple matter to transfer the location of the hole for the antenna mast from the armed section to the trainer section.
1. Nose section for the armed version along with the hole for the antenna mast.
1. This is the top section for the trainer nose, along with the location for the antenna mast.
1. Ancient kit decals used for the prop.
It was grandparent day at my granddaughter's pre-school, so that is all that I got done today. More tomorrow. Cheers everyone.

A wise decision to move forward, my friend @gblair taken at the right time. Excellent looks so far!
A grandparents' day is always an awesome day, I am sure you had a super time!
