I see this thread ticked over to page two, so I thought Id pop in and see what was up.

2 coats of rustoleum gloss white to the base this weekend. It was unbelievable how much paint this old fiberglass soaked up! I used 3/4 gallon on the base for the 2 coats.

Still have to do the glass work on the dome and shutters. Time is at a premium right now. Hopefully it stays warm over the next couple of weeks so I can get the dome finished!

Thanks for thinking of me!

Yep... I'll have them up tomorrow. I also scuffed up the inside of the base with 60 grit for applying 2 coats flat black. There was also a bonding seam that I needed to cut out. I still have to fill what's left - sharp edges that I don't care to find in pitch black / minimal lighting while in there.

Photo of base interior and tank seam - this seam is essentially where the two halves of the tank merged. The lower section of the base (the bottom of the four segments between reinforcement rings) was fused together with a fiberglass bond. It's the only part that isn't perfectly smooth on the outside. It isn't bad, just not mold smooth like the rest. As indicated yesterday, I cut the lip off from the bond (on the inside), and will fill the spot to make it smooth. I'm not too worried about the looks, as the wrest of the inside is uneven (smooth but uneven) - I'm shooting more for safety (no place to catch skin on). I'd still like to consider some type of fabric inside once the dome is on and everything is in-place for noise reduction.

That's my son Jack. Great kid!!! Hopefully will turn an eye toward some form of science or engineering someday. He's certainly getting a back-yard education in them!

I managed to get a little work done to the OB over the weekend, even with a 21 mile long run, and a 21 mile bike ride...

Got one coat of flat black to the interior of the base...

The line that isn't painted in the above photo is the seam that still needs to be ground/filled.

Here's the start of my fiberglass work... Glassing IS easy... And not. None the less, it's getting there. Need more resin and chop...

These photos are perplexing... I've used corel photopaint to edit them down to a smaller file size and renamed them - when I did that, the photos seemed to lose a lot of detail. When I don't change the name, more detail... Go figure!

If you are working with jpeg files, every time you save the file you lose detail, that's why renaming causes the problem.

The project is looking great!

Looks to me like you're using some kind of low bit depth format for your images. You can see this in the banding that shows up in slowly changing colors. Look at the image with your son in it above and you can see the banding very distinctly on the fiberglass tank. This low bit depth will cause the images to lose detail in some of the areas.

Make sure you're using 8 bits per channel. This is sometimes referred to as 24-bit images, and sometimes 32-bit. Not sure what Corel Draw calls it. But if you use 8-bits per channel and then save it as a jpg file, you should be fine.
