4thtry's 2026 InDIYana theme project - Divide and Conquer

Got up to 70F today. I was able to bondo the bottoms and wheel/caster assemblies, then sand everything smooth. They are almost ready for the first coat of primer. But that will have to wait, as the temperature is expected to drop by 25 degrees tomorrow, then fall even further. Might even get some snow showers mixed in later this week.

Got up to 67F today, so I masked off and shot 3 coats of primer on all the needed parts. Since the weather forecast is not looking good for the next few days, I’ll use that time to let the primer dry. Then I can fill any imperfections with glazing putty, re-sand, re-mask and wait for another good day to shoot the base coats.

Another nice day (64F), so I sprayed 3 coats of burgundy on the bass bin edges. This color is an exact match to the burgundy on the RD40 cab baffles. Should look nice when I bolt them all together.

I had a very difficult time spray painting the caster assembly with primer. It was not very stable and would tip over easily. Hanging it on a hook or coat hanger didn’t work either. Not steady enough. So this time around I built a small stand to hold it steady. Worked like a charm.

Nice! Should look really good together.

Final assembly/wiring underway. Won’t be long now; can’t wait to give them a listen.

I spy some Menard’s fiberglass ceiling tiles used for damping :wink:

Yup. 1/2" thick Armstrong Pebble fiberglass 2x4 ceiling tiles. My local Menards always breaks open a 12 pack and sells them individually for about $7 each.

All done and ready to roll.

Oh, I thought you were color matching the tops and bases.

Initially, when I looked at the color match in person under indoor lighting, the color match between the bass bins and RD 40 cabs appeared to be perfect. But then, when I rendered the photos in Adobe Lightroom, the color tones came out different on the computer monitor. Kind of like when you take a picture under fluorescent lighting. It will look OK to the human eye in person, but when you take a picture, the software reproduces the scene, on your monitor, with a green cast. This is because the human eye automatically corrects the green cast of a live scene, but does not correct it when you look at a flat, two dimensional picture (or screen).

So now, after having taken pictures and studied the screen shots, when I look at the speakers in person, I can clearly see the color tone difference between the bass bins and the RD40 cabs. My mind no longer color corrects the live scene.

This is probably a form of confirmation bias. Now that the computer screenshot has told my mind that the bass bins have a slight redish tone compared to the slight yellowish tone of the RD40 cabs, my mind, in turn, instead of automatically color correcting the difference, actually sees the underlying color cast. :thinking:

Interesting, I have noticed that with taking pics of things and not really capturing the tones I see.

Your bass bins have a Tron thing going on :smiling_face_with_sunglasses:

Having seen the Plantanics, I would not have called that color burgundy; maybe dark red or even dark red orange, but not burgundy. Burgundy always ends up more pink in color than I think it should be.

The Plan-Tanics were a custom mix of red and black, not an off-the-shelf burgundy color from Rustoleum. I thought that they looked like burgundy, but I think you are correct. Maybe I’ll sand them down after Indy and give them a custom re-spray. I just have to remember how much black I mixed with the red when I did this 12 years ago. :thinking:
