Estes Plasma Probe Build Part 5 Prepping Plastic

The plastic wall on the nose cone was uneven.
So much so that the lip overhangs the body tube more on one side.

This will take some careful sanding to get it even.
There are some molding divots. Around the edge is a slight raised lip.

Take a moment and sand the small ring off the nose cone tip.


There is a molding seam on both sides of the adapter.
This recess line got a bead of medium CA.
After it dried the CA was sanded to surface. First with 220 and then 400 grit.

  1. Wow, I'm not there yet in my build, but my nose cone is uneven as well. And OH YEA, it hangs over more than you would like. If you ran your thumb with the nail down, it would stop it from passing over. That is how much it hangs out. Fortunately that is where a defect is and will give me some leeway on sanding it.

    1. I remember the nose wall thickness not being consistent. It took a bit of sanding to get it closer to the body tube wall thickness.

  2. Yup, on closer inspection - same defect.

    I guess we should be glad they gave us the room to sand that out...
