painting pulse jet

[bastard squad]

iv found some very high temp paints that im considering buying so i can paint some of or maybe all of my jet...some are only up to 1500 deg and others are up to 5000 i think....how hot does the outside of a pulse jet get???

why would you want to do that?

Um, this might be more of what you're looking for, at least it works for me.

Stephen -

See Bill Hinote's 'Black Body Heat Rejection' thread about the advantages of making your jet pipe black -- basically, improved radiative cooling.

I've read several anodizing techniques, including Bruce's, and nowhere does anyone have any speckled designs. I have some MAG-LITE aluminum flashlights of red and blue and purple even but I haven't seen any speckled designs. I think speckling would be really neat stuff. Multi-colored patterns might be a real hot seller. Even a flashlight would be lots more fun if it had exotic color schemes instead of a single boring color.
Maybe some sort of Peter Max inspired color schemes would sell as well. Are manufacturers afraid of speckling do you think? If it's good enough for Easter Eggs it's good enough for pulsejets I say.

Something tells me you have not realised the unexpected things plain one-colour anodizing may have to surprise you when you think things are OK ;-)
But it's fun to anodize, thats for sure.
Sometimes it even looks nice too.

I'd like to see some failed results just for the patterns where the dye took in different depths of color and form. I was looking a box full of anodized items for rope, lots of pretty colors like jewels, still they were each a single color.

Makes you wonder if you played with the technique a bit, if you could tie dye it?

Wouldn't that be a laugh. A tie dyed (sic) pulsejet. Probably go over well with the people in California though. :) :)

Or perhaps something like this would make for an interesting tie-dyed Dynajet Grateful Deadhead.

And if you are going to tie-dye your engine or be seen with a psychedelic pulsejet, you're going to need socks.
