Re: Mike's Build Log
Wow that's a lot smaller than I thought! Looks great. Can't wait for the first run.

Re: Mike's Build Log
Man those look great Mike. Next gen manufacturing right there. Even though you've posted some dimension, I would have loved to see a banana for scale haha. When are you planning to take them for a spin?

Re: Mike's Build Log
Do you think the combustion chamber heat will contribute to the augmenter effectiveness? Let's make a poll: I say the augmenters will get it up to 5.5!

Re: Mike's Build Log
Wow that's a crazy design Mike! Should be really interesting to see this thing printed. Are the protruding round parts meant to affix the aforementioned augmenters?

Re: Workshop machinery
There's visible play, I have pretty much no tools for it and the tool holder is diy. I think there's a crack in the casting at the termination point of the lead screw.

Re: My first pulse jet!!!
Use 1mm stainless steel for engines that last a good while. You can also still weld 1mm steel pretty well. A slip roll is useful but by no means necessary! You can get really good results with a piece of round and later square pipe clamped in a good vice and a hammer. That's how I built most of my e...

Re: Lockwood Hiller Pulsejet *almost* running
Hi Comics, welcome to the forum! Nice build you have there. I don't think the straight pipe will be a problem. Looking at your video, I have one piece of advice, and this is the first time I've said this to anyone on this forum: I think you're using too much gas! Right at the beginning of your video...

Not with that attitudeMike Everman wrote: ↑Tue Dec 15, 2020 2:55 pmI had to quickly figure out the auto start fuel again, since at the shop we got rid of our air compressor and switched to a nitrogen tank for blow off, which doesn’t work so well for starting a pulsejet!
Good to see you back to fin-nicking with jets again!

Re: ScrapQueen's turbocharger jet
I tried to build one of these things before. I had a hot (non)start and burned up the turbine. The only advice I can give is: don't try starting too long or you risk overheating. Also, as a general rule: bigger turbo chargers are better suited than the little ones. On a side note: welds are really i...
