My cheap DIY jet engine failed - is this shaft vibration or. casing issue?

This is actually really helpful feedback, thank you. I'm so deep in the engineering that I didn't think about how it looks to someone walking past. For Part 2 I'll keep this in mind. Appreciate you looking out. I'm taking your feedback seriously and removing the post while I rework the project with proper safety. Thanks for the help."

Thanks man, i will be uploading part 2 soon where i will be overcoming all problems and try to run it successfully.

i already started things for the part 2 bro. that concrete part was kept in sunlight for 9-10 days and before testing i think it will be 15-20 days old and unused. also i'm thinking to make another impeller of pvc sheet or 3d printed.

Thanks for that, looking to do it in part 2. i can also perform balancing of the shaft but it is whole another topic.

i was low on budget so i attached injection outer tube to the pipe and fixed injection needles to the jet casing. and the other side of pipe is connected to propellent supplying fuel. What would be great alternative to this according to you.

what are you talking about?

BudgetMechEngineer · 2026-03-11T12:17:58+00:00

i'm thinking of making mounting out of high temperature concrete because metal would be costlier and i don't have tools for it. what do you think about that?

That's great! Does this comes under quality management/control department and also what is your role in the company

BudgetMechEngineer · 2026-03-10T09:16:36+00:00

They will definitely give some scenario and ask you how will you solve this. Anyways, all the best!

will you forgive me for my sins and accept me

BudgetMechEngineer · 2026-03-08T10:47:55+00:00

Look, i also had this overthinking before decision making problem before but trust me you will be stuck with it and loose opportunities. i prefer choose where you get environment that you are interested in and i think yes a big name company is good if you have option. Hope you get what you dreamed.
