So, I thought I was pretty experienced when it comes to machining, I naively thought that one day I could even build an engine that I could use to power my ultralight aircraft. I've learned a lot since then and am now significantly less arrogant but also significantly less confident that my ambition is realistic even if I am willing to work on it as a long-term goal.
Originally I thought the issue would be machining the accurate components which is no menial task in and of itself, it is one however that I felt with time and dedication I could overcome and have for the most part.
What I neglected in my foresight is the composition and pedigree of the engine material I would require. So my question, what is the correct grade of alluminium for this 'lofty' ambition, can it be sourced locally to avoid months of waiting and expensive shipping rates and will it hold its own for its application.
Regularly I use 6086 T6 alluminium for regular stuff cause it's easy to get where I live in Ireland. I'm not optimistic about this at all, My concerns are that I will not be able to source the material, or afford the right spec of alluminium to build an ultralight engine. Which as you can imagine needs to be somewhat reliable when you are 'x' amount of feet in the air.
Piston engines aren't great as it is for an aircraft but one made of unreliable or heavy material is just not a good idea. I feel I should be more concerned with the actual flight itself but I don't think I'll get to that point so if anyone can offer any advice that would be great. I know generally this forum is for the 'model' engine but I'm sure all of you have at least considered putting your engines into practical applications or have done so.
