Correct, he's just testing the turbine with air. The real thing will use steam (in theory)

I heard that this system buckles under load. Don't know how true that is

Thanks for watching graham. Yes! That is exactly what happend, struggled to get the boots off it was packed in so tight lol. And thank i was surprised how good they turned out myself, that was the practice log i did the 14ft length on sunday turned out great and more than paid for the saw with cost of timber currently :)

@@cringleengineering7688 Well done splendid.

Hi Did you make the steam turbine for your project ??

Standardising improved efficency, i can use bigger if i want but i realy dont like humping the big flasks about.

many would disagree!

No, its a simple impuls engine, please see the next video for details of the rotor.

@@cringleengineering7688 Thanks

Thank you for watching

@@cringleengineering7688 no problem, if you can give more specifics like weight, or 1. list the machines needed by name 2. Show how to engineer/make the plastic parts you use to make the molds, 3. Specifications for how much sand to oil I would highly appreciate it. I desire to make all of my own parts.

Thank you, the rotor is an interesting bit to machine. The bearings are ball bearings and stainless steal, They last pretty well if the rotor is balanced, i also tried the high performance ceramic bearings and there much better but not neccessery at all.

Thanks for the feed back Todd, il reposition the tag. Ive still a lot to learn about editing, was considering adding narative but i think the subject explains enougth, also considering adding music but that seams contraversal too. what do you think about speeding up some of the machining shots? I see a lot do that but i also think it helps to show feeds and speeds for begineers to machining that my models are popular with.

@@cringleengineering7688 Thanks for your reply. I don't think you'd need to add narrative as long as it's clear what you're doing, and if you add on-screen text when that would be helpful. If you do use narration, you ought to do it "voice over" instead of "live," and you should use a well-edited and rehearsed script. Regarding the speeds-and-feeds issue, you could show machining at normal speed for several seconds and then speed up to 4X or higher speed before dropping back to normal near the end of that machining operation. I don't usually enjoy background music. In the States, at least, virtually no shopping or restaurant experience is free of annoying, distracting, loud, obnoxious, and mostly-juvenile (but sometimes geriatric) pop music. American business managers seem to think people are incapable of carrying on in public without an accompanying sound track. More likely they are in thrall to the conventional wisdom that forced music makes people buy more. When I feel like it, I listen to my own choice of music, and I mostly resent having other-people's music shoved up my #%@.

Bronze was used for this mold

OK thank you and then your casting procedure is good for soft metals cause I don't think it would work for cast-iron cast iron is like a weird metal to work with it's finicky if you ever have a chance of making a video with the cast iron I would love to see it how it turns out thank you for replying and all the best luck to you

@@gilberttwaterfield6389 thanks, i can do cast iron with the same setup, and it gives a realy nice finish, but it realy burns out crucibles and destroys my oil sand in no time so i prefer to use bronze.

Yeah I know the crucible is the issue for all cast iron I think a 15 or 20 max pour after that you're a crucible it is very weak also it shrinks it to lose his height and a good crucible is not cheap

Good luck with it, please let me know how that works out for you👍

This is petrobond sand, 'mansbond' is the make.
