Greetings all,

I'm looking for something that has proven to last indefinitetly inside a rotary engine. It will need to be built up about 3/8"-1/2" where I'm using it. I was looking at High-temp Lab-Metal, but I'm told it's a real pain to sand. Any suggestions will be greatly appreciated.



Thanks. https://www.nopistons.com/forums/pub...DIR#>/cool.png

anything... jbweld sucks, use a welder.

Devcon Liquid Steel "B", mix the complete contents of both cans and dont worry about the waste

Thanks for the advice guys.https://www.nopistons.com/forums/pub...#>/biggrin.png

I wish I could weld it(havn't completely given up brazing or soldering), but it's in such an awkward place it would take forever and a day to grind and then hand sand it to the desired profile.



I checked out Devcon's site and found Plastic Steel® Liquid (B). Is that what you were refering to banzai?

It looks very promissing, although, the tech sheet for it does say it shouldn't be feathered. What has been your experiance?



I'm still open to more suggestions, so anyone else should feel free to chime in if they feel like it.





Thanks.

What EXACTLY are you trying to do?

Well...

I am going to do something seemingly crazzy/unconventional with it. I'd rather not say exactly because:



1. I'm not prepared to prove what I'm going to try because my knowledge in the matter is very limited. With time, testing, and furthuring in my education, I will hopefully be able to do so then.



2. I'm sure it would be very controversial because it hasn't been tried before(that I know of), and goes against the common-knowledge of the performance oriented world.



3.In the end I might end up with a pile of scrap metal and a great deal of embarrassment from following some crazzy notions.



I'm very sorry if I come off as some kind of my-idea-is-so-special-it-has-to-be-kept-secret jerk. Please don't take it that way. We all have some ideas/projects that we just don't want to share openly for one reason or another.



Basically, what I'll be doing is applying the filler/epoxy to cast iron which has had the casting texture ground smooth. I need to build it up to 1/2", either in layers or all at once, depending on the filler/epoxy used. It will also need to be featherd so as to blend seemlesly. It will be exposed to oven temperatures(450 F) and then slightly above average engine temperatures for the rest of its life. If the filler/epoxy were to ever come loose, the engine would probably be severely damaged or suffer faillure.



I've looked at quite a few types of metal fillers/epoxies that claim to do x, y, and z. But I want something that has been proven in the environment it will be used.https://www.nopistons.com/forums/pub...1047683473.gif

You are such a my-idea-is-so-special-it-has-to-be-kept-secret jerk!









Hey document it with pics and then share it with the class even if it blows up!

Lol.



Don't worry. I am documenting everything, that way, the people who may have to scrape up my remains will have some idea what I was attempting. https://www.nopistons.com/forums/pub...R#>/tongue.png



I do plan on posting when/if i get things back together. Its not going to be anything really outstanding. I'm trying to stay within my miniscule budget, and still be creative with a few things at the same time. I'm really attemping to make it as reliable as possible and more fuel efficient with a slight power gain.



At the moment, all progress has halted because i havn't found a suitable filler...

This forum is much more open minded, you would be surprised the beneficial ideas that get bounced around on something outrageous rather than people shooting the idea down to begin with





We've seen some crazy stuff here, that you wouldn't see posted anywhere else. It's all in the atmosphere. https://www.nopistons.com/forums/pub...IR#>/smile.png

Not only that, but there is also a rather good chance that whatever this brainstorm is has been done before, to whichever degree of success. If so, then one could have less wheel reinventing to do.
