@Kwikvette here's some horrendous welding for you

This is how the exhaust manifold (exit port?) Came stock on the engine

Well there's not enough room in the shroudwork for the muffler to hang down, so I had to cut it up and resend it.



Making sure it's a square cut

Flipping it 180 and checking to make sure it's level with the engine

Welding cast iron is fucking rough preheated the shit out of both sides and the bead still came out stupid cold

But bossman is happy with it and said he couldn't do better so

 

maybe you’re building one

 

I'd wheel it

husky is just like "rip, I'll remember you bro"

 

Accurate lol

 

Refuse to watch the whole thing but why the fuck is everyone cheering? Usually it's a bad sign if something blows up on an inaugural flight

 

Last one I did just came in for a filter change. It's got 672hrs on it and isn't broken yet... although I was positive it would given the porosity

 

It was expected to blow up, it's the first of several experimental launches that are going to be part of the Artemis lunar mission. Largest rocket ever built, it was 50/50 expected to blow up on launch lol. So it was pretty successful that it got as far as it did

 

Fair enough

 

EGTs probably ain't that hot

 

I think our keypad keeps track of that, I'll look when I get to the point of firing this up.... if I ever get done building this thing lol

 

plus they probably have pretty long run cycles, right? Or do they do a lot of short run heat cycles

 

i recommend keeping EGTs above 1300F to eliminate soot build up

 

Depends on the job.. if they're hooking up a wall saw the thing will run for an 8hr day solid. If they handsaw with it they may only run it for an hr at a time

 

Looks like rats only got the two lines into throttle body from what I could see when I checked at lunch.
They could've at least picked more convenient lines to replace.
Might as well clean the TB while I'm at it since things will be apart.
It's stored at my parents house so working will be interesting. Poor thing is on gravel under a big oak that's dropped so much shit on it, it's crazy. Really wishing I had a garage right about now.

 

That's a good looking weld honestly, especially for cast.

I fucking hated cast and would do what I can to get a good preheat using oxyfuel.

I miss oxyfuel...

 

hopefully not tree sap, that stuff is a bitch to get off

 

Get an oxy/propane setup... bonus you can use the large propane tank for grilling... well until california outlaws barbecues

 

alcohol gets it right off

 

Like those outdoor heater/grill types?

Those are a hell of a lot cheaper for sure; sir you gave me an idea.
