Let's just say that 3 rotor ain't the only semi pp around, namsayin'? :D Love the detail on the assembly, it makes me less scared to build (or rebuild, rather) a rotary for myself in the future!

cyanoacrylate will ruin the seal tension springs and plug oiling. super glue will break down when fuel hits it and can take with it some aluminum and wreak havoc. are you using ARS or Ianetti Ceramic seals ? 27:32 I hope you didnt get WD40A on those o-rings! WD-40 on o-rings will dry them out and eventually ruin them, especially if you do not put silicone grease

That dial test indicator is actually more accurate than a regular dial, those hash marks are half a thou and not a full thou.

@Rob Dahm are you balancing or lightening your rotors and rotating assembly? na 20g weight difference is quite big... I had my old school 13b bridgeport (GSL-SE block running NA) fully balanced and rotor weights matched , its standard practice in New Zealand when building motors.

When you're confident you'll make 1000+ HP with an engine built with worn parts because the main test is on whether adding strength to key points of the engine is the purpose of this project. I do really hope this three rotor gets the proper attention later down the road. If this mishmash of worn and slightly unbalanced parts makes 1000+ HP, imagine if it were a properly built engine. Also waiting for the C8 rotary Corvette.

I love watching your videos but everytime I watch your videos I just feel stupid and dumb because I know nothing about rotary Motors but it is also interesting a neat to learn a rotary motor actually seems like it's easier to work on than a piston motor

The product you're looking for to keep metal from rusting while in storage is Jet Lube 12/34, I sprayed a head for a 32L Cat that had to be flown to site and the bag it was is I sprayed with 12/34, the site tech guy called the shop, asking what the product was, because it was in pristine shape, also on a side note 12/34 has millions of uses, gun oil, lube to protect other greases from absorbing moistures.

Why didnt you make a metal frame for the oil pan, something that looks like a gasket but it sits on the oil pan lip between the bolts and the pan? That way theres consistent pressure and not just where the bolts are mated and it wont stretch the pans mating surface.

So out of sheer curiosity why don’t you use full thread bolts?
sutiikotaa Month ago
What if you machine bloks to keep the mid iron and first cylinders in and rotate it on the bench? Could make sure you are not crushing seals and wouldn't need to guys to put it together.
Ryan Month ago
Rob, when are you going to get with Tavarish and help him with his rotary?
Jesus Cales-Rodriguez
One thing I learned long ago is to never torque or remove tension bolts with the flywheel nut off. I hit the threads on there and ruined an e-shaft once.

Rob have you ever thought of using a 5 faced rota instead of a three - each rota then becomes the equivalent of 2.

I still don't understand why one of the sections is farther than the others. is it because you can't place an e-shaft without it? or is it just a wall and it doesn't affect anything? I may have missed the explanation of this

When you say it's because of, "Valvoline" the oil pressure for your credibility drops instantly to zero. You instantly start rod knocking. Keep this in mind you insanely talented and potentially full on mad scientist... credibility is important. I'm vomiting in my mouth right now, due to the disgust that has been shoved in it. Do better on the marketing front, please? I know, it's more complex than that...blah...blah...blah. Unless you mean Valvoline paid for everything the I doubt they did a damn thing in all reality.
