Prop Shaft

No you can't borrow it. Let's here your answer on why they wouldn't be similar props? Educate me.

Whats wrong here

Whats wrong here

You not holding it?

Okay, fine. Other than left and right hand rotation, what is different in the design?

None. But its ANOTHER die, and ANOTHER minimum run. They haven't invented the CNC that can fix that. How many does he sell to teams needing right hand props. What's the recovery. Who has he sold props to so far.
Like I said, things may have changed since I talked to him about a prop, and he was very interested in getting into circle boats, thanks mainly to Tony.
If he did invest in a set of dies, kudos to him.

Does not change the failures that I have seen with his props, and the failure are in no way was a reflection of his product at all. When the outer edge of the blade peels off, it has nothing to do with how the prop was constructed. Heat possibly, but I more than little suspect it is more in the "tune" of the prop. I wouldn't even want to bet a dollar that the prop went untouched after Ron made them. I knew they went thru an additional surface treatment after Ron delivered them. Its possible that wasn't the only work done. If they weren't "tuned up", then its entirely possible that Ron simply made/duplicated what was given him.
I have a prop tuned by Gibbs that is wicked fast, and I would consider using it for a kilo attempt. But I would NEVER stick it under the boat for a GN race. It would never finish a 20 lapper. If I gave to Ron to dup, and it failed, whos fault its that, mine or Rons?

Well if Marc's numbers are right, and he has sold 100 props to the drag guys and river guys, which I don't think would be hard to do, then he has almost double downed. So he's recouped his investment.

Those numbers are straight from Joey and Ron's mouth!

You still don't fucking get it!

[SFV2RVR]

You don't seem to fucking get it! Call fucking Ron then and have him explain everything I just told you, and then you can backpedal even more and tell everyone your wrong! Oh who am I kidding...you would never admit that your wrong!

You see anything in common here?

Like I said, things may have changed in past couple years. If he took that leap of faith, good for him. I hope he sells 1000s of them. I know of two teams that have bought props from him so far. So he has his work cut out for him to move that many.
I know Rankin has least a couple. The GN44 is on at least the 2nd one. Buckles may be running them. I have sent an E mail to someone I think could be running one.
Know any others. Looong ways from the hundreds your taking about UNDER DRAG AND LAKE BOATS!!!

I guess.
The point that was started here was about shafts failing, and the possibility that 80 boat pitched ear that took out the shaft.
Whether it was the prop, or the shaft is meaningless. In either case it is not indicative a material failure, or poor machining, and has zero bearing on any of us, and virtually nothing to do with the other failures that started this thread. We've brought valve spring failures in Nascar into a conversation about daily drivers. There is NO connection to what is under the top running SS and wants under ANY of our boats, or the ones than run the enduro. Its different animal. We might as well be discussing the proplems with camshafts and lifters while we at it. Know any enduro, circle boat, ski racers, drag racers that suffer the camshaft issues the SS guys do. So why are we even discussing the issues with the skinney ass propshafts and razor blade thin props. It ludicrous.

IF the 80 boat did pitch a blade, it has NOTHING do how the prop was constructed, If it wasn't the cause, it still means jack shit. The prop and shaft are destine to fail. Failure was built into both from the beginning.
Like a top fuel motor. It MIGHT live to the end, but don't turn it around and take back to the start line. Its spent. 3.5 second of life is all it had in it from the assembling. Lets not wonder why they burn pistons, torch valve and hammer bearings, and question the material and manufacturing.

You bring up an interesting point. More than were it came from, or the yahoo that stuffed into the grinder, I question what the "retailer: sells it as, and what the producer sold it as.

Case in point. Years ago, Comp Cams/Racing Head Service bought out Pro Topline heads in New Zealand. They changed the cast in name and logo on the head to RHS. They sold 1000s of sets of them over the years as 356T6 virgin aluminum.

Along come some shady POS that makes a dead ringer copy of them out of China. They are shit, and the aluminum is dead soft crap.

This goes on for a few years, and the POS crook selling copies is selling them for less than half the RHS head.

Then, RHS sells off the tooling for the iron head to AA Enginequest, and the aluminum heads no longer have the cast in logo over the exhaust, and have the RHS CNC's on the end of the end of the head. They look more like the copy than they do the original head.

Now when you go to RHS's website, there is no mention 356T6 virgin aluminum. Its just lightweight aluminum casting.
They do have engine blocks that say 356 T6, but not heads, Ford, or Chevy, big or small block. And the price fell by over 35%

Now you tell me why you think that is.

I 'am not nearly as concerned with where the material came from, as I am if its REALLY what it is claimed to be, or a "similar" material that is "just as good" that was bought by the retailer. Either to raise his profits, or doing me a HUGE favor my saving me some money. With my $2000 prop hanging off that shaft.

[gn7]

I have no idea why that is, I'm not a retailer. My guess is they farmed it to China. But for one retailer to state that another retailer's product is shit because the material came from China is retarded to listen to. Especially when the material in question is a high grade stainless or exotic if you want to call it that.

I agree. My point was, that they aren't so much farming the heads out to China, but the heads are no longer labeled as 356T6 virgin, which means they can be any crap recycled alloy, because there is no claim it is any thing but lightweight aluminum. So is a beer can, and widow frames.

As far as prop shafts, is the material REALLY XXXX, or is a "similar material"
Anybody have or seen a cert for the material? Or just taking the word of the person cutting the shafts or his supplier? There are counterfeit DVD and Rolex watches and everything in between. Bogus parts have ended up in jumbo jets. It wouldn't be a stretch to find a bogus shaft in a boat.
Its not that China can't produce the stuff, They can launch a satellite, and shoot it down from a land based missile, and have done both. But the country does have a reputation for looking the other way when it comes to bogus stuff. Counterfeit U.S. money here, and you go to jail. Countereit U.S. money there, and they take your plates away and slap your hand. Counterfeit Chinese money, and they execute you at sunrise.
