Title: Another Torium Trouble
Post by: handi2 on November 12, 2018, 08:07:22 PM
How these reels get this way I dont know. Almost all of them corrode inside but this one takes the cake. It did clean up and with a couple of new parts its back in action.

I see this sort of thing on quite a few Toriums and Tekotas that come into the shop. The problem, of course, would be eliminated if there had been a thin film of grease on all internal parts -- including the internal end cap and frame. It can easily become a long term problem because the reel is made of cast (not machined) aluminum and is not anodized.

Uh Oh-time to check the new toy and do some preventative maintenance.

Did it look bad on the outside too? Any clue that it was that bad inside?

Hmmm, glad I donated mine. Are there any other knowen reels with cast aluminium, that can end up like that?

All brands have some cast aluminum reels. If they aren't 100% waterproof then they can wind up like that if they are cast or forged.  Neglect will do it every time.       Rudy

That looks like it had a dunking or two and several years of saltwater use without any servicing.  I've got several tekotas.  None will ever look like that.

If you give them the Tani treatment they last fine, all they need is a decent coating of grease on all the surfaces. Mine are still perfect and they have done a lot of swimming. I dunk mine in a bucket of weak soapie water if they get soaked in the salt. With the reel in the picture it clearly was soaked and left as is.

This was the worst ive ever seen and I've seen hundreds of these reels. They are very popular.

I have a bunch of pictures similar to this one but not as bad. If you dont pre service these reels they will corrode.

A good cleaning and a run through the Ultrasonic Cleaner got 99% of the corrosion removed. The frame was sprayed with TSI 301 and scrubbed in with a greasy toothbrush. No worries of corrosion again. The bearings were still good sans the bearing under the drag star. They always rust. I replace them with a rubber sealed bearing packed with grease.

I said I was done with reels for a while but its in my blood to fix something every day. If not I get bored really quick.

Wow, these reels are not anodized? Wouldn't matter if it was forged or machined; no anodizing = trouble.

Ok,
So, I have read people praise forged frames over cast for years. I'm not certain how a cast frame corrodes more than a forged frame? I'm not doubting its the case, I just don't understand it.

That reel reminds me of the reel I saw at Ken's Custom in Oceanside...

Yeah, forged vs. cast, what's up with that? Something to do with anodizing?

Keith,
You can't keep a good man down. ;)
Fixing things gives me a sense of accomplishment too.
I very rarely pay anybody to fix things with my Cars, House and especially reels!

As I understand it, anodizing is a layer of controlled "corrosion" that is applied to the bare metal. It acts as a protective layer against the bad corrosion and can be given the cool colors we so love. Don't know if machined/forged frames corrode less, but they are structurally stronger.

My Saltist BG frame is cast but has heavy black anodizing so it resists corrosion very well. The older Saltists were painted and if the paint chipped, corrosion would start to form there.

Just my 2 cents.   ;D

My understanding is that cast aluminum cannot be anodized; only machined aluminum can be anodized.

All aluminum can be machined. I don't see why it is not possible to anodize all aluminum. Forged aluminum is just moving the molecules around to give it better grain structure.       Rudy

I think it works like this:   typical cast aluminum parts will not anodize successfully, but it is possible to cast  and anodize  aluminum with the right methods.


A longer explanation:

Cast aluminum is more porous than rolled bar stock.  So it is typically a bit more difficult to get a smooth defect free surface for anodizing.  But a "toothy" surface is ideal for powder coating which can be more corrosion resistant than anodizing if applied properly, and if no mechanical sliding surfaces are involved.  Also cheaper and less rejects than anodizing.  So why not paint?

In addition, specific alloys are used for casting that typically include silica, and metals (e.g. copper) that cannot be anodized, so there ends up being spots on the surface that do not get anodized or have a poor appearance.

There are methods/alloys  to create cast aluminum parts  that can be anodized, but the casting and anodizing process is more expensive than standard aluminum casting.   Plus the process needs tighter control.

My guess is that most reel makers use standard casting for low cost parts,  and when they need to step up in quality, the difference in cost and headaches for a machined bar stock part vs a machined anodizable cast part often makes casting not worth it.  Plus "machined bar stock" is a marketable feature.

I didn't consider contaminates from the casting media. I haven't heard of a reel that was CeraKoted from the factory, but in all honesty i is what should be happening. Easy to get an amazing finish and cheap, plus corrosion and wear resistance that puts anodizing to shame. I know a manufacturer wouldn't use CeraKote, but many commercial similar alternatives are available.

I have 2 new Daiwa BG spinning reels with cast frames & a black anodized finish. (4500 & 8000) So I guess it is not that expensive or difficult to anodize cast aluminum if they can do it on $100 reels.

I have several of the new BG's and I like them.
Every thing can be done cheaper out of the country.
There is no way around it these days.
Tires, Stoves, refrigerators, dishwashers, TV's. You name it.
You think you are buying American, but there is a truth behind the mask.
