I just received a pair of low millage cylinders form an Italian Guzzi breaker, who packed the cylinder very poorly. (no padding between the cylinder in the package, so they were hammering against each other duering the shipping process). He refuse to accept responsibility, and blames the postal services - the easy way out. I'll leave it at that.
What I meant to ask was, is there a good way to reattach a peace of broken cooling fin. The very thought of a damage like this annoyes the heck out of me.
Would JB Weld be a solution?
Will it stand the heat?
I want it to look nice!

The gold standard is to TIG weld it back on if access isnt an issue. If missing you can build it up with tig and dress it back to shape.

Not having easy access to a Tig welder I would pin it on using a piece of bicycle spoke.
If you go to a shop that repairs cycles they will give you a complete wheel for nothing, its the handiest stiff wire you could wish for.

If you paid with PayPal regular transaction simply dispute the charge and PayPal will side with the buyer and make the seller refund your money.
This is also why if I accept PayPal as a form of payment it is F&F only. Regular transaction give all the power to the buyer. They have 180 days after a purchase to dispute a sale for whatever reason. If you sell a shirt and on the 179th day the owner gets a stain on it thay can dispute the sale and say the color faded and they are not satified. PayPal will most likely side with them and make the seller refund the money.
I also like to use and accet PayPal friends and family so PayPal does not get the 3% transaction fee.

JB will work and if it's back in close to the cyl walls it won't be seen. put a tiny bit on the cracked edges, put them together and let dry completly. then build up a layer from the bottom (unseen) side for extra support.

Take it to a welder and have them build up the fin with a TIG. Then you can grind and file it to shape. We did it all the time on aircraft cylinders. The boss welded I shaped.

Thanks guys! I really appreciate all the good advice given here!

A minor point and a bit off topic, but PayPal still gets the transaction fee, they get it from the purchaser not the seller. PayPal is whole WRT fees.

Transactions using the family/friends option incurs no fee to either party.

Is that the top or bottom of the cylinder? If it's the bottom and not easily seen, maybe just forget about it...Other wise have it welded, a shop may charge 35-50 bucks ...

Using F&F the buyer buys a $10 item s/he pays $10 and seller gets $10. There are no fees.
Using traditional transaction the buyer buys a $10 item s/he pays $10 the seller recieves $9.70 because of the 3% PayPal fee.

Go with the JB Weld, the regular stuff, not JB kwik. I used it on BSA head fin and its still together after 20 years.
If you sand the surface well after its cured it will match the alumnum.

I thought PayPal gets their ounce of blood no matter what...maybe that only happens if the payment is made via a credit card vs a bank account.
This is from PayPal's website:
"What's the difference between friends and family or goods and services payments?
You can send money to friends and family or pay for goods and services in the Send & Request tab at the top of the PayPal page.
If you’re sending a personal payment, payment types include:
Send to a friend - used when sending money to a friend or family member.
Paying for an item or service - Use this payment type when buying an item or service from someone. When you make a purchase, the seller pays a small fee to receive your money.
Send to friends abroad - used when sending money to friends and family across the globe.
Send a digital gift card - used to send a gift card that can be personalized with a message.
You can make a personal payment to anyone in the U.S. for free. Just make sure that you pay for the entire payment using your bank account or, if you have a PayPal Cash account or PayPal Cash Plus account, your balance. There is a small charge for payments made with a debit or credit card."

I've got money on acct with them which I get no interest from. So they do make money handling my money. And I'm sure they even make money on the no-fee transactions.

I decided to keep the cylinders, rather than go thru the hassle of returning and getting a refund, which was not the sellers attitude to give.
Never doing business with him again.
I used JB Weld regular, after also sanding the edges for a supporting layer. I did that once before, on a Lario cylinder, and it still sticks after several years, although it bugs me insanely living with a broken fin.
Second to a non broken fin I guess, but JB weld does wonders in some areas.
Thank you for all you gerat advice!
Cheers!!

Hi Brian,
If you ever get really tired of living with the broken or JB welded fin, take a ride over the bridge and come see me in Fyn, We should be able to weld it back up or back on.
I have a set of old T5 heads where there are some broken fins on. So I will try and weld those up to get a feel for it. If it turns out well, then I should be able to fix yours too.

From your photo Brian it is on one of the outer surfaces.
If the JB looks like failing it should be a reasonably easy job to tig it back together. Just don't lose the piece!

Gotta love WG. :thumb: Have I mentioned that before? :smiley:

Has anyone tried aluminum brazing? I did a few test pieces and it seems to work reasonably well.

Yeah, I've done that. It's better than nothing if you don't have TIG. Just MHO. You can also weld aluminum with oxy hydrogen. Done that too. TIG for the win.. :smiley: :wink:

I've done it with oxy/acetylene Chuck and it's VERY tricky. The instructor said you had about 50 deg C in which to play with. Look for the surface to crack and that's it! I accomplishes the task but would advise TIG any day!

If you mean the 'Lumiweld' Kit (or similar), then yes, very impressive stuff, and all with a 'normal' Propane/Butane Gas Torch.
Not having to melt the Parent Metal takes a lot of stress out of the equation!
And as for PayPal F&F, I'm fairly sure if you use that, there's no buyer/seller protection available, as it's not intended to be used for purchasing goods/services.
-

I can believe that!

I tried alumiweld on a fin and didn't have any luck getting the head hot enough to melt it. I figured the head was doing what it was designed to do by shedding the heat. I guess you could preheat the head in a oven maybe the would have helped.

Hej Ulrik - fellow Dane :thumb:
Thanks for the offer to try fixing my my possible nightmare, if JB fails.
I'm sure the rest of the WG guys on this tread would like to hear how your attempt turns out :cheesy:

As a suggestion, what about a discreetly placed blob of hi temp silicone sealer on top and bottom of the JB welded fin that also sits on the fin above and below as a sort of vibration damper and support as well as ensuring that if the JB repair fails at least the broken fin will be retained for a further repair attempt.

Hej Brian,
I will be sure to let you all know how it works out :laugh: I'm currently in Senegal to align a girth gear on a cement mill, when I get back to Denmark I will give the fin welding a shot :grin:

Agreed, its good stuff,
IIRC it won't stick to steel. On that assumption, once you have prepared the edge, you could clamp a couple of bits of steel either side of the fin and essentially cast some eplacement metal to fettle to shape

The way it was done on both heads of my V7Sport was the broken fins, 3 or 4 on each, were built up with aluminum weld then ground to shape. Maybe a little bead blast to give them texture. You can't tell which one were fixed. All for $85.

Those damn girth gears, getcha every time!

Yes the gold standard repair. Alas not many are prepared to pay to do it right.
