Hi guys and Merry Christmas.
I have a question on JB Weld. I've never used it before, and according to the directions it says mix equal amounts together. What happens if your heavy on one or the other? Won't harden? Poor bond?

One is the resin and one the hardened. So if not enough hardener it will not set as hard, too much hardener it harden , but will lack strength.

I've been using JB weld for some years now.

The bigger question is why wouldn't you mix equal amounts together? Never not mixed it together rather equally to give you an answer, but Clint's answer seems reasonable;)

Lot better than West Virginia Chrome (AKA duct tape LOL).

Equal amounts give good work time and proper hardening. Lack of proper hardener will cause slow curing time and possibly not cure at all if not enough hardener.

I mix it by applying a dollop of the black resin and along side a dollop of the white hardener trying to get approximately the same size dollop from each tube. Then thoroughly mix to a uniform color and apply. It does creep quite a lot before hardening, so best to have the part that you are gluing level, then watch for excessive creep. It wont hurt to screed it back in place if it is still liquid but don't move it if it is already starting to cure.
I use JB Weld on lots of things but it has it limits as to what it will stick too. Some types of thermo-plastic wont bond well with it.

My favorite mixing pot is a small plastic container that my scotch brand black vinyl tape came it. The hardened resin can be popped loose easily (note that it is one of the types of plastic than doesn't bond well). Softer plastics like PVC can sometimes bond well. I fixed my tractors fuel tank 7 or more years ago and it is still holding.

When JB welding, I put a lighter lens in my helmet. That makes it easier to see equal amounts, compared to doing it by touch. :laughing:

Surface preparation will help the adhesion capabilities of just about any epoxy etc., etc...
Even microscopic scratches help a good bit on smoother surfaces...

Nobody mentioned that getting equal parts is an EXACT science requiring precision scales and stuff!:) Like epoxy, the eyeball test is good enough.

Thanks for the tip, Bruce. I will have to try that.

I think the proper name is truly "duck tape" derived from it utilizing cotton duck material. Further proof is that it doesn't work on ducts.

Looks like both names may be correct.

From:
Duct tape - Wikipedia

Their new unnamed product was made of thin cotton duck coated in waterproof polyethylene (plastic) with a layer of rubber-based gray adhesive (branded as "Polycoat") bonded to one side. It was easy to apply and remove, and was soon adapted to repair military equipment quickly, including vehicles and weapons. This tape, colored in army-standard matte olive drab, was nicknamed "duck tape" by the soldiers. Various theories have been put forward for the nickname, including the descendant relation to cotton duck fabric, the waterproof characteristics of a duck bird, and even the name of the 1942 amphibious military vehicle DUKW, which was pronounced "duck".

After the war, the duck tape product was sold in hardware stores for household repairs. The Melvin A. Anderson Company of Cleveland, Ohio, acquired the rights to the tape in 1950. It was commonly used in construction to wrap air ducts. Following this application, the name "duct tape" came into use in the 1950s, along with tape products that were colored silvery gray like tin ductwork. Specialized heat- and cold-resistant tapes were developed for heating and air-conditioning ducts. By 1960 a St. Louis, Missouri, HVAC company, Albert Arno, Inc., trademarked the name "Ductape" for their "flame-resistant" duct tape, capable of holding together at 350-400 °F (177-204°C).

"When JB welding",....
Why not just use an auto darkening helmet?

Ok, here's the deal guys. When I got home last night my "main squeeze" informed me the lever broke off the (single lever Moen) kitchen faucet. When I looked at it, the part that broke was a metal thing that made the connection between the lever handle and the cartridge stem. So not wanting to replace the faucet on Christmas Eve, I went looking @ local stores for a replacement part...long shot I know.
Came up empty so I decided to get some JB Weld to see if that would temporally fix it. She's decided that a new sink should go with the new faucet but that's a Thursday job.
When I mixed it I tried to get it equal but one (black) was a little more then grey. I've bonded the parts but am waiting to install them being worried I didn't wait long enough for full strength.
That's why I had posed the question..

Well guys, first time it's a failure. Came apart when trying to test faucet. Back to the shop, mixed another batch paying more attention to portions and tried again. This time I spread some on the sides of part to get more contact area. I'll wait a couple hours and try again..

I use Moen throughout this house and can't envision what broke but guess it is kind of a skinny piece isn't it (like the older Delta's)? Cross your fingers and say a prayer.

You might try a universal handle.

Think their stuff has a lifetime guarantee - I had a part break on ours and they sent a new one out no questions asked. We were pleased with their customer service.

I'm sure it does but the timing sucks. Try to do without a kitchen sink during the holidays and you'll find it's very inconvenient. can't do anything about it either....
