J B WELD

Can anyone tell me where I can buy JB Weld?

do any of the larger diy stores sell it?

Thanks

Dougie

Hi Dougie,loads on ebay.

Regards Mark P.

Hemingwaykits sell JB Weld

Yep I get mine from e-bay, about £5 inc postage (half the cost from hemmingway) just make sure you get the black and red tubes not the quick set or marine versions

Hi Please can someone tell me what JB weld is as I have not heard of it . Thanks in advance

Maurice.

My local hardware store stocks it Dougie - but it's very unlikely you live anywhere near Wokingham.

However, I do try to buy stuff there whenever possible, simply becuase he stocks stuff I can't normally get at the DIY stores (JB Weld, Gorilla Glue etc). It might be strange to say this - but in some ways he has a much wider/better range of stuff than they do (maybe I mean its a bit more specilaist?) and is also pretty knowledable about it too. He clearly talks to his other customers about what works best for them.

It may be a bit more expensive, but I feel it's worth my while to try and help him stay in business. My purchases are generally small in nature and his prices not so bad and sometimes (to my surprise) he's cheaper than our local Homebase.

Of course you can probably also get anything you want mail order on the InterWebby these days - but then when you want something to finish that urgent plumbing job for your Manager - that might not be quite as handy.

So give your local hardware shop a call Dougie!

Amazon also sell it !

Maurice, its a two part epoxy adhesive/filler that will stick metal to metal and can be machined as well, it also has quite a high working temperature.

You can also seal leaks in Honda XL250 petrol tanks with it.

Just FYI it works to 500 deg F max continuous, is not recommended for use on car exhaust parts or in any IC engine combustion chambers, and must not be used in any pressure vessel, hot or cold.

Other than for those things/conditions it is a great repair epoxy, but certainly no better than other good brand name epoxy like West System or Devcon or Loctite.

JD

I use it to glue the hull of my flash steamer together as ordinary epoxy softens with the heat on the joints and JB seems to be holding OK.

On certain parts the marine ply starts to char with the heat and JB is still holding.

It has been used to pad racing two stroke crankcases.

There are other industrial epoxy adhesives for many different applications but can be very expensive if you can find a supplier of small amounts.

Hi Phil,

A word of caution re JB and Petrol, modern alcohol "fortified" petrol eats epoxy!

Hi Jason

Why do you not recomend the fast set or marine type. I just finished my high temp JB weld ( red and black ) and was thinking about getting the fast set next time. I find that the high temp needs at least 24 hours to set. When i do not require the high temp this long time is a bit of a pain.

Mike

If you don't need the high temp then you may be OK I don't know how the others set and if they are as machinable, never tried the others. Also the 24hr one has a 65% higher tensile strength so if bonding parts even if they do not get hot the 24hr will be stronger.

Really depends on what you want to use it for as you could get away with a car body type filler or one of the putty types whic can be formed more into a fillet and need less work when set. These fillets were done with Milliput and needed no work once set but they are onlydecorative and not structural.

I do find that if you are making large fillets the JBW can slump a bit and in that case I use something a bit thicker like plastic metal, you can se I have used it here to form the fillet around the main block but JBW for the smaller parts which were stuck with it and the fillet formed from the excess, the blocks are also screwed so the filler is only cosmetic.

I used JB Weld to glue a light alloy gudgeon pin carrier inside a cast iron piston on a 2.5cc diesel model aeroplane engine. Its been working most weekends, flying a control line model. Good stuff!!

cheers

Bill

Thanks Jason

I have used the high temp stuff to repair a traction engine cylinder (1/3 scale) where i drilled too deep. I also find that it does slump quite a lot. I also use milliput as a filler in where i just needed a gap filler. I suppost it is a case of having 3 or 4 different types for the partiular work in hand.

Mike

For large gaps, I use araldite, or similar, mixed with filings of the same metal, you really need to use the slower setting stuff for this so that you can get as much metal mixed in as possible before it gets too thick. You can do the same with wood and wood glue, a help with pattern making. Ian S C

and it will hapily bond to cast iron
