    Just buy araldite, I found it was pretty plentiful when I was in Eurasia while back. It's pretty strong and my bud told me they use it for all kinds of crap like Americans do with jb weld.

    Actually looking at ebay you could get it from a great Britain source for only 10 quid. Just make sure you get the real stuff because it looks like China can't limit themselves to what they decide to make copies of.

    rofl true that ha ha they do try n copy everything not allways well ! but they get a mark for effort >.< from what i can tell jb weld is the best one by a long way over say araldite for strength and heat resistance ive been using chemical metal for crank filling wouldnt dare use it on my transfers thou the heat rateing on that bit of the engine only jb weld as far as i can tell will handel it without any possible issues i wouldnt mind getting hold of some i know shops here used to sell it years back

    That's only about 75 pence more than I'd have to pay at the local Walmart. Probably on par with the prices I'd see from a small town general store.

    Oh and I have used jb weld in my transfers to fix up the port work and it didn't melt or burst or flake. I think it should hold up fine like all the senior citizens keep saying it will.

    From what I understand jb weld company is international, their products should be just as available to you guys and the mark up is due to the fact that it is made in the USA, shipping isn't free so it should naturally be a bit more expensive over there vs the homeland.

    I also use an incredibly cheap epoxy line that harbor freight (a discount tool shop) sells. It's not the best but cheap enough and works well enough to justify its special needs. Jb weld is definitely a better product and I only use it where the application is considered important or I need a strong bind in a tiny joint.

    Part of the durability in the transfers is likely due to the fresh cool air and gasoline mixture that is basically always passing over it while the engine is running. That pretty significant cooling effect has got to be doing the epoxy a favor since that air wouldn't be all that much warmer than ambient Temps and what ever they are they are certainly lower than the temp of the piston and cylinder.

    Maybe instead of halfords check out an auto shop. If not there maybe hit up a nearby boat supply on the telly. I find it hard to believe that after 40 years jb weld hasn't found itself in one of your local brick and mortars, just try to make sure you get fresh product as epoxy resins have shelf lives and time does screw with the chemistry. If they have dust on them or are getting sunbathed everyday by a nearby window then don't bother as you may as well be tossing pennies in the slots hoping to get lucky. Chances are you'll lose.

    There should have been a small screw tool that came with your kit, it's about 1.5 inches wide and 2.5 inches long, which you just place over the cog and turn it using an adjustable wrench.

    You could have drilled and tapped M6 holes in the drive cog to pull it off too.
    Sorry for just coming up with this, it just came to mind.
    Use them with a bar type puller bearing against the crank snout,
    or (more risky and not recommended) 3 or 4 M6 bolts bearing against a back surface to jack the gear off.

    JB Weld is 280C max temp and almost 4000PSI grip strength, might pull a gear off, but sketchy.
    Aluminum is 10,000psi minimum yield.
    Mild steel is 20,000psi.
    Good high carbon steel is 30-40,000psi.
    Alloys are 80-120,000 if I remember correctly.

    You know those simple bearing pullers you can find just about anywhere, with the arms that face inward. One of them could work maybe, I think you might have a clearance problem if it were too big however.
