Q bond

[timbo]

Hi, has anyone used this product? I have an XBR carb which, for some crazy reason, a previous owner, had hacksawed part of the pilot screw inlet. In other words, when you screw out the pilot screw by the correct number of threads, it is hanging on by barely one thread! Q bond comes with two bottles of adhesive, a bottle of grey powder, and a bottle of black powder. It was suggested to me by someone who renovates carbs professionally, and he has used it to successfully repair broken carb bodies. So it sounds good stuff

 Hi Timbo, just put it up on google and there it is. It looks a very easy product to use on a lot of

 materials. If you decide to try it let us know how you get on.

Just used it as you would superglue to repair a broken tail light lense. Seems pretty strong. Then repaired the plastic threaded part of a choke valve. It had sheared in two half way along the thread. Put the liquid on one ragged edge, sprinkled some of the black powder on, and pressed the two bits together. Again, it seems a strong fix. Still havnt fixed carb yet. For that you sprinkle on some of the grey alloy powder.

Ok, I finally got round to repairing the broken pilot jet boss on my XBR carb this evening. Fire lit, snowing outside, and a couple of light ales on the go. So does Q bond work?
Absolutely! I'm impressed.
Tony had lent me a knackered carb with the same problem as mine. So I hacksawed off the remains of the pilot boss from his carb leaving it flush, then I ran it up the tap, (M6 x 0.5, an odd size, if anyone needs to borrow mine, I'll post it to you). I then fed the tap into my knackered carb to try and marry things up, backed off the tap, and applied the adhesive to one of the mating surfaces. Fed the cut off bit down the tap and held the two pieces together. I dripped more adhesive around the join and sprinkled on the grey powder, then more adhesive on top. Then wound out the tap which was already seizing solid due to the adhesive 
Anyway, it all worked a treat, my fingers are covered in glue, but a solid join appears to have been made.
I then decided that while I was at it I'd try to repair Tony's knackered carb. I will not bore you with details but I was eventually able to totally replace his pilot screw boss with a couple of bits of scrap alloy, drilled and tapped, and it appears to be a strong repair, and two XBR carbs are now serviceable again 
Plus I learnt stuff in the process

Cunning. Resolve. Brilliant! Well done mate.

I've never heard of that pitch on m6 either. M6 doesn't register as having an extra fine pitch in ISO stds. Go figure!
