Hi rob,
If you need larger bolts in places you can't reach back of then there's other quick and dirty ways like drilling larger hole and inserting a nut weld in place and grind flat.

Or use riv-nuts if you can't be arsed to fart about with welding

Hey Jazz

Thanks for the kind message.I think its getting there but i don't always get the same results every time at the moment. but I absolutely love welding now it still amazes me. I want to be confident enough to weld some of the chassis on the car and not need to ask a friend it they might like a ride in it first (Just in-case ). I think because I'm teaching myself there is probably a lot of bad habits going to be there.

I did think if riv-nuts originally but it seems that if any vibration occurs then these would start to wonder about a little. I really love the idea of welding the nuts in. I'm a worrier and I have used the sander to take the zinc coating off but it says somewhere the gasses are pretty bad for you. I'm not sure if there are specific welding quality nuts around or anything ? or just hold my breath and grow a pair.

None of the gases given off are exactly good for you so if welding for long time or anything you know isn't sweet smelling then wear a mask.! I wear mask all the time when welding.

Zinc fumes can give you flu like symptoms, which can take 3 weeks to go. It is probably best to wear a good quality respirator and work in a well ventilated area. Zinc inclusion in the weld won't really happen as the zinc will burn off, but for the sake of your health it is better to sand it off, while wearing a mask as the dust is just as poisonous. A lot of heavy metals are cumulative poisons as the body can't get rid of them. Fortunately zinc can be dealt with by the body.

Have fun welding !

Hey Cropwell

Thank you very much for the explanation and I will certainly wear a mask in future and I'm getting those bolts on order to make me worry less.
