Didn't realise I'd fired the starters pistol! Lol. Ye can't be arsed with the link as, well, how many different types could there be?. they are braze on type I was looking at, though I'd tig 'em on. They just don't look substantial enough to me, especially the threads. If anyone's had a go of them let me know.. did I mention I'm a fabricator? ... and before you say it, Yes I could do my own but for the sake of a few quid I mite as well get some ready made.
