Now I reckon it'll be sufficiently strong if I just mount it securely, but general thinking has it that we should roll the edges, either in a false wired edge or a real one. A real one is a fiddly job, but not that difficult. However, my son insisted that the aluminium would need annealing, just like when he worked for a classic racing car restorer. Now, I have always shied away from annealing aluminium. The softening point is over 500 degrees, the melting point around 600, so you'll always be dancing on ball bearings. That and the fact that I've actually done quite a lot of small time metal bashing in ally without any problem. I bashed it into shape over wooden forms to make a gutter system on my Fox van, I made sub fibreglass shapes to support the GRP repairs on the same vehicle. More recently I made the A-pillar shut face panels for my son's Triumph Renown....all without resort to the annealer's flame.
So, I thought, what's so difficult about rolling 6mm of it over a bit of wire? Well, erm, nothing, it turns out. Look.....
I will, when I can find a bar of Simple Soap, try this annealing lark. It seems to help, but I don't see it getting done noticeably better than this. This took me maybe 20 minutes, after I'd chopped this little chunk off.
I mean, considering that I just had a sudden whim to try something I'd never done before and got on with it, with possibly less than suitable tools and, with little time, less than complete care. I didn't have any steel wire, but I did have some 2mm ally Tig wire, so I used that. Seems more sensible to put ally in ally. I never liked the idea of steel in ally anyway. Recipe for terminal rot.
Another ten minutes with a thumb full of 240 emery and there we are. I don't see any cracks, but maybe, doing a whole mudguard, I might have changed my mind and decided that easy beats falsely lazy:-)
