Retrofitting a disc tab to a steel fork---bad idea?
I'm interested in converting my Surly Crosscheck to front disc, because it's an all weather commuter and I would rather replace discs than rims. I'm having a hard time finding nice looking, inexpensive steel forks in that spec (400mm axle-crown, 44mm rake) and was wondering how bad of an idea it would be to have a disc tab welded on to the stock fork. I get the feeling that those blades might not hold up to the stress but I thought I might ask you all anyway.
On a related note, if I just threw on a nashbar 398*45 steel fork and called it a day, do you think my steering would be noticeably different? The bike would certainly be noticeably worse looking. But if that's the price of rims that last more than a year I may take it.
