Yes, but you'll want to have some means of checking that the fork remains aligned after you've spread the ends. If one blade is moved more than the other, you'll have handling problems when riding: the bike will pull to one side or the other, requiring constant intervention on your part. There are tools to check this, e.g. the Park FT-4 among others
