But that would make it a single speed bike not a fixed. I am not an
officianado on single speeds or fixeds but surely with no rear mech
you'll get chainline issues (such as derailling) too if you are not
careful.

The pile of junk I've lent to a mate in an effort to kill him has been
'converted' to single speed. No chainline issues, although everything else
is shot. Guess it depends what gear you want it in.

Well fate intervened; the derailleur packed up so I convereted it
yesterday to a 42x18. So far the chain has not fallen off, but the
problem is getting the chainset bolts to tighten up after taking the
front chainwheel off. Of course it could all end in tears if they
decide to ban the bike from the new trains
;-(

Any old chainring and a hacksaw will yield five suitable washers to take
up the slack

Did think of that but have found that the Law of Sod states that I
will need the chainring at some point; this was recently the case
with:
rear mech
frame
stem
etc. etc.
