Front chainring conversion

Hi guys

Building my fixie here, it's a work in progress, anyway; Next stage I need to do is to convert the front chainring from double to single. I understand that you need to either saw off your old chainring bolts, or to buy new shorter ones. I would like to know why you need new ones, the best answer I've had so far is 'they don't fit,' but I just don't see how. Would washers work at all?

Regards
Luke

....I understand that you need to either saw off your old chainring bolts....

This one.

Double chainring bolts are longer to allow for....the thickness of 2 chainrings. They are 2-piece recessed bolts so they only tighten to a certain limit. Save yourself the hassle of sawing, buy a set of singles off ebay for a few quid.

Nah, sawing down your old chainring bolts is more economical and environmentally friendly.

i've chopped old ones and gone the way of the intellect and purchased new ones.

ancient chinese saying: "you buy single speed bolts, you buy happiness"

based on experience, go chinese.

I was being sarcastic.

^^ I tried to acknowledge this in my post, but alas, apparently people actually DO saw chainring bolts.
