So ream out the wheels...if you can't take off .075mm with a bit of
emery you don't deserve to be posting in UK.d-i-y

I know absolutely nothing about metalwork, its not something i have
ever had to do. (does this lack of knowledge in one area mean that i
dont deserve to post here? its never stopped dimm and his dual combi
********)

Is it worth getting a sheet metal fabricators (i know one) to do this
for me, or is it something that can be done by hand? I suppose i'll get
the tinned reply, "if you have to ask then its best to get it done by a
pro", but if not, do i need to buy any special tools to do this.
