Star Fangled Nut has two layers of "fins" if you place the nut sideways on a hard surface and with a smallish hammer, carefully tap around the lower fins you can push them up so that the nut starts to fit into the steerer.
Once it does you screw the top nut in a bit and hit it with a hammer until the top set of fins is below the top of the steerer by about 8mm. I use a socket as a drift to get it this far so I don;t muller the top nut.
You need a bit of hammer savvy, and a good eye. I can do this in the time it takes for a bike shop mechanic to find the star-nut tool and shamble over to the bike. One drawback is the nut may not be as tight as the lower set of fins are not biting as hard, but in practice that's bollocks it works a treat.
That's me though and I am an experienced builder of bikes and user of tools in general. If for one minute you don't have the kit or the confidence then simply JFTITABS
There is a way you can do this.
