Converting a bike to singlespeed/fixie

Hi, I am looking to convert a couple of steel vintage bikes to singlespeed/fixie. The first one is a Dawes wildcat MTB, which I already have, and would like to convert to singlespeed/fixie flip-flop. The second, which I do not yet have is either a Dawes galaxy or Claud Butler majestic. Both bikes will need a certain amount of restoration, but mot much.
I was considering doing the conversions myself, but I have no experience and would like to start riding them as soon as possible so decided to let someone more experience do it.
Does anyone know of anyone in the Windsor area that might be able to do the job?

Also, as I do not yet have the road bike, I am considering buying a fixie if I can find one that suits my needs. I am looking for british reynolds 531 vintage frame. I have been looking at tourers as I like a relatively upright riding position and was under the impression that their geometry is more suitable. I am looking for 25” frame or thereabouts.
Many thanks

Old steel framed bikes are the easiest to convert to fixie. The horizontal dropouts means chain tension adjustment is easy and the screw on freewheels have the same threading as a fixed sprocket or single speed freewheel. You can’t fit a lockring but for the road, it doesn’t matter.

Conversion was so easy it was normal practice in the 70s for us roadies to convert our racing bikes to fixed during the winter and back to 10 speed in the summer. All that was necessary was to swap the freewheel for a sprocket and shorten the chain. Everything else (mechs, lever, cables) was left on the bike.

To cnvrt4fxy for either the Dawes or the Majestic you need a front Aerospok sprayed pink or green and a ratty black NoLogo wheel for the rear. Silver risers or straight bars for the front cut down narrow with dirty mushroom grips. You've asked at a perfect time really, the forum (and the whole of London for that matter) is experiencing a bit of a fixie revival.

Oh sorry, I was confusing fixed wheel with ‘fixie’.

Thanks all for your comments. Hopefully I will be riding them soon!

Same same.
But you left even the rear derailleur on there when you rode the fixed wheel?

Yes, as it was only meant as a temporary conversion. This was in the days we only had one bike for everything; training, racing, time trials, a bit of touring also. Mudguards on for winter, off in summer. Those were the days! Mine was a Condor Italia.
