Converting Rear Hub to Fixed Gear.
 

I recently acquired an incredibly old Carlton Bike, the model etc is beyond me. I've completely stripped the frame and I'm having it sandblasted or I'll just do it by hand within the week and before I go out and buy a set of 'Fixie' Wheels, I thought I'd see if anyone knows a way to convert a 7 gear Cassette into a Fixed Gear, I'm aware its a long shot but it could save a bit of cash.

Also heres the bike (Pre-disassembled of course)

Also, if anyone knows of a good set of Single Speed wheels feel free to suggest. :)

Also, in before everyone tells you to leave it geared.

Genius.

Being that the OP calls the bike "incredibly old," what are the odds that the rear wheel, if original, actually has a cassette instead of a multi-speed freewheel? Just asking because if it doesn't (or if his hubs aren't Shimano), it doesn't sound like the fixxer would work. Something to consider before ordering one.

"I thought I'd see if anyone knows a way to convert a 7 gear Cassette into a Fixed Gear..."

No, I get that he said that. A lot of folks who aren't all that well-versed in bike terminology may very well mistakenly call a freewheel a cassette and vice versa. Just trying to help him avoid a mistake I may very well may have made when I was learning about doing conversions. You have to admit, once he said "incredibly old" and "Carlton" together, one couldn't be faulted for thinking that if the bike's original it might have 27 inch wheels with a freewheel.

True. That looks like an awfully low-quality bike to have a freehub body. Unless someone put the QR lever on the drive side, that rear axle looks nutted.

Just looking closely at the photo, it looks like the OP is running tubulars, which are 700c, but the clearances to the mini fenders says the frame is definitely designed for larger 27" wheels and tires. So the bike may be vintage 1970s to early 1980s with 126mm rear dropout spacing, and it could have either a screw on freewheel or a cassette.
