Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Is my old hub to small

So I've been converting an old bike that I got on craigslist. It's a Schwinn Le Tour II from I believe 1976. I've got the original hub on the back and I wanted to know if it will fit a modern sprocket. Basically, I am worried that they changed the standard thread size at some point and if I buy a sprocket to go back there it won't fit.
I was thinking of getting something like this:

I know this is probably a newbie question, but I would rather not waste money on parts I can't use.

Your hub doesn’t have lockring threads and should not be ridden as a fixed gear if you value your life.

It's not recommended but you can run a cog and a bb lockring, that said I wouldn't advise doing it. Put a freewheel on there or find a new rear wheel.

I wonder how many people actually die in bike accidents....
https://www.aafp.org/afp/2001/0515/p2007.html

No I don't. "Bicycle-related injuries account for approximately 900 deaths, 23,000 hospital admissions, 580,000 emergency department visits and more than 1.2 million physician visits per year in the United States."
So .15% of bicycle injuries result in death AND..."Head injuries occur in 22 to 47 percent of injured bicyclists and are responsible for over 60 percent of all bicycle-related deaths."

I doubt it would kill the guy to throw a cog in his old hub, put a bottom bracket long ring on over that, and take it to a local machine shop and have them weld/tack the lock ring on.

Lies, damned lies, and statistics. There's no mention in there of how many bike accidents are caused by malfunctioning equipment, or how serious the accidents are when malfunctioning equipment is found to be the cause. Suicide hubs are dangerous for new riders.

as said by ufc eric that you can use a cog and BB lockring but i would advice using brakes if you do this setup. I've run it on my freewheel side for sometime with minimal skidding but you do run the risk of stripping the threads

Running a fixed gear without a proper lock-ring setup and no brakes is not safe. Can we at least agree on that?

Why are you so serious all the time? You seriously take all the fun out of the internet.

There is no reason to suicide a hub. You can find used fixed gear wheelsets for less than $50 on CL.

Also, welding/tacking a lockring to a hub is a pretty stupid idea. Not because it won't work, but just because it's stupid.
