WTD- 19T cassette cog, or cassette with a 19T in it

[scant]

hi all
building a singlespeed & according to the various singlespeed chain tension calculators I need a 19T cassette cog to achieve the correct tension. Does anyone have one they can spare, just so that I can check its correct before I get a specific singlespeed cog. worn is fine.

thanks

Think I may have one with a tooth missing, will go and check

Take care if you're using a 'magic ratio' rather than a tensioner or horizontal dropout (not sure if this is what you are doing but looks as if it might be) because as the chain wears there can get a bit of slack

well aware, but thanks for the heads up anyway
its for a rarely used bike, so chain stretch aint gonna be an issue
