Search for chain tugs rather than a chain tensioner. You want something to hold the wheel in place rather than to push the chain up or pull it down (). On a fixed gear, the latter will just break with the first back pressure on the pedals.
The simple answer is, as Sheldon brown says, as tight as possible without binding. But define binding. The noises you described on your chain in your previous question were symptomatic of binding or of a worn chain. The description you've given there of how you run your chain tension is tighter than I would recommend. To clarify the tensioning - When I ...
A loose chain is a fast chain. The proper technique for getting proper chain tension is to pull the wheel back in the dropouts and tighten the nuts a little past finger-tight. Don't worry about alignment just yet. Rotate the wheel and "feel" the slack in the top half of the chain with a screwdriver until it's at its tightest point. Here, it should still ...
Some things to try: Make sure there isn't any grease on dropouts, axle, or bolts. Make sure the nuts for the rear axle have some bite to them. Make sure the rear hub has some bite to it where it touches the rear dropouts. More spinning the pedals, less hammering on them. Increase the size of the rear cog, and if you need to, the front chain ring. If you ...
You could look into getting some chain tugs which basically create a link between the axle and frame. Here is an example: Surly Tuggnut
Unless I'm missing something, you should just be able to remove the chain using a chain tool, and then slide the wheel back in the dropout. This would free the chaintug from the back of the dropout, then you could rotate it down out of the way and be free to slide the wheel forward and remove it. Once the wheel's out, take the chaintug off the axle and ...
Better a hair too loose than a hair too tight..
There are two dimensions that matter: Axle diameter. 10mm is the standard, but you'll also find models designed for 9.5mm (3/8") and 14mm axles on BMX bikes. Dropout thickness. This is the thickness of the metal plate comprising the dropout when looked at end-on. The tensioner cups the ends of the dropout, so must be large enough to fit over them. Steel ...
