I have looked everywhere and can't seem to figure this out. Other than buying the special tool to hold the piston at tdc while performing the test is there some thing to make or a way to hold it at tdc while doing the test. My friend has my manual and he says it looks like a special tool and the piston needs to be at tdc.

Only put it in TDC, and make your test. You don't need to hold it.
