The bolt method seems like it would be very accurate and easy, provided the spark plug hole gives a good angle to the piston. Do this method only when your relative is in another state. Otherwise he WILL use the starter to crank the engine while the bolt is in there. Even if he has to hook up the battery to do it.

thanks for the info about making sure to do it quick, I might try to bolt method first and just make sure I am very gentle while turning it.
As far as the brother in law not being in state, That is a big check! He used my Dremel last year that I have owned for 7 years and taken good care of (like all my tools), the next time I went to use it I opened the case and the wheel he was using was jambed into the Dremel so hard I needed pliers to get it out and then I plug it in and turn it on and it is completely dead. He borrowed an older extremely heavy duty Milwaukee 7 inch grinder, I figured there was nothing he could do to this thing to mess it up (I was wrong) I am right handed (so is he) and the handle that screws into the side was on the wrong side so I go to switch it.... He stripped out the threads, no big deal since it was just a drill, tap, and heli-coil but I had to drive to the hardware store to get the heli-coil and the tool to install them.
We live in a nice neighbor hood and I should not have to lock all my stuff up but that is what I have to do..... I have to make sure that the garage doors are locked and anything of value it put up where he can't find them.
OK, enough venting for now.
