And, if a piece of wood is used as a washer, it could provide a grip to hold on to - not to mention protecting your hands & feet in case your friend's aim is a bit off.If one wants to use nails, why just have someone drive nails into the wood between your fingers and toes? That way you get the sound and maybe the steel moving down against your skin but no pain. That seems to me the safest route to go. But one must also be tied to the cross before the nails are driven in. Be safe.

I think something like this has been used in some films.
