I think its probably possible to use tie downs, but you would need make a simple platform out of wood to get your hands under the set. So a simple square frame with four legs high enough off your table.

as for the tie downs.....you saw my set...how would i apply a tie down situation there? Getting ready to start over from scratch i think. Feeling really lost and i seem to be the only one around my area so its hard to collaborate and get to see stuff done in front of me.
