Joe,
I drilled a couple oversized holes in a 4x4 (~8" long) at the approximate angle, and put these over the threaded ends of the gear legs. I put the tail on a table with some padding between the tail and table. You don't need the table if your engine is hung (but you do need the nose gear or some other support). At other times, I put a sawhorse on either side of the firewall and a piece of 4x4 across the sawhorses, along with the tail support. This works well with the engine already hung. It's easy to put the sawhorses and 4x4 under the firewall if you lower the tail (while the main gear is on those blocks) and just build up the crosspiece between sawhorses to almost touch the fuselage. Then simply lift the tail and slide the table and padding under it. In this configuration, the main gear legs will be just slightly off the ground.
I probably don't need to say it, but be careful with your center of gravity when the fuselage is on blocks - support it at the far ends wherever possible.
cheers,
greg
