Properly pack a Thorens TD 125 MKII for shipping?

I have a Thorens TD MK II turntable with a Shure SME 3009 tonearm w/cart. that I will be selling here on AudiogoN soon.
I guess the best would be to sell it to someone local, this isn't always an option.
I do not have the original packing, box and material.
I would like to pack this properly as to avoid damage during shipping.
The chasis floats, how does this secure for shipping?
I will remove the platter, head shell and dust cover and will double box with plenty of packing material.
Any advice on this would be greatly appreciated.
Thanks, Rick.
