they are very big. I have a cast iron table top 5x7 that with some effort I can move by myself. The only 8x10 I have ever seen I would not try without at least one other. The head won't come off but the top part will and you can remove the heat glass and light bulb. The thing that is of the biggest concern is what happens when the light bulb burns out. They are next to impossible to find unless you convert it to an Aristo which is what I did for a while with mine. I would just eat some Wheaties that morning and lift it on to the lift and go for it.
