My Son In Law used to install satellite dish's, and with every dish there was a round bubble level to be used with the install. He gave me several. I sit one on my 10-10 scale and took a section of 2X4 as a platform for the scale and carved places for the "feet" to rest and leveled it on my loading bench on the base. Works great, took me about 30 minutes to complete. If you want one of these bubble levels PM me your address and I'll send you one.
