Thank you all for the nice comments. It is about 3 months old now and still very solid. I have used it with almost all my equipment in the basement shop. Steve DeVries from  out guild sell complete plans for the one he built that has more range than mine because the arms are longer. He used his for installing upper kitchen cabinets.

Hi Swirt, with a big load on it, it has some sway  side to side except when it is all the way up with the arms almost vertical. Then it has a lot less sway!

Cheers, Jim
