I presently have a 16" surface cleaner from Northern tool. It has beed working well since I got it. I have plans to make a bigger one. I think they came from Hot Wizzard. Would the spinner from the 16" work on a larger one made from a barrel bottem. I plan on using a plastic barrel. Another question, is my 5 gpm, 3000psi large enough for this big of a cleaner
