New Plasma Cutter

Just have purchased a LT5000D Lotos Pilot start Plasma cutter from amazon.com. I was impressed with how it cut on the first pass of me trying it. I had also bought a plasma cutting guide from eastwood.com but the cup on the Lotos will not fit in any way into the guides alignment ring. I am building a new ring for the existing guide. Just have started turning the new cup ring. Will post a how to once I finish with the piece and have pics
