I got one set that pt has but I tried 1 inch rubber chair tips to cap over mine, They fit snug, but are still easy to get off. I drilled a hole in the end of the tip and put a small eye bolt through the hole with a washer on both sides and tightened up the nut , tied a peice of mason string in the eye hook and tied the other end to the hose, works good. Does any body know where you can get a boxed end open end wrench to fit the nut on the center section bottom bolt? They said that it was a 1 13/16 inch wrench but so far I haven't been able to find one. They told me at pt to check it after I had used the machine for a while to make sure it stayed tight. If it is loose and allowed to shift back and forwards any length of time it will egg shape the joint and cause it to break.
