I used my bottle rinser vinatorfor the first time today and I had to do some re-engineering on it to get it to work okay. The main issue I had was that the return spring kept slipping out of its detent when I was screwing it together. I called FVW and talked to Joseph and he was willing to take it back but I was all set to bottle. He suggested checking the nylon bearing retainer in the base to make sure it was seated deeply enough in the base to give the spring an adequate indention to sit on.
I noticed that there was a lot of "flash" on the underside of the base where the nylon retainer is seated.I first carved that away with an Exacto knife, then pushed the bearing retainer out from the bottom. I took about 1/16" off the top of the retainer with an Exacto knife and then cut away the same amount onthe shoulder on which the spring rests with a paddle bit. I was able to get the assembly together, but it is not my favorite piece of equipment. I think I will get a spray bottle, fill it with K-meta solution,and spray up into an inverted bottle.
