Hello,
My first post, looking forward to receiving my Crack next week. I also use the VPI 16.5, I have modified mine though. I added a 4.5" ventilation fan with a switch, allows me to clean longer. The spindle doesn't even get hot anymore! I also replaced the cork mats with a piece of 60 Duro neoprene. Less chance of contaminating a clean side than with the cork, and you can clean it. IMHO the most important component of a RCM is the cleaning fluid. I have tried everything, including DIY. The best I have found, hands down, is the AI 3 step system from Osage Audio. It uses an enzymatic fluid, cleaning fluid and ultra pure water rinse, I don't purchase the water as I have access to medical-grade reagent water at work. I use one brush and suction tube for each step. The records end up completely quiet, so quiet it will reveal problems in your system you have not heard before. At last count I have around 2000 records in my collection, so cleaning is very important to me.
Cheers,
Shawn
