I am an owner of a ryobi Bt-3000 table saw with the factory base. I like the table saw, but I don't like the base. The base consists of a set of stamped steel that are bolted together. The frame makes the table saw light weight and more portable. However, because of its construct the saw is more susceptible to vibration when cutting stock.
Generally what I want to perform is to 'bolt down' the table saw and frame to the shop floor. The heavy duty commercial cabinet saws are constructed with a lot of mass. The top is typically constructed from cast iron and the base is made from heavy gauge steel. This effectively anchors the saw to the floor and any vibration from the motor, arbor assembly or saw blade does not allow the table saw to vibrate very much. Granted the more costly undertaker of a package deal and cabinet saws' trunions and arbor assemblies are great balanced.
Vibration is caused by the motor, arbor assembly, and saw blade being out of balance. Even if one of them is ever so slightly out of balance will furnish some amount of vibration. In my plan the biggest contributor to blade vibration is the saw blade. For my main table saw blade, I have switched from a no name brand carbide blade to a Freud 10" 50 tooth blade.
Ok, back to table saw base vibration. There are a join of solutions to minimize the saw vibration. A quick explication is to weight down the frame with some sort of ballast. For the Ryobi Bt-3000 reinforce the base with two 3/4" pieces of plywood. Then stack on top of the plywood ballast, such as paver stones, concrete blocks, or bags of sand. Paver stones are nice because they allow you to operate how much weight you want to stack on the base. The draw back is it can be a lot of pavers to load and unload. Especially if your shop is in the stable and portability is a must. You know, the wife wants to park her car in the stable every night.
Note: Depending on how the table saw frame is designed, you might have to progress the base.
Another option is to cast your own concrete slabs. Depending on how much weight you need three or four slabs should be enough. This translates into fewer amount of ballast to load and unload when the saw needs to be moved.
A third option is to build your own transportable table saw base. When I purchased my Ryobi Bt-3000 table saw it came with the prolongation rails and table. Unfortunately when the prolongation rails are bolted onto the table saw makes the saw much less portable. The base I am planning to build will have retractable wheels, and will be wide adequate to hold the table saw and the prolongation rails permanently mounted to the base. The under the saw and under the prolongation rail will be built out with warehouse cabinets. If I needed I may put further ballast into the base.
Quick tip: Make sure that all of the fasteners on the frame are tight. If any of them are loose the more vibration you will get. Use lock washers, or lock nuts. I like the nylon lock nuts. If you are not planning on taking the frame apart, think using locktite or some other thread locking adhesive.
