Background. The county approved the addition as completed. They have to come back and fix a few things, no biggy. The big room is 12 x 20. The workshop is 8 x 12 and I expect to use part of that for turning trains and storage.
At the moment I have the table I built several years ago. The frame is made of 2 x 4s. There are three rectangular stands that have casters on the bottom and are connected by 8' 2 x 4s.This forms a 4 x 8 stand. On top of that goes a platform constructed of 2 x 4s and about 3/4" plywood. It's heavy but solid, I can stand on it. I may have overdone it. I had covered it with a piece of indoor outdoor carpet but it really didn't help the that much. After reading numerous posts I sought out something else.
STEICO Natural acoustic wood fiber underlayment 90-sq ft Premium 3 mm Flooring Underlayment
This comes in 3 mm and 6 mm thicknesses. The thing that attracted me is it comes in 2 x 3 foot panels, which is very handy. I may glue them down, a little more research will be needed.
Then a 1/2" or so carpet pad and then Grizzly Grass indoor/outdoor carpet. I have FastTrack, K-line Shadow line (K-line, RMT and O-Line) and I am looking at Gargraves.
Now this temporary and will eventually be used as a test platform and for holiday displays. I can probably get heavy curtains to hang around the platform to suppress any sounds from underneath.
Does this sound like a good plan? Do you think the Steico panels will give what I'm looking for which is quieter running. It is not expensive, $60 for 90 sq ft of the 6 mm.
Of course when I start my "real" layout I will explore more conventional methods but I have not run trains in over 3 years and I really want to get back to running and working on my trains.
