I was inspired by Dave Schell several months ago when he posted a thread about his Vicmarc base and bought myself a new Vicmarc VL300 long bed. I got the lathe from Woodworkers Emporium (Christien Brisepierre in Las Vegas - a great guy) and picked it up at SWAT in October. I bought the lathe without a base, motor or controller, got a show discount and brought it back myself, saving shipping. So, I ended up paying about half of what a VS with a base cost (~$5,000), since I already had a 3HP motor and controller from a homemade lathe I built.
The base is made out of 3/4" ply using two torsion boxes (one on the top and one on the bottom), each filled with about 74 pounds of sand. The finished base weighs about 350 pounds and the lathe is another 375 pounds, so it is really stable.
I reprogrammed the controller so that on the 1:1 pulley, I can run from about 100 RPM to 2750 RPM without changing a belt.
This Vicmarc is very well built and a joy to use. I really like the long bed because I can slide the tailstock to the end of the bed and it is out of the way when I hollow. I also don't have holes in my right elbow anymore from the live center.
