New Information about the CarveTight Spindle

[CarverJerry]

So I take it that the longer screw and the 2 washers is for weight to help balance the spindle better, am I correct thinking this way? I would think they would have preformed a balance test during designing of this. There are ways to get an item perfectly balanced now days.

I worked at a place for DOE where we made centrifuges that were 50 feet long about 2 feet in dia with about a 1/4 wall thickness, they would spin these at a speed of around mach 3. They used a special computer and machine to put weights (small pieces of foil tape) to get this tube perfectly balanced. Of course they spun this thing up inside of a steel case under vacuum and took hours to get it up to speed.

Jerry,

Yes the longer screw and added washers helped improve the balancing of the chuck. It did make a difference.
