Question about buffing speeds

[jhearn]

On one of the Caswell links I read that the recommended speeds in surface feet is 3500 to 7200. For green compound on stainless (thin car trim panels) using a 10 inch soft, cotton wheel, which would be a better speed: 4300 sf or 8500 sf? In other words, is the 8500 sf too fast for some reason? I wouldn't have thought so but after reading the above recommendation, now I'm not sure.

Yes you would want to use the lower buffing speed to reduce the risk of warping the piece.

The trim I am polishing is from a 1954 car so it is reasonably thick and not too subject to warpage. I thought heat was my friend in polishing so if the piece warmed up a little so much the better. Also, it is a soft cotton wheel so the pressure on the wheel will be minimal. Thanks for the previous post but I guess I'm just amazed that 3400 rpm spindle speed and a 10 inch wheel are too much.

You should be fine then. I use 3450 spindle speed with 6 to 10" buffs and it all works fine for me.
