That wouldnt really be ideal for what you want it for like skimming flat faces you turn it by hand you wouldnt really get a good uniform surface finish by hand you would need a machine with power feed imo, something like an old bridgeport would be good but you would probs be looking at double the price of that one you put the link up for possably more, ive been out of the trade for a few years now so lost touch with machine prices etc.

*edit* looking again that ebay link you put up might have power feed its hard to tell really another thing to concider is will the machine be big enough to have enough travel to skim things like cam covers in a single pass.
