Re: Power tool for sanding toe rail
A Fein MultiMaster (or another company's equivalant) will do the job, but you may not save yourself much time. I usually reach for my Fein first when tackling projects, but when doing my own caprails I found that the old fashioned methods were in fact faster and yielded better results.
I'm with SJB and PP on this one -- combination of a sharp card scraper and where necessary Citrus Strip. If the finish is particularly stubborn, a heat gun will come in handy.
