hecktic day and I did not inspect a students polyurethane work until several periods later. He did a table top and then leaned it against a wall, upright on end. Apparently he or another student dripped Polyurethane on it or he had a HUGE run and now there is a raised triangular trail four inches long that tapers from 1/2" to 1/4" and then a big solid drop at the end of it.

On my own projects I would sand down to wood and start over. Any better suggestions for fixing the problem?

FYI the top is made from pine, stained walnut, and this is the second or third coat of Poly.

suggest you make sure the drip is really hard. Maybe a week or more. Then use the cabinet scraper like Joe suggests. If not rock-hard-dry it will be like trying to take gum off a shoe. Once hard he can scrape down to an even surface with luck and careful work.

Great so far!! Instead of cab. scrapers we always use sharpened pieces of sheet metal (I have a metal shop also)so that was kinda out the door, but I did try a razor knife blade and it worked great.

The drip was still somewhat soft and the rest was slightly harder. I did have to watch not to dig in too far, but it was relatively easy to just drag the knifeblade along like a scraper and cut the run off. Monday we will 220 the top and recoat.

Thanks.

Let it fully dry and put it through a wide belt sander with a 220 grit belt on it. Barely take off any material.

I passed one of those up at an auction a few years ago. Would have been nice for this though.

I love our 36" wide TimeSaver, we use it as a planer since we do not have one.
