Hi I refinishing a cheapo tri star with a wonderful piece of wood. I'm working with tung oil from homer Formbys.

I'm use in 150 and 320 grit to sand the wood before the tung oil. I also have 600 grit for between coats. Any advice on grits for sanding through the process?
Thnks
Dan

  You dont really need to apply several coats unless you see some light spots. If you want to sand lightly to give it tooth use the lightest paper grit you can find.

  Get some "FINE" steel wool for the between coats.

  I would thin the tung oil with mineral spirits to prevent buildup on the wood.
  
  After the first coat, I would use #00 steel wool. All coats after that, I'd only use #0000 steel wool. I'd also use the #0000 after the final coat to cut the gloss.

  Advice?
  
  -Sand WITH the grain. This is actually more important than which exact grits you go through. If sand across the grain, you may leave scratches that aren't readily visible until after the finish is applied. . .(go ahead, ask me how how I know [:(] ).
  
  -Sand all the wood, then repeat with progressively finer grits of sandpaper. I'd end on the wood with 600 grit (not less. . .think "babies bottom" [:D]).
  
  -Apply oil. You can do it with a soft cloth if the oil is thinned a bit. Thinning it out also helps prevent drippy areas and allows individual coats to dry faster. More thin coats beats fewer thick ones. Tung oil dries pretty slowly; leave a day to dry in between coats.
  
  -Once you're done with the first coat or two, go to fine steel wool in between coats.
  
  -How many coats you need is up to you. There isn't really a "right" answer, its a question of how "deep" you want the finish to look.
