For an oil finish, I would suggest the following for the best results. This is not my process, I found it online from a custom furniture builder John Paquay and it produces fantastic results. His original process can be found at:

Here is an abbreviated version of the process that I use.
- Block sand the wood to 240 grit. Wipe down with a tack rag
- Apply the oil for about 30 minutes with one of those cheapy sponge foam brushes. Keep going over and over the wood to allow the oil to really soak it. Allow to dry (overnight to 2 days probably)
- Apply more oil with a cheapy foam brush to the wood. Using 400 grit wet/dry sandpaper, wet sand the oil into the wood paying particular attention to the end grain. Keep applying oil to keep the wood wet. You're going to build a "slurry" of oil and wood dust that will fill the grain and keep the natural look of the wood. Allow it to sit for 30 minutes or so, then wipe off the excess.
- Allow to dry, may take several days.
- Repeat the above with 600 grit wet/dry sandpaper if desired.
- Allow to dry, will take several days.
- Using Watco Satin Finishing wax, wet sand the wood with the wax using 600 grit wet/dry sandpaper. Allow to dry
- Apply two coats of Howards "Feed-N-Wax" as directed on the bottle (or use any natural bees wax, caranuba wax, etc. just nothing with silicon)
