I have some raised panels I just ran the profile on my router table and the field is smooth from the planer. In the past I found that using 100 grit left a surface not as smooth as what came out of the planer or off the router table. I am thinking I would start with 120 or 150 grit and for this project I have only been sanding up to 180 grit.
How do you determine what grit to start with? I realize it depends on how rough the surface is but what do you do with stock out of the planer or off the router table? Is there some surface test you do to determine the starting grit or is the rule always start with a minimum of 100 grit?
Thanks
