Scotchbrite Wheel/Mar-Hyde Hint

Did not accomplish any work on the rudder on Saturday, as Renee and I went to Chicago-O'Hare to pick up Heather and Brendan. Blizzard conditions during the drive to and then back home on I-88. Left at 2PM, arrived home at 11PM.

Wanted to pass this tip. My scotchbrite wheel in the bench grinder had developed two fairly deep grooves making edge finishing a bit difficult. To true up the wheel, a belt sander with 80 grit paper held against the running scotchbrite wheel trued the wheel and eliminated the grooves in about 1 minute. Much better than using an old file, and, one does not have to worry about depositing a dis-similar metal in the scotchbrite wheel. The same will work with the 1" wheel in the die grinder.

Also ordered a quart of Mar-Hyde self etching primer. Have the rattle can variety but not the paint can version. Should be much easier to use during the winter months. I'm going to give it a try to prime the mating surfaces. Have been using a small throw away foam brush.
