    Default Just a little tip about board thickness

    I wanted to pass this along. I made two sets of coasters with team logos. I made these out of shorter material, so I used rails on the sides to meet the 7 inch rule.

    The first set was made from 1/2" thick material. Although I didn't notice it until spraying with urethane, but there is a gradual ridge which I attributed to the point where the leading edge of the board got under the forward roller.

    The second set was made from 5/8" material, and there is no ridge.

    Apparently, there is just enough flex in the thinner board that it must be raised up a little when the board is not under the roller. The thicker material must be a bit more rigid and does not seem to have this problem.

    Just something to keep in mind.

    Good observation...
    Favorite Saying.... "It's ALL About the Brass Roller"..... And "Use MASKING TAPE" for board skipping in the X or breaking bits.

    How wide were the rails? Are you sure the 1/2" board was not warped?

    The rails are about 5/8" wide. I did check the board visually looking down the board. I attach the rails with carpet tape, but have always done this. I put a strip of tape at each end of the board edge and in the center. Then I clamp rails in place really tight, and let it set at least overnight.

    It just seems odd that this only occurred on the 1/2" stock.
