  • Bowl Sanding

    I have decided to take up making scroll saw bowls. I have Carole's books and so am ready to start but have a few questions.

    I would like to know your recommendations on the sanding equipment needed.

    My thought was that I would get the Guinevere inflatable system but am not sure about the motor they sell. I have 2 drill presses and wonder if I can use the flexible extension with my drill press with success. I have limited bench space too.

    Also, does any one use the inflatable sanders on their lathe with a Jacobs chuck and if so what speed do they sand at?



    PS: I am in Canada and I have found I can buy the equipment from Chipping away and they seem to have all the optional equipment.

    Don, what to get depends on what you already have, since you don't want to spend unnecessarily for things you don't really need.

    You do need a way to sand the inside and outside surfaces. The Guinevere round inflatable is great for the insides, and you can chuck it into your drill press. That way you just need the sander, some sleeves, and the pump. Sanding speed of about 1600 rpm works fine. If you're looking into using a flex shaft, be sure you have a way to secure the bowl or things could get awkward. I use the 2" pad sander for the outside, but what will work best often depends on the shape of the bowl.

    I'm sure other folks have suggestions to add to these, since there are many ways to go about it, but I thought I'd throw out some of mine to start things off.

      The inflatable drums are good for the inside. A spindle sander will also work, but be careful about sanding down the bottom edge. You need it to attach the bottom.... Have also used a sanding mop for final smoothing. Seyco has a 1600 rpm sander with foam-backed drums that also works on the insides. Sanding speed in the range of 1600 seems about right no matter the power source. Some fine detail may be done with something like a Dremel where speeds are higher.

      A 5" random orbit sander does a good job on the outside if your bowls are 3 or 4 rings high and not too many waves.

      Best wishes for success.
