Hi Paul, I had a similar problem with my old saw. My cure was to cut a piece of cereal box to the shape of the hole, like a gasket,and plonk the red plastic plate back on top. Oh!!! and WELCOME to the forum Paul, I'm Roy from Scotland. I'm sure you will enjoy yourself here and if you have any questions, just ask and you'll have more answers than you can shake a stick at. Some answers will be sensible, others not quite so . So come on in and enjoy all the wonders you'll see and all the great friends you'll make from just about every corner of the globe. If you need patterns, well, if you don't find anything to your liking, (which I doubt), in the gallery, just ask and one of our magical pattern makers will have you fixed up in jig time. Don't forget to check out the breakfast menus too. ENJOY and take care Paul.
Rob Roy.
