!3mm and 10mm aluminium channel on sale at my local hardware store, £3 a metre. Being 1.2mm thick, they are quite sturdy and nest nicely inside each other making them ideal for homemade small pan grippers. So, cutting a 5mm slot 5mm from the end of the thinner channel and drilling a 3mm hole near the end of the larger channel, with a small amount of filing I get a nice fit on the rims of some stainless steel pans I have with no handles. Then cutting a recess in the top of the larger channel so that the channels can pivot, and drilling a 3mm hole through both channels for a pivot bar, the gripper is complete. Here it is before cleaning the edges. Fits the pans perfectly and drops inside the smallest pan for storage. Also can be made to fit Globetrotter pans and should fit almost any small pan with or without a rim. You can of course drill holes to make it lighter, but it is only 18gms for a 10cm long gripper. Cost per gripper 60p.
