Heating pad for epoxy resin

When I have time I like to get down to the workshop as often as possible. I use the term advisedly as my wife would prefer that her car was in the garage, er workshop. That said although it is under the house and not as cold as it could hardly be called toasty in the winter. I do have a selection of heaters and these help a little but do little more than take the chill off when I am actually in there and although I tend to stay warm enough by a combination of heaters and work this is not good for epoxy resins which is a material that I tend to use a fair amount. If the part is small that I am working on then I tend to move it into the basement which is warmer to allow the adhesive to set up, larger sections and projects that cannot be easily moved to tend to be put off until the warmer weather if at all possible. Although the workshop never gets down to freezing which is bad for epoxy the adhesive if very cold is very thixotropic and hard to pump out of the containers. For consistent mixing and to make it easier to handle it pays to keep the unmixed epoxy at consistent warm temperature. I have seen all sorts ideas from using an old fridge or a wooden insulated box with a low wattage light bulb inside which provides sufficient heat to keep the epoxy at a good consistent workable temperature. But I have found a better way, now I just keep the containers of resin and hardener sitting on top of a heating pad. No complicated boxes to build or old fridges to find room for. Turned down to the minim temperature it works a treat. To stop the pad from getting covered in epoxy drips and other crap I keep the pad in a thick plastic bag. The other thing that you can do with the pad that I never thought of is that you can actually move it and assuming that the part I am gluing up is not too large I can actually set down the glued component down on it where the heat will make the epoxy cure nicely with no amine blush. The heating pad that I use cost $15 at Walgreens.
