I and a couple of my friends have started using toaster ovens for panlubing. Once your cake blocks have been preused and have the holes in the cakes you can load your boolits and warm up your lube. Some of the better ovens have more accurate temp controls and its really important to keep your lube not much more than 200 degrees. My understanding is "overheat your lube and it's no good".
So far it's about a third the time of using the double boiler. Prep and cleanup time is almost none. Just so much easier for me.
I just caution everyone on the temps involved to know your individual toasters controls. Try putting your toaster on warm or 200 degrees with a lead pot temperature probe and compare temps so you're aware of how far off the controls are. You just don't want to overheat your lube.
I hope to hear of peoples experiences with this method.
Thanks
