I built this bowling ball rejuvenator from a dehydrator, igloo cooler, and miscellaneous small parts. dehydrator - $40igloo cooler - $14miscellaneous small parts - $8The temperature will go up to 190 degrees but when de-oiling balls I keep the temperature around 150 degrees. It works great!!!! Let me know what you think, pretty cool isn't it?Mike http://s1316.photobucket.com/user/Mike_Hames/library/?sort=3&page=1
