I am curious as to what other are using for fans/blowers for pushing air into forges...   I have currently a 12v dc Datsun  heater blower  powered by a 12v battery charger.. And external damper on inlet..   http://www.iforgeiron.com/topic/31104-first-time-forge-build/#   And have found a 115v ac fan off back of dish washer and am in process of adapting it (because existing mount is almost non existent)  and developing a blast gate for inlet to tuyere to be used with what ever fan I end up
