Yesterday when I got that CI stove door from the neighbor , I also loaded up his hand cranked forge blower . I've got it pretty much stripped down now and Houston , we have a problem . There are some gears in the drive , straight cut spur gears and one helical ... and the last gear in the train is a small helical and it is badly worn . This gear is machined on the shaft as one piece as far as I can tell , and I'm very doubtful it can be replaced . I'm not sure just how old it is , but he said it was his grandfather's blower from his coal forge - which the guy also has in his shed . Any chance one of you guys has a source for parts for antique forge equipment ? If I can't replace the shaft I guess I have a couple of options : I can very carefully TIG up the teeth and hand fit the gear , or if I can find a gear with the proper pitch and angle I can fab a new shaft . Everything else is just straight replacing screws and machining a couple of bushings .
