Chelonian Posted October 12, 2018 Share Posted October 12, 2018 Hi, first post here. I recently purchased a Champion 400 forge blower for a very good price (60$!). It is in fairly good condition, except for the phosphor bronze helical cut gear. The teeth have worn extremely thin, and I worry that it will not last much longer. My guess is that it was run without oil for a long time since it was completely dry when I got it. All the other gears look fine, it's just the phosphor bronze one that's worn. My questions are: How long might it last if I keep it well cleaned and oiled? Is there a way to adjust the mesh between the gears to make it wear less? If it does wear through and stop working, is there any way to get a replacement? Any and all help appreciated! Thanks! Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted October 12, 2018 Share Posted October 12, 2018 Welcome to IFI... That gear looks like it's on it's last legs. No telling how much longer it will last if you start it gently, one hard crank could strip it out. As far as I know there are no new replacements. I would keep my eye out for another, that has a good gear but other issues that make it reasonable in price. Quote Link to comment Share on other sites More sharing options...
Chelonian Posted October 12, 2018 Author Share Posted October 12, 2018 Thanks, that's pretty sad to hear. Shame someone just didn't bother giving it a few drops of oil now and then. Would there be some way to braze on a new layer of bronze and cut new teeth into it? Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted October 12, 2018 Share Posted October 12, 2018 It could be done, however I read in one thread to do that by a machine shop, the cost would be around $1,000 U.S. Quote Link to comment Share on other sites More sharing options...
Frosty Posted October 12, 2018 Share Posted October 12, 2018 Don't hold it against a previous owner, things have a lifespan, a few drops of oil won't make one last forever. I'm afraid mine may be dead, it got rough, then very rough and hardly turns now, took a couple hours. I'm hoping a keeper or bushing slipped and I can revive it. If not I'll have to come up with something else. If I have a gear worn like yours I may rig a tig welder from my little wire feed, buy a bottle of argon, appropriate rod and see about building it up and cleaning it. That's just a thought for now, I haven't opened it up and evaluated it. I'm not in a hurry though I'm mostly a propane forge guy. Having one machined on the other hand isn't in the cards for me at all, I could buy several outside and ship them north for less money. Frosty The Lucky.
