So, after doing the overnight load a few minutes ago, I glanced over to the stove to see if the air needed to be adjusted, and this is what I saw........ If you can get past the flash, notice anything amiss? The front tube screw stripped the first time I took it out to clean the pipes, and hasn't been real solid since. Tried putting in a slightly larger screw, but it wasn't, so that didn't work. Anyway, with the welders gloves on, I dang near burned my finger grabbing the tube, and pliers aren't going to work, so it looks like it'll have to stay that way until morning. I must have hit the tube putting in the last couple fillers at the top and not noticed. Funny though, it's still burning quite well, and secondaries look pretty normal.
Not quite sure yet. Hard to work on it when it's toasty like that. I'll probably look for a larger self tapping screw in the morning. Still some jets of flame coming from the holes in that tube, but they're kind of lazy and pointing toward the top instead of forward/down.
Maybe put a heli-coil and a stainless 1/4-20 bolt or some stainless strapping if the self tapper doesn't do it? Never a good feeling with a half broke stove and a box full of wood!
You'll get it fixed up.... It's all about finding just the right screw/threads. Always can tap it out in the spring if needed..
Screws should be stainless steel even a straight steel pin will work that can be inserted in the screw hole- slip fit as it does not need to be torqued tight. now if you broke the screw off so that the hole is plugged that is going to be a bit of work, as you need to get the residual piece out. One of those left handed drill type screw extractors might work. it is a pretty small screw in dia. some care must be taken.
Just retap for the next size larger screw. Shouldn't take to long to fix that up but my guess is that tube being out is going to affect how the stove burned last night.
Well, gooder news. I got the tube reinserted this morning, with a new screw.......wow, that just sounds all kindsa' wrong.....and the stove didn't melt or anything overnight. I put in yet another 3/4" selftapper and it's loose yet grabbed just as the head hit the bracket. It will hold until spring or whenever I can let the stove go cold enough to fix. Knowing me, I'll put on one of those suits that are used to go down into volcanoes and have at it.......or not, and just do it.
Had to run uptown for a couple water shutoffs, so I got a couple different types of screws to try while there. They look slightly larger.
Nothing real serious there Dave but I can imagine what you were like when you noticed it. Not a good feeling at all.
