    Fixing doors that have sprung other way?

    Just had a though, Ain't those clamps cast iron? Am I going to have a hard time spot welding them with regular rods like 6013 or 7018?

    Is Feldon's Calculator really flawed?

    Do you think making the opening larger is needed with my FB design? I guess I could do it, but seems like a lot of work for extra 14% increase in opening size. And I'm a little concerned about how strong my FB is going to end up, the fit up was less than perfect. Thus I'm going to end up with...

    Fixing doors that have sprung other way?

    Thanks, I tried to shape it with a bottle jack with some chain wrapped around the tank. Not so easy to manhandle. I guess I'll need to get my longest pipe clamp and spot weld it to the inside. My "shop" is just a bunch of rudimentary tools outside, makes things more interesting  Am I right...

    Intake styles?

    I kinda figured that, I think I'm going to go with similar configuration, I already cut flat bar of similar thickness of the intake slider to be welded on the door. Then I'll add shims (since there's no gap by design) and bolt on the top frame. I was thinking of using springs instead of shims...

    Is Feldon's Calculator really flawed?

    Yeah, after cutting the plates I though I could've put it even closer to the door. Oh well :-) Still haven't found suitable springs for the pie vent, but that can probably wait. I'll have to get this thing up and running by the end of the week, but springs can wait for later ;-) Going to be a...

    Is Feldon's Calculator really flawed?

    Well, I hope the air will flow. At least for me it's a bit late for a mock-up :-) Here's a pic of how things are looking today: My FB to CC is currently identical what Feldon's recommends for my 109% firebox. I can make it a bit larger, it wouldn't probably hurt, right? The area under my RF...

    Fixing doors that have sprung other way?

    Tried fixing them, some progress got made... But now I found out my tank has sprung outward from the center between the doors! That explains why the doors fitted better on center than sides... You can kinda see that from this pic, look at the two halves of the rf plate, how they slope towards...

    Is Feldon's Calculator really flawed?

    So...Wait.. You'll want your FB to CC opening to be 1.5 times bigger than Feldon's calculator suggests when calculating using 100% sized firebox?

    Firebox to CC opening not quite all the way to the top?

    It's pretty much 100% with calculated right now, it'll be about 114% of calculated if I cut it all the way to the top. Also, I usually run my pit hot and fast at around 300-350F, so maybe a bit oversized opening would be even a good thing?

    Firebox to CC opening not quite all the way to the top?

    Hi, I almost started tacking up my firebox when I realized something. I haven't cut my FB to CC opening all the way up. I did it with cnc plasma beforehand, so there's a rim of around 2/3" on top. Here's a Sketchup model how I cut it: Will this be a problem? I know some hor air could get...

    Intake styles?

    What's the idea of the screws? Do you have springs under them to keep tension on the intake slides? Or are they there just for easy removal?

    Fixing doors that have sprung other way?

    Ya, I'll post some pictures. Got the jack and chain to work (both ways), but now it's a little bit worse :D I'll post some pics after I've had a go at it.

    Fixing doors that have sprung other way?

    Ok, It really looks like my doors have sprung inside from the corners (most gap on the middle) . I tried using a bottle jack, but it was really impossible to get the door to sit "upside down" on it. Any tips? A sledgehammer?
