So I'm not new to cubing. I am to this site though so hello! I have several different cubes I can solve through beginner methods. I am having difficulties solving my barrel cube though. I try to solve it beginner method LBL but whenever I get to the last layer it seems the middle edge pieces are always standing up in the wrong orientation. Algorithm to fix these please?
3x3 barrel help please

It sounds like you have OLL parity to fix. (some e-layer edges are flipped, but you can't tell)
Try this 8 move alg to flip the UR edge, then do normal OLL after that.
(E R)4
If you get PLL parity (i.e. corners/edges are in positions not possible on a standard 3x3)
This can fix it:
R L U2 R' L'
-= Solvador Cubi

Can you flip this edge on a regular 3x3? Then you can also flip a middle layer edge on the barrel 3x3 and you get an even number of flipped edges on the top layer.
I do it this way: (R U R' U' F' U' F) U' (R U R' U' F' U' F)
(move it to the top, reposition with U', bringing it back again)

For the other case (PLL parity) Sovadors alg is great on a 10 color barrel.
What you have to do if you don't know the alg: Switch 2 slots. They can be next to each other or diagonal (as R L U2 R' L') does.
If you have the 6 color barrel, you have to switch all slots and put the white-green corner on the other side of the white-green edge (and of course the other colors, too).
