Chair conformation down If yours looks a little sloppy consider grabbing The Pocket Chemist molecule stencil below to draw quickly draw your chair and boat conformations benzene rings bonding angles perfectly every time. On your model rotate one of the up carbons down and one of the down carbons up.
Chair Conformation Down, All UP carbons in A become DOWN carbons in B and all DOWN carbons in A become UP carbons in B. The half chair is a twisted form of the chair conformation in which 5 of the carbon atoms are the same plane. This chair-chair interconversion that leads to the generation of two equivalent energy forms is known as ring flipping.

An alternate strategy is to draw a slanted V shape first then add the parallel lines in an opposite direction. Then C-4 can flip down. But notice what has happened to the hydrogens. Any axial is equivalent to any other axial position. To draw the chair flip conformation you have to redraw the ring as its mirror image.

The chair conformation has alternating axial up axial down so once you have that single axial substituent move on to. On your model rotate one of the up carbons down and one of the down carbons up. The boat conformation comes from partial C-C bond rotations only flipping one carbon up to convert the chair to a boat of the chair conformation and all the carbons still have 1095º bond angles so there are no angle strains. However the hydrogens on the base of the boat are all in eclipsed. All that matters is whether it is axial or equatorial.
