Both my Dad & I in turn had a jointer long before we had a planer.
If your only doing something like face frames & narrow stock to be glued up you can rip close to size on the table-saw & joint one side & one edge of your stock run the jointed piece through your table-saw with the jointed side & edge against the fence bringing it down close to size say 1/32-1/16 from finished size then back to the jointer to take it down to finished size. The only time I can see that you would need to jury rig something for the planer is if your material was wider than your joiter or taller the you could re-saw on your table-saw then again if you have a good band-saw it could help you out too.
