Here are some of the reagents necessary to carry out an LSD synthesis.
SOCl2
ALCl3
Br2
NaOH
H3O+ (and acid, probably strong like sulfuric)
NaCN (cyanide)

Where are you going to get these reagents?
Not only that at each step in the synthesis you will build up more impurites unless you recrystallize at each step.
and at each step you yield will get smaller and smaller.

plus you need proper solvents and vessles to carry out your reactions at each step. Methanol for instance which causes blindness. There tons of unsafe chemicals necessary.
