A manually operated dough press comprising a frame with a base and a housing, an upper platen having a working surface, and a lower platen attached to the base and having a working surface opposed to, substantially parallel to, and spaced from the upper platen working surface. The upper platen is attached to the lower end of a shaft that extends from the housing and mounted for reciprocating motion. A pair of mated interlocking components, one attached to the shaft and one attached to the housing, provide stability for vertical reciprocation. The drive mechanism includes a rack on the shaft interlocking component, a mating pinion fixed to an axle that is part of a handle that an operator uses to raise and lower the upper platen. Counterbalance for the upper platen/shaft is provided by a torsion spring assembly.
