Overview

This project is the result of my fiancee wanting to have nicely made letterpress invitations to our wedding. Upon looking up the prices for such types of invitations, we were looking at about $900 to $1000 for just 100 invitations. As we started to look into it we realized that we could do this much cheaper on our own. All that was needed was the plates with the design, the ink, and something to press them with. Looking online for others' attempts, we found several where people had simply made them out of wood and were using leverage and their own weight to press them. We decided that we could make something similar with a few improvements, mainly the hydraulic portion to improve how even it is.

Features

Implemented

  • Hydraulic jack for pressing force
  • Made from simple hardware store pieces

Issues

  • The press does not apply pressure to the plate and paper evenly causing portions to not indent into the paper.
    • Possibly increase the hardness of the pressing plates, maybe use a minimum of 1/8" steel
  • The metal piece for the bottle jack to push against is indenting from the pressure causing the pressure to disperse unevenly through the plate.
    • Replace the fence post anchor with something a little bit thicker and more rigid
