Equipment in the shop.

We have added a new Vertical Mill to our shop from J&L Industrial.

The mill has a 23" x 8" table which is larger than the Mill/Lathe combo below.
A 12 speed drive with a 1 hp motor does the work. Uses R8 colletts or Drill chuck.

The weight of this machine is 300Kg or about 660 lbs.

In making Enigma parts, proper equipment is needed to do the job. The Mill / Lathe Combo is one of several machines aquired for this task. The Mill / Lathe Combo is fitted with a DRO or "Digital Read Out" installed for making accurate parts. It is accurate to .01 mm

The DRO tracks the movement of the carriage perpendicular to the axis of rotation or "Y" axis.

   

Vacuum chamber, the white cylinder with gauge and valves, is used in the plastic part molding process for various Enigma parts.

The chamber is used to evacuate the liquid plastic before mix, and molds before casting Enigma-Replica parts.

Incorporated in this setup is a dryer (desiccant), and for larger parts, a chiller plate (pulls heat away), since the plastic has an exothermic reaction during the cure process. This heat can easily expand minute air bubbles in the plastic which is NOT desirable.

This chamber can hold a 29" Hg vacuum for several minutes, removing any air bubbles trapped in the pre-mixed material.

Molds are generally made with outside (female) and inside (male) halves. This way we capture not only the outside detail but the inside detail as well. It will even capture the wear

Vacuum chamber with "release air" dryer, the small canister on the side. Pulls in dry air to prevent moisture contamination.
The chamber can be used horizontally or vertically.
