Photo Journal

Although blurry (we need to find a steadier photographer), the 7/8" bar is heated to "yellow" hot in a water cooled induction coil. It takes 51 seconds! The coil is square copper tubing with cooling water flowing through it.

Forging of crown staybolts

Friday, June 28, 2013 by JN

We have been manufacturing new staybolts for the crown of the firebox in the boiler. The first step was preparation of the dies to be used in the forging. Next we cut lengths of 7/8 steel bar which were carried up to Portland for the ends to be forged. Here we see some shots of the forging process.
