T Ambrosini Posted June 17, 2020 Author Share #26 Posted June 17, 2020 The project continues... I have completed the treadle. The whole thing was created with modern materials based on exacting measurements taken from a few original treadles (the originals were all the same, within 1/16 of an inch). First, the base plate had to be made. It's 3/16 x 2 inch steel with legs bent and shaped.... Link to comment Share on other sites More sharing options...

T Ambrosini Posted June 17, 2020 Author Share #31 Posted June 17, 2020 The frame yoke was attached to the arms with 5/8 inch bolts x 2 on each side. A 14 x 18 x 3/16 inch section of diamond plate was then welded into place. The assembly was painted and looks very much like an original item.

T Ambrosini Posted July 6, 2021 Author Share #34 Posted July 6, 2021 Bring this back to the surface. Battery Townsley had been closed for roughly 16 months due to the pandemic. We finally got the "go ahead" to resume basic maintenance operations this past March and, at long last, opened again for guided tours on the 4th of July. In the days leading up to the 4th, we spent time cleaning the battery, painting out graffiti that had appeared on the exterior walls, and (FINALLY!) installed the major components of the airlock. While a little bit of tweaking and cosmetic work needs t be done yet, the work is very near complete. Link to comment Share on other sites More sharing options...
