This last weekend was most productive, also as we had a very nice crew hammering down staybolts and cleaning out holes in the throatsheet preparing them for welding. Betsy Zonnerville, Bob & Kevin Reihl, Mike Wahl, John Sorrel, Doug Crary, Dave & Bryon Schumacher, Al Hill, Chris Thompson and Kelly Bauman were there to lend a hand. Many staybolts were hammered down and the telltale holes were drilled clear to finish part of the firebox repairs. The staybolts are what hold the flat steel sheets of the firebox together against the pressure of the steam and water in the boiler. The throatsheet is the very front of the firebox that helps make the transition from the rectangular shape to the cylindrical shape of the barrel. The staybolt holes there are being filled with weld and will be drilled out to be threaded when the new rear tubesheet is fitted to the inside of the firebox/boiler. Once again, saying thanks doesn’t seem adequate but WE ARE DOING THIS!
