On August 31 and September 1-3, several members of the No. 11 Project group worked at Sheepscot flanging boiler components for both No. 10 and No. 11. Straight flanging was done on the backhead and the throat sheet for No. 11 and the throat sheet for No. 10.
Here, Wayne Laepple (center) and Jason Lamontagne (left) are positioning the first sheet for bending in the flanger.
Fortunately, these bends were all straight bends so no heating of the sheets was necessary. Gordon Cook (far right) and Rick Sisson (not pictured) devised a stop that allowed us to make the bends at the correct angles. For the first try, a sheet of MDF plyboard was tried. It worked fine for the initial bends, but as we progressed, the force of the flanging operation caused fasteners to elongate the holes in the pltboard. Sections of steel bar stock were successfully substituted and the work continued.
The first attempt to use steel bar as a stop, seen here, was unsuccessful. A second try, bolting the bar directly to the sheet, worked much better.
The next work session will include additional flanging of No. 11’s throat sheet, the more difficult to execute curves. This operation will require heating the sheet to make it pliable. At this time, we expect to do that in early October.
While it may seem like we did not accomplish much at this session, a good deal of time was necessary to lay out the bends to follow the contours of the sheets. The actual forming operations took less than a third of the entire time we worked.
Here, the toggle of the flanger is just beginning to bend the steel for the initial bend.
In other news, the arrival of the “shop annex,” a 12 x 24 foot structure that has been positioned adjacent to the shop, was followed by the installation of a rack for storage of lengths of flat, angle and round steel stock, steel shelving, and bolt bins. Materials from several locations in the shop have been consolidated into this structure, which will also house various tools and equipment not frequently used that occupied valuable floor space in the shop. Thanks to Brendan Barry, the storage spaces have been set up and lighting has been installed.
Finally, we are pleased to announce that the fund raising for No. 11 continues to move forward. As of today, the total donations raised in 2021 amount to nearly $59,500. At this time, we need just $979 to fully access the $25,000 matching challenge donation received during the spring.
