We will be having a No. 11 work session this coming week, August 2, 3, and 4. All who are interested are welcome to join us at Sheepscot. We usually start around 9.
The primary task will be to continue reaming the rivet holes in the rear frame pieces. Right now the frame is assembled with bolts and we have carefully adjusted the alignment of the pieces so the overall dimensions of the frame assembly are in spec. To preserve this exact position of all the pieces, the process is to remove one of the bolts that is holding two or more frame pieces together, match ream that hole to a precise diameter, insert a precision bushing and bolt it through the bushing to hold the pieces in alignment, then repeat for another hole in that assembly.
Once two holes in a joint are reamed and bolted, the remaining holes can be reamed.
When we have all the rivet holes reamed, the frame can be disassembled. The precision bushings and reamed holes will guarantee the alignment of the frame and proper fit of the rivets when the rivets are set.
After all the holes have been reamed, final assembly of the rear frame can begin.
