Re: C & S 1008 Update: More Frame Parts and Hardware
| June 21, 2020 07:27PM |
Continuing the status update on C&S 1008 . . . .
More of the frame parts and painted hardware have been attached to the frame; the dead wood and coupler crash bar at the center, end grabs, brake beam brackets, longitudinal tension rods and end washers.
The Miner draft gear cheek plates have been installed on the lower center sills.
Nearly all of the various bolts used to hold the center sills together, and to mount all of the many hardware parts, were made by Richard by machining and threading steel rods of correct diameter and length. This was also the economical way to get square-head bolts for the large and unusual sizes needed. While there was a lot of variation on 1008 and 1006, it seems the common practice was to use a washer, nut and 1/2 thickness spring nut as a lock nut on each frame bolt and mounting bolts for the larger hardware (such as pedestals, springs, cheek plates). Here are the 1/2-thickness custom lock nuts in production in Richard's shop, with the holding fixtures that were used for machining.
We have also fabricated the recreated brake cylinder mounting board. This picture shows the original relic board (badly split and decayed) and the new board made of laminated white oak. The circular indentation for the reservoir was made by a commercial wood shop for us, using a dado blade in a large radial arm saw.
Most recently, the frame tension rods have been brought to final tension and trimmed to length. The center sill bolts and others have been torqued up, and the lock nuts installed (you can see these on the cheek plate photo). The leaf springs are in the shop to get final preloading, based on calculations that show these springs will deflect about 1.5 inches under load. Note the panel track in the next picture that was built under the frame. As things stand today, we are getting ready to raise the frame, attach the pedestals and springs, then roll the C&S wheel sets underneath and bring the frame down onto the journal boxes.
We're expecting to make more assembly progress over the summer and fall. Take care all!
