I also did a bit of sanding on two of the bars of the sectional beam, and the top bar of the beater. There are still two more bars to do for the sectional beam. They will all get a couple coats of wipe-on polyurethane varnish to protect the wood and to make it a little easier to clean in the future.
Bob found a supplier of square head bolts called Blacksmith Bolt and Rivet Supply in Portland, Oregon, so I may replace some of the overly rusty ones. Here is a link:

We thought the cost of the 5/16"-18x2 1/2" bolts, at $.27 each with a minimum order of 10 was quite reasonable. They have a black oxide coating, so they won't be bright and shiny.
Bedtime. My thumb, arms and shoulders are sore and tired.
