Thanks, Seb. I have not built up a bike in over 40 years. Seems to be going well, so far. Test rides next week after a new, temporary chain arrives and the pads for the BR-M525 front brake.
I am still unsettled about the gearing. Many talk about 26's on 20Tx36T so I may start, there. I have a feeling it may be a tad tall for my tastes so I may go with a 22T then I can cut it for 20T if needed. Probably go with an elliptical 32T up front, eventually.
