Shop progress is slow but advancing. Have new band saw in place, one workbench built and another beginning. All interior ceiling and walls painted with multiple coats of Behr white gloss paint. Nearly 20 amps of lighting via T5HO, T8, and T12 celing fixtures. Central vac system and ducting is done and works well. I read that an 80 year old person needs three times the lumens per square foot of floor area as does a young person.
