Just a reminder for periodic preventive maintenance if you haven't done it recently.
Regarding lubing the blade elevation mechanism, Loring offered the following a while back:
My 21829 has been in use for 5 years now, and just this past week, blade elevation began to feel unusually tight. I've read about it over the years but never had an issue, but knew I needed to address quickly hopefully to forestall further wear in the aluminum threads.
Dry lube or candle wax seems to be favored - After cleaning out some minor dust deposits, I used paste wax (only thing on hand) on the parts mentioned by Loring, ran the mechanism up and down, and applied again - now moving freely like new again.
