It always takes me longer than it should. Got a cold saw project going, can only work on it weekends. I've got a lot of pneumatic fittings, just not the correct ones! Another order to Automation Direct.
Robin has an excellent video on rebuilding spindles.
Having managed to get too old, I have to be really careful about always putting things back. The next problem comes when I need to rearrange things & it isn't where it's always been. Recently got a new roll-around cabinet so I could get it all in drawers, which drawer was that? Haven't labeled them yet because I'm not sure I like the layout yet.
