Unpopular opinion: Isopropyl alcohol might be doing more harm than good on old shutters

I had been cleaning sticky shutter blades with 99% isopropyl for years. Then last month I tackled a 1950s Mamiya and the alcohol actually made the blades curl up. A vintage repair guy told me those old lubricants dissolve and expand into the gaps. Now I'm split between continuing with alcohol for newer stuff and switching to Ronsonol lighter fluid for anything pre-1970. What do you guys use on really old shutters without wrecking them?

Stared at Jupiter for 3 years before I realized my finder scope was off

I kept wondering why I could never center planets in my eyepiece. Frustrating. Then during a clear night in January I pointed my scope at the Pleiades. The finder showed a completely different spot in the sky. That's when it clicked. I had been fighting a misaligned finder scope for over three years. Has anyone else wasted that much time on such a simple fix?

My bank's mobile app killed my checkbook habit

Used to write checks for rent every month. Landlord was old school. Needed paper. Then my bank updated their app in 2022. Now I use Zelle or bill pay from my phone. Takes 90 seconds instead of driving to the mailbox. Anyone else ditch paper checks completely or am I the only one?

My sister told me my gifts always felt like last-minute afterthoughts

She said I'd grab something random off a shelf instead of thinking about what she actually likes. Now I keep a running note on my phone with little things she mentions during the year, and my birthday gift for her last month was a vintage cookbook she'd mentioned back in June.

Showerthought: I watched a brand new turbocharger eat itself on a dyno run in Tacoma

We were doing a final test on a rebuilt 6.7 Powerstroke, everything looked perfect. On the third pull, it made a sound like a bag of bolts in a blender. The wastegate actuator rod had snapped clean off, letting the turbo overspin until the compressor wheel touched the housing. We shut it down, but the damage was done. Anyone ever have a brand new part fail that catastrophically right out of the box?

My grocery budget finally dropped under $300 a month for my family of three

I've been tracking every dollar at Kroger for six months and this week's total was $287. I switched to mostly store brands and started planning meals around sales flyers. Has anyone else gotten their food costs this low with kids?

Hot take: my new $400 drafting lamp is a total waste of money

I got this fancy LED lamp with a 'true color' setting for my drafting table about three weeks ago. The thing flickered out completely yesterday while I was finishing a set of shop drawings for a client in Denver. I had to finish under my old desk lamp, which honestly gave better light anyway. What's a good, simple lamp that won't die on you mid-job?

Yesterday, a neighbor's homemade chimney repair almost started a blaze.
