How do you politely refuse a pony hoof repair? I just claim my tool belt is at the dry cleaners.

Yeah but Caseyblack saying it's fine for a one off job misses the point... time is the real cost. Even on a short job, that pump dying meant a whole week of lost work. The budget doesn't matter if the machine is just sitting there broken. Saving a few bucks upfront can wreck your whole schedule.

Totally get why @nancy_kelly called it fussy but man it pays off.

I did that last month and still can't remember the villain's name.

When you said it's a mistake you only make once, that really hits home. But even with a routine like @abbythompson mentioned, using the wrong oil can still cause issues in cold weather. I found that a light machine oil works better than heavy grease when it gets chilly.
