Quick question about headset (lower)
I'm taking the old fork off my mountain bike turned commuter because its suspension mechanism is dead. I have another (somewhat newer) fork laying around which I can use as a replacement.
Is it better to take the lower headset off the old fork and put it on the replacement fork? Or is it easier to buy a new headset (doesn't cost much anyway) and put the lower part on the replacement fork?
(BTW, nothing wrong with the existing headset so far)

I personally fo not replace servicable parts unless upgrading. It msy be prudent to keep the race with the headset..

It depends on the type of lower race
In a typical 1 1/8" headset, the lower race is substantial enough to be removed and re-used. There's a special tool for doing this, but before I had one, I was able to remove them by tapping a thin-bladed screwdriver under the race, working a little at a time from both sides. Sometimes you get lucky and they come off easily, but often it will take a little work.
The other option is to take it to a shop and have them use a lower race puller on it. It's likely to be much cheaper than a new headset.

I typically have to rotate the fork 180-degrees after each hammer blow to the handle of a burly screwdriver, in order to "rock" the tight crown race off of the steerer tube. It takes a while sometimes but they always come off and are reusable unless the bearing track is pitted.

Trick is not gouging the crown. Not that on a computer of age it requires the care of doing the same opetation on an all carbon fork etc.

Are you using the not-quite-ready-for-prime-time speech recognition? Or just the good old buggy auto-correct?

Some manufacturers (eg FSA, Hope) use a split crown race, which makes it extremely easy to remove and install - only fingers are needed. And if the existing headset is fine, if you can't easily remove the crown race, then depending on the manufacturer, crown races can be purchased separately.
I have one bike where I purchased an additional crown race as I swap between forks - C-F fork for unloaded riding, I swap in a steel fork for touring with front rack and panniers.
