Sometimes it might, but most often it means recycling old junk into a new life as something else or getting used parts to fix something. Scrounging is not often a term used for buying new things to strip down, unless maybe it's scrounging for discontinued stuff or through old stock found in a warehouse and such.
Geuss it could mean alot of things, just depends. Mostly to me it means a trip to a salvage yard
Or an old dump if I find one I can dig through
Hmm, that last one almost applies to my front yard!
