If there was one power tool I would never want to live without, apart from the one in my jeans, it would be my router. Amazingly versatile.
My power tool of choice would be a lump hammer.
Those exotic woods can play havoc, my uncle laid a floor made out of some sort of asian hardwood...it looked beautiful but he hadn't left the wood in the house for long enough to acclimatise, along came winter and the whole thing tore itself apart.
Strange that your floor has been down a while though, usually things bed in. I'm suspecting water leak but i'm probably wrong.
I found two sources of leak, laminate in the kitchen was never a good idea, so that came up and the other area is I suspect a bridged damp course in the corner where a lot of damp is, outside the damp course is only an inch above the ground. This flat has always been known as the dampest of the lot maybe that is the cause as this place is built on sloping ground my flat is the lowest to the ground. Other than that I have suspected for a while the damp course has failed because I used to do damp coursing for a living and there is some things I recognise, but the DC is pitch not very usual for a building built in the mid eighties.
But repairs of power tools, I will repair if I can rather than replace, as my family were very much make do and mend, cash was tight when I was a kid, but the Reader's Digest Repair Manual was my bible when I was young, I learned early. But in the power tool repair industry, industry discounts made repairs viable even with the labour cost per hour. Diy machines because of their cheaper initial purchase cost, often it was not worth the repair as the labour cost of £25 an hour usually killed the job, but I used to quote up to half the replacement cost of a replacement machine and offer a replacement for comparison. Diy'ers were a pain really, because the estimate was free, so it took time to find the cause of the fault before quoting. But when I did it professionally, £35 k profit per year was usual, my wages less than half that, so there is a business there if you can get the discounts from the parts suppliers.
Brushes are easy, even if you can't get the right ones, a bit of emery cloth makes things fit and bearings off to the bearing factor as most use SKF.
