we bought a house last October, needed some work done, nothing major, a bit of redecorating etc. My tool collection pretty much tripled since, B&Q couldn`t send me enough money off vouchers and all the sales guys know me a bit too well in the local screwfix.
Before my little bosch cordless screwdriver was the only powertool I had, now I have a bosch multitool (very useful!!), heatgun, hammer drill, dewalt circular saw, bench grinder, and I soon getting a jigsaw too. I like a bit of woodworking.
My bike specific tool collection is on par with an average bikeshop`s, plus now I have a big enough drive and garage I started to work on my car, meaning I will need a 1/2″ socket set, bigger spanners, possibly an impact driver etc.
I usually buy the next tool when I can`t do a job without it. Getting something that you *might need is a waste of money. I have a blue bosch rotary polisher that the OH bought me for christmas. It is a fantastic piece of equipment, but almost 8 months later I have yet to take it out of the box.
