Had a day of DIY today. Replaced the handles on one door and took the handles and latch off a second. As parts of the latch came away while taking the handles off ended up spending time chiseling out the hole in the door to fit a new one. Luckily I've caught it before this happens again!
Almost there only need to get another couple of centimetres of the latch into the door, a job for tomorrow. Also braved a trip to B&Q to pick a couple of bits up.
