I didn't do a huge amount on the build this weekend, yesterday (Saturday) I cleaned up a slightly raised area of the concrete floor in one corner where one of the bottom plates of my timber frame will sit. I used the angle grinder with a concrete cup tool attached to remove the bump. This removed the area pretty easy but created a massive amount of dust which filled the room in seconds and I had to do this in short bursts to allow the dust to settle or disperse.
After doing this I cut and attached some timber to fill a gap between the roof and the top of the left hand wall of the adjoining outbuilding. There are still a few small gaps that I'll need to fill later.
I didn't do any actual work today (Sunday) except to spend a bit of time checking the dimensioning of my timber frame drawings before commencing the construction stage. I spent the morning and early afternoon with the family and went Go-Karting in the evening, I'm no Jenson Button but I held my own! Great fun by the way if haven't already done this - I went here: http://www.angliakarting.com for their monthly open GP race.
