The good news: I worked out how to change my saw blade and cut a couple of window holes in the middle of the back wall.
The bad news: I'm still not crash hot as cutting straight with my scroll saw, so unless I feel the sudden need to channel Hudertwasser, there will be some packing and sanding in my future. And I decided the only sensible thing to do to avert further catastrophe is to cut the weatherboard using a knife and ruler.The good news: I did another trial fit. I'm feeling hopeful.
The bad news: I miscalculated the length of the middle wall when I cut it. So it'll be headng back to the saw.
The good news: I'm pretty certain I know what to do next.
The bad news: that bit of MDF I picked up from Bunnings for the front looks like it's too high. There will be more wonky cuts in my near future...#HBSCreatinContest2015
