was gonna sugest what this man said. i did a massive tilling job, about 800 square feet (most of it was stairs ) with my old man in the summer and we borrowd a free standing jobbie with a 10" blade. pissed through everything.

i found the way to stop the end breakign off is to stop about an inch from the end, turn it round and cut the last inch from the other dirrection. do it carefully and itll work everytime.

big saws like we used make it so much easier and quicker, plus if youve got a steady hand you can get curves and corners and stuff perfect!
