Hi. I recently bought a MacAllister flip over saw from B & Q. Is good for the price and quiet, but I now need to cut mitres in the table saw mode (too long for mitre saw mode) but when you finally get it to 45 degrees (have to shove motor, very inaccurate) the blade leans on the plastic insert. I tried taking it out but the blade then leans on metal not great I think. I have trawled the internet for a MacAllister phone no. B and Q say can take it back, which will be ages and it weighs a ton and I need it, NOW. Would be really grateful if anyone has any advise.................... Thanking you.
