Thanks all for your responses , i have learnt a lot.
Intially i have brought a 40T Freud blade as i was limited for what is available in stock as i need to make a start on my project. In the future i will buy a blade based on the information you have all sent. I am still learning how to use my Makita Circular Saw (corded) properly and have made a saw guide to help me with cutting accurately. There will be many more questions as i go through my project and learn the art of woodwork.
