Hi I'm back,
I made a zero clearance piece for my saw table today, fitted an Olson No 5 reverse tooth blade and had a great day.
I think the project is a bit too advanced for me but it was fun trying, I will leave it for later.
I have purchased a couple of books and will work my way through them, hopefully learning what I need as I go.
I have received a great deal of help and advice from this forum and I would like to thank you all, no doubt I will be back with some more stupid questions.
