Really interesting and helpful thread. I am looking to buy my first table saw or saw bench. It will have to be on the small size due to my limited workshop space. I only came across the issue of different mitre slots earlier this week as I was doing my research. Agree with others that this is really frustrating!
I like Record machinery and have been tempted by the TS 250C-PK/A table saw. But I now note on this thread that the mitre a lot is 12mm, not the “standard” 19mm. Unless I can think of a way to get round this, eg to enable me to extend the cross cutting capacity, I will probably have to look at alternatives. Anyone tried the Charnwood W629? And if so, what are the mitre slot sizes? I may also post this question on a new thread.
