I generally don't get involved in this sort of debate and reasoning. But I thought I would stick my foot in my mouth this time.
There are many safer and quicker, not to mention more accurate, ways of cutting dados, it makes me wonder why people here in the US still use dado stacks anyway.
If I were a commercial shop again, through dados would be cut on the radial arm saw, stopped dados using guides and routers. But then, I don't like dados anyway.
In my single person shop, they were cut using the Rat and or by hand. Except in built-ins where there were typically enough to do using a guided router. Bespoke furniture, if you can get the work, isn't the same type of race to get done and what few dados there are in much of the work are easy enough and fast enough to do so by hand or router.
As to importing of machinery? Seems a hassle to me. Each country makes comparable products or has appropriate models readily available. While I think the Wadkins is a really cool looking tablesaw, unless I was financially and mentally prepared for what that means to import one and make it work here why go through the trouble. At least from the perspective of wanting it to actually work with, and not as a hobby to restore and prepare for work.
Well, back to work in my workshop, devoid of a tablesaw now anyway.
Take care, Mike
