The motor nor the mass of the blade has anything to do with it.

I the main concern is the higher tension required for the 3/4” blade and the stress put on the frame and/or bearings of the saw.

A saw with the 6” riser would be even more of a concern.

That said, I have used a 3/4” Woodslicer on my Delta with the riser under full tension for years at a time. I have not noticed any problems at all.

Now that I have a Steel City saw also I put the 3/4” blade on it and use smaller blades on my Delta. I figured that since the Steel City has the quick tension release why not use it.

The wider the blade the straighter your cut.. Imagine cutting with a wire and how that would work.

Also a smaller blade will bow when too much pressure is used making a cut that is curved inside the stock

Imagine laying a full sized sheet of paper flat on a table. Lay one hand flat on each end of the sheet and try to stretch the paper with the heel of your hands the push it together with your finger tips. The paper will bow up between your finger tips. The narrower the sheet the easier it is to bow the paper. The same thing will happen to a smaller blade.
It will bow inside your cut and you won’t know it until you finish your cut.

Blade thickness is not really a factor either. For example the 1/2” and 3/4” woodslicer blade are both .022” thick.
