It may sound crazy the "slow" would burn, but it does happen with wood when you don't "clear" the chips out quickly enough.
...and if you run a metal cutting blade at the speed of a wood cutting saw, it burns the teeth right off of it. I have seen articles written about sawing like this though. Essentially you burn the teeth down to nubs and "burn" your way through the cut by friction. This is a fire hazard though if the saw has ever cut wood, of ever will again.
As a machinist turned cabinet maker, I can tell you that wood and metal are very different to cut...and very few tools cut both. Heck wood is so picky that it matters what direction you are cutting.

All good points. While I started this thread because I was curious about NEW metal saws, alot have said to convert wood to metal. I am considering this as well. Your post above says your can't run metal blades at wood speeds and visa-versa. I agree, but what I have seen others do and would consider myself is buy a cheap wood version at a garage sale or pawn shop or something and "re-pully" it so that the speeds are slowed down for a metal blade. I have personally seen two craftsman models converted in this way and they work fine for the home shop. I wouldn't be using this on a commercial scale so I could probably get by with it.
None the less, I would still like to find a decent vertical metal saw at a reasonable price, but maybe they just don't exist.
There is always something like
this but I don't have much faith in Northern/Harbor when it comes to tools like this. I think they can be fitted with a horizontal bench.
