I tried it once ,thats when you see what the blade flex will do to you ,really tough waiting for the frt.to back flex to catch up and be straight at turns ,the center is always lagging ,then you really get to see how much ,side flex you are dealing with ,two different woods adds a new dimention as the grain will also add more problems to the mix ,You are able to see all the ,normally unseen effects of small thin blade trying to eat it's way thru thick dense stock .expensive lesson but if you really look at all the pieces you will get a real understanding of the forces and effects of scrolling ,and is helpful when cutting thinner stock and how important smooth easy even feed is without any extra side pressure ,Thats the smooth easy control I keep refering to .I would reccomend everybody cutting a scrap piece of 2x4 or 2x6 just to personally see how much normal unseen force they are using and the effect it has ,makes a believer out of you fast,then you can see what you are doing ,and go about correcting any force issue have ,tight turns ,even curves ,really show what's going on that you never saw before ! When you consider all that it was an excellent learning experience ! It cost you some expensive wood but I'll bet it will save you a lot in the future and improve your technic ,and the quality of you work ,far beyond what you may think right now !IMHO
