Here's my most memorable moment. When I got seriously interested in making sawdust I got a Delta bench saw. It was fine for a couple years -- my errors and problems were much larger than the Delta. But eventually I *knew* the bench saw was holding me back. I was building things that the bench saw simply couldn't handle. So I cashed in my pop bottles and green stamps and bought the 2nd-from-the-bottom-of-the-line Grizzly contractor saw.
I was excited seting up the the Griz. Its surface was at least 4 times the size of the Delta! I had the space to start the saw with a 1x6" fully on the table in front of the blade! I put on my only carbide blade with its blade stabilizers. I started the saw for the first time and with the miter gate cut thin crosscuts of a scrap pine 2x4". After the end of the 2x4" was trued up I cut thin slice after thin slice off the 2x4. Many of them were almost so thin you could read through them! The Delta had too much vibration to cut slices anywhere near this thin! The Griz was outstanding!
Though I was over 40 years old I put some of the wafer-thin 2x4 slices in a letter to my parents. Maybe they put them on the refrigerater, I don't know... ;-) I recall that I wrote that I would have to spend a lot more $$$ to get a saw that had the accuracy to cut thinner slices from the end of a 2x4".
The Griz contractor saw is of course the prime tool in my small shop. Since I got it I've added other useful tools -- 6" jointer, 13.5" planer, three 1/2" routers, floor drill press, 14" bandsaw with riser, many hand tools and probably 40+ clamps. I have used these tools to make things I'm proud of. I have a "critical mass" of tools -- I can create anything in wood I want to.
Someday I hope to have a shop with a 12" or larger cabinet saw as the primary tool. But no matter how capable the "shop of my dreams" is, I doubt if I can ever have the thrill of the first paper-thin cuts from the end of a 2x4" on my brand new Grizzly.
