You can buy the clamps that fasten onto iron plumbing pipe. Dad invested in about 6 sets of these and I like them. You just cut the pipe the length you need the clamps. They can be removed and fastened to longer pipes when needed.
I have top of the line Cast Iron Sears Craftsman table saw with the Biesemeyer fence clone. Sears version of it. I modified it to take a 39.5 inch cut on the right. Since cabinet bases are 35.25 high, this is now perfect. The pulley on the motor has been removed and replaced with the next size DOWN to increase RPM's. All my saw blades are rated at 5900 RPM or better and the saw is now at 5200 RPM, the same as a Powermatic. Cuts much better and smoother.
I have a 6" Jet Jointer I use to true boards that are bowed. A Jet 14" Band saw. Lowes used to sell these which is how I got them. I have a Delta 10" Radial Arm that I'm extremely disappointed in. I can't keep it true and square. I'm seriously considering going back to a Sears since their power tools have gotten exponentially better.
Of course, I have tons of specialty wood working tools which include an impressive collection of planes that my wife's grandfather found in a dumpster. I restored them and they are in use.
I have a dovetail jig. Never use it. probably not that I never will but I just build cabinets and I see no value in the extra effort of dovetail drawers. Maybe if I move into high quality furniture, I'll dust it off.
My best worktable buy was a rolling bench with tool drawers and cabinet I got at Sam's. I'm going to invest in even more of these since I like the look and mobility.
I, of course, have air finish nailers that I value in clean cabinet work. Also have a B&D finish nailer cordless 14.4 V that does an amazing job.
Of course, last but certainly not least and a MUST if you get into wood work and that is Irwin Quick Clamps. Get about 10 of these. 6 small and 4 large. You'll thank me later.
* These are not pics of my actual tools but they look exactly like these.
