In the plumbing aisle, you'll also find PVC and rubber 'reducer' couplings that let you connect your vacuum hose to a different-size pipe.
Fill a sturdy cardboard box with sawed-off shipping tubes or scraps of larger PVC pipe. Then use it to store and organize all those short pieces of molding, pipe and dowels.
Quick-Draw Table Saw Accessories
Keep your table saw's miter gauge and push stick within easy reach with a couple of sections of 1-1/2-in. PVC pipe bolted or zip-tied to a convenient spot on the frame under the table. Attach the miter gauge holster using the existing frame bolts, or drill holes in the legs for machine screws. For the push stick holster, we drilled a couple of sets of matching holes about an inch apart on the pipe and tautly zip-tied it to the leg.
