The replacement Zenith Piston install can sometimes be a bit tough on older drops.
The brass interior where the piston Drop slams up and down all day takes a beating! So this can cause the brass around the drop housing to swell, making it uneven and hard to get the new piston in and out.
When I rebuild the drops here, I have a Cylinder HONE I use on those older to make the new piston fit properly and slide smooth again.
Other parts to Inspect
Saves your hand if table drops unexpectedly when your turning the knob. It allows the tension handle to flex down not mashing your hand. The older knobs were a FIXED piece of steel
Also check the bolts in the drop cocking handle and the cocking latch (see pic links below).
Some of the old tables had roll pins in the handles that break and the cocking latch breaks often also. Zenith MFG did NOT use hardened bolts to secure the handles like they do now. If your table has regular screws, update them to the hardened bolts before they break.
