Used excalibur sliding table 40” for $300.00 OBO.
It’s an older model and the sliding table works because I tested it and it slides smoothly.
It does have some wear and it needs some little parts like where it has a little vise grip.
About the only thing I see of significance is the legs which have been cut and re-welded to give it more width but I’m sure new legs can be purchased if you want.
It works just as it is.
