Building a cross cut sled for your table saw is almost a like woodworkers right of passage.
There are plenty of videos out there showing you how to build the ultimate one but in this video I hope to show you that you can build them at any budget and scale up the features as you can afford.

*Calculations*

Error per unit or EPU (mm or inch)
((A - B) / 4) / Length = EPU

EPU x distance from pivot = total distance to move the fence

positive (+) number = move the fence away from yourself
negative (-) = move the fence towards yourself
