Much has been said with regards to table saws and tuning.
This past weekend, I installed a machined pulley and link belt kit from Hartville Tool on a Delta Contractor Saw. I'm not associated with the company or product, wanted to offer them a shameless plug.
While the saw has always been OK; how good can this kit be and can it really make a differnece?
I must admit changing both pulleys and the belt made the saw perform at it's best-ever. I re-sawed 1 X 4 inch Oak on 2 passes. With the saw blade operating at additional RPM's than from the factory (resized pulleys) and the smoothness of the link belt, WOW what a clean smooth cut. Using the same blade as before the upgrade, cross cuts are smooth as glass. If you are considering an upgrade, for $50 bucks I would highly recommend this kit.
Of course YMMV, but I think you'll be pleased!
