The Craftsman Professional 21833 table saw is a heavy-duty contractor saw -- a quasi-hybrid saw -- with a cast-iron table and minimal vibration. The saw earns high marks from owners for its easy mobility (with retractable casters), good dust collection, 30-inch rip capacity and quiet power. (It can also be wired for 220 voltage to add even more power.) The split blade guard earns mostly good reviews, though one reviewer notes that at certain blade heights the blade is exposed. Reviews say the fence and miter gauge are acceptable for this price range, and their standard T-slots accept upgrades and jigs. Many reviewers mention that assembling the saw can be tricky, especially when it comes to reaching the bolts inside the cabinet for aligning the blade. The main drawback, though, is that quite a few owners report quality control issues, including blades that go out of alignment whenever the blade is raised or lowered. This is not a small problem when trying to repair or exchange a product that weighs nearly 300 pounds. For a longer warranty, consider the nearly identical Ridgid R4512 (*Est. $280) , made by the same manufacturer.

Review: Craftsman Professional 10 in. Contractor Saw (Sears #21833), Contributors to Sears.com
This review of the Craftsman Pro 21833 table saw by a retired electrical engineer praises the saw as a quasi-hybrid, detailing the pros and cons of each component and also noting some tedious assembly issues. He finds a major problem after aligning the blade, however -- noting that changing the blade height or bevel changes the alignment. After the initial 90-day return or refund period, the Craftsman warranty repair requires removing the base and fence and taking the saw to a repair center. Links to other reviews at this site confirm the same problem, due to machining and casting errors on the motor bracket and main trunnion. The author tries some machining to fix the problem, but it's unsuccessful; another reader explains a procedure that got a little closer to correcting it.
Review: Craftsman 218330 10-in. Contractor Table Saw, "Smitty", June 2010
Paul Sikkema reviews Craftsman tools supplied by Sears, and his review of the Craftsman 21833 table saw includes a few comparisons with the Craftsman 22114. The main drawback he notes for the Craftsman 21833 is the assembly process, noting that "the instructions are not the best Sears has written." Also, Sikkema finds the front fence track a little tricky to assemble and align, and the throat plate isn't a standard half-inch thickness. Mainly though, the saw is highlighted as a great value -- solid fence, slots that accept standard accessories and jigs, true riving knife, arbor lock, etc. When a reader asks about the issue with the blade alignment varying as the blade is raised or lowered, Sikkema replies that the saw is designed for accuracy to the nearest eighth of an inch; closer accuracy for fine woodworking requires a hybrid saw with cabinet-mounted trunnions.
Review: Craftsman 10-inch Contractor Table Saw Model 21833 Review, Paul Sikkema, Jan. 25, 2010
This brief, enthusiastic review of the Craftsman 21833 table saw includes some good photos, including a close-up of the split blade guard, which earns kudos here. The review focuses on the saw's value for the price, especially compared with stepping up to a cabinet saw. The saw passes the nickel test for vibration.
Review: Craftsman Professional 10-inch Contractor Saw Model #21833, "Glenn", Nov. 2009
A biomedical engineer and amateur woodworker reviews the Craftsman 21833 here, describing his disappointment with the blade alignment varying when the blade is raised and lowered. Then he embarks on a series of exchanges -- first a crooked fence rail, then a bent miter gauge, then a ruler tape with part of the numbers cut off. At that point, he gives up on this model. He praises the saw's mobile base and 30-inch capacity, but notes that the guard exposes the blade from the side at certain blade heights. Overall, though, it's the manufacturing issues that are the deal breaker.
