Delta Band Saw 28 203: What to Check Before Buying or Restoring One

You found a Delta 28-203 band saw on Craigslist for 200 dollars. The seller says it runs but needs tires. You have been looking for a 14-inch band saw and this one seems like a good deal. Before you drive an hour to look at it, you want to know what to check so you do not buy a machine that is beyond saving.

The Delta 28-203 is one of the most common 14-inch band saws on the used market. It was produced for decades and thousands are still in use. It is a solid, well-built saw that is worth restoring if the frame and wheels are in good condition. Here is what to check before buying and how to plan a restoration.

What to Inspect Before Buying

Frame and Column

The cast iron frame is the backbone of the saw. Check for cracks, especially around the column where the upper wheel housing meets the lower frame. A cracked frame is not worth fixing. Look for welds or repairs that indicate the saw was dropped or overloaded.

Check the column for twist. Place a straightedge across the table mounting surface and the upper wheel mounting surface. They should be parallel. If the column is twisted, the saw was stressed and the alignment may be off.

Wheels

Turn both wheels by hand. They should spin freely with no grinding or rumbling. If you hear bearing noise, the wheel bearings need replacement. This is a common issue on older saws and is not a deal-breaker, but factor the cost (20 to 40 dollars per bearing) into your offer.

Check the wheels for cracks and chips. A cracked wheel is dangerous and must be replaced. Delta wheels are available but can be expensive (100 to 200 dollars each).

Check the tire condition. If the tires are cracked, hardened, or have flat spots, they need replacement. This is expected on any saw over 10 years old. Urethane replacement tires cost 30 to 50 dollars for the pair.

Table

The table on the 28-203 is cast iron. Check for warping, deep scratches, and rust. Light surface rust is fine and will clean up. Deep pitting or warping is a problem. The table should be flat when checked with a straightedge.

Check the table tilt mechanism. The table should tilt smoothly from 0 to 45 degrees and lock securely. If the trunnion is broken or the lock is stripped, the table will not hold position.

Motor

Plug in the saw and turn it on. The motor should start smoothly and run quietly. Listen for grinding (bad bearings), humming without starting (bad capacitor), or intermittent operation (bad switch or wiring).

The 28-203 typically has a 3/4 HP motor. This is adequate for most work. If the motor is bad, replacement motors are available for 100 to 200 dollars.

Blade Guides

Check the blade guide condition. The stock guides are metal blocks. They should move freely and adjust smoothly. If they are frozen with rust or damaged, they need replacement or rebuilding. Cool Blocks or Carter bearing guides are the standard upgrade.

Fence and Miter Gauge

The 28-203 may or may not come with a fence and miter gauge. If included, check that the fence is straight and locks securely. The stock Delta fence is adequate but not precision. If missing, aftermarket fences from Kreg or Carter are better options.

Blade Tensioner

Check the blade tension mechanism. The spring should be strong enough to tension the blade. If the spring is weak or broken, the blade will not tension properly. Replacement springs are available and inexpensive (10 to 15 dollars).

Restoration Steps

If you buy the saw, here is the order of restoration.

1. Replace the tires. This is the first step. Remove the old tires, clean the wheel rims, and install urethane tires. Soak the urethane tires in hot water for 10 minutes before installation. This single step fixes most tracking problems.

2. Replace the wheel bearings. If the bearings are noisy, press them out and install new ones. The bearing numbers are commonly 6204ZZ (lower wheel) and 6203ZZ (upper wheel), but check your old bearings for the exact numbers. Cost is 10 to 20 dollars per bearing.

3. Clean and lubricate. Clean all surfaces with a wire brush and solvent. Apply wax or paste wax to the table to prevent rust and reduce friction. Oil the trunnion pivots and the tensioner threads.

4. Upgrade the blade guides. Replace the stock metal blocks with Cool Blocks (20 dollars) or Carter bearing guides (100 to 150 dollars). This is the most impactful upgrade you can make.

5. Install a new blade. The 28-203 uses a 93-1/2 inch blade. Start with a 3/8 inch, 4 TPI skip tooth bi-metal blade for general woodworking. This handles 80 percent of tasks.

6. Align the table. Check the table for square to the blade. Shim the trunnion if needed. A misaligned table causes angled cuts.

7. Align the fence. If you have a fence, align it parallel to the blade. If you do not have a fence, consider buying a Kreg or Carter fence for accurate ripping and resawing.

The 93-1/2 inch blade is one of the most common blade lengths in the world. You will never have trouble finding blades for this saw.

Is It Worth Restoring?

If you can buy the saw for 200 dollars or less and the frame and wheels are sound, yes. A fully restored 28-203 with new tires, bearings, guides, and a good blade will outperform a new 500 dollar saw. The cast iron frame is heavier and more rigid than most modern saws in the same price range.

If the frame is cracked, the wheels are damaged, or the motor is bad and the total repair cost exceeds 400 dollars, you are better off buying a new saw.
