Delta Unisaw 34-450

Name: Delta Unisaw 34-450
Brand: Delta
Availability: InStock

Ask old-iron woodworkers which cabinet saw the others get measured against, and most will say the Unisaw. Delta brought it out in late 1938, and from the 1950s into the 1980s it sold under the Rockwell name as the 34-450 bare saw, the 34-451 with wings and guard, and a run of package numbers. Delta's own 34-670 is a 1986 motorized saw, not a Unisaw. After 1952 Unisaws were built in Tupelo, Mississippi, with the motor inside the cabinet turning the arbor on three V-belts. Small details date one. The Jet-Lock fence arrived in 1960 and T-slots in the miter slots in 1961, and the motor cover stayed cast iron until 1967 and the base until 1977. Find a single-phase Unisaw with its fence, guard and wings and you may never shop for a table saw again.

Power, iron, fence and freight

Power and phase: In 1961 Delta offered the Unisaw bare or as packages with a 1-1/2 HP single-phase motor at 115/230 V or a 2 HP three-phase motor. The motor plate in the photos tells you which one this is. A three-phase Unisaw needs a VFD or a rotary converter on house power, or a single-phase motor swap.
Motor and bearings: The motor sits inside the cabinet and drives the arbor with three matched V-belts. Ask for a video of the saw starting from rest. It should spin up quickly, and a thump or slap from the cabinet usually means worn belts.
Runout: The 5/8 in arbor runs on 17 x 40 mm ball bearings, with an extended-inner-ring version on older saws, and both are standard bearings. Check the arbor with a dial indicator if you can. Otherwise ask whether the bearings have been replaced and listen for rumble in the video.
Table and rust: The table and wings are cast iron, and from 1961 the miter slots have T-slots. Ask for a photo of the top in raking light. Light rust comes off with synthetic steel wool or 400-grit paper and mineral spirits, but cracks around the slots or a wing that won't sit flush are real faults.
Fence, guards and gauges: The bare 1961 saw came with a Jet-Lock rip fence (introduced in 1960), a miter gauge, guide bars and a table insert, but no guard, splitter or wings. The 34-451 added the wings and the Super-Safe guard. So check exactly what's in the photos, because a lot of Unisaws have lost the guard and splitter.
Trunnions and adjustments: The blade raises and tilts on the trunnions under the table. Ask the seller to crank the blade from full height to the bottom and tilt it to 45 degrees. Both wheels should turn smoothly, and sawdust packed into the trunnions is the usual reason they don't.
Blades and knives: It takes standard 10 in blades on a 5/8 in arbor, so blades and dado sets are easy. Inserts, guards and fence parts are the bits to look for.
Dating it: Unisaws made before 1953 carry a Milwaukee address and later ones Pittsburgh. Serials on Tupelo-built saws start with two letters (CY is 1963, DS to EF 1968, GZ to HR 1975), and from 1982 they're date codes. VintageMachinery.org has the full table. Running changes help too, like the cast-iron motor cover used until 1967 and the cast-iron base until 1977.
Moving it: Delta listed the bare saw at 279 lb and a complete single-phase package at 422 lb in 1961. Take the wings, fence and motor out to lighten it. With those off, two or three people can load it, or book freight.
Safety upgrades: Many have lost their guard and splitter, so find or buy one before the first rip. Replace an old cloth or cracked cord and check that the switch turns the saw off cleanly.

Should come with it

Rip fence and guide bars (Jet-Lock from 1960)
Miter gauge and table insert
Extension wings
Blade guard and splitter (34-471 Super-Safe on the 34-451)
Motor and switch or starter

Hard to find if missing

Cast-iron motor cover (pre-1967)
Super-Safe guard and splitter
Original Jet-Lock fence parts

Check the listing photos against these lists, and ask the seller about anything you can’t see. A missing fence, guard or motor should come off the price.

What to check

Worn belts, packed sawdust in the trunnions and tired arbor bearings are the usual jobs, and all are fixable. Missing guards and fences and three-phase motors matter more to the price.

01Motor plate: Ask for a photo of the motor plate. Single-phase at 115/230 V runs at home, and three-phase needs a VFD.
02Serial plate: Ask for a photo of the serial plate. The prefix or date code tells you the year.
03Height and tilt: Ask the seller to raise, lower and tilt the blade on video. Both wheels should turn smoothly end to end.
04Running: Ask for a video of it starting and running. It should spin up fast without a belt slap.
05Table and wings: Look at the top and wings in a raking-light photo. Light rust is fine, but cracks aren't.
06Fence: Check the photos for the fence and both guide bars. It should lock square and slide freely.
07Guard and splitter: Check whether the guard and splitter come with it. If not, budget for one before you rip.
08Moving it: Plan the move before you pay. With the motor and wings in, it's well over 400 lb.

Buying guide

Which one to buy

§ Oct 19, 2026

With any Unisaw, ask about phase first, since three-phase needs a VFD, a rotary converter or a new motor, and the dealer saws here are three-phase. That makes the $1,100 Rockwell-Delta titled single phase our pick. The $799 3 HP saw with a Biesemeyer is cheaper if its plate reads single-phase. Plenty are for sale, mostly pickup asks of $850-1,300. Check for fence, wings and guard, and plan the move, since a 1961 single-phase package shipped at 422 lb.
