worth the wait, it's a silky smooth operator with user-friendly controls and plenty of power. Not only does the new Unisaw live up to its heritage, it also includes a number of notable changes that will pay dividends every time you use it.

A sound platform

The Unisaw's reputation is based on performance and durability.The new Unisaw honors that tradition with American-made materials and a five-

year warranty. According to Delta, 95% of the Unisaw's components—virtually everything but the screws—are currently manufactured and machined in the USA.

Power is supplied by a 3 hp or 5 hp Marathon motor. The motor is mounted on a newly designed one-piece cast iron trunnion.The saw's cabinet is made of heavy-gauge steel and it sits on a cast iron base—this saw weighs nearly 500 lbs.The new Unisaw is equipped with a Biesmeyerfence,a 10" Delta premium saw blade, and an extension table that includes a handy storage drawer.

and just about every woodworker knows what you're talking about. Delta's iconic tablesaw has built a unique legacy by providing reliable performance in countless woodworking shops for over seventy years.

So it's not surprising that Delta's approach to making improvements has been thorough—redesigning the Unisaw took six years. Having lived with the new Unisaw in our shop for some time now, we can say it was definitely

The new Unisaw's table is significantly longer in front of the blade, a boon to both ripping and crosscutting operations.

The riving knife reduces the likelihood of a kickback. It sits below the blade, so you don't have to remove it for non-through cuts, and it travels with the blade during adjustments, so it's always perfectly positioned.

Installing the blade guard assembly takes only seconds. First, pull the release lever to raise the riving knife (l).Then snap in the antikickback pawls [2}. Hook the guard assembly on the riving knife (3) and lock it in place (4).

continued end support, compared to about 12" on a typical 10" tablesaw. In addition to expanding crosscut capacity, the extra length provides more room for setting up a crosscut, and more support for ripping long boards.

A riving knife

To comply with the revised voluntary industry standard (UL 987), the Unisaw is equipped with a riving knife. Like the splitter that it replaces, a riving knife keeps boards from pinching the blade and kicking back during a cut. The Unisaw's riving knife offers two major advantages over a splitter. First, it raises and lowers with the blade, so it's always perfectly positioned. Second, it can be positioned slightly lower than the blade, so it doesn't have to be removed whenever you * want to cut a groove or other type of non-through cut.

The only time you'll have to remove the riving knife—a simple task on this saw—is to install a dado set or other smaller-diameter blades. A riving knife for thin kerf blades is also available from Delta.

User-friendly blade guard

The redesigned blade guard mechanism also meets all the requirements of the revised standard.lt attaches to the riving knife and takes ten seconds or less to remove and reinstall—a great safety feature that leaves few excuses for leaving the blade exposed for any through cut. Ditto for the antikickback pawls.The guard's open-front design allows you to see the blade to set up the cut, but it also allows some chips and dust to get tossed back toward the operator. For increased visibility during set-up, each guard wing locks easily in an upright position.

While making a cut, both guard wings remain flat on the workpiece, whether the blade is positioned at 90° or tilted to any angle. For additional protection, the wings are designed to drop down to the table as soon as possible after the board passes.This maximizes protection at the front of the blade, where it's most warranted, but it leaves the back of the blade partially exposed. So, as with all tablesaws and all blade guard systems, you must always use common sense and follow safe operating procedures.

Easy blade changes

The new Unisaw's generous 5" wide throat opening, an easily accessible arbor lock,and a massive arbor wrench make blade changes easy. Most notably, the arbor nut and flange washer are a single assembly, a terrific little innovation that virtually eliminates the aggravation of dropping the arbor nut into the bottom of the cabinet. This assembly has been available from Delta as an upgrade for a while; it's great to see it on the new Unisaw.

We've been getting very good results with the new Unisaw's factory installed premium blade.This blade features a 50-tooth ATB-R design with sub-micrograin carbide teeth that are generously sized for multiple resharpenings.

Up-front controls

The front-mounted blade-tilt hand wheel is probably the new Unisaw's most obvious change, and it makes blade-tilt adjustments much easier.

The new Unisaw's table is significantly longer in front of the blade, a boon to both ripping and crosscutting operations.

The blade guard's open-front design provides a clear view of the blade, so you can align cuts precisely.

Delta Unisaw Crosscut Guide

The blade guard's open-front design provides a clear view of the blade, so you can align cuts precisely.

An extra-wide throat opening, an arbor lock and a one-piece arbor nut/flange washer assembly combine with a large easy-to-grip arbor wrench to facifitate blade changes.

The miter gauge has nine detents and a spring-loaded override lever that allows the gauge head to swivel freely. Release the override, and it holds the head in any position, so it doesn't move when you tighten the handle.

Both blade adjustment hand wheels are up front, along with a redesigned bevel scale and both bevel stop adjustments.

Both hand wheels operate smoothly. They're geared for fine adjustments and they feature soft-grip handles and large lock wheels.

The speedometer-like bevel scale is large enough to allow making adjustments in increments as small as 1/4°, and it's enclosed, so the pointer can't get bent out of adjustment. The adjustment bolts for the 90° and 45° stops are conveniently located on the front of the cabinet, to the left and right of the bevel gauge.

The large off button on the magnetic controls works from nearly any angle, which is great for those times when your knee or thigh becomes an extra hand.The controls can be locked out permanently, by padlocking, or temporarily (for blade changes and such), by inserting an Allen wrench.

Miter gauge

The miter gauge bar is equipped with adjustment screws, so you can dial in a perfect fit in the saw's miter slots.The gauge itself features nine detents (at 90', 30s, 45°, 60" and 75°), a spring-loaded detent override lever and a soft-grip handle.

To adjust the gauge, you loosen the handle, depress the override lever and go. Releasing the override lever locks the gauge in any position on the bar, so it won't move when you tighten the handle.The detents can be adjusted by moving the metal plates on the bottom of the gauge {each plate has three detents). When you need to fudge the numbers, the override lever is successful down to increments of about 1 .To make more precise adjustments, you'll have to loosen the plates.

Fence

All new Untsaws are equipped with Biesemeyer fences.The 3 bp saw is available with either a 36" fence or a 52" fence; the 5 hp saw comes with a 52" fence.The fence tube is made of 14-gauge extruded aluminum and is really tough,according to Delta, despite being surprisingly light in weight.The fence scale is easy to read and adjust, with see-through pointers and hairline indicators on both sides. The cam lock soft-grip handle snaps positively into place, and once it's there, It doesn't move. When you reposition the fence, a magnet holds the handle up and out of the way.The fence faces are replaceable,although you have to remove the laminate overlays to access the mounting screws.

Dust collection

The new Unisaw is equipped with a 5" diameter main dust port, which allows better dust collection than most other 10" saws, because it allows connecting the saw to 5"dia. pipe. (A 5" to 4" reducer is included with the saw to interface with 4" systems already in place.) The saw's blade shroud routs directly to the main dust port, which also includes openings to collect dust from the saw cabinet,The cabinet itself is completely enclosed and the motor cover and front entry doors are gasketed.

One Serious Bandsaw a few years back, I found this bandsaw in someone's barn, in very poor shape. It was laying on its side in the mud, with the table broken in half. But what a beauty!

! moved it to my shop with a backhoe, welded the table back together, restored all the hardware, and repainted everything. I also added doors in front of the wheels-as it was originally built, it didn't have any doors at all.

This bandsaw was made by London, Berry & Orton (the Atlantic Tool Works) of Philadelphia in 1897.lt was sold by Chas. A Strelinger &Co.,of Detroit, whose nameplate covers the original manufacturer's.

The huge wheels on this saw measure 36" dia.,and the blade is 17-1/2' long. Originally, the saw was powered by a belt from a line shaft; the 3hp electric motor was added later. And if you are wondering, yes, it runs fine! In fact, it's quieter than my 14" bandsaw.

YEARS AGO, I MADE A CORNER CUPBOARD

from black walnut. I thought the wood was magnificent, but a can of rusty cut nails I used in building it proved to be far more interesting, taking me on an unexpected journey into my past

My father gave me these nails, saying that they were left over from the demolition of my grandpap * Zeda's too! shed. As a boy, I loved opening the shed's door, seeing Zeda's old and weathered gardening tools,and smelling the peculiar aroma of mother earth subtly sea soned with old fertilizer and stagnant air.Through all kinds of weather, Zeda would spend hours gardening, tinkering, or idling away the time with visitors. He loved it when his grandchildren came by for a visit. Sometimes he'd break from his daily routine and dazzle us with a riddle or trick until we thought he was larger than life.

When I built the cupboard, I spent over an hour straightening those nails. After driving the final nail into the cupboard's back boards, I paused for a nostalgic moment. Suddenly, I felt the lives, histories and souls of three generations of my family converge.

The cupboard still stands proudly in my dining room. Its real meaning lies not in its external beauty, but in the living history provided by a handful of hidden cut nails.This cupboard's genuine character, as is often the case with people we know and love, lies comfortably and deep within.
