Old saws that ran on jackshafts initialy didnt tilt then some one got the idea to cut bevels and they tilted the table. as few as 30 years ago I knew of a company that still had some of these in play with a dedicated motor. they also had some industrial deltas. For set ups on the work sheets they would refer to "tilt table" or "tilt arbor" saw.
Thank you Bruce but boring, I am already, you know me or ask my wife.
No need for more boredom.
All saws today are "tilting arbor" (of course someone will prover me wrong)
The one in the ad is very well priced. It is some kind of Unisaw. It looks looks like it is in pretty good condition
I am almost tempted but I really do not want or need on more table saw.
I have a couple of old Sears saws on the shelf that have tilt tables, a 'Dunlap' and 'Companion.' To lower the blade you also raise the table. Cheaper way to make a little saw.
C Plus, tilting arbor saws tilt the blade and arbor not the table. as Bert says almost all if not all table saws today are tilting arbor saws. The are much safer than a tilting table saw.
These DR 12"-14" saws are very common in my area, used in multiple military and other Gov sites. And usually sell at very reasonable prices.
They weigh around 950lbs, but actually easy to move by pulling the table and motor. The motors are usually 5 or 7.5 hp 3 phase.
The Autogen phase converters that Grizzly sells will run them nicely with no problems.
The table with wings is 48" across, with a 38" depth giving around 8" more room to the blade up front then a 10" saw.
A nice feature is the threaded part of the arbor is removable, making any blade hole size from 5/8" to 1 1/4" usable, spare arbors can be purchased from Grizzly, as it was used on their G5959 saws.
The saw will take a 14" blade, but it will not fully retract it, leaving 1" protruding when the elevation wheel is moved to the lowest position. A 14" blade will produce a 5" depth of cut.
The very last of these saws used a micro groove belt, most will have 4 v belts. When adjusted correctly the saw will run smooth enough to stand a dime on the table.
Nice arbor bearing design using a double row bearing at the blade end secured with a nut, and a single row bearing at the other end also secured with a nut. This arrangement allows for better heat expansion, and follows better machine tool design.
There is ample room in the cabinet for ease of any maintenance that is seldom needed.
Not intended for the hobbyist, an industrial grade machine with due caution can be used as such however.
Here's a pic of a tilting table saw…the arbor does not tilt.
Tilt-top saws were common on the pages of 1930's-1940's Popular Mechanics magazines. This might explain why Rockwell was compelled to identify the high-end saw in the original post as a "Tilting Arbor' saw, since both were eminent on the market at one time. (from Google Images)
One place my Daughter had rented one year, in the Garage, there was a tilting table saw, with a 10" blade, no less. The saw was bolted to a 2x pine board. Top may have been 18" x 18" square. A v belt ran back to a 110v motor, also bolted to the board. Never did find the miter gauge, "Fence" was there, allright, but I doubt if it could have been usable. Name plate did say "Sears" on it , though…..
Left that thing, motor and all when she moved back out… except for the saw blades. needed some "beaters" for the barn wood i worked on….
The used to make large tilting tables on saws. Then they discovered they were very dangerous , as heavy pieces of wood were being gravitationally forced left or right against the blade as the cut was being made ,causing binding etc. On top of this it became a very difficult job holding the wood steady as it tried again due to gravity to slide off the table onto the floor.MY advice would be to leave them well alone .Sorry if that's not what you wanted to hear, but it is why they don't make them here in the Uk Or Europe anymore.Alistair
Tilt table saws were used in industrial applications. The arbor
is incredibly stable since it is fixed. They do make accurate
cuts and in beveling the fence is placed downhill so gravity
helps with an accurate cut. These saws predated the widespread
use of sheet goods that occurred after WW2. Before then,
even industrial table saws seldom had large rip capacities
because solid boards seldom come in widths wider than
24" or so.
I haven't really considered it before, but I do think it may
be possible to get more cutting height with a tilt-table
saw. If you look at a Northfield tilt-arbor saw, it gets
its stunning performance from a direct drive, which requires
a large blade to get a 4" deep cut because the motor
gets in the way.
What about the Shop Smith? Tilting table. I learned to call the "table saw" a circular saw because it used a circular blade. My shop teacher pointed out that all stationary saws had a table.
Circular saw, band saw and jig saw. We had those in our high school shop. That was when portable saws were called sabre saws and not jig saws. The Delta jig saw we had used a wide blade that was larger or at least as large as a coping saw blade. Scroll saws were not in use in pour area. I have a BS in Industrial Arts and we didn't have a scroll saw in our college shop either.
