Do you Wish You Could...
...Roll Your Shopsmith Effortlessly From Location To Location With One Finger ?
Our New 3" Diameter Caster Wheels Will Make That Wish Come True !
Prepare To Be Amazed !
These big 3" diameter by 1-1/4" wide casters feature tough, polyolefin wheels and rugged 3/8" steel axles that roll super-smoothly on sealed ball bearings.
Smooth Ride
Their soft, non-marring polyurethane tires deliver the perfect combination of shock absorption for a smooth, quiet "ride"...and resistance to developing flat spots. The tires are both chemically and mechanically bonded to the wheels so they won't come off --- plus, they're certified to be resistant to the oils and chemicals found in the home shop.
Rugged Performance
Rated at 200# per Caster, they rotate on beefy 7/16" diameter grip-ring stems and double ball bearing 360° swivels with hardened raceways and metal covers that shield the bearings from dust and debris. They swivel instantly, changing direction with practically zero resistance!
Easy Installation
Installing them on your existing Shopsmith Retractable Caster Brackets is a "breeze". Just re-drill some new bracket mounting holes in the legs of your Shopsmith (we provide a paper guide template for positioning)... pull the old casters out... pop the new casters in... bolt the brackets into the new position...and you're done in about half an hour ! That's all there is to it.
The Proof Is In These Test Results
We tested these casters against our original Mark V Casters and discovered some remarkable results. Here's what we did:
We set-up a new Mark 7 as a table saw / jointer combination, weighing in at a hefty 284 lbs... then ran a series of tests with the "old" 2" and "new" 3" casters on a smooth, swept tiled floor.
We used a 40# capacity spring scale for our tests...attached to the table carriage at the center of mass on the operator side of the machine... then pulled the machine sideways to take our measurements.
First, we set each set of casters so the wheels were 90-degrees to our pull direction. Then, we rotated the wheels so they were set parallel with our pull direction.
The results (showing the amount of pull force required) are shown below.
