    Best Mobile Base yet
  

*by A***K on Reviewed in the United States on January 26, 2006*

I recently purchased a new JET 708781K JWSS-CS-PF Supersaw with 30" XACTA fence and slider that tips the scales at 420 pounds.  I wanted to buy a heavier duty base than my existing HTC or Delta bases (HTC 1000 and Delta 50-345).Although the HTC and Delta bases are good, there really is no way to compare it to the Jet universal base.  The other two bases support 300-400 pounds and the Jet supports 1200 pounds.The Delta and HTC took a significant amount of time to assemble; the Delta about 2 hours since you had to make your own wood stock and the HTC about an hour since there were many bolts to install.The Delta and HTC both lift up the machine off the ground with foot levers.  This works ok if the tool is not too heavy.  The Jet base casters just lock or un-lock, NO tipping of the machine in anyway, which gives me piece of mind with a 420 saw.Since it is designed to stay off the floor permenently, the base actually lifts the machine 3/4's of an inch off the floor as opposed to the HTC which is a little less than a ½ an inch.  This was not a big deal for me, but it is different.  Since the casters have to support the machine all the time, they are super heavy duty.The best part of this base is its ease of assembly - NO TOOLS REQUIRED!It took me longer to unpack it from the box (about 10 minutes) than to actually assemble (5 minutes).  The corners are very heavy duty with welded construction (I uploaded pictures for everyone).  To assemble, you take the cross bars and simply slide them in the slots.  There are spring loaded pins that keep them in position.  You can change the size of the base in under a minute, but pulling the pin and sliding the bars larger or smaller, that's incredible!With the HTC, you can adjust the size by disassembling the many nuts and bolts.  With the Delta, forget it since you had to cut the wood to specific dimensions. The Jet base can be reconfigured to fit any tool in minutes.Do yourself a favor, spend the extra money to get this base that will last you a lifetime, will allow you to use it in 5 minutes and get you back in the workshop and make some more sawdust!

    Casters are plastic and don't lock!
  

*by T***S on Reviewed in the United States on April 13, 2006*

OK, after waiting a few weeks on backorder, I just received my Jet 708119 Industrial-Duty Universal Mobile Base from my favorite online store, Amazon."Industrial"? With all due respect to Jet and some the other reviewers here, you've got to be kidding me! (I deducted one star for every $10 by which this unit is overpriced, but ran out of stars.)Word: By spending a few hundred bucks on a small metal press, drill press, MIG welder, some raw steel, and a couple gross of the kind of cheap, "lockable" (not!) plastic casters included with this unit, you could rapidly manufacture these things in your garage for $15 a pop, max.Yeah, I know, I know. Why, this unit reliably holds 1200 lbs! [Highly doubtful. But even if the cheap plastic of which these casters are made can handle that kind of load, normal motion over a concrete floor will wear them down to nubbins in no time flat.] This unit is stable! [No way - I can turn every one of the "locked" casters with my thumb, indicating that they will do almost nothing to resist any lateral force of an order sufficient to overcome the inertia of any tool weighing much over 100 lbs.] This unit is a whole lot better than other comparable units! [If so, then other mobile bases are even more of a joke than this one.]Good grief, Jet. If you're going to manufacture an "industrial" mobile base and then charge the end user up to ten times the cost for which he could make the thing himself (with the abovementioned tools), at least use steel casters!Yeah, yeah, I know - what about those poor souls with wooden instead of concrete floors? [Clue: People with wooden floors shouldn't be rolling 1200 lb. tools around on them. And in any case, why not let everybody know the casters are plastic, so that those who have real concrete shop floors can try something else?] But steel casters don't lock as well as plastic or rubber! [Clue: Maybe not using friction alone, like these cheap/nonfunctional casters vainly attempt to do. But steel casters could easily be manufactured or modified  with a locking gear, a spring-loaded pin through a hole in the wheel, or some other positive locking mechanism, no problem.]If one didn't have to worry about matching the ridiculous corporate advertising budgets dedicated to hyping this kind of function-challenged product, one could double his money selling superior units for about $25 or $30 each. Argue all you like, but that's a fact.I don't know about anyone else, but resist as I might, I get offended when my intelligence is insulted by people trying to pass off mere plastic, space-age or otherwise, as a heavy duty, abrasion-resistant load-bearing material suitable for this kind of application, especially in unmotorized, easy-to-manufacture Taiwanese products that have almost no moving parts and a price tag approaching $100...particularly when the casters don't even lock as advertised.Caveat emptor. The fit and finish are nice enough, but in this kind of product, functionality is all that counts.

    Well made and suits my application perfectly, but a little expensive
  

*by A***R on Reviewed in the United States on December 11, 2019*

Bought this, along with the  Jet-Mobile Base Extension Kit (708158) for the Jet 725003K ProShop II 230V 52" Rip with Cast Wings after reading every review I could find. The products are well made and work well on a very smooth garage floor. (Some reviews of the base with extension indicated they required additional reinforcement, but this could be due to stress applied by rougher concrete, or other, floors. Alternatively, since my application allowed me to keep all of the support members at their shortest and, hence, strongest lengths, it may not represent stress situations other customers ran into.) The hard plastic (or rubber?) casters should not be a problem on a smooth floor but might take abuse on rough floors. While I am satisfied with the product quality, I would have preferred to get it at a slightly lower price point.It took some thought to figure out how to gently set a reasonably heavy (326 lbs), already assembled, table in the base without any help, so I suggest anyone purchasing this get help or plan ahead when it comes time to put your heavy duty workshop tool in it.
