JET HD Universal Mobile Base, 24" x 24" to 34" x 34", 1200 Lb. Capacity (JMB-UMB-HD)

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!

I bought this to use as a mobile base for my Rikon 18" band saw. Since 24x24 is the min size it will go to I had decided to cut two of the flat rods but once I received I decided not to go this way. I made a sandwich of two 24" x 30" 3/4" thick plywood sheets and mounted the saw on top with 4 screws to keep it secure. Due to the wider base the Band Saw is even more stable and the whole base feel solid and strong. The facility in putting this together without any tools make assembly a snap. A bit pricey but NOT when you see the quality construction of the base. My only gripe is that id does not have a better way to anchor the saw when positioned. The wheels do lock but the say still moves if pushed a bit hard. IN this department the Shop Fox bases are better than the Jet. Overall a great products and i will buy again if I need to in the future.

In my small shop, space is a premium and moving a heavy table saw and stand is a nuisance. The Jet 708119 JMB-UMB-HD Universal Mobile Base is a great solution. It took five minutes to assemble and set the saw/stand onto the base. Easily moves around and the sturdy castors have suitable locks that serve my purposes perfectly. Other reviewers go into significant details on how to make it really solid on hard floors, but I didn't have that issue. The steel and welds are well done and very sturdy; 1/4" steel, for the most part. The shipping box arrived via UPS in undamaged condition and the unit is well packed in expanded styrene foam packaging for protection. I'm very pleased.

I see the price has risen....mine was $79.99 with the free shipping. But this unit is very good. It took all of 3 minutes to put it together and about 10 more to slide it under my Delta 10" Radial Arm Saw. It came with all four corners/casters fully assembled, all I had to do was measure, pull out the spring loaded stops and slide the corners to the desired length on the stretchers. Truly, it could not be easier or quicker! When all four of the casters are locked it does not move unless you put so much pressure against it that they slide on the concrete (which incidentally I did). However, I found that it seemed to need more pressure to slide the saw now with the Jet Base than it did when all I had was the saw sitting on the shop floor. Best of all, finally, I can put the saw out of the middle of the floor....EASILY!! Highly recommended.

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.

This takes 2 minutes to assemble. No bag of bolts or screws, and you can put the instructions away! The package has eight pieces: 4 bars, 4 corners, pre-assembled with wheels. The bars simply insert into each side of the corners and you use a spring loaded push pin to lock into place. It couldn't be any easier. This unit is very heavy duty, capable of holding 1200 pounds. Minimum size is 24x24, max size is 34x34. There is about a half inch of clearance, and all 4 wheels are lockable. Two of the wheels have nice levers making it easy to lock and unlock with your foot. The other two wheels can lock with your foot as well, but the locks are on the axle of the wheel (locking caster wheels). I am using this for a 600 pound, 20 inch Jet planer.

This mobile base is sturdy and easy to assemble. If only jet would have made it adjustable to the size of their cabinet saw (Xacta). I had to modify the base by cutting the rails shorter and drilling new holes for the pins to lock into. I made the internal diminsions one quarter of an inch bigger than the footprint of the saw. I then cut two pieces of three quarter inch plywood to the internal demintions and glued and screwed them together. Then I placed this piece inside the base and drilled a whole through each corner of the plywood and metal base. I bolted it all together with four bolts. After placing my saw on my modified base, I have found it to be very sturdy and easy to roll around.

this says that it will support up to 1200 pounds. My 800-pound Band Saw does not roll very smooth. The swivel casters seem to bind up and not swivel very easy. Not sure if this will last.
