5.0 out of 5 stars Durable, despite plastic casters one reviewer didn't like, April 15, 2006

This review is from: Jet 708119 JMB-UMB-HD Universal Mobile Base (Tools & Home Improvement)

I own and have used Delta, HTC, Ridgid, Grizzly, and home built mobile stands with $50 casters on each corner, spending up to $300 for an HTC custom built for my MiniMax (with plastic casters by the way). While cast iron or rubber-tired steel casters have their place, plastic has held up just fine for my use (which includes 1/2 the shop with concrete and 1/2 in rough plywood flooring. I frequently negotiate a 1/4" bump between the wood and concrete and also go over a sill to the outside. The Jets have done just fine.

What I like about the Jet, compared to the HTC and others, is that it's easy to back tools against a wall and lock them in place with the Jet. One tip -- you do want to secure your tool to the base for maximum stability. A plywood sub-base attached to both the often flimsy open sheet metal base of your tool and then with one bolt through each corner brace of the Jet base removes a lot of flex. Flex is the one limitation of the Jet (it really should get 4.5 stars because of this), but is easily overcome to create a 5 star solution.

1.0 out of 5 stars always mobile, June 23, 2003

By A Customer

This review is from: Jet 708119 JMB-UMB-HD Universal Mobile Base (Tools & Home Improvement)

This base would not immobilize my Super Saw for use. With all four casters locked, it still moved when I leaned on it. Also, it requires locking/unlocking each wheel independently (a pain) and it seemed no matter which way I moved the saw, one of the swivel casters was under the steel plate, requiring me to bend down and engage the butterfly lock with my hands. There is no privision for leveling/stabilizing the tool. In contrast, the Delta contractor's saw base I replaced it with has one big lever you step on, after which you can literally spin the saw around and nice big adjustable rubber feet to stabilize it. Definitely worth another $.

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.
