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.

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.

I ordered this base after looking at a number of products. It is a great product. It is sturdy and the assembly uses no tools: it just snaps together. It rolls easily even with 500 lb of machine on it.

The minimum size is listed as 24" X 24" but this is not true. The minimum size is 18". You can make an 18" side by cutting one of the bars is half with a hacksaw. This takes less than ten minutes. Now the two 12" short bars are used to join the short sides. I used this technique to make a base for a band saw with a footprint of about 18" by 30" and it worked very well.

Having a small shop, I get to be creative in using my available space. Over the years I've used many mobile bases for my various equipment some good, others literally dangerous to operate. I use a 500 lb bandsaw. Moving it had been a challenge because it's top heavy, and I had originally mounted it on a flimsy, three-wheeled mobile base. Too many times I came close to tipping it over. For years I knew how to make it safer, but never made the change to a better base... until I got fed up with the dangerous situation. I decided on this heavy duty base, and am glad I did. The assembly instructions were clear and intuitive. I modified my installation to widen the footprint and further reduce the tipping potential. I mounted a 3/4 inch solid-core plywood panel to the base of the saw. I cut it about 6 inches wider (all four sides) than the saw's base, bolted it to the saw base, then bolted the ply to the mobile base. I opted for the heavy duty model, even though the less expensive model would have worked. For me, it's the perfect solution. Soon I'll be replacing my other lesser quality mobile bases with two just like this one.

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.
