The Case tor a Dedicated Base
One of the downsides of most universal bases is the time you have to spend assembling them (more on this later). Of course you only have to do this once (unless you want to change it for another tool). Still, you don't want assembly to be a hassle. And thafs where the Jet universal base shines (photo at right).
Note: This base is rated for 600 lbs. Jet makes another mobile base for tools up to 1200 lbs.
Assembling the base takes a couple minutes at most. All you have to do is slip the steel bars into the corners, position them to match the mobile base to the base of your tool, and then "lock" everything in place with spring-loaded pins (see inset).
This ease of assembly does come at a sacrifice. Because the rails are held in each corner by a single pin and not bolted, the base isn't as rigid as I'd prefer. It has a little "flex" to it. YouH probably notice this most as
Instead of a "one-size-fits-all" approach, you might want to consider a dedicated base, like the one shown at right.
Now you might be thinking that once a mobile base is under a tool, isn't it pretty much "dedicated?" What makes a dedicated base different is that ifs designed to fit a specific tool (or power

Some tool manufacturers make dedicated bases for their tools. But HTC Products Inc. has "dedicated" themselves to this type of base. They make a base for just about any tool. (They'll even custom make one for you.)

Cost - About the only downside to a dedicated base is the cost Ifs probably going to run at least twice as much (or more) than a typical universal base. For sources of dedicated bases, see page 35.

Speaking of locking the base in place, thafs one feature of the Jet base I really liked. I don't have to

A simple press of each foot lever locks (or unlocks) the wheels of the base.
