PortaMate Heavy Duty Universal Mobile Base Bora PM-2500. A Tough, Fully Adjustable Mobile Base for Mobilizing Large Tools, Machines and Other Applications

Reviewed other products from Amazon - other reviewers noted many have plastic foot cams to raise and lower base. This one has steel parts; except for the wheels, the entire device is steel - very sturdy and not at all fragile. My Craftsman table saw - under 100 lbs, poses no challenge whatsoever to this base.The assembly directions were not ideal, but they got the job done. Parts orientation is easier to determine from the exploded drawing at the beginning of the manual. Actual assembly is straightforward; the real fun begins when you mount your table saw or other tool. Finding the right dimensions is a "jigsaw puzzle", not covered in the instruction manual, and a bit of a challenge until you figure it out. You can move the bars in 1" increments, and the larger bar on each side (as I assembled it) has slots that allow about ½" movement, so accuracy is attainable. I wound up assembling and disassembling the side bars multiple times finding the right dimension for locating the feet of the saw table over the holes in the mobile base corner pieces. It helps to use a floor jack or something to get the saw just above the base an inch or so, making the process a bit less "work". By adjusting the "slotted" bar at the corner, then where it attaches to the smaller bar with holes, it seems you can get infinite adjustment, but you have to fiddle a lot to actually get the saw fastened to the base. Once done, I tightened everything up and was good to go.A couple of things to remember - the saw on its base is now about 4 to 5" deeper because of the location on the corner pieces and the foot-cams. My saw doesn't fit as nicely on the side of the garage as it used to; just a "heads up" if you have limited space.One of the foot cams has more action in raising the base than the other. I studied the base a long time to figure that out, and am convinced I cannot adjust that out; it appears to be a slight misalignment of the welded bracket on the corner piece - even ⅛" would be enough to change the camping action. It is not a deal breaker, but a bit annoying they couldn't locate the foot-cam bracket more accurately.All in all, this thing will last longer than the saw - it is very sturdy, heavy-gauge metal, with only the wheels being plastic. A good buy for just a few dollars more than the plastic el-cheapo model.

I have now purchased two of these, one for a table saw one for a band saw. Assembling the first one was really tedious since I had a splint on one hand and opposable thumbs are important (but even with that handicap I did get it assembled). Once it was together, it worked fine and being able to move my table saw around really made my workspace more manageable.So I, purchased a second one. It went together in a fraction of the time (with two hands working) and has proved just as valuable.There are a lot of negative reviews for this product and I just don't get it! Both of mine function flawlessly. The finish quality is good; they roll well and steer well and they are stable when locked down (because they lock by raising the wheels and setting the base down on adjustable rubber feet rather than clamping the caster wheels). My use is not industrial--I don't move these around constantly and I'm not pushing the weight limit but for my home shop they are great. I wish I had done this years ago.Nobody paid me or gave me anything free for this review.

I understand Bora used to have a reputation for quality. But after being acquired by Ox Tools, the manufacturing errors have made this product unusable. Two of the four corner supports were shipped without the threads necessary for installing the casters. They shipped new ones within a week or so. No big deal. When I completed the assembly process (not easy, since no instructions were provided) and set it on the floor, I found that the foot levers used to lower and raise the casters would not stay in place. It was now the end of July. I was informed that the levers were not manufactured properly and that they would ship new ones. However, they would not be in stock until August 22nd. In early September, with no replacements in hand, I again got in touch with Ox. With the additional delay, I asked that they ship a new unit (Amazon offers next day delivery). "Ox Customer Service" not only refused they advised me that new parts would not be available until November! I should have read current Amazon reviews instead of just looking at the history. Many, if not most, are 1 or 2 stars. So, take caution. If you're masochistic and decide to order from Bora (Ox), plan on returning to Amazon within the 30 day return window. Amazon remains an excellent business to do business with, but I question how long they'll be willing to supply Ox garbage.
