Bora Portamate Mobile Base PM-3550 Industrial Strength with Swivel Wheels – Universal, Super Heavy Duty, Adjustable Rolling Kit, Dolly Roller for Equipment, Power Tools, Machines- 1500 lb Capacity

UPDATE: I've had my 480 pound jointer/planer on this mobile base for over a year now and have started to notice the flanges where the wheels attach get in the way and do not allow the wheels to fully rotate when under weight. Not sure why because nothing looks like it has bent out of shape. Anyway, I placed four 1/2" washers between each wheel and its mounting plate raising the flanges away from the wheel. Now it works even better than new allowing me to change directions with very little effort when moving it around my shop.I understand Boar has come out with a newer base that has larger wheels that might avoid this issue. You may want to check that one out as well to see if it meets your needs.The Portamate PM-3550 PM-3550 Super Duty Mobile Base-All Swivel Wheels is an excellent mobile base. I received it in excellent condition contrary to some other reviews and found the base easy to assemble, though I recommend having two people available to get a heavy tool into place on the base.I put mine under a 480 pound jointer/planer and since all of the wheels swivel it is very easy to maneuver anywhere in the shop. The four leveling feet make it easy to stabilize the tool on an uneven floor. When the wheels are down just make sure all four pads are lightly touching the floor. Then when you raise the the wheels (which have an easy and light motion) the tool sits firmly in place without moving or tipping to any one corner. Even when under power .I looked at a lot of other mobile bases but this base with its large weight capacity, all swivel wheels and ease of leveling make it a great base for the price.

I bought this for a Davis Wells 20" band saw. If you have never seen one, it's about 600 lbs of cast iron and it's a beast to move without wheels. I ordered this rolling frame because I liked the first one under my 14" band saw. When I saw the high weight capacity I ordered a second one. Assembly takes a bit of time because you want to measure the footprint of the saw and built it fairly close to those dimensions, and decide whis sides you want the wheels and kick stops. Then I built a sturdy platform to sit in the frame using 2x8 oak trailer decking because the legs of the saw are not at the extreme corners, and there is a stabilizing foot that sticks out about 8" from the center of the side facing the operator. I needed to bridge the length and carry the weight to the corner support gussets. Once cut, I drilled through the metal gussets and lag bolted the oak in place from below so nothing could move. Use a hand truck and several people to set the saw on the oak and that frame stayed rigid without any major deflection or issues! This really surprised me because the frame feels relatively light in construction for such a heavy saw. One thing that helped is that I adjusted it to the minimum extension size possible to keep the span lengths short for support. Once I lag bolted the saw to the wood deck, this setup was oak solid and you can roll it around with one hand! The kick stop brakes are nice so you can keep it from rolling in use.

Disppointed in the product, i dont know if its because I had to add the extra coupling and extension piece but it doesnt move easily at all. Its actually arduous to move it. I just assembled it yesterday and it took a long time. I did have to modify the length of the extension pieces because i needed 57 inches and even with everything cinched tight the length was 60 inches so i had no choice but to cut off the extensions length. That wasnt the issue because they give you the size I was just hoping the feet were large enough on the ID of the frame that it would hold the lathe. The disaappintment came with the couplings dragging the ground, I undid all 16 bolts one side at a time and used a crowbar to push up and retighten and the coupings are still dragging on one side and the other side lifted about 1/8 inch. Another disappintment is onewheel doesnt spin freely and got caught on its own frame I had to lift and spin one wheel around to get it to push against the wall where its resting place is in the first picture, the second picture is where I assembled it. Its better than nothing but it really lacks mobility ease in moving it around. I struggled and the video had the guy moving a long table saw with ease.The assembly was really tedious and I had to stop and start again because I was frustrated with getting the wheels assembled there are four washers on eash wheel for the orange flip lock and trying to get them on without the second and third washers falling was just a big issue. I ended up flipping it upright so the third washer install didnt fall down inside the wheel void which the only way to get it out is to take the wheel assembly back apart and flip it upside down to get it out and restart the assembly over. I did everything alone and it probaby took three hours with the wheels being the biggest time consumption.I was really excited because I made my entire work shop mobile and to have spent this much on the extensions, coupling and wheel base and for it to not move easily was a disappointment. It feels sturdy but again the center drags the concrete scratching the floor. Might be easier if there is two people assembling.Its just not the best for mobility but I put all this effort and already cut up one of the extensions so its not like I am going to return it after spending so much time dealing with the assembly and getting a 450 pound lathe inside the mobile rig by myself. Ill just live with it, but you get tired of living with things, you expect it to work as advertised easpecially when you spend a lot for the product.
