These planers vibrate a lot. If you put it on saw horses you will need to find a way to attach it securely. Also keep in mind that these planers weigh 95 pounds, so even though they have handles, they are NOT portable. This, and the fact that I really don't have the shop space for a planer made me want to make my 735 easy to store in as little shop space as possible, and move it outside when I wanted to use it.
You do realize that a 30 gallon container with the cyclone type lid will only hold about 60 % of it's capacity before the cyclone action begins spitting chips out. You can't even come close to filling the barrel before this happens This doesn't leave much room in the container to collect the chips. I could create enough chips to fill it this much in just a couple of passes of 10" wide and 10' long hard wood. You will be dumping it frequently if you go this way, and I'm not certain how effective it will be either. I once had one of those cyclone covers for use with my shop vac. It worked, sort of, but I gave it away long before getting the 735 planer, so I really have no idea how well it will work with the 735. I gave mine away free, and that should tell you something about how much I liked it. But we all seem to have to learn this the hard way. Good luck with it.
For vacuuming my small shop floor and collecting chips from my drill presses and scroll saws I now use a re-purposed whole house vacuum with a Dust Deputy in the line ahead of it. This works great for what I use it for, but I wouldn't think of trying to collect chips from the 735 or even the sawdust from my Unisaw with it. A Super Dust Deputy sitting on a 55 gallon barrel and a good 1 1/2-2 hp dust collector would make a great system that should work well with the 735 though. The fan in the 735 might even be able to feed directly into a Super Dust Deputy without a vacuum set up, if you kept the hoses short. Dust Deputies are fantasticly efficient.
I've used several containers to collect chips from my 735, one being a standard 30 gal metal garbage can, one being a square plastic garbage can about the same size, an industrial plastic waste can (about 60 gal), and my latest, a 55 gallon blue plastic barrel with one end cut out. I can easily fill this latest barrel in about one hour of planning. The others all filled much quicker It's amazing how many chips can build up very quickly when using a planer.
Look around for one of these big barrels. Transmission shops, car wash stations, truck fleet repair shops, etc, all receive oils, waxes, and detergents in these barrels and usually discard them when they are empty. Beg for one and they will likely save the next one for you. Some dish detergent and water sloshed around in them will clean them out quite quickly. Then saw the end out, leaving the lip to allow attaching a coarse fabric filter, connect your hose from the 735, either through a tight fitting hole in the fabric or a port mounted in the side of the barrel near the top and it will make a great chip receptacle that won't fill up every 10-15 minutes. The blue plastic barrel that I have doesn't seem to be affected by Sunlight, so I leave it upside down behind my shop when it's not in use. My DeWalt accessory hose and barrel cover get collapsed to it's shortest length, the fabric gets tucked inside it, and it gets put back into the small cardboard box that it came in, which is then set on top of the planer, which is sitting on it's end on the hand truck like miter saw/planer stand. All together and folded up it all takes up less than 3 square feet of floor space in the corner of my shop.
