Look at the ToolOrbit website again. Although it gives a price, up toward the left on the page it says that this accessory is not currently available. I doubt you will find a source for it anywhere. DeWalt seems to have stopped making them several years ago.
The internal blower in the 735 pushes the chips out at a considerable velocity. The accessory chip hose has a connector that twist locks onto the 735, so it stays attached very well. The only problem that I've had with this accessory is with the draw string that holds the fabric bag part to the top of the collection barrel, and it's mostly my fault for my choice of barrel. The barrel needs to have a significant lip around the top edge so the draw string can hold around it well. I'm now using a blue plastic 55 gallon barrel that has a significant top edge lip and haven't had any problem with it when using this barrel.
If you make your own, find a plastic 90 deg elbow that will fit the outlet port of the 735 and modify it to twist lock attach to the planer - one round hole on one side is for a spring loaded pin, the other needs to be L shaped to twist onto a fixed pin. The pin needs to be pushed in and then the fitting can be twisted to unlock it from the planer port. There is a grounding wire that connects the metal spring in the hose to ground it to the planer frame. It's a good idea to use this to prevent getting static shocks from the hose. The accessory fitting is a straight connection and it would have been better if it was an elbow, because the hose catches on the leading edge of the wood exiting the planer, if not held out of the way somehow. The hose part is nothing special, just very flexible internal spring hose, but it stretches and shortens in length easily, so it can be very short when stored or long, (about 6') when in use. The bag/bonnet portion that attaches to the barrel is a coarse filter fabric to allow air to easily escape through it, but keep the larger chips from escaping. The bottom end of it has a draw string, like a Winter jacket, with a cylindrical spring lock like is found on the bottom of Winter jackets to allow tightening the draw string around the barrel just below the top lip. If you want detailed pictures of any part of this accessory I can post them. The accessory collector works very well, if the draw string doesn't pop off of the barrel.
Some day I will find the right elbow and modify that end of my dust collector accessory so the hose no longer catches on the board being planned. Until then, I'll just lift the hose as the leading edge of the board comes out of the planer.
