Wayne, you could do that using Corwin's approach using the Festool end fittings. Problem is, that Festool end fitting only fits the 2 1/2 inch hose to hose connector. Both ends of the hoses to be joined are fitting with vacuum machine end fittings, and thus, to use your 36 mm hose, you'll have to make up another short adapter hose, or change the end fitting of the 36 mm hose mounted on your boom arm. That is why I wrote my earlier comment - Festool does not appear to offer a solution that allows the vacuum machine end fitting of a 27 mm Festool hose to be simply and directly coupled to the machine end fitting of Festool's 36 mm hose. My solution is to wrap the swivel tool end fitting of the 36 mm hose with a few turns of black vinyl electrician's tape which allows the ID of the vacuum machine fitting of any other Festool hose to be directly coupled via friction fit. You would still need to make up a short piece of Festool hose with the desired machine end fitting to work as you desire, so I think making up a pair of short adapter hoses, one in 27 mm and the other in 36 mm would accomplish your objective and enable use of all Festool components as illustrated by Corwin. I wish Festool would make available some additional adapters, and / or those short hose pieces. Another possibility for people who are considering purchase of hoses, is to get the 5 m (16.5 ft) versions and extra end fittings / adapters which would thereafter enable them to set up a mini-cyclone and adapter hoses at minimal expense.
