Part of a larger project. I have a broken Dyson full sized vac and am converting the cyclone part to fit onto my old electrolux shopvac for my woodworking tools (Table saw and Router mainly) that are mounted on a Triton 2000 worktable.

This part is so that I can screw in the electrolux pipe (40mm OD and +-5mm pitch) onto the extraction port of the top piece I removed from the dyson.

However, anywhere you want a bulkhead mounted screw in fitting for a compatible vacuum pipe, this will work fine.

Will update as the project progresses:
UPDATE 16 Oct
Added 2 parts.
1) Bulkhead mounted adapter from full sized Dyson tube clip-on connector to press-fit female adapter. This will allow the cyclonic filter to be connected via the existing Dyson pipe to a bulkhead mounted on the table.
2) Press-fit male to electrolux pipe adapter
This screws onto an Electrolux vac pipe. One short section like this is required (and permanently mounted on) each tool e.g. skill saw, Router or whatever. This fitting is simply pressed into the above bulkhead fitting when you change out a tool.
