Volumex Supercharger adaptor prototype. ....please click here to open.

 Continued from previous post. Here we have some further conceptual adaptor design work to allow the option of a Volumex supercharger fitted on to the Wolseley Supercharge inlet manifold and belt drive coupling and shaft arrangement.

Alternative Supercharger Fitting design and 3D Printing.... please click here to see

 We have been measuring and designing new templates and adaptors. With the aid of some supplied sketches and our own dimensions, we can consider the possibility for the Wolseley to have an option to use a Volumex supercharger in the future. You can see that we've been using CAD to draw up the various components to carry out a test assembly and assessment within the CAD program. 

The photos show the parts being drawn and also a prototype adaptor being printed on the 3D printer to give a a solid model for trial. Should we wish, this will give the possibility to present a slightly scaled up print for use as a pattern for casting of particular items. It may be more cost effective to cast rather than machining from billet.

Please note, the plastic type of material we use is created from biproduct of cereal production, it is wholly recyclable.

Further updates will follow.

 The adaptors on the printer and CAD drawing at the top of the page, are to suit the inlet manifold fitting of this Volumex. This picture indicates where a bespoke end housing will be made and a drive extension will be taken from the topmost rotor to a belt drive as with the existing Wolseley supercharger arrangement.

Wolseley Hornet Spl Details through September... Superchargers!

On the Bench:

 Here we have been working on superchargers. With some preventative maintenance replacing the hard working bearings and a general checkover. We also have a Volumex to attend to in the same way.

The Wolseley crankshaft has been heat treated, unfortunately without careful masking, keyways and drillings become undersize. Here we are carefully filing and oilstone dressing to make special stepped keys before completing the front section. Initially we used loose keys to aid with the repeated test assembly and setting of gears and sprockets, now it is the final detail that counts.

In the previous post Jacob designed a little oil metering device for the Wolseley on Autocad and 3D printed this prototype. We are testing to gauge the oil feed and flow rate and can now proceed to machine the real thing with only a few changes to the reduced channel section, making it a little more robust.

We have changed to a different gearbox on the Wolseley and so we have altered the first pair of clutch withdrawal fork bushes which were made in Oilite material, they now fit the replacement gearbox. By making bronze sleeves we have been able to re use the Oilite in the slightly larger bell housing. After machining we give each bush a light heating process and then soak in oil until required.
