The following is prototype only, and has not yet been proven.
Shown below are the final versions of the Volumex adaptor set.
Library PhotoContinuing on from our previous post. Through the 3D printed prototypes, we can see our design's accurate fitting and function. We required some minor modifications, considerably easier on a 3D printed object than that of a final machined or cast item.
As a result the drawings can now be prepared and presented into documentation that can easily be understood and shared via email and paper form to any future parties. Shown below are screenshots of the final illustrations, visualising dimensions required for fabrication and any other necessary notes.
We just have do carry out a little more study of the drive shaft and housing, these will be completed and posted shortly.

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.
We have often been asked about finishing fixings during restoration projects.
Well as a bit of a post script .. or in this case pre script! I would like to add this edit and say that recently there has been a definite change. BSF stock is being dropped from many of the suppliers, as a result, the costs are escalating hugely which gives greater strength to the first two points in the following list. It also means that for the first time, I regret we will be charging for new BSF bolts even when in small quantity. We will keep this charge at the cost price.
There are several options and our decision is taken according to budget, originality and purpose.
All of this talk of superchargers has made me supercharge "broodie".
I designed and built and raced "Mistress Quickly" 30 years ago and it was always part of my design brief to allow for later supercharging!
Now, with superchargers around us in the workshop, I began to wonder? Don't tell Mr B. who owns the Wolseley, but......
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.
On the Peugeot 401, we have been attending to some of the final steps, whilst we are waiting for pistons from the machine shop.
In preparation for fitting, all water jacket plates have been thoroughly cleaned up, ready for paint and repair if required. Shown here is one of the end plates, that also acts as a hinge point for a linkage, so not an easily replaceable part. As you can see it has had some serious corrosion over the years, resulting in pitting and breaking through in places! We have cleaned it up with a wire brush and repaired with a filling of braze in the worst of the pitting and holes, it was then cleaned up and dressed true and treated with rust killing solution. We arranged two parallel steel sections in the press to gently straighten out some of the distortion from previous repairs aswell as slight heat distortion from our braze repair.
Here we have the final tests and setting of the supercharger. Although simple in operation, you can see the reason for attention to clearances. The rotor engagement and disengagement are so close, it is critical that we have the timing correct to give the full clearance available. In the video we are only doing about 500 rpm... less than 10% of the actual speed in the car!
We have set the clearances and tested them at three different temperatures, noting the results carefully to a chart. This will be an area to monitor carefully during initial test runs.
Note how my hand restricting the pressure loads the battery powered gun.
We have been waiting for one drive extension shaft bearing to complete the assembly and refit to the engine.

We have been working on some finishing touches, including making some new studs where necessary and making an "indexing" oil flow control to the cylinder head. It is important that attention is given to this area as the use of a sporting cam and increase of RPM will increase the loads of the valve train exponentially. The original union has a fixed restricted path.
Some new studs have been machined as well as various items that had accumulated as "to do" during the build.
Some more Supercharger drive over the last two weeks. All very time consuming as the clock races as if supercharged toward Christmas!
