You may recall that we had two steering wheels cast from the pattern - one for ourselves and one for Barry. The castings were good, but naturally carried the imprint of the sand on them from the casting process. This has to be cleaned off and the steering wheels had to be finished highly polished.
Barry got right on with his and used a Black and Decker Power file to do the job which made a quick and very satisfactory indent into the process which can be quite time consuming - and also a bit dirty! His initial results are shown in two of these pictures. This was a tool that we were not familiar with but seeing Barry's excellent results, we bought one.
The first job was to put a 16mm hole through the centre of it, ready to take the Broach that Steve is making up to for the final square hole to be made for it to fit the steering column. Fortunately the Colchester Student will take 18" in the gap and we have an 18" Face Plate to which the Steering Wheel was fixed. Straight forward operation to put the 16mm hole in it and to turn the back of the boss to finished dimensions. The dishing of the wheel that way was in our favour.
On our equipment, it was not possible to turn the steering wheel around on the faceplate to face off the other side - as because of the dishing, it would foul the bed - so the only way to face that off was to hold it in the Milling Machine - and do it that way.
But another problem there as the depth of the throat on the Milling Machine is only 9", so we could only machine (by fly-cutting) half of the boss at a time. The Steering wheel then had to be turned through 180 degrees in the milling machine, set up again so that the other part could be machined to match.
