I SHOW this month photographs and
drawings of the chassis in various stages, from which the reader will be able to complete
this portion of the work. Obviously, certain of the details will need to be varied as to
measurement according to the engine and gearbox used, but the shape of the parts will, of
course, remain the same. My drawing relates to the 350 c.c. Blackburne engine and the
Albion gearbox. In order to save readers trouble, the address of the former is Burney
& Blackburne, Ltd., Atlas Works, Bookham, Surrey, and the latter, The Albion Eng. Co.,
Ltd., Upper Highgate Street, Birmingham, 12. The hubs for the two front wheels are
obtainable from The British Hub Company, Ltd., Weaman Street, Birmingham, 4. When writing
to them, mention the name of this journal so that they will be able to identify the parts
The Steering Head
I have received quite a number of letters from readers who anticipate that they will have difficulty with the steering head. Accordingly, I have made arrangements with manufacturers, for these to be supplied complete and ready for use and for a nominal sum; I have also made arrangements for my car to be on exhibition in some of the leading London stores, so that readers may man inspect it and check tlicir construction against mine.
This month I deal in detail with the steering. It will be noticed that the steering heads have top and bottom pines on which are placed compression and snubber springs , respectively. These two pins are coupled with 3/16in. angle iron. The bottom angle iron is bolted to the two main chassis members by means of bolts and distance pieces, whereas the top bar of angle iron is anchored to the sides of the main members, by means of pieces of tubing flattened at each end and bolted in position. Each end will, of course, need to be flattened and bent to the required angle, so that the parts fit snugly. They act as tie rods and resist the rocking motion which might result when the brakes are applied.
The Engine Plates
The two transverse cross-members at in front of and behind the engine and gearbox are scoured by means of rods screwed at each end
