Vintage Workshop
Services for Brough Superior motorcycles and their contemporaries

SS100 replica project main page

Here we go, what do we need to build a motorcycle? Sorry - not just a motorcycle - a Brough Superior SS100!

A first prerequisite seems to be a decently equipped workshop.
I have looked to this end by upgrading my equipment a little. Do you feel like going on a little tour through my small basement workshop?

Well, then we need to know what to do. This means photos and DRAWINGS!
Please do not expect to find Brough SS100 engineering drawings in your next technical library.
 

Next we need to find or make a lot of components.
Let's start with the engine. A 1927 JAP KTOR 1000cc ohv . My absolute favourite!
If you want to buy one, expect to pay the price of a new 1000cc plastic rocket these days. And do not hope it will just need dismantling, cleaning and putting back together!
If you decide to build one, you might want to know how far I got in the meantime.

The engine needs  carburettor to breathe through. After looking out for a correct AMAL 6/022 carburettor for a long time I have decided to help myself. I built one out of a rather scruffy 6/024 (flange fitting) body...

And you will need a sturdy gearbox. A Sturmey Archer heavyweight 3-speed box will possibly do, but if you can get hold of the SB (Special Brough) type, all the better!
I have collected a few bits and bobs now and made a few new end covers for these boxes.

Another mountain we will need to climb is the frame. Building that means having a complete set of lugs cast in steel or malleable iron, machine them all, find the correct tubes, make a jig to hold everything in place and braze the whole lot up. It can be done, however...

At the frame's front end, we need a fork. A CASTLE fork. Quite unobtainable, but it bears a striking resemblance to a Harley font end, doesn't it?

Frame and forks are cumbersome to move about unless you have a pair of wheels in.
Every wheel builder will lace one up for you, if you supply him a hub (in fact I like to lace up my wheels myself, as I think this is one of the easiest jobs, indeed). To start with, I have made a few 8" rear hubs.

As the above reproduction was quite a venture, I was more than happy that I made the acquaintance of Terry from Australia, who has now made me a front hub.

Oh my dear, now we still need the whole tin ware: two mudguards, toolboxes, primary and rear chain cover, an oil tank, and last but unfortunately absolutely not the least problem: a TANK!  
Then, there is still a host of smaller bits and pieces: Handlebars and levers, steering damper, footrests, rear and side stand, a saddle, all the lighting equipment, a lot of pipes, cables and wires and hundreds of correctly shaped nuts and bolts. Has somebody ever counted the number of bits a Brough Superior consists of?  
Oh yes, recently I got into repairing a broken SMITHS chronometric speedo head...
