"bacon slicers", I know they are essentially useless but are they available anywhere?

about 2 years ago I made a few sets, they werent big sellers so I canned them. ideally they need to be made for each specific hub. not sure if anyone else produces them.
 
A long time ago I started collecting bits to build a garden gate Norton. I found two frames , both damaged. A friend had an early rigid frame with those forks , unfortunately he was in love with them, - however I've never seen another set which might be available for purchase until now. I've still got oil tank and upright gearboxes , so I'm starting to think about that path again. I think the garden gate frame was originally designed to have friction dampers on the units, and could be made to behave sensibly. A good pushrod motor would be an easy build.
 
knew I had some pics somewhere

There is a guy in Scotland making them but they don't look that good and they are 80GBP plus shipping!, $200US for "bling" is out of my realm.

had they been popular I would of done a big batch CNC, but not worth the hassle making one offs,
I made a few sets to see the popularity, not so popular, maybe in another 10yrs. better to make your own.
 
I could never figure out the true purpose of those rings. Are they supposed to get heat out of the drum, keep it from distorting or both ? For a while they were quite common on racing bikes . Perhaps they were simply intended to make the brake look bigger ?
 
Madass, how much do you charge for an 8 inch Norton backing plate? I've got an old conical hub that I might want to use one day.
 
Drum brakes work by absorbing heat, disk brakes by dissipating it. This device is not likely to absorb much heat until the drum is very hot. By then, you are in trouble.
