Flat tanker Druid fork steering stops.

Posted by stephen_crowder at April 16. 2018

I have recently acquired a 1924 Norton Model 18 with Druid forks.

My other model 18 has a combined steering damper and steering stops fitted through the Webb fork steering stem.

With handlebars fitted through the Druid stem on this bike how should steering stops prevent the forks crashing into the tank? ( There are currently no steering stops)

Ive looked extensively at pictures and can’t find how it would have been done.

Any help would be really appreciated.

Steve

Any Flat tank guys out there know how this should be achieved?

For what it's worth - I've looked through my stock of Banbury Run Norton pictures.  The late 1920's ones with Webb type forks have adjustable positive stops fitted on the lug between the head tube and the main front down tube.  But the earlier Druid type don't have the suitable lug.  It does look as though on full lock the lower link spindle would turn just below the leading edge of the tank.  Just a guess - but maybe the forks won't actually hit the tank anyway?  Designs were anyway advancing fast at that time.  Maybe nobody had thought of it?!

I think I've attached a photo of the three generations.  Might help?

As Iain says - there are dozens (hundreds?) of pics on Vintagenorton site.

The forks on this bike do hit the tank well before the lower fork yoke hits the frame.

Ive looked on vintage norton site extensively and as yet no clue.

I could revert to a steering damper and stops setup as per my slightly later bike but it would not be authentic to do so.

The late 20s Webb forks had a similar setup to the 30s bikes with a plate and stops anchored underneath the bottom yoke to just above the front engine mount encorporating the steering damper friction disc.

Anyone with a complete early Druid fork bike will perhaps know??

Just seen a 16h today with a bracket and rubber stops arrangement mounted on the front sidecar mount lug.

This does not look right but anyone with other thoughts?

My understanding is that the earlier machines had no provision for steering stops. My ‘24 model 18 certainly does not have them.

What in this case have you done to prevent the forks and tank coming into contact with each other?

Anyone any further ideas?

If I leave as is the forks will hit the tank and I can not believe this is how it should be.

I must be missing something?

I don't think you are missing anything, I have similar concerns for my '23 Triumph. There appears to have been no original provision to limit the travel on the bars. I have only started to worry about it since having a nice new tank made. Two possible solutions I am considering, neither would be authentic: 1 (already mentioned) Some sort of stop arrangement bolted through the front sidecar mount 2 Replace the bars with a higher rise (2 to 3" should be enough) set that will pass over the tank on full lock. This solution would also improve the ergonomics for me.

Up to the early 20's most machines had bars set high with long sweep back with the front of the tank behind the front swivel axis so bars would rotate above the tank and forks not hit the tank unless turned more than 90 degrees. So presumably nobody worried about stops any more we do today with bicycles.

It's not the bars that come into contact with the tank, it's the rear blade section of the Druid forks. I will try to look at a few bikes in the flesh to compare. Thanks for the replies.
