1933 BSA Blue Star
« on: 25 March, 2024, 03:20:43 »
Hello,

Does anyone have an anchor plate for the steering damper on a 1933 Blue Star? The part number is 15-5072.

I'd be happy to buy the whole steering damper if there's one out there!

Many thanks

I struggled to find this so after careful study I fabricated mine. I have since found a new old stock one. After seeing the genuine article, I was really pleased how close my copy was. I will change it for rhe genuine article at some point. I can supply some dimensions if required.

Ok. Give me a couple of days to sort the genuine one out and measure it.

Please find attached a drawing of the plate before any bends have been put in. I have tried to mark the positions of the bends.
The return bend has a 3/16 inner radius. I.e. is has been wrapped around a 3/8 bar. The plate thickness is 3/32 or 2mm.
The picture illustrates the profile.
I hope this helps.
