Steering Brakes

The brake bands are strips of phos-copper.








This shows the band arround one of the clutch drums these strips are fixed to the bottom by 5mm set scews.







These are the brake parts. There are two finished brake levers, one attached to the bell-crank shaft the other is the bell-crank attached to the block which links on to the brake band.

There is also a finished brake lever cover and mount block, plus the parts for the second cover before fabrication. The 'H' is bent to the correct angle and brazed onto the rectangular plate which forms the flange for mounting.After the ends have been brazed on the strake of the H is filed down before the top is also brazed.


The right hand steering brake lever mounted on its shaft. The cover casting is yet to be fitted. This lever was profiled from 10mm steel by CNC. The fluting was milled with a 2mm slot drill
Hand filing was used to achieve the taper, finally the lever made red hot to give it the correct set.








Set up for drilling the lever for the 3mm clamp screw.
