Brakes

The brakes are not a very hard job to do but are complicated by the number of parts and their diversity. In the design of the brake linkage I have tried as much as possible to keep to scale but also to simplify the parts to a more uniform design.

They have also been broken down to ease manufacture using all the tools us modern model engineers have in the armory. A case in point are the brake beams. I don't know how they were made in full size but I decided on a fabrication.

So the brake beams were laser cut plate with machined ends welded on. This at the time looked the easiest way to construct the beams without resorting to high cost RPing or casting.

Parting off these parting tools are awesome, fast as you like and no messing

Beam ready for welding

job done

All four beams welded

equilisers on Tormach

Next job was the equalizers so this seemed a god job for the CNC . I made the Solidworks drawing os i could do all the parts at one setting

Basic shape

First basic shape done

Next job was the brake hangers, an RP pattern then lost wax cast in bronze all that was left wa to drill and ream the holes
